Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The lateral columns include ____ that travel from the cerebral cortex to contact spinal motor neurons.
A
ganglia
B
axons
C
soma
D
dendrites
Explanation: 

Detailed explanation-1: -The lateral columns include axons that travel from the cerebral cortex to contact spinal motor neurons. These pathways are also referred to as the cortico-spinal tracts.

Detailed explanation-2: -ie all the neurones within the descending motor system are classed as upper motor neurones. Their cell bodies are found in the cerebral cortex or the brain stem, with their axons remaining within the CNS[1].

Detailed explanation-3: -The corticospinal tract, AKA, the pyramidal tract, is the major neuronal pathway providing voluntary motor function. This tract connects the cortex to the spinal cord to enable movement of the distal extremities.

Detailed explanation-4: -Located in the frontal lobe are the motor cortex and the Broca area. The motor cortex allows for the precise voluntary movements of our skeletal muscles, while the Broca area controls motor functions responsible for producing language.
