Definition

Noun: - The cortical area that influences motor movements: The "motor region" is a specific area of the cerebral cortex in the brain primarily responsible for generating and controlling voluntary muscular movements. It is crucial for planning, executing, and coordinating physical actions.

Usage

The term "motor region" is used in scientific, medical, and anatomical contexts to refer to the part of the brain directly involved in motor control. - It is often discussed in relation to neuroscience, neurology, and psychology. - It is typically modified by adjectives specifying its exact location or function (e.g., primary motor region).

Examples

• Noun:
  • Damage to the primary motor region can result in paralysis or loss of fine motor skills.
  • The study used fMRI to map activity in the motor region when participants performed hand movements.
  • Signals from the motor region travel down the spinal cord to activate muscles.

Advanced Usage

• "Primary motor region" / "Primary motor cortex": The most studied part of the motor cortex, located in the precentral gyrus, where execution of movement is initiated.
  • Neurons in the primary motor region are arranged according to the body parts they control.
• "Supplementary motor region": An area involved in the planning and coordination of complex movements.
  • The supplementary motor region is active even when imagining a movement without physically performing it.

Variants and Related Words

• Motor cortex (n): A more common synonym for the motor region, encompassing both primary and associated motor areas.
  • The motor cortex is divided into several functional zones.
• Precentral gyrus (n): The anatomical landmark for the primary motor region.
• Motor area (n): A general term for any brain area involved in movement control.

Synonyms

• Motor cortex: The region of the cerebral cortex involved in planning, control, and execution of voluntary movements.
• Rolando's area: An older term for the primary motor cortex.

Related Phrases

• Motor function: The ability to use and control muscles and movements, governed by the motor region.
  • The stroke impaired his motor function due to damage in the motor region.
• Motor neuron: A nerve cell that carries signals the central nervous system (ultimately from areas like the motor region) to muscles.
  • Motor neurons relay commands from the motor region to the limbs.
