it is strongly connected with cerebral cortex and thalamus but not direct. This plays a role in determining what movement planned by the cortex gets executed and can abort planned movements; it prevents unsuitable movement from occurring. Degeneration may result in: HYPOkinesia - loss of movement HYPERkinesia - excess movement

it is task specific - the loss of inhibitory function in the basal ganglia and motor cortex

it contributes to co-ordination, precision and timing of the movements

a sheet of neural tissue on the outside of the cerebrum. it is divided into loves which control specific functions e.g. movement, vision, hearing, touch

it serves as a conducting zone where the main part of the brain sends signals to initiate the movement. it is in charge of the basic bodily functions such as breathing, blood pressure and digestion

Bundles of nerve tissue that is protected by the backbones. it is the pathway which connects the brain to the muscle

A nerve which responds to a specific stimuli, which tells the brain what is going on in the environment. e. g. proprioceptors respond to the stretching of the muscle, so it relays information to the brain that the muscles are being stretched. e. g. a taste receptor recognises a specific taste and tells the brain if it is sweet, bitter, sour etc

acts as a relay station and sorts sensory information that is on its way to the cerebral cortex

a motor phenomenon affecting golfers. it is involuntary movements during chipping and putting (fine motor control)
