Step 2
GRAY MATTER | WHITE MATTER |
It is darker tissue of the brain and spinal cord consists of nerve cell bodies | It is paler tissue of the brain and spinal cord consists of nerve fibers |
Composed of cell bodies, axon terminals, dendrites | Composed myelinated axons of nerve cells |
Highest development identified in the twenties | Highest development identified at the middle age of life |
Process received information from white matter and sends the instructions back to the effector organs through the white matter | Transmit both sensory and motor impulse between the peripheral nervous system and the gray matter |
Controls the senses of the body such as hearing, feeling, seeing, speech and memory | Controls the involuntary functions of the body such as blood pressure, heart rate and body temperature |
