Q:

A Sarcomere is the distance between two

A) Z discs B) H zones
C) A bands D) I bands
 
Answer & Explanation Answer: A) Z discs

Explanation:

A sarcomere is the basic unit of striated muscle tissue. It is the repeating unit between two Z lines.

Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis. Muscle fibers contain numerous tubular myofibrils. Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes.

 

A muscle fiber from a biceps muscle may contain 100,000 sarcomeres.
