Neural Communication
10
Dendrites:a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
Neuron:a specialized cell transmitting nerve impulses; a nerve cell.
Axon:the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells
Myelin Sheath:The cover that surrounds many nerve cells and helps to increase the speed by which information travels along the nerve.
Action Potential: the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.
Threshold:the amount of energy needed for a neuron to cross over
Synapse:a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter
Neurotransmitters:a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
Acetylcholine:a compound that occurs throughout the nervous system, in which it functions as a neurotransmitter
Endorphins:any of a group of hormones secreted within the brain and nervous system and having a number of physiological functions. They are peptides that activate the body's opiate receptors, causing an analgesic effect.
