Study Notes
Integumentary System Overview
- Largest organ, constituting 16% of total body weight.
- Protects against external stimuli and aids in homeostasis.
- Serves as a barrier between the external environment and internal bodily systems.
Skin Structure
- Skin thickness ranges from 0.5 to 6 mm, thicker on the dorsal surfaces of the trunk and limbs.
- Composed of two main layers: epidermis and dermis.
- Epidermis is made of tough stratified squamous epithelium; lacks blood vessels.
- Dermis consists of dense connective tissue with two layers:
- Stratum papillarosum (upper layer, loose connective tissue).
- Stratum reticularosum (deeper layer, dense irregular connective tissue).
Epidermis Functionality
- Protects internal organs from chemicals and microorganisms.
- Regulates body fluid volume and temperature; eliminates waste.
- Contains various cell types:
- Keratinocytes (primary cells).
- Melanocytes (pigment-producing).
- Merkel cells (touch sensation).
- Langerhans cells (immune response).
Dermis Details
- Nerves and blood vessels are abundant, nourishing the epidermis and regulating temperature and blood pressure.
- Blood vessels play a crucial role in homeostasis.
Subcutaneous Tissue
- Comprises loose connective tissue, blood vessels, and adipose cells.
- Attaches the skin to underlying organs, allowing movement over tissues.
- Provides cushioning and protection to bones.
Skin Appendages
- Include hairs, nails, sweat glands, sebaceous glands, mammary glands, and ceruminous glands.
- Develop from embryonic epidermis; play diverse roles in protection and thermoregulation.
Wound Assessment and Measurement
- Volume measurements involve saline injection into wounds for accurate assessment.
- Inspection should include evaluation of hair growth, callus presence, hyperkeratosis, blisters, and scars.
- Color changes, such as to brown or purple, can indicate venous insufficiency.
Skin Flaps in Surgery
- Defined as units of vascularized tissue movable from one body part to another.
- Types include:
- Pedicle flap: Maintains blood vessel continuity.
- Free flap: Blood vessels are detached and reconnected to new vessels.
- Classifications based on vascular supply:
- Random flap: Skin only.
- Axial flap: Follows longitudinal vessels.
- Musculocutaneous flap: Combines skin and muscle vascular supply.
- Fasciocutaneous flap: Vascular supply reaches fascia, providing branches to the skin.
Physical Therapy and Post-Skin Grafting
- Post-operative care plays a crucial role in recovery.
- Ongoing assessment of graft sites and surrounding skin is essential for successful healing.
