"Ask the subject to smile broadly. Record any asymmetry or drooping in the face." What cranial nerve is this assessing? - Cranial Nerve VII (Facial) "Pulse deficit" describes a difference between pulse rate assessed by palpating a radial pulse and heart rate assessed by auscultation (listening) or ECG. What could account for pulse deficit? - Pulse deficits can occur when there are circulatory problems, atrial fibrillation, or valvular disturbances. A difference between the palpated hear...

Describe the events at the axon terminal that cause one neuron to release a neurotransmitter onto another. - The action potential travels down the axon and gets to the axon terminal, which causes calcium to enter the axon terinal, which causes the release of the neurotransmitter by exocytosis into the synaptic cleft. The post synaptic neuron, dendrite opens voltage gated channels and allow Na+ in and K+ out. A hypothyroid individual shows no increase in metabolic rate when injected with TSH...

Initially there is a high concentration of sodium on the left side of a beaker of water. What is likely to happen (with regard to movement of ions and/or water) in this beaker? - The sodium will move to the right side of the beaker until it is spread out approximately the same throughout the beaker. What is the proper term for the process that is occurring in the beaker on the previous card? - Diffusion A red blood cell is surrounded by a solution containing a higher concentration of solut...

3 factors that affect muscle tension - Length, muscle force, angle of pull A difference between the palpated heart rate and the heart rate calculated by auscultation is termed? - Pulse deficit Although we typically measure respiratory rate as a vital sign, what respiratory system parameter might be more useful in assessing an individual's health? - Respiratory volumes measure oxygen levels with pulse ox. Area with only thick filament - A band Area with only thin filaments - I band CN I ...
