MICROANATOMY

Detailed explanation-1: -Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. Cardiac muscle – the muscle specific to the heart.

Detailed explanation-2: -Cardiac muscle is highly organized and contains many types of cell, including fibroblasts, smooth muscle cells, and cardiomyocytes.

Detailed explanation-3: -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.

Detailed explanation-4: -Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.

Detailed explanation-5: -Cardiac muscle cells (cardiomyocytes) are striated, branched, contain many mitochondria, and are under involuntary control. Each myocyte contains a single, centrally located nucleus and is surrounded by a cell membrane known as the sarcolemma.
