Document Summary

Visual information is required to locate the target. Frontal lobe motor areas plan the reach and command the movement. Motor neurons carry messages to muscles of forearm and hand. Sensory receptors on fingers send message to sensory cortex saying cup has been grasped. Spinal cord carries sensory information to the brain. Basal ganglia judge grasp force and cerebellum corrects. Corticobulbar tracts: paths from the cerebral cortex to the pons and medulla to control facial movement (motor neurons for facial movement is controlled by cranial nerve 7) Do not go very far (mostly stay in the head) Corticospinal tracts: paths from the cerebral cortex to the spinal cord. Controls movement in peripheral area (hands and feet) Allows control of muscles of the neck, should, and trunk. Enables movements such as walking, turning, bending, standing up, and sitting down. Cortical motor disorders have to do with cerebral cortex such as huntington"s in which involuntary movements plague the patient.
