The Brain and Nervous System - Central Peripheral 8.2
12
reflex : An action that is performed without conscious thought as a response to a stimulus.
stimulus : A thing or event that evokes a specific functional reaction in an organ or tissue.
response : A reaction to an act or sense in which stimuli trigger.
peripheralnervoussystem : The nervous system outside the brain and spinal cord.
centralnervoussystem : The complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
cerebellum : The part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity.
cerebrum : The principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres.
axon : The long threadlike part of a nerve cell along which impulses are conducted from the cell.
dendrite : A short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
impulse : A sudden strong urge or desire to act.
cellbody : The soma (pl. somata or somas), or perikaryon (pl. perikarya), or cyton, is the bulbous end of a neuron, containing the cell nucleus.
synapse : A junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
