♥This week, I have learned about the nervous system part two. This is just a continuation of the report of Christie, but it was reported by Anne.

On this topic, we have discussed the brain and its internal and external, diseases of nervous system, and other more systems that are connected on this lesson. About the brain? I can say that the brain is consist of cerebrum, cerebellum, and brain stem. The cerebrum is the largest part of the brain...here we can find gyrus or ridges and sulcus or grooves. Cerebrum is divided into left and right hemisphere by longitudinal fissure, here also we can find four lobes namely: frontal lobe, parietal lobe, occipital lobe, and temporal lobe. On cerebellum, I can say that is is called as "littlebrain" well, it plays important role in sensory and motor activities. Brain stem is a stalk like structure inferior and covered by cerebrum.

In the brain also we can find cortex or gray matter surrounding white matter and deep islands of gray matter that is surrounded by white matter which is called nuclei. Ventricles, it is a fluid filled cavities in the brain. The diencephalon is also in the brain, it is a section of the brain which is not visible from exterior image. It consist of : thalamus, hypothalamus, pineal body, and pituitary gland. Hmm? thats all i can clearly remember and mention, some of the topics here are already discussed two weeks ago.

My comment: It would have been better if the reporter showed some picture in her report since its a power point presentation, and should have mentioned every terms clearly and not fast...also :) the picture that Sir Gregg asked us to draw is somewhat hard because im not good in drawing :). I suggest that...Sir Gregg will explain it further. :)
