The major descending motor pathways for movement

Question 1

The lateral pathway structure

Answer 1

the lateral pathway originate in the cortex

composed of 3 tracts- lateral corticospinal, corticobulbar, and rubrospinal tracts

Question 2

the lateral pathway function

Answer 2

controls voluntary independent limb movements

Question 4

lateral corticospinal tract

Answer 4

lateral corticospinal tract= axons of cortical neurons that terminate in the grey matter of the spinal cord which stem from the primary motor cortex, Responsible for control of arms, hands, fingers, legs, toes (Known as trunk movements)

Question 5

corticobulbar tract=

Answer 5

corticobulbar= control movement of the face, neck, tongue, and parts of our eye muscle

Question 6

rubrospinal tract

Answer 6

Rubrospinal= originates in the red nucleus to control movement of forearms and hands.
