Q

Lumbar splanchinic nerves contribute to ___ plexues

A

inferior mesternic

superior hypogastic

17
Q

Hypogastic nerves carry ___ into plevis and form __ plexus

A

Carry preganglionic sympathetics

Form the majority of the inferior hypogastric plexus

18
Q

General functions of sympathethic vs parasympathetic postganglionic fibers

A

Sympathetic: dilation of blood vessels, increase sweat, close sphincters

Parasympathethic do the opposite

19
Q

Difference between cardiopulmonary splanchnic nerve vs. abdominopelvic splanchnic nerves

A

Postganglionic fibers in cardiopulmonary splanchnic

Preganglionic fibers in abdominopelvic

20
Q

Least thoracic splanchinic nerves carry preganglionic sympathethics from

A

T12

21
Q

Vagus nerve carries

A

perganglionic parasympathethics

22
Q

Function of preganglionic parasympatehthics from the vagus nerve

A

Decreases heart rate

Decreases contractile force

Constriction of coronary artreries

Consrict bronchioles

Increase peristalsis

23
Q

Function of postganglionic sympathethics from pulmonary splanchnic nerves

A

Dilate bronchioles

Inhibit glandular ssecretion
