Neuron
nerve cell
1 of 16
sensory neuron
neuron that carries an impulse from a receptor to the CNS
2 of 16
motor neuron
nerve cell that carries information from the CNS to a muscle or a gland
3 of 16
effector
an organ or cell that carries out a response to a nerve impulse
4 of 16
Synapses
junctions between two nerve cells
5 of 16
Central nervous system
brain and spinal cord
6 of 16
Peripheral nervous system
parts of the nervous system - not in the spinal cord or the brain
7 of 16
Excitable tissues
tissues that are capable of being activated by ans reacting to stimuli
8 of 16
cell body
the portion of a nerve cell that contains the nucleus but does not incorporate the dendrite or the axon
9 of 16
dendrite
highly branched , slender process from a nerve cell
10 of 16
axon
long thread that carries impulses from the cell body to the target cells
11 of 16
myeline sheath
insulating sheath around a nerve cell
12 of 16
Schwann cells
cells that surround myelinated nerve cells insulating them
13 of 16
node of ranvier
small gaps in the myelin sheath surrounding a neuron
14 of 16
Na+ K+ ATPase pump
the enzyme based mechanism that maintains correct cellular conc of sodium and potassium ions by removing excess ions from the inside of the cell and replacing them with ions from outside the cell
