Document Summary
Consists of the central nervous system (cns)(made up of brainand spinal cord) and the peripheral nervous system (pns) (consists of nerves that go to muscles and organs) We can divide the pns into somatomotor (going into skeletal muscles) and autonomic (going to other organs) nervous systems. 2 cerebral hemispheres right and left left hemisphere: sends signals to active muscles on right side of body, sensory info from right side of body travel to left hemisphere, and vice versa. Brain stem controls basic bodily functions (heart rate, respirations: made up of midbrain, pons and medulla oblongata(medulla is continuous with the spinal cord. Diencephalon: consists of thalamus and hypothalamus. Bumps of the brain are called gyri. Dips of the brain are called sulci. All gyri and sulci are same in everyone. Each hemisphere is divided into 4 lobes these folds increase the surface area of the brain. Neurons only make a small amount of brain.
