Question

What are the spindle-shaped cells present in the human body called?

Answer 1

The spindle, uninucleate, unbranched cells are typical types of cells found in the smooth muscle. Three different types of muscles exist in the body: Smooth, Skeletal and Cardiac, respectively with their particular characteristics. The above characteristics refer to the smooth muscle.

Complete answer:
Muscle cells are the spindle-shaped cells found in the human body. They have a spindle shape because they control the human body's contraction and relaxation. The connective tissues encircle these cells. Smooth muscle tissue has a structure that is distinct from that of other muscle tissue subtypes.
The body contains four kinds of animal tissues: Connective tissues, epithelial tissues, Neuronal and muscular tissues. Muscle fibres consist of different types of muscle cells that play an important role in the contraction and the movement of the parts of the body. The muscle tissues of the muscle come from three categories: skeletal, smooth, and cardiac.
Typical feature Muscles of smoothness are cells with a single nucleus spindle-shaped cell. They are referred to as smooth muscles because there are no striations in them as striated muscles have.
Slowly and rhythmically contract. The autonomous nervous system controls them.
Smooth muscle contraction causes peristalsis. Additional smooth muscle examples are:
Examples: eye iris, blood vessels, lung bronchial, urinary, uterine and bladder.

Note:
Similar to smooth muscle cells, cardiac muscles are also uninucleate and involuntary, but cylindrical and branched. Special features of cardiac muscles are intercalated discs. The streaked, cylindrical, unbranched, multiple nucleate and volunteer muscles are contrary to the smooth muscles.
