here we go!
that's all thank you! :))
nervous system part two!
here we go to part two! this part discusses mainly about the brain.
the main parts of the brain is the cerebrum, cerebellum and the brain stem.
the cerebrum is where the parietal, frontal, temporal and occipital lobes are found. there are also sulcus and gyrus that can be found in it.
the cerebellum is considered as the "little brain"
the brain stem has 3 parts: the midbrain, pons and medulla oblongata.
we also had an activity and that is to draw the internal and external parts of the brain. it's very helpful for us to remember the parts easily :)
nervous system part one!
for this week, we discussed about the nervous system but since its a very long topic, this is only part one.this part focuses mainly on the CNS.
so there are two types of nervous tissues: the neuroglia and neurons. under the neuroglia is the astrocytes, microglia, ependymal cells and oligodendrocytes in CNS and schwann and satelite cells in the PNS. There are many words and terms that i heard but i cannot remember their definitions anymore. :)
In discussing this topic, its better to summarize i tas briefly as possible so that it would be more understandable :)

integumentary system :)
This week, we discussed about the integumentary system--the body's protective covering.
As I've said, this system protects our body and helps keep the body from drying out. It also acts as storage for fatty tissue. It is also very important in the regulation of body temperature.
<<<>
The epidermis is the layer of skin that we usually see.
there are no blood vessels present there but it has 5 or 6 smaller layers.
the layer next to the epidermis is the dermis. actually, i don't know much about it but it is where the sudiferous or sweat glands are located. there are two types of sweat glands: apocrine and eccrine
the innermost layer of our skin is the subcutaneous fascia (?) or hypodermis. it's composed of elastic and fibrous connective tissue and also fatty tissue.
the integumentary system also includes the nail and hair but.. i don't know much about them c:
this can be reported effectively even with just an illustration (well,..that's my opinion)

muscuLar system :)
If you'll ask me, I can say that visual aids are really important in reporting something. I don't know but.. the reporter doesn't even have visual aids so i found it hard to cope with the lesson. :)
Well because of that, there's no other choice but to read and study it myself. Luckily, I've learned something! Here it goes....
The word 'muscle' is a general term for all contractile tissue. there are three types: skeletal, smooth and cardiac muscles.
skeletal muscles, as its name suggests are attached to the bones. muscles and bones are connected by broad sheets of connective tissues called aponeurosis. skeletal muscles are responsible for external movements.
..smooth muscles are found in all the organs EXCEPT the heart. its also capable of expansion and contraction.
while cardiac muscles are (obviously) the heart muscles. it form the walls of the heart.
..i guess that's all..
.,i would suggest that if you would report something, be prepared so that those who are listening to you would understand your report.=p

skeLetaL systeM ^_^
After all the examinations for the first quarter, here we go again! Back to normal! Lessons..lessons and lessons.
The first lesson for this quarter is about the framework of our body. it is none other than.... the skeletal system.!
Framework and support, these are the well known functions of this system but i learned that it also produces blood cells, provides protection, helps us to breathe, stores minerals and allows movement. well, it's really that important to us.
The primary components of the skeleton are the bones. bones can be classified as long, short, flat and irregular (do i need to say more? i think its self-explanatory). the basic parts of the bone are the epiphysis (bone end), diaphysis (region between the ends), periosteum (connective tissue covering the bone) , medullar cavity (storage for bone marrow) and uhmmm.. are there more? (of course!) well, i cant remember anymore.
There also two types of bone tissues. The compact and spongy. Compact tissues are dense and hard while spongy ones are.. well... like a sponge.. have lots of holes.
We also discussed about bone growth and repair but unfortunately, i already forgot terms about it. c:
While the reporter was discussing, i can't help but feel very very very sleepy! the report should have been better if the reporter made her presentation less wordy and with organizational charts and graphs. c:
we also had an activity! the class was divided into 3 groups to perform a 'skeleton dance' (is that what you call that?). i think we looked as silly as the picture above! hahaha cc: ^^^^

