APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Smooth muscle and Cardiac muscles are involuntary muscles which are found in organs where voluntary movement is impossible, like the alimentary canal or the heart.

Detailed explanation-2: -Smooth muscle differs from skeletal muscle in function. Unlike skeletal muscle, smooth muscle is capable of maintaining tone for extended periods and often contracts involuntarily. At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle.

Detailed explanation-3: -Smooth muscle consists of two types: single-unit and multi-unit.

Detailed explanation-4: -Types of Smooth muscle Smooth muscles are of two types. They are: Single-unit (visceral) smooth muscle: All the cells function collectively and simultaneously as a single unit (unitary). Multiunit smooth muscle: It is a type of muscle in which all the cells cannot function collectively and work independently.
