Proprioception

Question 1

Where are proprioception axons found?

Answer 1

Connective tissue of joints (capsules and ligaments etc)

Question 2

What do proprioceptive axons do?

Answer 2

Respond to changes in angle, direction and velocity of movement of a joint. Also prevent excessive flexion, or extension.

Question 3

Are proprioceptive axons fast or slow adapting and low or high threshold?

Answer 3

Mixture of all 4

Question 4

What are the 4 nerve endings involved in proprioception?

Answer 4

Free nerve endings
Golgi type
Paciniform endings
Ruffini endings

Question 5

What do free nerve endings do and where are they found?

Answer 5

Capsule and connective tissue
Most numerous
HT and SA – nociceptive function

Question 6

What do golgi type endings do and where are they found?

Answer 6

Ligaments

HT and SA – protective role

Question 7

What do Paciniform endings do and where are they found?

Answer 7

Periosteum near the articular attachments and the fibrous part of the joint capsule
LT and SA – acceleration detectors

Question 8

What do Ruffini endings do and where are they found?

Answer 8

Joint capsule

LT and SA - static position and speed of movements
