Stress Update

Last week i chose two ways to deal with stress and got one assigned from the teacher. my results were pretty much more positive in terms of less stress during the day. Although stressful situations occur a lot around me the stress dealing activities are doing their jobs:
-To Do & Reminder page (procrastination)= actually helping, i keep track of my assignments and always find time to do them without making long hours or prolonged homework sessions
-Eat right (happy stomach -> happy health-> happy me)= Don't feel much difference but definitively make me less worried about me getting fatter and the feeling of guilt is gone
-Find Ways To Distract Myself (stay away from stress for a while)= Great actually spend more time with my friends laughing and having a good time instead of sitting on a corner and whine about my life and hitting walls because of anger...

the stress reduction process is actually working and i think there are many other ways to improve the living of students and also to improve the academic performance of them.

Stress And Hormones

The two types of stress come in short term and long term.
Short term stress basically is what triggers fight or flight and quick response its effect is short depending on the situation.
Long term stress is more of a problem because it involves weakening of important body parts and function such as the immune system and the brain weakening the immune and causing injury to the brain.


my goals for stress reduction would be: * drum-roll*
-find ways to relax.. (i have never used any kind of drugs and never will)
-eat right

Prosthetic Limbs That Feel?!

The Ted Talk of the prosthetic arms that feel is found here

     The Ted Talk talks about how some scientists created bionic limbs that have sensory outputs that allow the brain to pick up the feeling of something they touch. this seems crazy but it actually works it is amazing how science advances and helps people to recover from a variety of things. of course this is on its early stages because its not very practical for all the public and its roughly a fast of a response of a robot but it works. these scientists are working hard to make these arms to work as best as they can make them, it is not like a real arm but it really is worth to have because it enables you to do many of the things that you couldn't do with just one hand. there are many improvements to be made but it is really good to have this available for people that lost their arms in terrible accidents, war, etc.

the prosthetic limbs work with sensors places in other parts of the body to pick up the desired movement, it is very interesting to see and it makes the viewer think about the wonders of science.

Remote Controlled

Remote controlled video is about a cockroach being controlled by using some type of mechanism in the Nervous system, i believe, this is a really odd experiment but it seems to work.


There are always bad things with every new invention, this might enable people to set cameras and use as espionage tools but it also may be good to explore narrow pathways and all kinds of small environments



this is a really cool finding, who would have thought that people would be able to remotely control animals?
this might lead to trouble in terms of animal cruelty organizations and such but it might come in handy in some cases.


These videos are similar to the one i watched and they discuss some things in them:



if possible comment what you think about these experiments and why so

3 questions of Friday 26th of April

What have i completed recently?
-i have been reading a lot and also been trying to keep up with the work and act responsible for once in my life
What have i learned recently?
-I learned many things:
  1.signals in the spinal chord go afferent from the dorsal & efferent from the ventral side
  2.parasimpathetic & somatic reactions are slow
  3.many things about flu viruses in the book
just a few things of all the information covered.
Whats next?
- planning to read even more to finish my book on time and do all my homework this weekend

Flu The Story of The Great Influenza Pandemic of 1918 and the Search for the Virus That Caused it
This book had been a little boring to me until about the end of the first chapter where it started intriguing me, it turns out that this book has much information that flows through your mind making you brainstorm all the possibilities, giving you sources to make connections of what? where? why?, the pandemic went all over the world killing between 20 million to 100 million, and the reason is not known or i haven't gotten that far yet.
Chapter 1:
- The influenza summary: where it started and what happened in 1918, there were many theories of how it flourished. this organism was said to be some type of war weapon from Germany but nobody knows. this influenza was known for its horrific numbers of deaths. As the title of the chapter says it explains The Plague Year. only a year a disease that had disappeared and reappeared stronger in that same year and completely vanished afterwards.
Chapter 2:
Hospitals were filled with the ill suffering from the pandemic
-This chapter goes back in time to the times of the first epidemics and the patterns they presented. it also explains some pathology towards the mysteries of early diseases such as cholera and other types of influenza and Black Death. it discusses the germ theory that was newly introduced in the 1918 period and how it fitted when cholera was stopped. it is very interesting to see how some diseases infected the whole world but it's also intriguing how the pathology of this Flu is so different from the other epidemic diseases that struck the world in the early ages of science.  unrelated to the book the video is a documentary about the 1918 flu to get more information opinions and facts

Leech Dissection Online Lab

Leech Dissection Online Lab

The Leech Dissection Lab gave me an idea of how many varieties are there of everything, if we have different kinds of receptors of feeling what else is there?

The disection was very interesting, what caught my eye was the way the reactions were expressed in the micromanipulator, the reactions of the cells were very interesting overall.

in the The Neurophysiology Lab you can appreciate the actual lab. there is some background to it so it would be a good idea to check that first.
Leches' background info in the lab

overall it was a great experience that i would have liked to had made in person but i guess this is okay.

How Does the Brain Work: Hypothesis

 Everybody knows how the heart works, if you ask anyone they will tell you something like, "well it pumps blood all over the body", but then:

how does the brain work?

     Before any research on this, my guess of how does the brain control everything is by electrochemical signals/impulses. The brain uses impulses to signal what to do. these electric impulses are what it makes us do everything; open our eyes, get out of bed, etc. we move our muscles because we tell our brain to send these electric impulses to our muscles through efferent pathways, these are passed through the spinal chord and sent to the desired muscle by efferent neurons all the way until the movement happens, this is a very fast process. the Brain and spinal chord is the CNS (Central Nervous System) and everything else is PNS (Peripheral Nervous System)




Electrochemical impulse

                                      CNS + PNS

Anatomy of Skeletal Muscle..

