Question

question 1 (mandatory) (1 point) what is the most outer covering (made up of areolar connective tissue sheath) of a muscle fiber called? epimysium endomysium sarcolemma perimysium question 2 (mandatory) (1 point) the plasma membrane of a muscle fiber (cell) is called the ______. sarcoplasmic reticulum endomysium sarcomere sarcolemma

Explanation:

1. For Question 1: The most outer covering of a muscle fiber made of areolar connective - tissue sheath is the endomysium. Epimysium covers the whole muscle, perimysium covers muscle fascicles, and sarcolemma is the plasma membrane of the muscle fiber.
2. For Question 2: The plasma membrane of a muscle fiber (cell) is called the sarcolemma. Sarcoplasmic reticulum is involved in calcium storage, endomysium is connective tissue around single fibers, and sarcomere is the basic contractile unit of muscle.

Answer:

Question 1: endomysium
Question 2: sarcolemma
