Answer 1

Peripheral

Question 2

Autonomic nervous system connects the ________ and the ___________ with internal organs and regulates internal _____ _____

Answer 2

It connects the brainstem and the spinal cord with internal organs

and regulates internal body procesesses

Question 3

Autonomic nervous system controls?

Answer 3

• It controls BP, HH and RR
• Body temp.
• Digestion and metabolism
• Production of body fluids (saliva, sweat and tears)
• Urination and defecation
• Sexual response
• Certain reflex actions (coughing, swallowing, vomiting)

Question 4

Integrating centres are located in the:

Answer 4

• Spinal cord
• Medulla oblongata
• Hypothalamus (principle coordinating centre for ANS)

Question 5

ANS consist of _______ neurons

These neurons control what?

Answer 5

Motor

Smooth muscle, cardiac muscle and gland control!

Question 6

Additionally, ANS also monitors with _______ neurons

ANS monitors ________ and _________

->info to central nervous system

Answer 6

Sensory

Visceral organs and blood vessels

Question 7

Autonomic nervous system

Answer 7

Systema nervosum autonomicum

Question 8

ANS has two parts

Answer 8

1. Sympathetic part (“fight or flight”)

2. Parasympathetic part (“rest and digest”)

Question 9

Most sympathetic ganglia are found

Answer 9

Outside the spinal cord; on both sides

Question 10

Most parasympathetic ganglia are found

Answer 10

Near OR in the organs they connect with

Question 11

Communication with ANS needs two neurotransmitters. What are these neurotransmitters, what kind of effect they have and which fibers are in charge?

Answer 11

• Cholinergic fibers -> Secrete acetylcholine -> has inhibiting effect
• Adrenergic fibers -> Secrete norepinephrine -> has stimulating effect

Question 12

All pregangliotic fibers release __________

Answer 12

Acetylcholine

Composed of two ____________ neurons:

 1st) \_\_\_\_ganglionic
 2nd) \_\_\_\_\_ganglionic

Answer 14

The Efferent pathway:
- From the CNS to visceral organ

Composed of two multipolar neurons

  1st) PREganglionic
  2nd) POSTganglionic

Question 15

Preganglionic:
Cell body in the ____ OR _____
Postganglionic
Located in the ________ ganglion (= _____ of ____
cells). Connects the _______ cell with the autonomic
ganglia in the __________ nervous system
The fibers of these neurons are _______

Answer 15

Pre: Cell body in the BRAIN or SPINAL CORD

Post: Located in AUTONOMIC ganglion (=CLUSTER of NERVE cells). Connects the EFFECTOR cell with the autonomic ganglia in the PERIPHERAL nervous system
