Flashcards in Autonomic Nervous System Deck (28):
1

What are the constituents of the Autonomic Nervous System?

sympathetic, parasympathetic and enteric nervous system

2

Post-ganglionic fibres are myelinated or unmyelinated?

all unmyelinated

3

Sympathetic Nervous system starts at the level of the

thoracolumbar region

4

the ganglia of the Sympathetic Nervous system are ----------- to the CNS and have shorter ------------ neurons

Closer
Preganglionic

5

Main Neurotransmitter of the Sympathetic Nervous system

NA, some ACh (sweat glands)

6

Preganglionic neuron of both Sympathetic and Parasympathetic Nervous system is in...

Intermediolateral Cell Column

7

The ganglion of the Sympathetic Nervous system is for

integration and coordination of control

8

2 Types ganglia in the Sympathetic Nervous system are and they are in charge of

PREvertebral --> Vascular tissue
PARAvertebral ---> Non vascular smooth muscle

9

1 Preganglionic Neuron : Many Postgangionic Neuron

Divergence

10

Many Preganglionic Neuron : 1 Postgangionic Neuron

Convergence

11

Hormonal integration in the Sympathetic Nervous system is via the action of (1) released by the (2)

1 Adrenaline
2 Adrenal Glands

12

Parasympathetic Nervous System is the ------ origin

Craniosacral

13

In the Parasympathetic Nervous System the ganglia lies --------- the organ and thus has short ------ganglionic fibres

Close or within the organ
postganglionic

14

Neurotransmitter of the Parasympathetic Nervous System

ACh

15

Most important nuclei of the cranial origin of the Parasympathetic Nervous System

1 Edinger - Westphal
2 Salivatory Nuclei
3 Dorsal Motor & Nucleus Ambiguus

16

in the intermediolateral cell column the Parasympathetic Nervous System preganglionic neuron is located in relation to the Sympathetic

More medial

17

The Parasympathetic Nervous System also had hormonal integration T/F

F

18

There is a larger ratio of pre:post ganglionic neuron in the sympathetic nervous system when compared to the paresympathetic T/F

T

19

Where is the site of coordination of afferent info for the Autonomic Nervous System

NTS

20

Where is the site of coordination of autonomic output for the Autonomic Nervous System

The Hypothalamus (sp. paraventricular nucleus)

21

What type of information does the hypothalamus receives?

Special Sensory
Sensory from intrinsic structures
Hormones
Higher Cortical/Limbic System

22

The hypothalamus compares info to a specific set point T/F

T

23

Example of cellular antagonism of the systems

hart and lung

24

Example of functional antagonism of the systems

pupil and bladder (different targets)

25

most autonomic reflexes require the brain T/F

T

26

in the Autonomic Nervous System there is a visible junction between the nerves and the target T/F

F there is more than 1 transmitter site and the receptor can be away from the synapse

27

Pelvic Ganglia is just parasympathetic nerves T/F

F, it contains both

28

Pelvic Ganglia is has both divergence and convergence as it is a site of coordination T/F

F, only a relay station. there is little integration
