What is masses of gray matter deep within he cerebrum that help regulate body movement and the muscles of facial expression?
The cerebrum is the part of the brain that interprets input from the senses, controls the movement of skeletal/voluntary muscles, and carries out complex mental processes. the part that recieves sensory messages.it acts as the center of emotion,consciousness,learning and all voluntary movement.it is also the largest part of the brain. protective membrane around the brain
Symptoms of Parkinson's disease include a tremor (a 'pill-rolling' movement of their fingers and head nodding) a forward-bent walking position and shuffling gait. A stiff facial expression and they are slow in carrying out any movements. Tremors, shaking, stiff muscles, slow movement, difficulty walking, and weakness of face muscles.
The brain control of voluntary muscles resides in the cerebral cortex, a part of the cerebrum (modern-most part of the brain [approximately 3/4 of total]). However, no single brain part is responsible for all voluntary muscles. Muscular activity is controlled by various parts of the cerebrum. Location depends upon specific muscles and functions. *There are involuntary muscles and functions that are controlled by the nervous system without direct involvement of the brain at all.
The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight. The cerebrum is the thinking part of the brain and it controls your voluntary muscles - the ones that move when you want them to. The cerebellum is a motor region of the brain, dealing with the subconscious movements of the muscles. This butterfly-shaped section is the second largest area of the brain. The cerebellum deals with…
Of all the muscles contracting simulataneously, the one that is mainly responsible for producing a particular movement is called the prime mover for that movement. The other muscles that help in producing the movement are called synergists. As prime movers and synergists muscles at a joint contract, other muscles, called antagonist muscles, relax.When antagonist muscles contract, they produce a movement opposite to that of the prime movers and their synergist muscles. -- I wrote kind…
