ANATOMY 3300 Study Guide - Midterm Guide: Distal Convoluted Tubule, Arytenoid Cartilage, Ureter
Document Summary
Unit 5 study guide: sns vs. ans. The autonomic nervous system: effector: skeletal muscle, efferent pathway: one neuron system, neurotransmitter and response of the target organ, acetylcholine, excitatory.

Location of cell bodies: preganglionic neurons brain and sacral spinal cord, postganglionic neurons in the ganglia. Difference in parasympathetic innervation to viscera within the abdominopelvic cavity. Unit 5 study guide: presynaptic ventral root > spinal n. > ventral rami > pelvic splanchnic nerve, synapse in intramural ganglia, postsynaptic innervate distal of large intestine, pelvic viscera (urinary bladder, ureters, and reproductive organs) Intramural ganglion ganglia are in or near the wall of the effector organ: sympathetic division of the ans usually speeds up or stimulates all body functions except digestion.
