not that nervous after all. :D
oh my. this cause me so much, i mean VERY MUCH HEADACHE when i'm doing the outline of this. it feels crazy. haha. well anyway. be serious. SERIOUS. okay okay? :)
let's go to the main event. the nervous system. part two. as in 2. ok ok.
the nervous system contains the brain and cranial nerves. they represent the major processor and director of the entire system. here's the thing. brain processes, and the cranial nerves helps in feeding the information to certain parts of the body whose information is needed.
anatomy. let's start from the outside. it is its external anatomy. first. in the cerebrum, you can see the grooves and ridges on it. it is called the sulci and gyri, respectively. these two together is called convolutions. they are important because it keeps the brain small, and occupy smaller space. also, it has four lobes: frontal (for motor activities), parietal (for body sense), occipital (for vision), and temporal (for hearing && emotions). on the other hand, cerebellum acts as the little brain because it has a role in sensory and motor coordination and balance. then, brain stem has three sections: medulla oblongata (responsible for impulses), pons (for breathing), and midbrain (acts as a two-way conduction pathway).
now, let's go deeper. internal part. cortex is the gray matter that surrounds the white one. nuclei as the deep "islands" of gray matter that surrounds the white matter. ventricles are the fluid-filled cavities in the brain that is continuous with the central canal of the spinal cord. in cerebrum, there is corpus callosum or the collection of white matter surrounding the lateral ventricles. by the way, diencephalon has several parts: thalamus (relays and processes information going to cerebrum), hypothalamus (for regulation), pineal body (for secretion of melatonin), and pituitary gland (secretes hormones for several functions). cerebellum has the arbor vitae that acts as the tree of life. cranial nerves are like spinal nerves that serve as pathways in PNS for the brain.
there are other systems: somatic, motor and autonomic. others are limbic and retricular.
hm. how would i explain this?? hm. i have no idea. but with interactive reference materials, and educational games related to this topic, well, i could explain this in those terms. :D
if i were the teacher, i would let them do what they want to do. and let them identify which part of the brain works when they do that. also, i will allow them to answer mazes that would connect and identify how things go in the brain. :) well, thanks sir gregg for simplifying the topic and letting us approach in a lighter way. :)
