Study Notes

Brain and Spinal Cord Connection

  • The spinal cord is connected to the brain's base, specifically the brainstem.

Spinal Cord Structure

  • In an adult, the spinal cord begins at the foramen magnum (base of the brain) and ends at the level of the second lumbar vertebra (L2).
  • The spinal cord is longer in children and grows shorter relatively to the vertebral column as they grow.

Nerve Fibers

  • Groups of nerve fibers going towards the brain are called sensory or ascending tracts.
  • Groups of nerve fibers coming from the brain are called motor or descending tracts.

Spinal Cord Development

  • In a growing child, the spinal cord ends at a lower level, around the level of the third or fourth lumbar vertebra (L3-L4).

Spinal Cord Function

  • The primary function of the spinal cord is to transmit messages between the brain and the rest of the body, integrating sensory information and facilitating motor responses.
