Why are hands large on the motor homunculus model?
Hands are large on the motor homunculus model because they represent the large area of the motor cortex dedicated to controlling hand movements. The motor cortex has a somatotopic organization, with different body parts represented based on their level of dexterity and complexity of movements. Hands and fingers have a high concentration of motor neurons and require precise control, hence the larger representation in the motor homunculus model.
What central lobe of the brain is the primary motor cortex?
The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.
Where are the sensory and motor cortex located?
The motor cortex is in the frontal lobe of the brain whilst the sensory cortex is in the parietal lobe. Another main difference is that the motor cortex controls movements of fine and gross motor skills whereas the sensory cortex controls feelings of touch and sensation.
Where are Mirror neurons found in the brain?
Mirror neurons are found in various regions of the brain, including the premotor cortex, supplementary motor area, and inferior parietal lobule. These areas are involved in motor planning and execution, as well as in understanding the actions and intentions of others.
What sulcus separates the primary motor cortex fron the primary sensory cortex?
The central sulcus is a fold in the cerebral cortex of brains in vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando.The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.
What part of the body is associated with the greatest amount of brain tissue in the motor cortex?
The face is the body part that is associated with the greatest amount of brain tissue in the motor cortex. The motor cortex is the part of the brain that does the controlling and execution of movements.

Where is Motor cortex found?
The motor cortex is found in the brain.
What does the motor cortex do?
Motor cortex is a region found in the cerebral cortex of the brain. It main function is to plan, control, and execute voluntary motor processes.
What represent the motor areas of the cortex?
Primary motor cortex, premotor cortex, Broca's area and frontal eye field
What central lobe of the brain is the primary motor cortex?
The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.
What best represents the motor areas of the cortex?
The motor areas of the cortex are mainly represented by the primary motor cortex, located in the frontal lobe of the brain. This region is responsible for planning, executing, and controlling voluntary movements in the body. Additionally, the premotor cortex and supplementary motor area also play important roles in motor coordination and movement planning.
What are the functions of motor cortex?
Pre central gyrus has got the motor cortex. Through this area you get the initiation of final motor pathway.
Where is located the primary motor cortex?
The primary motor cortex is located in the precentral gyrus of the the frontal lobe of the cerebrum.
The motor cortex is located in the?
Its located in the cortex of the brain, the highest part of the brain. The left side of the cortex controls the right side of the body and vice versa. The actual motor parts are in known as the precentral gyrus. ----just in front of the central sulcus
What is the function of the Primary Motor Cortex?
The primary motor cortex controls voluntary movements. Damage to the primary cortex would impact the ability to control voluntary movement.
Where is the somatic motor cortex?
The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.
