Which type of descending motor pathway excites antigravity muscles in order to exert control over postural changes necessary to compensate for tilts and movements of the body.?
A)vestibulospinal tract
B)corticospinal tract
C)corticobulbar tract
D)spinothalamic tract
E)gracile fasciculus

Quizplus · Accepted Answer

The vestibulospinal tract is the descending motor pathway that excites antigravity muscles and plays a crucial role in maintaining balance and posture. It receives information from the vestibular system about tilts and movements of the body and sends signals to the motor neurons in the spinal cord to adjust the muscle tone and control postural changes. The other options listed do not directly control postural changes or excite antigravity muscles.
