DAANCE module 1 study guide Neurons - Cells of the nervous system Action potential - The nerves threshold of stimuli Terminal button - The bulge at the end of the nerve touches the next nerve Synaptic cleft - When advancing impulse gets to the synapse it must jump accross the gap between the two nerves The cerebral cortex - Responsible fir thiught learning memory consciousness and feeling of sensation such as pain and heat Cerebellum - Center for motorfunction Medulla oblongata - Control center for maintanence of blood pressure pulse respiration. Autonomic center Central NC - Brain and spinal colulm Peripheral NC - sensory and motor nerves Cranial nerves - Olfactory-smell 1st Optic-seeing2nd Trigeminal- teeth and jaw 5th Facial- facial expression 7th Auditory- hearing 8th Mandibular block - Anesthetizes all mandibular teeth chin and liponsame side Posterior superior alveolar block - Anesthetizes the branches for the posterior portion of the max alveolus Myocardium - Heart muscle capable of pumping 5 quarts of blood per minute Autonomic nervous system - Regulates organs snd other functions that take place involantary like breathing beating heart Homeostasis - A constant state Sympathetic system - Speeds up (flight or fight) Parasympathetic system - Slows down Baroceptors - Receptors located in the walls of the aorta, corotid arteries, and ventricles of the heart that respond to increased pressure by decreasing sympathetic output and increasing paradympathetic out put to decrease heart rate and blood pressure Coronary sinus - Blood from veins of the heart muscle itself is returned via the... Pulmonary veins - Only viens that return oxygen rich blood toheartfrim lungs Arteries - All cessells leading away from the heart Vein
