NSG 531 Rush Advanced Pharmacology: Exam 3 Questions With Correct Answers Latest Updated 2024/2025 / Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean ...

Positive Babinski sign C. Decreased deep-tendon reflexes D. Ataxia Rationale: Dysphagia, or difficulty swallowing, can occur as a result of damage to cranial nerves IX (glossopharyngeal) o...

BIO 669 Quiz 2 Latest; (2024/2025) Questions and Answers 100% Correct.(33 Q & A) 1. When both Na+ and K+ are permeable at the same time (as in opening ion channels at the neuromuscular junction allowing both to cross), what will happen to the membrane potential? 1. Graded potentials are all of the following EXCEPT: 2. Movement of potassium down its electrochemical gradient will result in what effect on membrane potential? 3. The reticular formation is responsible for: 4. Damage to...

Nerve Conduction Studies A+ GRADED A-waves - ANS Sometimes called Axon reflex. Seen when using sub-maximal stimulation during the F-wave recording. Consistent in latency and amplitude and usually occurring before the F-wave. Thought to be a result of reinnervation of the nerve. Abduct - ANS Move away from the median plane Abductor Digiti Minimi (ADM or ADQ) - ANS Sometimes called abductor digiti quinti. Ulnar innervated muscle on the medial side of the little...

C5-C6; upper trunk; lateral cord What are the five major nerves that come out of the brachial plexus? musculocutaneous nerve axillary nerve radial nerve median nerve ulnar nerve What parts of the brachial plexus make up make up the anatomical course of the radial nerve? C5-C8; ALL trunks; posterior cord What are the interconnections of the brachial plexu...

Nerve conduction study Nerve conduction study - ANS -recording of evoked responses produced by electrically stimulating a nerve. -to see if the nerve is conducting an impulse slower than normal -If there is a decrease in conduction velocity (speed) then there will be an increase in latency (time). Clinical questions for NCS - ANS Are peripheral nerve fibers compromised? Are sensory fibers, motor fibers, autonomic fibers or all three involved? Where is the nerve le...

Nerve Conduction Board Exam - Practice Questions And Answers The ulnar nerve is a branch of which cord of the brachial plexus? a. medial b. lateral c. posterior d. upper a. medial With Martin-Gruber Anastomosis you will see? a. the median wrist response is smaller than the elbow response. b. when performing ulnar nerve stimulation the elbow response is smaller than the wrist. c. an ulnar conduction block is seen in the forearm d. both a and b can be correct e. all the above ...

EMG/NPhysiology of nerve conduction Membrane potential - ANS An electrical potential difference (voltage) across the membrane, resting =-70mV. Negative ions in cytosol. Positive ions in extracellular fluid. (ECF) Electrochemical gradient - ANS Ions move across membrane down gradient. More sodium outside, more potassium inside. Action potential - ANS Two phases depolarizing and repolarizing. Depolarizing - ANS Neg membrane potential becomes positive. ...
