MUSCLE PHYSIOLOGY

Detailed explanation-1: -Smooth muscle tissue cells have four characteristics: they are involuntarily regulated, not striated, not branched, and have a single nucleus. Smooth muscle is a form of muscle tissue that is used to apply pressure to vessels and organs through different systems.

Detailed explanation-2: -Non-striated muscles are smooth and devoid of striations. Found in the hollows of internal organs such as the stomach, intestines, and urine bladder, among other places. They are also known as involuntary muscles because their activation is not under the control of the human.

Detailed explanation-3: -Smooth muscle is an involuntary non-striated muscle, so-called because it has no sarcomeres and therefore no striations (bands or stripes). It is divided into two subgroups, single-unit and multiunit smooth muscle. Within single-unit muscle, the whole bundle or sheet of smooth muscle cells contracts as a syncytium.

Detailed explanation-4: -Visceral muscle is the other name of smooth muscle and not striated muscle.

Detailed explanation-5: -Smooth muscle cell shape. The smooth muscle cell is fusiform in shape. The filaments. Single nucleus. Elasticity. Contractility. Lack of sarcomeres. Lack of a tropomyosin complex. 16-Jun-2022
