1 CELL PHYSIOLOGY EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ How big is a typical human cell and can you see it with the naked eye? Correct Answer: 10 um and no Why is a cell roughly 10 um? Correct Answer: This size allows the cell to effectively communicate with its environment through its plasma membrane. What would happen if a cell got bigger than 10um? Correct Answer: cell's membrane would not be able to efficiently communicate with its environment due ...

Perimysium bundles muscle fibers together into fascicles; carries the larger nerves and blood vessels as well as stretch receptors called muscle spindles; the sheath of connective tissue surrounding a bundle of muscle fibers Endomysium surrounds each muscle fiber; layer of areolar connective tissue that covers each individual myocyte (muscle fiber or muscle cell); it also contains capillaries and nerves; it overlies the muscle fiber's cell membrane - the sarcolemma Epimysium encloses the enti...

Amerman A&P Ch. 10 Muscle Tissue and Physiology three types of muscle tissue and common function to each - ANS common function: create muscle tension skeletal cardiac smooth other functions of muscle tissue - ANS 1) create movement 2) maintain posture 3) stabilize joints 4) generate heat 5) regulate flow of stuff through hollow organs skeletal muscle tissue orientation and length - ANS muscle cells arranged parallel to each other, some are very long characteristics of skeletal m...

Nurs 5220 Pharmacology NA CV 2024 Exam Questions And Correct Answers What is an action potential? - ANSWER- Fundamental process underlying all electrical activity in the heart. What is the resting membrane potential? - ANSWER- -94 mV, close to the equilibrium potential for K+. What are cardiac muscle fibers? - ANSWER- Cardiac cells that contract and are connected in series to one another with gap junctions. How does the action potential develop in cardiac muscle fibers? - ANSWER- It ...

Cardiac cellular action potential - Answer The cardiac action potential is a short-lasting event in which the membrane potential (the difference of potential between the interior and the exterior) of a cardiac cell rises and falls following a consistent trajectory, similar to the action potential in other types of cells. Cardiac action potentials are generated by the movement of ions through the transmembrane ion channels in the cardiac cells. Phase 4 is the resting membrane potential, an...
