What are the ascending and descending tracts of the spinal cord?

The ascending tracts carry sensory information from the body, like pain, for example, up the spinal cord to the brain. Descending tracts carry motor information, like instructions to move the arm, from the brain down the spinal cord to the body.

What are the ascending and descending tracts of the spinal cord?

The ascending tracts carry sensory information from the body, like pain, for example, up the spinal cord to the brain. Descending tracts carry motor information, like instructions to move the arm, from the brain down the spinal cord to the body.

What are the descending spinal tracts?

Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor tracts, due to their involvement in movement coordination. These tracts can be classified by their structural arrangement, into lateral and medial tracts.

What are the ascending tracts?

As the name suggests, the ascending tracts of the spinal cord ascend from the spinal cord and connect it to the brain. These tracts are named based on their origin and termination. They are found running along the dorsal, lateral, and ventral columns of the white matter.

What are ascending and descending pathways?

Ascending pathway: A nerve pathway that goes upward from the spinal cord toward the brain carrying sensory information from the body to the brain. In contrast, descending pathways are nerve pathways that go down the spinal cord and allow the brain to control movement of the body below the head.

How many descending spinal tracts are there?

There are four tracts: Reticulospinal. Vestibulospinal. Rubrospinal.

However, the other tactile modalities are transmitted through the ascending tracts of the spinal cord. There are eight known ascending tracts conveying a variety of sensory stimuli that are discussed below.
