Where do motor pathways begin?

What is motor pathway?

a neural pathway that originates in the brain or brainstem and descends down the spinal cord to control the motor neurons. The motor pathways can control posture, reflexes, and muscle tone, as well as the conscious voluntary movements associated with the motor system. a.

Where do the lower motor neuron pathways originate?

The upper motor neurons originate in the cerebral cortex and travel down to the brain stem or spinal cord, while the lower motor neurons begin in the spinal cord and go on to innervate muscles and glands throughout the body.

How many direct motor pathways are there?

There are two vestibulospinal pathways; medial and lateral. They arise from the vestibular nuclei, which receive input from the organs of balance.

What do the ventromedial pathways control?

The lateral pathways are involved in the voluntary movement of the distal musculature. The lateral pathways control the fine movements of arms and fingers. The ventromedial pathways control the posture of the head and neck.

What are the two types of motor activity how are they controlled?

Motor control is divided into two subsets. Gross motor control is the ability of a human to move a large muscle group or segment of the anatomy; the waving of an arm is an example of this type of movement. Fine motor control is the ability to manipulate precise movement, such as handwriting.
