What does the EFFERENT control?

Motor

2

Control of Ventilation:

what does the AFFERENT control?

Sensory

3

Control of Ventilation:

on the diagram (for visual prupose only) mark the efferent and afferent side

 

4

Control of Ventilation:

what part of the brain is responsible for ventialtion

brainstem

(pons and medulla)

5

Control of Ventilation:

what type of muscle is teh diaphram?

Skeletal

6

Control of Ventilation:

what is the Major Muscle of inspiration?

Diaphram

7

Control of Ventilation:

the diaphram controlls what % of TV

75%

8

Control of Ventilation:

the diaphram is made up of what type of receptors

Nicotinic ACh

9

Control of Ventilation:

what cervical nerves are responsible for the Phrenic nerve?

C3,4,5

10

Control of Ventilation:

which Ohrenic nerve carries the majority of the Phrenic nerve

C4

11

Control of Ventilation:

what are the 3 main Motor (effernt) nerves of ventilation?

Phrenic n.

External intercostal n.

Internal intercostal n.

12

Control of Ventilation:

what type of Nerves are the 3 major motor (efferent) nerves of ventilation?

A-alpha motor neurons

13

Control of Ventilation:

Picture of the 3 main motor (efferent) nerves of ventilation

 

14

Control of Ventilation:

what are the 3 motor (efferent) muscles that the Phrenic, external intercostal, and internal intercostal nerves innervate?

external intercostal

internal intercostal

diaphram

15

Control of Ventilation:

What Efferent (motor) nerve innervates the Diaphram?

Phrenic n.

16

Control of Ventilation:

what efferent (motor) nerve innervates the External intercostal muscle?

External Intercostal n. 

17

Control of Ventilation:

what Efferent (motor) n. innervates the internal Intercostal muscle

internal intercostal n.

18

Control of Ventilation:

Does the External intercostal muscle control Inspiration or expiration?

inspiration

19

Control of Ventilation:

does the diaphram control inspiration or expiration

inspiration

20

Control of Ventilation:

dose the Internal intercostal muscle control inspiration or expiration?

both (but more expiration)

21

Control of Ventilation:

what controls expiration?

mainly passive

but internal intercostals help

22

Control of Ventilation:

what are the 2 Afferent (sensory) nerves of respiratorion?

Glossopharyngeal n. (hering's n., Sinus n.)

Vagus n.

23

Control of Ventilation:

what does the afferent (sensory) Glossopharyngeal n. (IX) origonate? and end?

 

peripheral chemoreceptors of carotid

end at DRG

 

24

Control of Ventilation:

where does the Afferent (sensory) vagus nerve origonate? and end

the Alveolus 

peripheral chemore ceptors in aortic arch

ends w/ DRG

25

Control of Ventilation:

what do peripheral chemoreceptors detect?

CO2

O2

H+

26

Control of Ventilation:

where are the peripheral chemoreceptors located

Carotid body and aoric arch

(both innervated via Vagus (X) )

27

Control of Ventilation:

what are the 4 centers that control ventilation

  • PnC- Pneumotaxic Center (now called the PRG- Pontine respiratory group)
  • ApC- Apneustic center (secondary resp center in pons)
  • DRG- Dorsal respiratory group
  • VRG- Ventral respiratory group

 

We don;t really give a shit about the ApC

28

Control of Ventilation:

what 2 centers are locataed in the Pons

PnC (PRG)

ApC

29

Control of Ventilation:

What 2 centers are in the medulla?

DRG

VRG

30

Control of Ventilation:
