Lecture 10: Joint receptors and skin research Flashcards
1
Q
Ruffini endings found in joint capsule impact:
A
Joint position, displacement, angular velocity, and intra-articular pressure
2
Q
Pacinian Corpuscles found in joint capsule impact:
A
Acceleration of the joint
3
Q
Golgi endings found in joint ligaments impact:
A
Tension in ligaments at extremes of movement
4
Q
Free endings are found:
A
Throughout connective tissue
5
Q
Function of joint receptors:
A
- Fire only over limited range
- Activated by muscle contractions
- Some only fire with major deformation of capsule/ligament
- Joint infusion (swelling) activates joint receptors and can reflexively inhibit maximal muscle activation
6
Q
Pointed angle matches actual angle when?
A
At the end of range of motion
7
Q
Firing rate of joint receptors could mean:
A
End of movement, or swelling/joint infusion
8
Q
Joint receptors role in proprioception:
A
Monitors end of range of motion
