The precentral gyrus is associated with waving, throwing, and grasping. because of this, it is also known as The primary motor cortex.
The precentral gyrus is a prominent gyrus on the surface of the posterior frontal lobe of the brain. The precentral gyrus is the anatomical location of the primary motor cortex, which is responsible for controlling voluntary motor movement on the body's contralateral side.
The precentral gyrus is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch. The precentral gyrus, also known as the primary motor cortex, is a very important structure involved in executing voluntary motor movements.

The precentral gyrus is associated with waving, throwing, and grasping. because of this, it is also known as The "Primary Motor Cortex".
The primary motor cortex (Brodmann's area 4) is a brain region located in the dorsal portion of the human frontal lobe. It is a major area of the motor system and coordinates with other motor areas, including the premotor cortex, supplementary motor cortex, posterior parietal cortex, and several subcortical brain regions to plan and execute movements. The primary motor cortex is anatomically defined as a region of the cortex that contains large neurons known as Betts cells. Betts cells, along with other cortical neurons, send long axons to the spinal cord, synapsing with interneuron circuits in the spinal cord and synapsing directly with alpha motor neurons in the spinal cord that connects to muscles.
The motor cortex controls motor behavior by generating movement-specific signals and transmitting them to muscles through spinal cord circuits and motor neurons. Precise and well-coordinated muscle activation patterns are required to perform precise movements.