The anatomy of skeletal muscle is not very complex. It could be explained as just "Tubes within tubes".

First tube from out-in is basically the muscle itself; the outermost layer of the muscle which is epimysium. epimysium is the "membrane" that holds smaller tubes of Perimysium the second biggest "mysium". then comes the endomysium which is the smallest of these. inside the endomysium tubes are located in. These tubes are muscle fibers which are basically the cells. inside the cell there are more tubes of myofibril. These myofibrils hace whats called a sarcomere which is composed of two myofilaments, these are Actin and Myosin.

Actin is the thin filament and Myosin is the thick filament.
these two are the main part of the sarcomere(The smallest contractile unit.) 
To contract, the myosin uses ATP to form a cross-bridge with the atin the myosin then slides the actin making the H zone dissapear.

3 Questions of friday 22nd of march

1- What tasks have i completed?
= recently i have been doing a little studying of the muscles, and a little coloring too. i have been doing my flipped notes and trying to catch up on everything else.
2-what have i learned?
=basically i have learned new things about the sliding filament theory and the physiology behind it.
3- what's next?
= I am planning of spending an hour a day (or more) doing homework sometimes i find homework confusing or hard so i'm also planning on going to get help in lunch hours to really retain more important information.

My Book

My Book!

     I am currently reading "FLU The Story of the Great Influenza Pandemic of 1918 and the Search for the Virus That Caused It" right now I stand in the very beginning i have read it about 3 times because i'm having trouble understanding it completely. honestly it brings me a headache but i'm planning of reading it more often. So far the book has given me information about the 1918 flu and it seems like its also a good story about those times, i have learned a few things about the 191 lifestyle and also some theories about how it got here, for example it said the it came in U-boats, or in medicine from Germany and such. i hope this book don't turn out to be boring because it looks like it has a nice story behind it.

Skeletal + Integumentary

Skeletal + Integumentary

The integumentary system is basically the skin. the skin has many functions: -to maintain homeostasis. -to maintain borders. -to protect internal organs among a few more different functions. the skin like all the systems is incredibly important for many issues.

The skeletal system is more about protection, support, red blood cell making, and storage:
-protection-
~the skeletal system protects by covering important organs with bone to anchor and protect from collision/
-support-
~this system supports the weight of the body in the vertebral column. the vertebral column consists of cervical, thoracic and lumbar vertebrae. all of them support the weight of the body.
-storage and cell making-
~ the bones have yellow (in adults) and red (in children) marrow. yellow is for storage because is mostly fat. Red is designed for production of red blood cells.
The skeletal and integumentary system have something in common. both protect internal tissue. the skin and skeleton protect the skeleton is hard like reinforced concrete and the skin absorbs the impacts, maintains boundaries to maintain its physiology going. this is all about homeostasis.

Skin, The anatomy

The Skin
     The purpose of the skin is to protect and maintain boundaries. It keeps the parts below it safe. it keeps water in the body. The skin consists of three main layers. The Epidermis: the top later of the skin. The Dermis (the layer below the epidermis). and the Hypodermis. 

To see a slide of skin click here

The Epidermis:

The Epidermis consists of the outer skin, it is keratinized stratified squamous epithelium. it has sweat pores and hair. in other cases such as the skin in palms and feet the epidermis only has sweat pores and without hair.

The Dermis:

The Dermis is the second layer of the skin, this one much more complex than the epidermis. inside the dermis you find connective tissue, it has macrophages, fibroblasts. within, you find elastic and reticular fibers that give it the elasticity and strength it has. in here is where you find capillaries. and in the gelatinous fibers you can find collagen.

The Hypodermis:

The Hypodermis is the deepest layer of the skin. In this part of the skin is where fat cells reside. it is composed of adipose tissue. The fat in this part of the body help to absorb shock to protect the underlying organs

Silk Tissue??

Tissues made of silk?

     In the TED talk, Flo Omenetto, gives a speech about silk. his speech was about making all kinds of things with silk, among these things he says that it is possible to make things such as tissues, bones for instance since its very useful for protection. he also talks about making cups, microscopic needles, and others as micro electronics, tools, such as bolts and nuts that work underwater etc. all this is very important for science because it can help in many issues like implanting tissues without immune response.




The silk has many purposes to help. mainly the thing that is more important is bone making, if it is possible to make them it could help many people in the world that need tissue. getting it from silk is much better, it would help all kinds of fractures and more serious injuries.

Something i am passionate about

1)-Okay firstly I guess I have to introduce myself: my name is Manuel, but people have the option of calling me: Manuelayto, Josie, Manny  or Flowerz. i am interested in science because i search a career in the medical field and I am very much into music.this leads to my topic:

2)What i am passionate about: To give you guys a hint you can go to this website here and you will see a pretty cool video about my passion. as boring as that could get to be i love most kinds of music and i have knowledge on some instruments. another point is as you can see is music such as RnB/Soul.
i love music but this is my favorite. i have a passion about piano (even though i don't know much) i love to learn new songs and play them because that's the thing i like to do, to distress my mind. so what am i passionate about? i am passionate about music
