(Print)
functional unit of skeletal muscle
neurotransmitter for skeletal muscles
one neuron and all the skeletal muscle fibers it stimulates
brain & spinal cord
connective tissues covers each muscle fiber
where the nucleus is
glia: barrier btw capillaries and neurons
voluntary/skeletal muscles
involuntary
glia: dispose of debris
afferent
stores calcium
glia: helps circulate CSF
conducts impulse away from the cell body
striated and voluntary
efferent
gaps in myelin sheath
nerve glue
processes & interprets information
gap between neurons
bring messages toward the cell body
fatty material that covers the axon
cranial & spinal nerves
thin filaments
striated and involuntary
thick filaments
glia: produces myelin
connective tissue covers each fascicle
visceral, nonstriated and involuntary
