Structures & Function of Spinal Cord

  • receives and begins to integrate primary sensory input.
  • contains motor neurons that innervate target structures.
  • contains descending fibers from the cortex or brainstem that modulate the activity of spinal motor and sensory neurons.
  • mediation of spinal reflexes.

A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones).

What is spinal cord?

A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones). The spinal cord and the brain make up the central nervous system (CNS).

What are 3 major functions of the nervous system?

The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.
