Compartment Syndrome - Make it stand out Image: Muscles of the limb are enclosed within rigid fascial compartments that limit expansion. When swelling or bleeding occurs within a compartment, pressure rises, compressing blood vessels and reducing tissue perfusion. This restricted space is what underlies compartment syndrome, where increasing pressure can lead to ischaemia and tissue damage if not relieved. https://www.thenursebrain.com.au/musculoskeletal-pathophysiology/neck-of-femur-fracture monthly 0.5 2026-04-26 https://images.squarespace-cdn.com/content/v1/68c89e20fd3df4642845fa69/005a87de-7495-4a1d-bd43-0b87841517e4/Femur.png Musculoskeletal Pathophysiology - Neck of Femur (NOF) Fractures - Make it stand out Image: The neck of femur is the narrow region between the femoral head and shaft, sitting within the hip joint where the head articulates with the acetabulum of the pelvis.

These differences reflect their underlying behaviour, with BCC rarely metastasising and SCC carrying a greater risk of local destruction and spread. https://images.squarespace-cdn.com/content/v1/68c89e20fd3df4642845fa69/9341f862-1818-469a-9243-309e88dcbec0/Melanocytes.png Integumentary Pathophysiology - Skin Cancer: Basal Cell Carcinoma, Squamous Cell Carcinoma & Melanoma - Make it stand out Image: Melanocytes reside in the basal layer of the epidermis and produce melanin, which is transferred to surrounding keratinocytes.
