Answers
Answer:
Explanation:
The corpus luteum (plural: corpora lutea) is a temporary endocrine structure involved in ovulation and early pregnancy. During ovulation, the primary follicle forms the secondary follicle and subsequently the mature vesicular follicle. At ovulation the follicle ruptures expelling the ovum into the fallopian tube.
The endometrium is the lining of the uterus. It is one of the few organs in the human body that changes in size every month throughout a person's fertile years. Each month, as part of the menstrual cycle, the body prepares the endometrium to host an embryo.
The acrosome is a special kind of organelle with a cap-like structure that covers the anterior portion of the head of the spermatozoon. The acrosome is derived from the Golgi apparatus and contains digestive enzymes
A small middle portion of the sperm contains the mitochondria. The tail of the sperm, sometimes called the flagellum, is a slender, hairlike bundle of filaments that connects to the head and middle portion. ... The tail gives the sperm cell movement. It whips and undulates so that the cell can travel to the egg.
In bacteriology, a fimbria, also referred to as an "attachment pilus" by some scientists, is a short appendage found on many Gram-negative and some Gram-positive bacteria, and that is thinner and shorter than a flagellum.