♥♥ Lipids....
Whenever I encounter the word Lipid, the first thing that comes to my mind is that lipids are the fats. Which is quite correct..right?
So Lipids are divided into two groups: Simple Lipids and Complex Lipids.
Simple Lipids have no fatty acids and because of that, simple lipids are also non-saponifiable. Terpenes, Steroids and Prostaglandins are simple lipids.
Unlike simple ones, Complex Lipids contain fatty acids, making it saponifiable.There are four groups of complex lipids: waxes, acylglycerols, phosphoglycerides and sphingolipids ( I hope I spelled them all correctly).
Using a concept map will help in discussing this topic.

Proteins! :)
Proteins...proteins...proteins.... what are proteins?
I'm sorry but I cannot give you the exact definition of proteins. haha. But...I know some information about proteins.. I learned them from our Biology Classes.
Proteins are the most abundant organic molecules in cells. There are four types of proteins..enzymes, hormones, antibodies and amino acid.
Enzymes are catalysts. What are catalysts? I don't know. Well anyway, enzymes speed up chemical reactions.Hormones are chemical messengers that transports messages in the body.Antibodies responses to the presence of antigen or foreign bodies.While Amino acids are the building blocks of protein.
I guess that's all that I can remember about proteins right now.
Oh, I almost forgot...suggestions! hmmmm.. discuss it with a presentation i think...

~Meiosis...hmmmm...i'm a little confused at this topic...but I'll try my best to recall something about it.
Well, unlike Mitosis, Meiosis is not a cycle. It is a one-way process.There are two parts, Meiosis 1 and Meiosis 2. Meiosis 1 starts with Prophase 1 since Interphase comes before Meiosis. There are five stages in Prophase 1. These are Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.After Prophase 1 comes Metaphase , Anaphase 1 and Telophase 1. After that, there will be a resting period which is Interphase 2.Then, Meiosis 2 will start. I think Meiosis two is similar to Mitosis...hmm..but I'm not sure.
I cannot think of any teaching suggestions in teaching Meiosis. How can I? I cannot fully understand this topic. :( ~

The Cell ^_^
Two years ago, when I was still a sophomore student, I encountered the same lesson in our Basic Biology class so I already have the ideas for this topic.
The Cell...the basic unit of life.
A Cell has three basic parts. The Cell Membrane, The Nucleus and The Cytoplasm.
So the Cell Membrane serves as the barrier of the cell. It also gives shape to the cell. It’s found in the outer part of the cell as you can see in the illustration above.^^^
Next one, the Nucleus. It is the "control center" of the cell. It’s that pinkish "circle" in the illustration. As you can see, there is a smaller "circle" inside the nucleus. That is the Nucleolus where RNA is being synthesized.
Lastly, the Cytoplasm. It is where the organelles or little cells are. The are lots of organelles like the ribosome, mitochotria, Golgi apparatus, lysosomes, centrosomes, centrioles , endoplasmic reticulum and other more which I cannot remember at the moment.
Well, in teaching this particular lesson, it's better if you'll present it with illustrations or even simple drawings, like what our teacher did. :))

♥ An Introduction to Anatomy and Physiology ♥
Since we are having Biology classes, we cannot avoid this lesson. Biology is somewhat related to Anatomy and Physiology, right?
So, Anatomy..as far as I can remember is the study of structures. Am I right? Well there are two divisions of Anatomy: Microscopic Anatomy and Macroscopic or what we call Gross Anatomy. Obviously, in Microscopic Anatomy, you'll need a microscope to see and study microscopic structures. While in Macroscopic or Gross Anatomy, you'll just need your naked eye to observe and examine.
Physiology, on the other hand concentrates more on the functions of structures. So in that aspect, maybe it is more difficult and complicated than Anatomy.
Teaching suggestions?..hmmm....well it's just a basic topic, it's easy and like what is on the title, it's just an introduction so it won't be that hard to explain it. ^_^
