2

What is the reflex pathway

Stimulus --> response --> afferent neurone from Periphery to CNS --> synapse --> efferent neurone from CNS to periphery --> effector --> response

3

What are stretch reflexes

Simple
Mono-synaptic
Knee or jaw jerk reflexes

4

What is the reflex latecy

Time from the stimulus to effect

5

Resist gravity
Maintain posture
Stabilise jaw during vigour movement of the head

6

Why is the spa jaw jerk test

To clinically test the integrity of the trigeminal nerve

7

What are protective reflexes

Poly synaptic
Response to noxious stimulus

8

What is the stumuli for jaw opening reflexes

Intra-oral mechanical or noxious
Extra oral noxious

9

What are the receptors of the jaw opening reflex

Mechanoreceptors
Noicoreceptors

10

What are the responses to the jaw opening reflexes

Inactivation of jaw closers
Inhibitory jaw reflexes

11

What is a reflex

Predictable response to a given stumulus which is rapid and under autonomic control
