Answer 1

voluntary, skeletal muscles

Question 2

autonomic nervous system

Answer 2

involuntary or visceral
ex: smooth m, heart, glands

Question 3

sympathetic

Answer 3

key role in body response to stress
stimulate cardiovascular and respiratory
diminish digestive, urinary and repro functions when stressed

Question 4

sympathetic trunk

Answer 4

chain of ganglion outside vertebral canal

Question 5

communicating branches

Answer 5

connect spinal n and sympathetic trunk

Question 6

GVE sympathetic to peripheral smooth mm and glands

Answer 6

lateral horn-> ventral root->communicating branch-> ganglion in sympathetic trunk (SYNAPSE)->communicating branch-> ventral and dorsal branches (post-ganglionic)

Question 7

GVE sympathetic to internal smooth mm, glands and heart

Answer 7

lateral horn-> ventral root-> communicating branch-> sympathetic trunk-> splanchnic nerves->visceral ganglion (SYNAPSE)->target organ (post-ganglionic)

Question 8

GVE sympathetic to head sm and glands

Answer 8

lateral horn-> ventral root-> communicating branch->cervicothoracic ganglion-> middle cervical ganglion->sympathetic trunk-> cranial cervical ganglion (SYNAPSE)-> to head

Question 9

visceral afferent neuron pathway

Answer 9

take sensory info to spinal nerve, then spinal ganglion, then dorsal root to dorsal horn
