CUTANEOUS BLOOD SUPPLY

Function:

  - metabolic and nutrient needs

  -aid in thermoregulation of body

PATTERN OF BLOOD FLOW

From deep arteries via perforator arteries to vascular network known as ‘plexus'

Plexuses:

Subdermal

Dermal

Subpapillary

Terminal capillary

Lymph vessels

Associated with the vascular plexuses

Thermoregulation

  - Arteriovenous anastomoses

  - Glomus body

   -Afferent
• Somatic
• Autonomic
o Sympathetic
o Parasympathetic
    -Efferent

Sensory receptors
-afferent nerve fibres

CUTANEOUS SENSATION
