Question

fill in the blank question

the ____ tracts of the spinal cord carry sensory information to the brain, while ____ tracts carry motor impulses from the brain to the periphery

need help? review these concept resources.

Explanation:

In the spinal cord, ascending tracts are responsible for transmitting sensory information (like touch, pain, temperature, etc.) from the body to the brain. Descending tracts, on the other hand, carry motor commands (instructions for muscle movement, coordination, etc.) from the brain down to the peripheral parts of the body (like muscles, glands). This is a fundamental concept in neuroanatomy, specifically related to the functional organization of the spinal cord's white matter tracts.

Answer:

The $\boldsymbol{\text{ascending}}$ tracts of the spinal cord carry sensory information to the brain, while $\boldsymbol{\text{descending}}$ tracts carry motor impulses from the brain to the periphery.
