Motor Neuron Flashcards

Upper Motor Neuron Cell Body Location

  • The cell body of the upper motor neuron is located in the primary motor cortex.
  • Specifically, it is found in the precentral gyrus.

Synapse and Lower Motor Neurons

  • The upper motor neuron extends down and synapses on the lower motor neurons.
  • The cell body of the lower motor neuron resides in the spinal cord.

Location within the Spinal Cord

  • The discussion pertains to motor neurons.
  • The location of a motor neuron cell body is being identified.
  • Ventral refers to the front of the spinal cord.

Ventral Horn

  • Cell bodies are located in "horns," not "columns."
  • The cell body is situated in the ventral horn of the spinal cord.
  • The motor neuron then exits from this location.
