Skeletal muscle fibers Select one: a. possess striations. b. can contract but are not extensible or excitable. c. do not require nerve innervation to contract. d. increase dramatically in number after birth. e. are found in the walls of the stomach.

Possess striations. (Option A)

Explanation:

Skeletal muscle fibers are known as the type of striated muscle tissues and the somatic nervous system helps to control them. With the help of the bundle of collagen fibers which is called tendons, skeletal muscle cells attached to the bones.

Skeletal muscles are cylindrical and long in structure. While seeing under the microscope they have striated, and this striation occurs by the presence of actin, and myosin contractile proteins. Some functions of Skeletal muscle fibers are:

1) They help in contraction, and cellular physiology.

2) They help in signal transduction pathways.
