Document Summary
Lecture 31: autonomic nervous system: describe, in broad terms, the roles of the sympathetic and parasympathetic divisions of the ans, heart rate. Temperature regulation: autonomic motor neurons two motor axons in series project from lateral horn to periphery. Control of most autonomic targets originates in the brain. The hypothalamus plays a key role in coordinating autonomic responses. Lauren hunt: describe the anatomical differences in the organization of the sympathetic and parasympathetic divisions of the ans. The sympathetic and parasympathetic divisions of ans differ with respect to: In the sympathetic division preganglionic neuron cell bodies originate in the lateral horns t1-t12. Noradrenaline = na" = norepinephrine = ne". Adrenaline = a" = epinephrine = e". Acetylcholine = ach" synapses using ach : cholinergic synapses synapses using na: noradrenergic or adrenergic . Receptors where na acts: either noradrenergic or just adrenergic receptors.
