Which cells are not considered somatic cells?

Sperm cells are classified as gametes rather than somatic cells. Somatic cells are all the body cells except for the reproductive cells, which include sperm and egg (oocyte) cells. Skin cells, muscle cells, and nerve cells, on the other hand, are all examples of somatic cells that contribute to the structure and function of the body. In essence, while somatic cells are involved in the physical makeup and functioning of an organism, gametes like sperm are specifically involved in sexual reproduction and are not considered part of the body's somatic cell line.
