Which of the following muscular tissues are involuntary? (choose all that apply)
A
Cardiac
B
Skeletal
C
Smooth
Explanation: 

Detailed explanation-1: -The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-2: -At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle. Smooth muscle consists of thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern.

Detailed explanation-3: -Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.

Detailed explanation-4: -The smooth muscles make the wall of the vessels and visceral organs of our body whereas the cardiac ones are the constituent muscle cell of the heart. Complete step by step answer: Both smooth and cardiac muscles are involuntary in nature.

Detailed explanation-5: -Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and striated, and smooth muscle is involuntary and non-striated.
