Document Summary
Ventro side is motor , dorsal side is sensory. Motor tract: the pathways by which motor signals are sent from the brain to lower motor neurons. Distal muscle more lateral, extension and postural muscle is more ventral. Retinotopic map: mapping of visual input from the retina to neurons, particularly those neurons within the visual stream. Cortex maintain control over all motor pathway. Motor cortex and sensory cortex near each other. Primary motor cortex: m1 is located in the frontal lobe of the brain, generate neural impulses that control the execution of movement. Sma & rma same map as m1 but regulate more complex movement and planning of movement. Prefrontal cortex and posterior parietal cortex area 5,7 also involved in the planning of movement. Homeostasis: is the state of steady internal physical and chemical conditions maintained by living systems. (body temperature stay stable ) Overhydration and dehydration are not correct (kidney can hold 1 liter water for one hour)
