M3 | Descending control – Medial system

Descending motor pathways consist of medial and lateral systems. After a brief overview, this module focuses on major components of the medial system of descending motor pathways.

Learning Objectives

After completing this module, you will be able to:

  1. Articulate the anatomical and functional organization of motor neuronal pools in the spinal cord.
  2. Explain the principles of organization of descending motor pathways.
  3. Compare and contrast medial and lateral descending motor systems in terms of sources of origin, spinal projections and terminations, and behavioral deficits following lesions.
  4. Explain structure and function of the semicircular canals and otolith receptors.
  5. Describe the role of the vestibular system in control of posture, balance, and eye movements.
  6. Summarize structure and function of circuitry involved in control of locomotion.
  7. Summarize structure and function of circuitry involved in control of eye movements.
