Pain impulses originating at nociceptors are transmitted to the CNS via - ANSWER Afferent fibers ________ receptors are useful in situations where it is important to signal a change in stimulus intensity rather than relay status quo information - ANSWER Tonic Each __________ sensory neuron responds to stimulus information only within a circumscribed region of the skin surface surrounding it - ANSWER Tactile Binding a chemical messenger by specific protein-receptor sites on an afferent n...

Abducens (VI) - motor origin: pons term: lateral rectus -rotates eye laterally Accommodation - looking at an object up close -eyes converge ex) crossing -pupils constrict -lens changes: more curved (up close) Adaption of sensory receptors - most sensory receptors adapt, become less sensitive during prolonged time; Nociceptors and most proprioreceptors do not adapt Adrenergic neurons - secrete NE sympathetic postganglionic fibers 1. alpha adrenergenic: constrict blood vessels and dila...
