Spermatozoa: Anatomy and function - Kenhub The term spermatozoa (singular: spermatozoon), also known as sperm, refers to the male sex cells or gametes They are formed through the process of spermatogenesis, which begins at puberty with the proliferation progenitor (stem) cells called spermatogonia This process takes place within the seminiferous tubules of the testes, supported by sustentocytes or nurse cells, previously referred to
Spermatozoon | definition of spermatozoon by . . . - Medical Dictionary spermatozoon [sper″mah-to-zo´on] (pl spermatozo´a) (Gr ) a mature male germ cell, the specific output of the testes, which fertilizes the mature ovum (secondary oocyte) in sexual reproduction It is microscopic in size, looks like a translucent tadpole, and has a flat elliptical head containing a spherical center section, and a long tail by which

Sperm | Definition, Function, Life Cycle, Facts | Britannica Sperm, male reproductive cell, produced by most animals In higher vertebrates, especially mammals, sperm are produced in the testes The sperm unites with (fertilizes) the ovum (egg) of a female to produce a new offspring Mature sperm have two distinguishable parts, a head and a tail
Sperm Cell Unraveled: Anatomy, Functions Key Diseases - Microbe Notes The sperm cell, also known as the spermatozoon, is the male reproductive cell produced from the male reproductive organ It unites with the female egg cell to produce a diploid zygote The sperm cells are formed through the process of spermatogenesis in the seminiferous tubules of the testes Once matured, sperm cells are released into the epididymis, where they gain motility and become ready
Understanding the spermatozoon - PubMed The former perception of the spermatozoon as a delivery device of the male genome has been expanded to include a new understanding of the cell's complex role in fertilization Once the spermatozoon reaches the oocyte, it triggers egg activation and orchestrates the stages of pre- and post-fertilizat …
Understanding the Spermatozoon - SpringerLink The general component of mammalian spermatozoa consists of the primary entities, the head and the flagellum, which are both enclosed by a regionally differentiated plasma membrane (Fig 1) The most recognized organelles of the head are the nucleus and acrosome, a membrane-limited vesicle that houses several hydrolytic enzymes and is located over the apex of the nucleus
