afferent correct answers sensory, cell bodies in dorsal root ganglion efferent correct answers motor, cell bodies in anterior horn interneuron correct answers within spinal cord, connects sensory to motor neuron somatic afferent correct answers touch, pain, temp, pressure, proprioception, via dorsal root visceral afferent correct answers organs, via rami communicans, via dorsal root somatic efferent correct answers innervate skeletal muscles, ventral horn autonomic efferent correct answers involuntary motor, sympathetic (lateral thoracic horn) parasympathetic (lateral sacral horn) referred pain correct answers visceral afferent meets somatic afferent in posterior horn dorsal column-medial lemniscal correct answers ascending tract, fine touch/pressure, vibration, skin movement, proprioception, crosses at medulla faniculus gracilis correct answers dorsal column-medial lemniscus, lower limbs dorsal column-medial lemniscal pathway correct answers limb to spinal cord to medulla (crosses) to pons to cerebellum to midbrain to cerebrum anterolateral spinothalamic correct answers ascending tract, pain, itch, tickle, crude touch/pressure, temp, sexual sensations, crosses at spinal cord level anterolateral spinothalamic pathway correct answers limb to spinal cord (crosses) to medulla to pons to midbrain to thalamus to cerebrum anterior corticospinal tract correct answers descending tract, voluntary motor, proximal muscles, internal capsule to cerebral peduncle (crosses at spinal cord level) lateral corticospinal tract correct answers descending tract, fine movement of limbs, internal capsule to cerebral peduncle (crosses at pyramids) somatic innervation correct answers voluntary system, motor neuron leaves ventral root, synapses on motor end plate autonomic innervation correct answers involuntary motor system, 2 neurons to reach effector organ (pre/post-ganglionic), counterbalance
