Function: transmission of impulses from motor neuron to effector cell
Location: skeletal muscle fibers
Location: secretory cells of many glands
Function: nerve impulse initiation in response to: external stimuli (temperature, touch, smell, sound, vision) - exteroceptors; stimuli from within the body (filling or stretch of the alimentary canal, bladder, blood vessels) - enteroceptors; sensation of body position and muscle tone and movement - proprioceptors.
Location: epithelia, connective tissue
Location: skin and joint capsules (end bulb of Krause, Ruffini corpuscles, Meissner's corpuscles, Pacinian corpuscles); skeletal muscle (neuromuscular spindles); muscle-tendon junctions (Golgi tendon organ)
Function: transmission of impulses from one neuron to the next in the chain.
Location: between axons and dendrites.
Location: between axons and the cell body.
Location: between axons and axons.
Location: between dendrites and dendrites.
Presynaptic knob (component)
Function: the end of neuron process from which neurotransmitter is released.
Function: 20-30 nm space that neurotransmitter must cross.
Postsynaptic membrane (component)
Function: receptor sites on the plasma membrane with which the transmitter interacts
