Exempel på hur du använder SPERMATOZOON i en mening

• A spermatozoon is a moving form of the haploid cell that is the male gamete that joins with an ovum to form a zygote.
• The acrosome is a membrane-bound organelle of Golgi apparatus origin, commonly located at the tip of the head of the mature spermatozoon, which contains a variety of enzymes and antigens required for fertilization.
• The form of anisogamy that occurs in animals, including humans, is oogamy, where a large, non-motile egg (ovum) is fertilized by a small, motile sperm (spermatozoon).
• They may allow for denser packaging of DNA in the spermatozoon than histones, but they must be decompressed before the genetic data can be used for protein synthesis.
• At the beginning of the stage, the spermatid is a more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria; by the end of the process, it has radically transformed into an elongated spermatozoon, complete with a head, midpiece, and tail.
• In fish, he discovered calcium-dependent, chemotactic movement of spermatozoa into the micropyle through which the fertilizing spermatozoon enters the egg.
• In oogamy the large female gamete (also known as ovum) is immotile, while the small male gamete (also known as spermatozoon) is mobile.
• Changes in pH both controls and activates the MSP polymerization throughout spermatogenesis by a pH gradient within the pseudopod of the spermatozoon: assembly occurs at the leading edge where the pH is high, and disassembly of the filaments occurs at the base where the pH is lowered.
• In addition to the two pairs of book lungs, other synapomorphies of Tetrapulmonata include a large postcerebral pharynx (reduced in Uropygi), prosomal endosternite with four segmental components, subchelate chelicerae, a complex coxotrochanteral joint in the walking legs, a pretarsal depressor muscle arising in the patella (convergent with Dromopoda, lost in Amblypygi), a pedicel formed, in part, by ventral elements of the second opisthomal segment and a spermatozoon axoneme with a 9+3 microtubule arrangement.
• The term zooid has historically also been used for an organic cell or organized body that has independent movement within a living organism, especially a motile gamete such as a spermatozoon (in the case of algae now zoid), or an independent animal-like organism produced asexually, as by budding or fission.
• The protein is secreted from non-ciliated oviductal epithelial cells and associates with ovulated oocytes, blastomeres, and spermatozoon acrosomal regions.
• gendarussa leaf extract was proven to potentially become a male, non-hormonally contraceptive method due to its competitive and reversible inhibition of the spermatozoon hyaluronidase enzyme.
• Introduced in 2001, the intracytoplasmic morphologically selected sperm injection (IMSI) procedure changed the perception of how a spermatozoon suitable for fertilization (via injection into the egg) should appear.
