Terminology: Anterior / front, posterior / back, medial/middle, lateral/opposite, superior / top. inferior / bottom, proximal / closer to the centre, distal / away from the centre, deep/covered, superficial/visible, subcutaneous / just below the surface. Skeleton System: Skeleton: bone on the surface as landmark, skull, clavicles, spine (atlas, 7 cervical, 12 thoracic, 5 lumber, 2 tail bone), pelvic, anterior superior iliac spine (ASIS), Scapula, Posterior Superior Iliac Spine (PSIS), legs, femur, tibia, fibula, patella, arms, humerus/triangle at the elbow, hands. Human figure proportions. Human figure proportions: Robert Beverly Hale (11.5 cranial), foreshortening agnostic, dynamics of body, width from the front, height from the side. Secondary human figure proportions: Richer (7.5 heads), Loomis (8 heads). Croquis: 9 heads proportions, face, neck, shoulder, chest, waist, pelvic, thigh, calf, ankle, feet, upper arms, forearm, hands, female, male. Croquis dynamics: Front, side, three-quarter and back pose. Human figure structure: Mannequinization, box, cylinder, oval. Human figure types: Male, female and kid. Torso Torso: Rib cage, pelvic, tilt, lean, twist, foreshortening, front, back. Torso front: Pectoralis major, latissimus dorsi, serratus anterior, rectus abdomens. Torso back: Sternocleidomastoid, trapezius, deltoid, infraspinatus, teres minor teres major, rhomboideus major, latissimus dorsi, erector spinae, obliquus externus, scapula. Legs & Arms Arms: Biceps brachii, triceps brachii, extensor capri radialis longus, anconeus. Hands: Construction, muscles/ligaments, bones and nerves. Legs: Construction, muscles/ligaments, bones and nerves. Feet Construction, muscles/ligaments, bones and nerves. Dynamics Synovial joints: Shape, movement, hinge for flexion and extension(elbow), pivot (elbow), ball & socket (hip/shoulder), ellipsoid (wrist), saddle (thumb), plain (hand/foot). Gesture: Rhythm (flow/action/motion/movement), contours, longest axis, CSI lines, line of action, tense vs relaxes, directional flow. Balance: Gravity, point of contact on the ground (single point, two points/line, three points/triangle, four points/quadrangle), weight on point of contacts, the centre of support, weight on point and centre of support, the centre of gravity, distribution of weight and wideness of base, balance is equal mass/weight on either side, weight distribution on legs and external support. Dynamics: Controlled fall or controlled loss of balance, muscle strength against gravity, dynamics of the rib cage, pelvic and spine, contrapposto (stretch/squash, high/low, supporting/extended leg), activities, muscle tension.
