The pons serves as a bridge from the cortex to the cerebellum. G. Parkinson’s disease is causing Annette’s muscles to become increasingly rigid or hypertonic. Maintenance of normal muscle tone is controlled by which part of Annette’s brain? The cerebellum maintains normal muscle tone. H. Which of the meninges did

contraction and relaxation of muscles. With mostly everything we do the cerebellum must receive constant input from our senses and make constant adjustments to the muscles to ensure balance maintenance. This is pretty much the role of propriorception‚ and it is usually done completely subconsciously. Without it‚ we would constantly need to watch our feet to make sure we stay balanced when walking. There are many inputs the cerebellum receives from the body that allows it to direct the muscles contractions

Secured by the skull‚ the mind is made of parts called the cerebrum‚ cerebellum‚ and brainstem. The brainstem goes about as a hand-off focus interfacing the cerebrum and cerebellum to the spinal string. The cerebrum gets data through the five detects: locate‚ notice‚ touch‚ taste‚ and hearing. It demonstrates the faculties in a way that has importance for us‚ and can store

The brain has five key parts that work together to make your brain function; the cerebrum‚ cerebellum‚ brain stem‚ pituitary gland‚ and the hypothalamus. All this fits inside your brain which is about the size of a head of cauliflower. The cerebrum is the biggest part of your brain; it makes up about 85% of your brains weight. It is the thinking

of hands‚ speech‚ and eye movements.” This is similar to other muscular dystrophy disorders such as motor neurone disease or in other words ALS because it is a progressive disease and ataxia relates to the cerebellum in the brain. Ataxia is the degeneration of the cells within the cerebellum part of the brain. According to Genetic Home Reference‚ this disease affects‚ “1 to 2 per 100‚000 people worldwide.” This is a considerable amount of people given how many people are living in the world today

Method: * We placed the brain so that the cerebral hemispheres are at the top of the board and the brain stem is at the bottom. * My group identified the external features of the brain: the cerebral hemispheres‚ cerebellum and brain stem. * We also used the forceps and tried to lift the meninges (membranes protecting the brain). We then observed the cerebral fluid between these membranes and the hemispheres. * My group carefully observed the overall appearance

4.1: The healthy and damaged brain The brain has three main parts the Cerebrum‚ the Cerebellum and the brain stem. The brain is divided into regions that each control different functions. The Cerebrum: The Cerebrum is the biggest part of the brain it makes up around 85% of the brains weight this is because it is the thinking part of your brain and it also controls the voluntary muscles. So without your Cerebrum then daily activities such as dancing or kicking a ball wouldn’t be possible. The cerebral
