Conscious Proprioception Pathway

Question 1

What is proprioception?

Answer 1

Position and movement sense

Monitors position of muscle, tendon and joints which serves to guide movement

Two types:
Conscious
Unconscious

Question 2

What does a loss of proprioception?

Answer 2

Sensory ataxia

• Uncoordinated movement
• Cerebrum and cerebrum lack sensory feedback about body position and rate of movement
• Worsens when eyes closed to due to inability to compensate with vision

Question 3

Proprioception receptors?

Answer 3

Joint receptors
Muscle spindles
-Annulosprial endings
-Flower Spray endings
-Golgi Tendon Organs

Question 4

Proprioception afferent axons?

Answer 4

Type Ia
Type Ib
Type II (same size as Beta)

Question 5

Conscious proprioception pathways are?

Answer 5

Spinal cord
-Dorsal column

Brainstem
-Medial lemniscus

Question 6

Dorsal column-medial lemniscus system is?

Answer 6

Same pathway as light touch

• Information travels in dorsal column in the spinal cord
• In the brainstem, the information travels up the medial lemniscus
