Explain smooth muscle tissue.

(N/A) Smooth muscle tissue is a type of non-striated,involuntary muscle found in the walls of hollow internal organs such as the stomach,intestines,blood vessels,and urinary bladder.
$1$. Structure: The cells are fusiform (spindle-shaped) and taper at both ends. They do not show striations,hence the name 'smooth'. Each cell contains a single,centrally located nucleus.
$2$. Function: These muscles are involuntary,meaning they are controlled by the autonomic nervous system and are not under conscious control.
$3$. Characteristics: They contract slowly and can remain contracted for long periods without fatigue. They are held together by cell junctions and bundled together in a connective tissue sheath.
