association motor area contain what are?
The association motor area, also known as the supplementary motor area (SMA) or the premotor cortex, contains brain regions that are involved in the planning and coordination of movements. It is responsible for the initiation of complex movements, coordination of different body parts during movement, and the preparation and anticipation of actions. Additionally, the association motor area is involved in motor learning and the integration of sensory information with motor commands.
The association motor area, also known as the premotor cortex, is a region of the brain involved in planning and coordinating voluntary movements. It is located in the frontal lobe, just in front of the primary motor cortex. The specific functions of the association motor area include:
1. Voluntary motor planning: This area helps in planning and organizing complex movements, such as reaching, grasping, and manipulating objects. It integrates sensory information from multiple areas of the brain to determine the appropriate motor responses.
2. Sequencing and coordinating movements: The association motor area is responsible for coordinating and sequencing different muscle groups involved in complex movements. It ensures that the timing and sequence of muscle contractions are coordinated for smooth and efficient movements.
3. Motor learning and memory: This area is involved in learning and storing motor skills and movements in memory. It helps in acquiring new motor skills through practice and repetition.
It's important to note that the association motor area works in conjunction with other motor areas, such as the primary motor cortex and the supplementary motor area, for the execution of voluntary movements. These areas form a complex network involved in motor control and coordination.
The motor area, also known as the primary motor cortex, is responsible for planning, executing, and controlling voluntary movements in the body. It is located in the frontal lobe of the brain, specifically in the precentral gyrus.
The association motor areas that are closely related and work together with the primary motor cortex include:
1. Premotor cortex: This region is involved in planning and coordinating complex movements. It receives input from other cortical areas, sensory information, and instructions from higher brain regions.
2. Supplementary motor area (SMA): The SMA plays a role in the initiation and coordination of complex movements, especially those involving both sides of the body. It helps to plan and execute sequences of movements and is also involved in motor learning.
3. Pre-supplementary motor area (pre-SMA): This region is involved in the planning and initiation of movements, particularly those requiring cognitive control or response inhibition.
4. Posterior parietal cortex: This area integrates sensory information with motor planning and execution, aiding in the coordination of movements with spatial awareness and sensory feedback.
These association motor areas work in conjunction with the primary motor cortex to generate and control voluntary movements.
