- Vascular and nerve supply follow tissue-specific principles, shown here for skin, bone, synovial joints and skeletal muscle.
Blood and Nerve Supply of the Skin
- Epidermis is avascular; dermal vessels supply glands, hair follicles and the metabolically active stratum basale.
- Skin has numerous arteriovenous anastomoses regulating capillary blood flow, helping maintain body temperature.
- Nerve supply: autonomic motor fibres control glands and blood flow; somatic sensory fibres carry cutaneous sensations.
