Question

question 25 1 pts the muscles ability to stretch or extend and to return to its resting length is called excitability. irritability. contractibility. extensibility. question 26 1 pts the four kinds of protein that make up myofilaments are myosin, actin, tropomyosin, and myofibril. troponin, and myofibril. troponin, and trypsin. tropomyosin, and troponin. question 27 1 pts if a structural classification is used, joints are named according to the type of ____ tissue that joins the bones together. epithelial adipose muscle connective

Explanation:

• Question 25: Extensibility is the property of muscle to stretch and return to resting length. Excitability is the ability to respond to stimuli, irritability is related to sensitivity, and contractibility is the ability to shorten.
• Question 26: Myofilaments are made of myosin, actin, tropomyosin, and troponin. Myofibril is a structure composed of myofilaments, and trypsin is an enzyme not related to myofilaments.
• Question 27: Structurally, joints are named according to the type of connective - tissue that joins bones together. Epithelial tissue covers surfaces, adipose tissue is for fat storage, and muscle tissue is for movement and not what joints are classified by in terms of structure.

Answer:

• Question 25: extensibility
• Question 26: tropomyosin, and troponin
• Question 27: connective
