Question 5 0.4 pts (Ch. 12.1: Skeletal Muscle) For this question think of the relationship between muscle length and tension, and consider the initial tension generated (not shortening the muscle completely). When does a skeletal muscle generate the most tension? When the myosin light chain kinase (MLCK) is phosphorylated. When it is very short at the beginning of the contraction When it is a medium length at the beginning of the contraction. When it is very long at the beginning of the contraction When the end-diastolic volume (EDV) is the greatest Question 6 0.4 pts (Ch. 12.1; Skeletal Muscle) What would generate the most force? Activating a motor unit in the thigh starting in the middle of its length O Activating a motor unit in the thigh starting at its maximal length All of the answers would generate equal force because they activate skeletal muscle. Activating a motor unit in a finger starting at its maximal length Activating a motor unit in a finger starting at its minimum length Question 7 0.4 pts (Ch. 12.1: Skeletal Muscle) The T tubules sequester calcium to release upon muscle stimulation. are invaginations of the plasma membrane (sarcolemma) into the interior of a muscle cell wrap around axons to electrically insulate them. have a high concentration of nicotinic acetylcholing receptors. shorten to contract the muscle. Question 8 0.4 pts (Ch. 12.1: Skeletal Muscle) in a skeletal muscle the surround(s) the muscle fiber, muscle fascicle sarcoplasm, muscle fascicle O connective tissue, muscle fascicles blood vessels, muscle O myofibrils, sarcoplasmic reticulum
