In response to the hormones, secondary sex traits emerge. When a child reaches puberty, the ovary starts to secrete more hormones. Granulosa cells which have modified from flat to cuboidal and proliferate to form a stratified epithelium surround them.īlood vessels and lymphatics are also found in the ovary. The cortex and medulla are difficult to differentiate, but follicles are rarely located in the medulla.įollicular cells are flat epithelial cells which arise from the ovary's surface epithelium. The follicle frequently contains the theca of follicle, antrum, and liquor folliculi. The cumulus oophorus, membrana granulosa (and the granulosa cells within it), zona pellucida, corona radiata, and primary oocyte are all found in the follicles. States that the ovarian cortex is the outer layer, which is made up of ovarian follicles and stroma in between. Microanatomy: The germinal epithelium is a membrane that covers the top of the ovaries and is made up of simple cuboidal-to-columnar shaped mesothelium. Parts of the fallopian tube, ovarian ligament, mesovarium, and ovarian blood vessels make up the ovarian pedicle. The mesovarium is the portion of the uterus's thick ligament that protects the ovary. The ovaries are exposed in the peritoneal cavity, but they are attached to the body wall by the ovary's suspensory ligament, which seems to be a posterior extension of the uterus' broad ligament. Ligaments: The section of ovary shows that ovaries are located inside the peritoneal cavity, on either side of the uterus, and are connected by a fibrous cord known as the ovarian ligament. The hilum is one of the ovaries' other structures and tissues. The infundibulopelvic ligament connects the part of the ovary nearest to the fallopian tube to the tube, and the ovarian ligament connects the other side of the ovary to the uterus. The tunica albuginea is a capsule made up of dense connective tissue.Įach menstrual cycle, ovulation occurs in one of the two ovaries, which releases an egg. Ovary structure reveals that a capsule surrounds the ovaries, which have an outer cortex and an inner medulla. The scale of this region is approximately 4 cm x 3 cm x 2 cm. The ovarian fossa seems to be the region in front of the ureter and the internal iliac artery which is surrounded by the external iliac artery. Each (parts of ovary) ovary is whitish in color and is found in the ovarian fossa, which runs alongside the uterus's lateral wall.
The female gonads are called the ovaries. Because of the hormones it metabolizes, it is often classified as an endocrine gland. Beginning in the prenatal phase and continuing into menopause, the ovary goes through a number of stages. Hormones that play a part in the menstrual cycle and fertility are also secreted by the ovaries. On either side of the body, there is an ovary (from Latin ovarium 'egg, nut'). This travels down the fallopian tube further into the uterus after being released, where it could be fertilized by sperm. These are also not a part of the female reproductive system of the frog.The ovary is a female reproductive organ that contains an egg called an ovum. These tubes provide a passageway from the ovary to the uterus for the egg. Fallopian tubes are also called uterine tubes and these are found only in female mammals. Frog is an oviparous animal because it lays eggs that develop outside the body after being fertilized.
In such animals, fertilization takes place internally and the fertilized egg is implanted in the uterus where it develops till birth. The uterus is found only in those animals which give birth to young ones and the term viviparous is used for these animals. The size of ovaries in the female frog varies considerably in different seasons as in breeding season they become greatly enlarged. The ovary is a multilobed and irregularly folded structure, quite large and hollow sac with greyish or blackish appearance. The two ovaries lie near the kidneys and are attached to the kidneys by mesovarium.
