Skin

Question 2

Answer 2

Ability to consciously sense & interpret position & movements of body parts

Mainly processed in cerebral cortex

Question 3

What is unconscious proprioception

Answer 3

Involved in maintaining posture, balance & coordinating movements without needing active conscious attention

Processed in spinal cord & lower brain regions

Question 4

What is the spinocerebellar tract

Answer 4

Ascending pathways that relay proprioceptive information from body to cerebellum

Responsible for providing feedback about position, movement & tension of muscles/tendons to cerebellum

Question 5

What is the cuneate/gracile tract

Answer 5

information related to fine touch, vibration & conscious proprioception to brain

Tracts primarily carry information from upper (cuneate) & lower (gracile) extremities
