Joint Receptors Flashcards
Where are Free Nerve Endings found?
Joint capsule
Ligaments
Synovium
Fat Pads
What are free nerve endings sensitive to?
One type: Non-noxious mechanical stress
Other type: Noxious mechanical stress or biomechanics stimuli
How are free nerve endings distributed in the body?
All Joints
Where are Golgi Ligament Endings found?
Ligaments
Adjacent to ligaments’ bony attachments
What are Golgi Ligament Endings sensitive to?
Tension or stretch on ligaments
How are Golgi Ligament Endings distributed in the body?
Majority of joints
Where are Golgi-Mazzoni Corpuscles found?
Joint capsule
How are Golgi-Mazzoni Corpuscles distributed in the body?
Knee Joint, joint capsule
What are Golgi-Mazzoni Corpuscles sensitive to?
Compression of joint capsule
Where are Pacinian Corpuscles found?
Fibrous layer of joint capsule
What are Pacinian Corpuscles sensitive to?
High frequency vibration, acceleration, and high velocity changes in joint position
How are Pacinian Corpuscles distributed in the body?
All joints
Where are Ruffini Endings found?
Fibrous layer of joint capsule
What are Ruffini Endings sensitive to?
Stretching of joint capsule; amplitude and velocity of joint position
How are Ruffini Endings distributed in the body?
Greater density in proximal joints, particularly in capsular regions
