Answer:
smooth muscle
Explanation:
Smooth muscles are one of the three types of muscles based on anatomy, location, and regulation. Smooth muscles lack the striations which are otherwise present in skeletal and cardiac muscle tissue. The absence of striations makes them look nonstriated, which is why they are referred to as smooth.
The action of smooth muscle is usually involuntary and is under the regulation of autonomic (involuntary) division of the nervous system and the hormones released by endocrine glands. T tubule is the extension of sarcolemma into the skeletal muscle fiber and is involved in the conduction of impulses. It is absent in smooth muscles.
Somatic cells or body cells have a dipliod or full set of chromosomes. Gametes or sex cells, also called germ cells, have a hapliod number of chromosomes or half the number. Somatic cells are diploid cells, whereas the gametes are haploid cells. Meiosis does not take place during the production of somatic cells, whereas meiosis takes place during gametogenesis (production of gametes) giving rise to haploid cells. Somatic cells do not fuse during sexual reproduction, whereas gametes fuse during sexual reproduction giving rise to a diploid zygote.Somatic cells are found almost everywhere in the body, whereas gametes are restricted to certain parts
