Question

striations are absent in (1) skeletal muscles (2) cardiac muscles (3) smooth muscles (4) striated muscles​

Answer 1

Answer:

Smooth muscle has no striations, is not under voluntary control, has only one nucleus per cell, is tapered at both ends, and is called involuntary muscle. ... Like skeletal muscle, cardiac muscle is striated, but unlike skeletal muscle, cardiac muscle cannot be consciously controlled and is called involuntary muscle.

Explanation:

smooth muscle is the correct answer

Answer 2

Answer:

smooth muscle

Explanation:

The repeating pattern of sarcomeres joined end-to-end gives rise to the striations seen in the light microscope (2). Smooth muscles, in contrast, lack both Z-lines and aligned, uniform-length thick and thin filaments; striations are therefore absent, creating a “smooth” appearance in the light microscope
