Adnexa
Adnexa[edit | edit source]
Adnexa refers to the appendages or accessory structures of an organ. In medical terminology, it is most commonly used to describe the structures associated with the uterus, including the ovaries, fallopian tubes, and the supporting ligaments. The term can also be applied to other organs, such as the eye and the skin.
Gynecological Adnexa[edit | edit source]
In gynecology, the adnexa of the uterus include the ovaries, fallopian tubes, and the broad ligament. These structures play a crucial role in reproduction and the menstrual cycle.
- Ovaries: The ovaries are the female gonads responsible for producing ova (eggs) and secreting hormones such as estrogen and progesterone.
- Fallopian Tubes: These tubes transport the ova from the ovaries to the uterus. Fertilization of the ova by sperm typically occurs in the fallopian tubes.
- Broad Ligament: This is a peritoneal fold that supports the uterus, fallopian tubes, and ovaries, helping to maintain their position within the pelvic cavity.
Ocular Adnexa[edit | edit source]
In ophthalmology, the term adnexa refers to the accessory structures of the eye, including the eyelids, lacrimal apparatus, and the extraocular muscles.
- Eyelids: These protect the eye from foreign particles and help to spread tears over the surface of the eye.
- Lacrimal Apparatus: This includes the lacrimal gland and the ducts that produce and drain tears.
- Extraocular Muscles: These muscles control the movement of the eye and are essential for vision.
Dermatological Adnexa[edit | edit source]
In dermatology, adnexa refers to the accessory structures of the skin, such as hair follicles, sebaceous glands, and sweat glands.
- Hair Follicles: These are the structures from which hair grows.
- Sebaceous Glands: These glands secrete sebum, an oily substance that helps to lubricate and protect the skin.
- Sweat Glands: These glands produce sweat, which helps to regulate body temperature.
