Solved in 2 steps
- _______can shorten (contract). a. Muscle tissue b. Nervous c. Connective tissue d. Epithelial tissueThe _____ is the basic unit of muscle contraction. a. myofibril b. sarcomere c. muscle fiber d. myosin filamentA bursa ________. surrounds a tendon at the point where the tendon crosses a joint secretes the lubricating fluid for a synovial joint prevents friction between skin and bone, or a muscle tendon and bone is the strong band of connective tissue that holds bones together at a synovial joint
- After death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm. This result is rigor mortis----an unbreakable state of muscle contraction that stiffens the body for a few days until muscles begin to decay. Explain why this contraction occurs.The cells of muscles, myocytes, develop from ________. myoblasts endoderm fibrocytes chondrocytesWhat is the function of synovial membranes?
- What causes the striated appearance of skeletal muscle tissue?Most has collagen and elastin fibers. a. muscle tissue b. nervous tissue c. connective tissue d. epithelical tissueDepolarization of the sarcolemma means ________. the inside of the membrane has become Less negative as sodium ions accumulate the outside of the membrane has become less negative as sodium ions accumulate the inside of the membrane has become more negative as sodium ions accumulate the sarcolemma has completely lost any electrical charge
- Which of the following is not a true statement comparing exoskeletons and endoskeletons? Endoskeletons can support larger organisms Only endoskeletons can grow as an organism grows Exoskeletons provide greater protection of the internal organs Exoskeletons provide less mechanical leverage.What aspect of creatine phosphate allows it to supply energy to muscles? ATPase activity phosphate bonds carbon bonds hydrogen bondsFigure 38.37 Which of the following statements about muscle contraction is true? The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The power stroke occurs when ADP and phosphate dissociate from the myosin head. The power stroke occurs when ADP and phosphate dissociate from the actin active site. The power stroke occurs when Ca2+ binds the calcium head.
