Which one of the following motor tracts originates in the motor cortex of the frontal lobe and is functionally responsible for contralateral movement of the body?
|
|
Anterior Corticospinal Tract
|
|
|
Lateral Corticospinal Tract
|
|
|
Rubrospinal Tract
|
|
|
Lateral Vestibulospinal Tract
|
Explanation:
Detailed explanation-1: -The primary responsibility of the lateral corticospinal tract is to control the voluntary movement of contralateral limbs. [1] The origination of the Lateral corticospinal tract is in the primary motor cortex which lies in the precentral gyrus.
Detailed explanation-2: -The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe. The motor cortex is divided into two main areas, Area 4 and Area 6.
