| Neuron | nerve cells
🗑
|
||||
| Dendrite | branch off the nerve cell where other cells receive impulses
🗑
|
||||
| Axon | thread like part of the cell that sends a revives impulses throughout the body
🗑
|
||||
| Axon terminal | connecting point of the nerve cells
🗑
|
||||
| Action potential | the change of election potential
🗑
|
||||
| Resting potential | amount of energy when not stimulated or in the passage of impulse
🗑
|
||||
| All-or-none principle | strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus
🗑
|
||||
| Synapse | a meeting point between two nerve cells
🗑
|
||||
| Neurotransmitter | 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
🗑
|
||||
| Sensory nerves | carries sensory information toward the central nervous system
🗑
|
||||
| Interneurons | a neuron that transmits impulses between other neurons, especially as part of a reflex arc
🗑
|
||||
| Antagonist | a muscle whose action counteracts that of another specified muscle.
🗑
|
||||
| Agonist | a muscle whose contraction moves a part of the body directly.
🗑

🗑
|
||||
| Endocrine system | Refers to the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs.
🗑
|
||||
| 21. Hormone | a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action
🗑
|
||||
| Pituitary gland | the major endocrine gland. A pea-sized body attached to the base of the brain, the pituitary is important in controlling growth and development and the functioning of the other endocrine glands.
🗑
|
||||
| Nervous system | the network of nerve cells and fibers that transmits nerve impulses between parts of the body.
🗑
|
||||
| Soma | the parts of an organism other than the reproductive cells. The body as distinct from the soul, mind, or psyche.
🗑
|
||||
| Myelin sheath | A fatty white substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.
🗑
|
||||
| Refractory period | a period immediately following stimulation during which a nerve or muscle is unresponsive to further stimulation.
🗑
