Nervous System Part 2

Uhmmm....this week, our lesson was the 2nd part of the nervous system. I learned all about the Internal and External Anatomy. I learned about the 3 major parts of the brain, the cerebrum, cerebellum and brainstem. I learned about the gyri and the sulci. I also learned about the 4 lobes of the cerebrum. The parietal,occipital,frontal and temporal lobes.I learned about their uses. I also learned about the midbrain, medulla oblongata and the pons of the brainstem. I also learned about the cortex and nuclei, ventricles and also the diencephalon. I learned about the thalamus, hypothalamus, pineal body and pituitary gland of the diencephalon.

If I were to discuss this topic, I would discuss with the use of powerpoint, also images for better understanding. I would suggest nothing for this topic since the reporter did a good job in discussing this. =D

Nervous System

Hmmm...from what I remember in this topic, the nervous system is like the computer for the whole body.I have learned about the Central Nervous System and the Peripheral Nervous System. There are 2 types of cells for the nervous tissues. One is the Neuroglia or the Glial cells and the other one are the Neurons. I have learned about the meninges and its 3 layers.

If I were to explain this to someone, I would use a powerpoint and some charts to let the others easily understand this topic.

The reporter Christy gave a somehow good report on this one. Her charts are somehow messy but still understandable =D

Integumentary System

Let me think...from what I've learned, integumentary system is the one in charge of the skin and its accessory components I think. There are many functions of the Integumentary System, for example, it regulates body temperature, it covers the other organ systems, it gives sensory input, it keeps the pathogens out from the body and other vital functions. This has 3 layes namely epidermis, dermis and subcutaneous fascia. All of the layers have their specific functions. There are also 4 types of burns each pertaining from the level of the burn. Well, that's all I remember....I think? =D

I would use a powerpoint to discuss this for easier understanding of the lecture =D

Muscular System

Muscular system...from what I learned, I know that muscular system provides the movement for the whole body. There are 3 kinds of muscles:smooth, cardiac and skeletal muscles. Smooth muscles are involuntary muscles found in all of the organs for contracting and relaxing routine except in the skeleton, and the heart. Cardiac muscles are the involuntary muscles in the heart obviously. And then skeletal muscles are voluntary muscles found in bones. I also learned about the diseases of muscles, different names of muscles, and others related to muscles.

Hmm..I would prefer to teach this lecture in a form of powerpoint presentation for easier understanding. Like what our teacher does, or give this to others for reporting so that it would be easier to know if he/she understood the topic well. :D

Skeletal System

Hmmm....skeletal system...the skeletal system has many functions. These include protection, support, body movement, storage of minerals and production of blood I think. Also, the skeletal system is the framework of the human body. There are four classification of bones according to their appearance: long bones, short bones, flat bones and irregular bones. I also learned about bone anatomy. For example, periosteum is the component that cover up the bones. I also learned the formation of bones, structures of bone, names of bones and many others (of course regarding bones).

If I were to teach this lecture, I would use powerpoint or show illustrations of flow charts for discussion. =D

Our teacher, Sir Gregg, taught us this lecture well. (Keep up the good job sir!) =D

Anatomy and Physiology

Uhmmm...this was the first lesson that we had in our advanced biology. Since biology is said to be related to anatomy and physiology.

Anatomy, I think, is the study of structures of plants, animals and humans. There are two kinds of anatomy, gross anatomy and microscopic anatomy. Microscopic anatomy is anatomy of very small things that can not be seen by the naked eye. While gross anatomy is anatomy of things that can be seen by the naked eye.

Physiology is the study of the functions of the structures of the body.

Well, that's what I learned from this topic.

Suggestions? I won't suggest any since the style of teaching is good for me. =D

Lipids

Lipids from what I know and what I hear, I think of fats. Lipids are divided into two groups which are simple lipids and complex lipids.

Simple lipids have no fatty acids, and are also non-saponifiable. Under simple lipids are terpenes, steroids and prostaglandins. Complex lipids are like the opposite of simple lipids (obvious from the name right?), complex lipids have fatty acids, and complex lipids are saponifiable. Under complex lipids are waxes, acylglycerol, phosphoglycerides and sphingolipids.

That's what I know about lipids. I suggest for you to use concept maps or charts to show the classifications. Like what our teacher did, it made us easy to understand.

Cells @_@

If I remember correctly, the cell is the basic unit of life, and it makes up tissues, organs, systems and organisms.

There are 3 parts of the cell, the nucleus, cytoplasm and the cell membrane. The cell membrane server as the wall of the cell. The nucleus is known to be the brain of the cell, it controls the cell. Nucleolus are also found in the nucleus. Then the cytoplasm, the organelles of the cell is found here, for example golgi apparatus, ribosomes, lysosomes and etc.

Hmmm...I'd like to comment that our teacher showed us pictures and images of these and also he made the class very active so that all of us would participate in the lecture.

Mitosis :|

Hmmm....Mitosis is another type of cell division based from what I learned from the lessons. It seperates the cell into two and each with 23 chromosomes. There are 5 stages of mitosis I think and those are interphase, prophase, metaphase, anaphase and telophase.

The first phase, interphase, is the phase where the parts of the cell is still complete and the chromosomes are still coiled. Prophase then comes in, the spindle fibers become visible,the chromosomes become uncoiled, and the nuclear membrane degenerates. The next phase is metaphase where all the chromosomes go to the equatorial plate or to the middle line of the cell. Then anaphase is next, where the spindle fiber attaches to the chromosomes and pulls then to the opposite ends making the chromosomes split up. Then, the last is telophase wherein the two daughter cells are formed.

This topic is an explanation that I learned from our teacher, Mr. Manalo. We all enjoyed this topic since we were all very participative that time.

Meiosis

Hmmm..well from what i have learned,..meiosis is a type of cell division which is a one way process. It means that it does not repeat itself.

Meiosis has 2 phases:
Meiosis 1 and Meiosis 2

Before Meiosis starts, there would be an Interphase 1 in which the chromosomes are duplicated. Then, Meiosis 1 starts with Prophase 1, followed by Metaphase 1, Anaphase 1 then Telophase 1. After that Interkinesis follows, then Meiosis 2 which is identical to Mitosis.

Meiosis always results in gametes and should have a total of 92 chromosomes I think?

Hmmm if I would have to teach the class I think I would make the class lively to get things going but not too much, and I would want to perform activities that would make the students more interested in the topic like what our teacher Sir Manalo does =D. I'd comment that our teacher does a great job in teaching us in the lessons =D.
