Title: Anatomy / 14 Skin

Q: layers
of skin with characteristics
A: The skin consists of three primary layers with the following characteristics:
- Epidermis: Composed of stratified squamous epithelium.
- Dermis: Made of high-fiber connective tissue; contains capillaries, nerves, and cutaneous glands (sweat, sebaceous, scent).
- Subcutis: Consists of loose connective tissue and fat; contains capillaries and nerves.

Q: sensory
organs of the skin with location
A: - Merkel-cells: Located in the epidermis;
- Meissner-tactile corpuscles: found in the papillary layer of the dermis. They are responsible for light touch sensitivity and are most concentrated in fingertips, lips, and palms.
- Vater-Pacini-lamellar corpuscles: Located in the subcutis;
- Free nerve endings: Located mostly in the dermis and hair follicles. These serve as receptors for mechanics, pain, pressure, and temperature

Q: skin
appendages (= Anhängsel; Auswüchse)
A: Nails: protective covering made of keratin, Consist of the nail body, nail wall, nail root, lunula, nail pocket, nail bed, and nail fold;
cutaneous glands: sweat glands (thermoregulation), scent glands, sebaceous (Talg) glands;
hair: lanugo and terminal hair, connected to arrector pili muscle
