CLAVICLE Lateral End / Acromial End Flat Two surfaces Two borders Medial End / Sternal End Quadrilateral Four surfaces Shaft (Lateral and Medial) Curved Concave Forward: Lateral 1/3 part Convex Forward: Medial 2/3 part Inferior Surface Ridge → Trapezoid Ridge (Lateral Side) Elevation → Conoid Tubercle (Lateral Side) Groove → Sub-Clavian Groove (Medial Side) Impression → Costal Tuberosity (Medial Side) Lateral Shaft → 1/3 Borders Anterior (Concave) → Deltoid Posterior (Convex) → Trapezius Surfaces Superior → Subcutaneous Inferior Elevation → Conoid Tubercle Ridge → Trapezoid Ridge Medial Shaft → 2/3 Four Surfaces ANT (Convex Forward) → Pectoralis Major Muscle POST → Sterno Hyoid Muscle SUP → Sterno Cleido Mastoid Muscle INF → Subclavius Muscle CARPAL BONES The carpus is made up of 8 carpal bones, which are arranged in two rows. Proximal Row (from lateral to medial side): Scaphoid Lunate Triquetral Pisiform Distal Row (from lateral to medial side): Trapezium Trapezoid Capitate Hamate Scaphoid Boat-shaped and has a tubercle on its lateral side. Lunate Half-moon shaped or crescentic. A small semilunar articular surface for the scaphoid on the lateral side. A quadrilateral articular surface for the triquetral on the medial side. Triquetral Pyramidal shape. Oval facet on the distal part of the palmar surface. Oval facet for the pisiform lies on the distal part of the palmar surface. Medial and dorsal surfaces are continuous and non-articular.
