Adnexal is an adjective that pertains to the anatomical structures or parts that are closely connected or associated with another main structure. The term adnexal is often used in medical contexts to describe various appendages or annexes of the body, particularly in relation to the skin, eyes, or reproductive organs.
In dermatology, adnexal structures refer to the different appendages of the skin such as hair follicles, sweat glands, and sebaceous glands. These adnexal structures play vital roles in maintaining the overall health and function of the skin.
In ophthalmology, the adnexa of the eye include the eyelids, eyelashes, eyebrows, and the lacrimal apparatus. These adnexal structures are crucial in protecting the eye from foreign objects, aiding in the production and drainage of tears, and contributing to visual aesthetics.
In gynecology, the adnexa of the reproductive system are the structures adjacent to the uterus, primarily the ovaries, fallopian tubes, and their associated ligaments. The adnexal structures are integral in the process of reproduction, including ovulation, fertilization, and the transport of the developing embryo to the uterus.
Overall, adnexal refers to these different accessory structures that are closely connected to or associated with a main anatomical structure, serving important functions in various systems of the body.
