GradeBuddy is best used as a supplement to your own notes, not as a substitute.-interoreceptors: visceral (gut) sensory, not consciously aware of these stimuli-motor neurons-somatic motor neurons innervate skeletal muscle-visceral motor neurons innervate cardiac muscle, smooth muscle, and glands-anatomy of neurons-cell body: contains nucleus-axon: single long process of cell body-dendrite: tree like multiple processes that radiate from a neuron cell body, act as receptors-synaptic knobs: terminal regions of axon, pass information on-types of neurons-sensory: carry impulses toward the CNS-motor: carry impulses away from the CNS-neuron: a single nerve cell-nerve: bundle of neuron axons in PNS; held together by connective tissue-tract: bundles of neuron axons in CNS-glia-functions-structural: provide framework for neural tissue-protective: act as phagocytes-maintenance: maintain the intercellular environment-types-astrocytes: form blood-brain barrier-epedymal cells: help produce CSF-microglial cells: remove dead and damaged nervous tissue-neuron classification-somatic: voluntary-skin, skeletal muscles, bones, joints, ligaments, tendons-general senses: touch, pain, pressure, hot/cold, vibration, proprioception-special senses: taste, smell, vision, hearing, balance-visceral: involuntary-organs, smooth and cardiac muscle, glands-blood pressure, blood gases, stretch of organs-efferent: motor-effectors: transmits impulse from CNS to somatic or visceral muscle-afferent: sensory-receptors: transmits impulses from somatic of visceral structures to
