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: ^^^^
