Summary Introduction
To review:
Match the term corticospinal system with the most closely related description given below:
Second order
Pain, temperature, crude touch, pressure
Voluntary control skeletal muscle
Subconscious control of distal limb musculature
Afferent
Information about “what,” “where,” and “when”
Unconscious proprioception

Position change noise-related
Introduction:
The corticospinal system includes corticospinal tracts, such as the corticobulbar, anterior, and lateral corticospinal tracts. These corticospinal tracts (pyramidal tract) form the descending tracts of the spinal cord that control motor signals.
