NEET BIOLOGY

Detailed explanation-1: -Smooth muscle cannot be controlled consciously and thus acts involuntarily. The non-striated (smooth) muscle cell is spindle-shaped and has one central nucleus. Smooth muscle contracts slowly and rhythmically.

Detailed explanation-2: -Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles.

Detailed explanation-3: -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. Cardiac muscle tissue is only found in the heart, and cardiac contractions pump blood throughout the body and maintain blood pressure.

Detailed explanation-4: -Smooth muscles-sometimes also called involuntary muscles-are usually in sheets, or layers, with one layer of muscle behind the other. You can’t control this type of muscle. Your brain and body tell these muscles what to do without you even thinking about it.

Detailed explanation-5: -At a cellular level, smooth muscle functions as an involuntary non-striated muscle. Smooth muscle contains thick and thin filaments that do not arrange into sarcomeres, resulting in a non-striated pattern.
