Identify each of the following spinal tracts-the gracile fasciculus and the lateral corticospinal, lateral reticulospinal, and spinothalamic tracts-with respect to whether it is ascending or descending; its origin and destination; and what sensory or motor purposes it serves.

Which extrapyramidal tract incorporates equilibrium sensations with motor commands to aid in posture and movement? a. tectospinal tract b. vestibulospinal tract c. reticulospinal tract d. corticospinal tract
Spinal Nerve Tracts: Neurons carry impulses from the brain to the appropriate spinal nerve, then to the effector by way of motor tracts. There are a number of motor tracts, both voluntary and involuntary. The voluntary motor path to skeletal muscles is called the pyramidal system (named for the pyramidal cells of the motor cortex). One of the most common pyramidal system tracts, and the one you are responsible for knowing, is the corticospinal tract. The name describes the path from the motor cortex to the spinal cord and nerves. Neurons that carry impulses from receptors within the body, up the spinal cord, to the brain do so by means of sensory pathways. There are several sensory pathways depending on the type of stimulus involved, region of the spinal cord that the neurons travel, or the ultimate destination of the path. You will be learning a general sensory pathway that incorporates a couple of these specific tracts.
