star-shaped neuroglial cell between neurons and blood vessels
nerve fiber arising from a slight elevation of the cell body that conducts an impulse away from the cell body
branch of an axon
neuron process with many tiny. thornlike spines that conducts an impulse toward the cell body
substance of schwann cell composed of lipoprotein that insulates axons and increases impulse speed
sheath of schwann cell containing cytoplasm and nucleus that encloses myelin
network of fine threads of actin within cell body
nissl bodies (chromatophilic substance)
corresponds to rough endoplasmic reticulum in other cells
structure capable of responding to motor impulse
cells that cover the inside spaces of the brain ventricles and secrete CSF
specialized mass of neuron cell bodies outside the brain or spinal cord
interneuron (association neuron)
transmits impulse from sensory to motor neuron within central nervous system
phagocytic neuroglial cell
motor (efferent) neuron
transmits impulse out of the brain or spinal cord to effectors (muscles and glands)
myelin-forming neuroglial cell in brain and spinal cord
sensory (afferent) neuron
transmits impulse into brain or spinal cord from receptors
