Question

What are the primary 6 descending (efferent) tracts of the spinal cord?

Answer 1

The primary 6 descending (efferent) tracts of the spinal cord are: corticospinal, vestibulospinal, reticulospinal, rubrospinal, tectospinal, and medial (pontine) reticulospinal.

Step-by-step explanation:

The primary 6 descending (efferent) tracts of the spinal cord are:

1. Corticospinal tract: Controls skeletal muscle movements
2. Vestibulospinal tract: Regulates balance and muscle tone
3. Reticulospinal tract: Modulates motor functions and autonomic responses
4. Rubrospinal tract: Helps regulate muscle tone and control limb movements
5. Tectospinal tract: Coordinates head and eye movements in response to visual stimuli
6. Medial (pontine) reticulospinal tract: Influences spinal reflex movements and posture
