Glands, subcutis and vasculature

- sebaceous glands are holocrine glands that produce sebum
- sweat glands: 2 types, apocrine and eccrine

• apocrine (epitrichial)
• eccrine (atrichial)

- subcutis is composed of fat (panniculus) and loose CT

• functions: metabolic storage, protection

- cutaneous vasculature:

• no direct flow
• 3 intercommunicating plexuses: superficial (dermoepidermal junction), middle (level of sebaceous glands), deep (subQ-dermal junction)
