Pyramidal cell axons project through corticospinal tracts and
synapse at
a. motor nuclei of cranial nerves.
b. motor neurons in the anterior horns of the spinal
cord.
c. motor neurons in the posterior horns of the spinal
cord.
d. motor neurons in the lateral horns of the spinal
cord.
Pyramidal neurons have soma(body cell) that is of rounded pyramid shape. Hence they are called pyramidal neurons. The characteristic features of pyramidal neurons is the presence of single axon, large apical dendrite along with numerous basal dendrites.
It is a type of multipolar neurons that are found in the cerebral cortex of all mammals. They can also be found in the subcortical regions of amygdala and hippocampus.
The correct answer is option b.
Pyramidal cells axons synapse at motor neurons in the anterior horns of the spinal cord.
Explanation:
The pyramidal cells axon pass through the corticospinal tracts and they join with the motor neurons. The motor neuron are present in the anterior (ventral) horns of the grey matter.
