Unformatted text preview: Somatic motor Muscle t o move eye FINAL EXAM! THINGS BIRD SAID WE NEED TO KNOW! Neuron (Draw label describe)- Fundamental unit of structure of nervous system.- BE ABLE TO LABEL THE NEURON, FUNCTIONS AND OTHER NAMES FOR THE INDIVIDUAL STRUCTURES. SYNAPSE- The a.p. arrives down the pre-synaptic neuron to primary messenger cells. The primary messenger cells release neurotransmitters (chemical messengers- ex. DOPA, serotonin, acetylcholine) that move across the synapse. The neurotransmitters react with secondary messenger cells in the post-synaptic neuron and then the a.p goes to the effecter organ- BE ABLE TO DRAW AND LABEL THE PICTURE OF THE PRE AND POST SYNAPTIC NEURON TYPES OF NEUROGLIA (only need to know this one. MMC) Astrocyte- (support and eat) supportive cell, plays a role blood/brain barrier TYPES OF SENSORY RECEPTORS 1. Mechanoreceptors- respond to mechanical stimuli- compression, bending, stretching 2. Chemoreceptors- respond to chemicals; smell and taste 3. Thermoreceptors- changes in temperature at site of receptor 4. Photoreceptors- respond to light 5. Nociceptors- (pain) respond to painful stimuli MEMORY 1. Sensory- very short term retention of sensory input 2. Short-term- (working memory) it is electrical or chemical and lasts a short time 3. Long term- acquired thru structural changes that increase the effectiveness of synapses (hippocampus & temporal lobes) PHYSIOLOGY OF PAIN 1. Transduction- is the process in which an impulse is generates from a painful stimulus in the periphery and an action potential is initiated 2. Transmission- occurs once the a.p. is initiates. Transmission of the pain and impulse begins 3. Perception- is the process in which the impulse travels to the brain and the pain is identified 4. Modulation- id the process by which the brain perceives the pain and releases neurotransmitters that inhibit the transmission of pain and help produce the analgesic effects NEUROTRANSMITTERS-parasympathetic and sympathetic 1. acetylcholine- (ACE) if this is secreted it is done via cholinergic neuron . This neuron has ....
