dermal papilla definition anatomy

Epidermis 13. Dermatology: Definition. Langerhans cells 16. DP is a group of specialized dermal fibroblast cells. Medical definition of papillary layer: the superficial layer of the dermis raised into papillae that fit into corresponding depressions on the inner surface of the epidermis. The dermal papilla is responsible for regulating the hair cycle and hair growth and is also comprised of androgen … Hypodermis 14. n. Any of the superficial projections of the corium or dermis that interlock with recesses in the overlying epidermis, contain vascular loops and specialized nerve endings, and are arranged in ridgelike lines most prominent in the hand and foot.papilla of corium It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. The establishment of a dermal papilla (DP) is vital to the development of all hair follicles. Areolar connective tissue 8. Dermal papillae 10. Melanocyte 4. Tiny smooth involuntary muscle, attached to hair follicle and dermal papillae and cotracts when cold or frightened and produces goosebumps Sebaceous Gland a cutaneous gland that secretes sebum (usually into a hair follicle) for lubricating hair and skin Dermis 11. Term. Epidermis: Definition. Mucous membrane 5. Anatomy and Physiology. Capillaries 9. Total Cards. Description. Pigmentation 6. Fibroblast 3. Backer Chapter 4: The Skin and Its Parts 1. study of the structure, function, and disorders of the integumentary system: Term. Chapter 5- Integumentary System. The projections of the dermis are called dermal papillae and those of the epidermis, epidermal ridges (pegs), because of their appearance in vertical sections of the skin. They are derived from the embryonic mesoderm They aggregate in the dermis just below the epidermis. Angiogenesis 2. Adipose tissue 7. dermal papilla: (plural = dermal papillae) extension of the papillary layer of the dermis that increases surface contact between the epidermis and dermis dermis: layer of skin between the epidermis and hypodermis, composed mainly of connective tissue and containing blood vessels, hair follicles, sweat glands, and other structures NAME:_____ DATE:_____ Anatomy & Physiology Mr. A high power view of the dermo-epidermal junction shows the characteristic architecture of a Meissner's corpuscle occupying a portion of a dermal papilla. The distinctive sheath of modified Schwann cells surrounds one or two nerve fibers poised to detect fine touch of the overlying epidermis. The hair follicle is an organ found in mammalian skin. Desquamation 12. The dermis consists of two layers: The papillary layer is a thin outer layer of areolar connective tissue with fingerlike projections called dermal papillae that protrude into the epidermis.In the hands and feet, the dermal papillae generate epidermal ridges (sweat from the epidermal ridges leaves fingerprints).
