NEET PG DENTAL EXAM

Detailed explanation-1: -There are two divisions of the corticospinal tract, the lateral corticospinal tract and the anterior corticospinal tract .

Detailed explanation-2: -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-3: -These tracts all carry motor fibres to the spinal cord that allow for unconscious, reflexive or responsive movement of muscles to control balance, locomotion, posture and tone. There are four tracts[2].

Detailed explanation-4: -The corticospinal tract controls primary motor activity for the somatic motor system from the neck to the feet. It is the major spinal pathway involved in voluntary movements. The tract begins in the primary motor cortex, where the soma of pyramidal neurons are located within cortical layer V.
