Auricular glands

Auricular Glands

The auricular glands are a group of exocrine glands located in the human ear. They are part of the integumentary system, which includes the skin and its appendages. The auricular glands are specifically found in the external auditory canal, where they secrete cerumen, commonly known as earwax.

Function

The primary function of the auricular glands is the production and secretion of cerumen. This substance plays a crucial role in maintaining the health of the ear. It acts as a natural barrier, protecting the ear from foreign particles such as dust, bacteria, and insects. Additionally, cerumen helps to lubricate the ear canal, preventing dryness and irritation.

Anatomy

The auricular glands are a type of sebaceous gland, which are found throughout the skin, except on the palms of the hands and the soles of the feet. They are typically associated with hair follicles, but in the case of the auricular glands, they exist independently. These glands are composed of secretory cells that produce the oily substance that makes up cerumen.

Clinical Significance

Dysfunction of the auricular glands can lead to a number of ear-related conditions. Overproduction of cerumen can result in cerumen impaction, a common cause of hearing loss. Conversely, underproduction can lead to dry and itchy ears. Infections of the auricular glands, while rare, can also occur and may result in pain and swelling in the affected area.
