Document Summary

Neural basis: reflex, nerve impulse, action potential, communication by. Brain basis: nervous system structure, localization of function, disorders, neurotransmitters lateralization. 2/10 the neuron reflex - an automatic, stereotyped movement produced as the direct result of a stimulus. Knee tap sensory neuron from muscle spinal cord single synapse in reflex reflex, motor output cause thigh muscle to contact. Also neuron going upwards to the brain. Although it can be excited by brain, response can be inhibited by the brain inhibition - response is kept from happening. Covered by myelin sheath aka covering of axon. Only covering little stretches with opening in between. Openings /interruptions in between myelin sheath that cover axon terminal endings (or terminal buttons) Ending of the splitting of the axon. Ms disease - immune system attacking myelin sheath. How does a neuron fire ? (what is the nurse impulse?) there can be different kinds of connections between neurons.
