Question

Skeletal muscle fibers arise from embryonic cells called ________.
A) myotomes
B) myoblasts
C) myomeres
D) myofilaments
E) myofibrils

Accepted Answer

Skeletal muscle fibers arise from myoblasts, which are embryonic cells that fuse together to form mature muscle fibers. Myotomes are groups of muscle fibers innervated by a single nerve root, myomeres are segments of muscle tissue in fish, and myofilaments and myofibrils are structures within muscle fibers.
