Primary Motor Cortex Anatomy - Brain Structure and Function Explained #3800222 (License: Personal Use)

This anatomical illustration displays the primary motor cortex (Brodmann area 4) in red on both lateral and medial sections of the human cerebrum. The region lies along the precentral gyrus, anterior to the central sulcus, and is organized somatotopically-mapping body parts from toes (medial) to face (lateral). It sends direct corticospinal projections to spinal motor neurons for precise motor execution.

Used in neuroscience education, medical textbooks, and online health resources to explain motor control pathways; targets students, healthcare professionals, and patients seeking to understand stroke-related motor deficits or neurosurgical planning.
