Detailed Solution

Antrum is a fluid-filled cavity that forms within a developing ovarian follicle during the menstrual cycle. It's an important part of the maturation process of the follicle, which ultimately leads to ovulation.
The areola is the darker area surrounding the nipple of the breast. It is part of the mammary gland structure and contains small sebaceous glands that help lubricate and protect the nipple during breastfeeding.
The acrosome is a structure found at the tip of the head of a spermatozoon (sperm cell). It contains enzymes that play a crucial role in fertilization by allowing the sperm to penetrate and fertilize the egg.
The ampulla is a dilated portion of the fallopian tube (oviduct) located closer to the ovary. It is a site where fertilization typically occurs. After ovulation, the released egg is captured by the fimbriae of the fallopian tube and transported to the ampulla, where it may meet sperm for fertilisation.
