The Thin Myofilament of the Skeletal Muscles is Made Of

Question

The thin myofilament of the skeletal muscles is made of
A) sarcomere
B) actin
C) myosin
D) Z lines

Accepted Answer

The thin myofilament of the skeletal muscle is primarily composed of actin. This filament is responsible for sliding past the thick myofilament, which is primarily composed of myosin, leading to muscle contraction. Sarcomeres are the basic units of muscle contraction, and Z lines are structural proteins that help organize the sarcomeres.
