iv. Lateral corticospinal tract
b. 1 and 3
c. 2 and 4

e. None of the above
Activity
-
Draw a transverse section of the spinal cord through the cervical region. Include:
o *Ventral grey horns
o *Dorsal grey horns
o Central canal
o Grey commissures (anterior and posterior)
o *Lateral white columns
o *Ventral white columns
o *Dorsal white columns
o *Dorsal root
 *Dorsal root ganglia
o *Ventral root
o *Spinal nerve
*Indicate the type of information and the part of the neuron located in these structures. (e.g.
sensory vs. motor, axons vs. soma)
-
Draw a transverse section of the spinal cord through the thoracic region. Include:
o *Ventral grey horns
o *Dorsal grey horns
o *Lateral gray horns
o Central canal
o Grey commissures (anterior and posterior)
o *Lateral white columns
o *Ventral white columns
o *Dorsal white columns
o *Dorsal root
 *Dorsal root ganglia
o *Ventral root
o *Spinal nerve
*Indicate the type of information and the part of the neuron located in these structures. (e.g.
sensory vs. motor, axons vs. soma)
-
Draw the basic pathway of motor information. Include:
o Upper motor neuron
o Lower motor neuron
o *Include the structures where the soma of these neurons are located
o Describe flaccid and spastic paralysis
 Destruction of the UMN would lead to __________________, and destruction of
the LMN would lead to __________________________.
-
Draw the basic pathway for sensory information. Include:
o First order neuron
o Second order neuron
o Third order neuron
o *Indicate the structures where the cell bodies of each of these neuron types are housed
