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
Sperm | Definition, Function, Life Cycle, Facts | Britannica sperm, male reproductive cell, produced by most animals With the exception of nematode worms, decapods (e g , crayfish), diplopods (e g , millipedes), and mites, sperm are flagellated; that is, they have a whiplike tail In higher vertebrates, especially mammals, sperm are produced in the testes
Molecular Biology of Spermatozoa - PMC The spermatozoon is a very special cell; it is generated in the male reproductive tract and has to travel to the female reproductive tract, of another individual, to fertilize an egg However, through this amazing journey, it has to be able to respond and adapt to dramatically changing environments
Sperm Cell Unraveled: Anatomy, Functions Key Diseases The haploid spermatids mature and differentiate into mature sperm cells called spermatozoa through the process of spermiogenesis This maturation process involves specific changes in the structure of the sperm cell The nucleus assumes an oval shape forming the head of the sperm
Sperm Cell – Definition, Structure, Functions - Biology Notes Online What is Sperm Cell? Sperm cells, scientifically referred to as spermatozoa, serve as the male gametes in sexual reproduction These specialized cells originate from the male reproductive organs and play a crucial role in fertilization, as they unite with female egg cells to create a diploid zygote, initiating the development of a new organism
Sperm Cell - The Definitive Guide | Biology Dictionary Sperm cells (spermatozoa) were first described in the late seventeenth century by Antonie van Leeuwenhoek Sperm Cell Structure A sperm cell is one of the smallest cells of an organism and is produced by most animals and some plants Spermatozoa are divided into motile and non-motile groups
Spermatozoa (sperm) - MyHealth.
