PARASYMPATHETIC SYSTEM

Question 1

PARASYMPH system

Intro

Answer 1

• Rest&digest/feed &breed

- Part of ANS
= Autonomic Nervoussystem
- ANS= Afferent and Effernt Fibers  
- ANS=
1. PARASYMPATHETIC
—> «rest and digest»/ Craniosacral
2. SYMPATHETIC
—> «Fight or flight» /Thoracolumbar

Question 2

PARASYMPHATHETiC Nervous System

STRUCTURE

Answer 2

• Ø bodies of parasymph pre.ganglionic neurons

—> in Nuclei of certain Cranial Nerves in brainstem 
III: N. OCULOMOTORIUS 
VII: N. FACIALIS
IX: N. GLOSSOPHARYNGEUS 
X: N. VAGUS

(craniospinal system = //symph=Thoracolumbar Lumbar system

—> in Sacral Spinal cord
- Parasympharetetic Nuclei: Situated near targeh organ// symph close to CNS

Question 3

PARASYMPATHETIC system

Activity and Function

Answer 3

ACTIViTY: more specific - and discrete than symph system

FUNCTION:
1. Controlls Digestion
2. Waste Elimination
—> Homeostasis

3. Parasymph stimulation
   —> Bradycardia Hypotension
