Study Notes
Deep Fascia
- Deep fascia is a membrane of fibrous tissue wrapping limbs and body walls.
- Thickness varies greatly. Examples include the thick iliotibial tract and thin rectus sheath.
- Absent in some areas like face and ischioanal fossa.
- Always firmly anchored to periosteum, never free over bone.
Subcutaneous Tissue
- Connects skin to underlying bones or deep fascia.
- Composed of areolar tissue with varying characteristics across species.
- Important for anchoring and separating structures and tissues.
Synovial Sheaths
- Surround tendons subjected to heavy stress with adjacent structures or direction changes
- Contains two layers: parietal (attached to surrounding structures) and visceral (attached to tendon). These glide past each other lubricated by synovial fluid.
- Doesn't always completely enclose the tendon cylindrically.
- Allows blood vessels for longitudinal anastomosis to enter
Skin Tension Lines
- Skin creases near joints run parallel to tension lines.
- Wrinkles from age/aging do not perfectly match cleavage lines.
- Incisions along natural lines heal with less scarring.
- Avoid cutting across flexure creases.
Upper Limb Anatomy Details (partial summary)
- Scapula has costal surface (concave), and multiple ridges converging to the lateral angle.
- Acromion projects from scapula's dorsal surface.
- Infraspinous fossa is concave, with a subscapularis muscle originating from its concavity and lateral border.
- Teres minor originates from a dorsal area on the lateral border, with a groove for circumflex scapular vessels.
- Thick fascia covers infraspinatus and teres minor.
- Tendon of biceps brachii enclosed by synovial membrane.
- Bicipital groove on the anterior surface of the upper humerus.
- Greater tuberosity (bare bone) is palpable.
- An intertubercular groove on anterior surface.
- The radius has a tuberosity for supinator, a longitudinal ridge for pronator terer, and a ridge for the interosseous membrane.
- Synovial membrane lines the elbow joint capsule.
- The narrow humeral neck is surrounded by annular ligament.
