Auricular cartilage

**Cartilage of the ear (tympanic) cavity** is a paired cartilage of osteochondral origin, having the shape of the auricle, its anterior edge, and also partially connecting its outer and inner processes. The length of the cartilage ranges from 85-90 mm (according to other sources - up to 120 mm). The anteroposterior diameter is 30-35 mm. The cartilaginous part of the auricle consists of a connective tissue skeleton, perichondrium and a thin layer of hyaline (transparent) cartilaginous tissue. The skeleton is a strong frame, the connective tissue is elastic and has cellular potential for growth. The skin of the outer ear is a derivative of the epidermis. The inner layer of the dermis consists of papillae, separated by thin layers of loose fibrous connective tissue - the reticular dermis, which is connected to the hair follicles and sebaceous glands. The upper layer of the dermis is represented by the skin of the outer ear itself, along with hair and the glandular ear glands located on it: prostate gland - duct + middle tympanic gland. It is connected by an applicator process to the papillary layer of the entire cartilage. The suspensory glands have a superior excretory duct passing through the earlobe. The inferior excretory duct passes between the cartilaginous base and the processes of the large cartilage of the auricle.
