Document Summary

Structural components: sensory receptors: respond to stimulus and initiate an action potential in sensory neurons, nerves & ganglia: packaging of axons, motor endings: innervate end structures (cells) Complex specialized cell: type of stimuli they detect, location in body. Allow you to respond to light touch. Root hair plexus: responds to movement of hair follicle. Proprioceptors nerve ending wrapped around muscle fibers, tendons, or joint capsules that respond to stretch. Cerebellum uses information to determine where our body parts are in space: thermoreceptors: temperature. Respond to light (found in retina of eye: nociceptors: pain. Free nerve endings that respond to mechanical thermal or chemical stimuli. Pain is an emotional way our brain interprets stimulus. Motor unit 1 somatic motor neuron and all the muscle fibers it innervates. Neuromuscular junction location where axon terminal communicates w/ skeletal muscle fiber. Neurotransmitter released at neuromuscular junction with skeletal muscle cell. Acetylcholine (ach) released and binds with skeletal muscle creating a reaction.
