| a nerve cell; the basic building block of the nervous system |
|
|
Term
|
Definition
| a neuron's bushy, branching extensions that receive messages and conduct impulses toward the cell body. |
|
|
Term
|
Definition
| the neuron extension that passes messages trough its branches to other nerons or to muscles or glands. |
|
|
Term
|
Definition
| a fatty tissue layer segmentally encasing the acons of some neurons; enables vastly greater tansmission speed as neural impulses hop from one node to the next |
|
|
Term
|
Definition
| a neural impulse; a brief electrical charge that travels down an axon |
|
|
Term
|
Definition
| the level of stimulation reqired to trigger a neural impulse |
|
|
Term
|
Definition
| the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft. |
|
|
Term
|
Definition
| chemical messengers that cross the sunaptic gaos between neurons. when released by the sending neuron, neurotransmitters trvel accross the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse |
|
|
Term
|
Definition
| a neurotramitter's reabsorption by the sending neuron. |
|
|
Term
|
Definition
| morphine within - natural, opiate-like neurotransmitters linked to pain control and pleasure |
|
|
Term
|
Definition
| the body's speedy, electrochemical communication network, consisting of all the nerve cells of the preipheral and central nervous system |
|
|
Term
|
Definition
| the brain and spinal chord |
|
|
Term
| peripheral nervous system |
|
Definition
| the sensory and motor neurons that connect the central nercous system to the rest of the body. |
|
|
Term
|
Definition
| bundled acons that form neural cables connecting the CNS with muscles, glands, and sense organs. |
|
|
Term
|
Definition
| neurons that carry incoming info from the sensory receptors to the brain and spinal cord |
|
|
Term
|
Definition
| nueorns that carry outgoing info from the brain and spinal cord to the muscles and glands |
|
|
Term
|
Definition
| neurons within the brain and spnal cord that communicate internally and intervene between the sensory inputs and motor outputs |
|
|
Term
|
Definition
| the division of the peripheral nervous system that controls the body's skeletal muscles. also called the skeletal nervous system |
|
|
Term
|
Definition
| the part of the peripheral nervous system that controls the glands and the muscles of the interna organs. its sympathetic division arouses; its parasumpathetic division calms. |
|
|
Term
| sympathetic nervous system |
|
Definition
| the division of the sutonomic nervous system that arouses the body, mobilizing its energy in stressful situations |
|
|
Term
| parasympathetic nervous system |
|
Definition
| the division of the autonomic nervous system that calms the body conserving its energy |
|
|
Term
|
Definition
| a simple, sutomatic resoinse to a sensory stimulus, such as the knee-jerk response |
|
|
Term
|
Definition
| the body's slow chemical communication system; a set of glanfs that secrete hormones into the bloodstream |
|
|
Term
|
Definition
| chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues |
|
|
Term
|
Definition
| a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in time of stress |
|
|
Term
|
Definition
| the endocrins systems' most influential gland. under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands |
