KIN 190 Study Guide - Adrenergic Receptor, Brainstem, Beta Blocker
Document Summary
You should be able to: describe the anatomy and roles of the autonomic nervous system. Peripheral nerves contain motor/sensory nerves, motor nerves can be somatic/innervate smooth muscle, cardiac muscle and glands, autonomic pathways (synapsing cells along a route) have ganglia outside spinal cord (pre/postganglionic neurons) Unconscious regulation, target tissues stimulated or inhibited, 2 synapses (ganglion/effector), receptor molecules: define autonomic pathway". Synapsing cells along a route: compare the somatic and the automatic nervous systems including generalities and specifics. Somatic: motor neurons innervate skeletal muscles, conscious/unconscious movement, one synapse (at effector), acetylcholine, receptor molecules are nicotinic. Autonomic: motor neurons innervate smooth/cardiac muscles, glands, pathways include ganglia outside spinal cord, pre/post ganglionic neurons, unconscious regulation, target tissues stimulated/inhibited, 2 synapses (one at ganglion/one at effector), acetylcholine from preganglionic neurons and ach. Receptor molecules vary w/ synapse and neurotransmitter (with chain ganglia: describe the roles of the sympathetic and parasympathetic nervous system and compare/contrast the two.
