A&P Lab, Final Exam, Exercise 25

star-shaped neuroglia 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

corresponds to rough endoplasmic reticulum in other cells

branch of axon

neuron process with many branches that conducts an impulse toward the cell body

substance of the 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 extending into nerve fiber

structure capable of responding to motor impulse

cells that cover the inside spaces of the brain ventricles and help regulate cerebrospinal fluid

specialized mass of neuron cell bodies outside the brain or spinal cord

transmits impulse from sensory to motor neuron with the CNS

phagocytic neuroglia

transmits impulse out of the brain or spinal cord to effectors (muscles or glands)

myelin-forming neuroglia in brain and spinal cord

transmits impulse into brain or spinal cord from receptors
