Appendicular skeleton

Pectoral girdle(clavicle + scapular)

* Clavicle - 인체에서 뼈되기가 가장 빠름 - 원뿔인대 존재 - 가장 잘 부러짐 - 양 끝은 acromial end sternal end

Pectoral girdle(clavicle + scapular) * Scapular - spine - supraspinatus fossa - infraspinatus fossa - subscapular fossa - glenoid cavity - angle(3) - border(3)

Upper limb ► * Brachium(arm proper) - humerus * Antebrachium(forearm) - radius + ulna * Carpus(wrist) - carpal bones(8) * Manus(hand) - metacarpals(5) + phalanges(14)

Humerus - 팔에서 가장 긴 뼈 - surgical neck : 골절 빈발 부위 - medial epicondyle : origin of wrist flexor - lateral epicondyle : origin of wrist extensor - tubercle(greater, lesser) - capitulum + trochlea - radial + coronoid fossa

Forearm(radius & ulna) * Radius - head(proximal end) - neck - tuberosity (biceps insertion) - ulnar notch of radius - styloid process * Ulna - trochlear notch - coronoid process - olecranon - tuberosity (brachialis insertion) - radial notch of ulna - head(distal end)

Hand * Carpal bone(8 쌍 ) * Metacarpal bone(5 쌍 ) * Phalanges(14 쌍 ) Radiocarpal joint = radius + scaphoid, lunate, triquetrum

Pelvic girdle * Hip bone + Sacrum

Pelvis 여 성남 성 큰골반좁다넓다 작은골반 ( 진골반 ) 넓고, 얕다좁고, 깊다 두덩밑각 ( 활 ) 크다 (90 도 ↑ ) 작다 (90 도 ↓ ) 두덩결합짧다길다 엉치뼈, 엉덩뼈넓다좁다 위골반문타원형심장형 폐쇄구멍삼각형타원형 * 골반 내장 : 방광, 전립샘, 자궁, 난소, 곧창자 MF

Pelvic girdle * Hip bone = ilium + pubic + ischium - ASIS, AIIS, PSIS, PIIS - iliac crest - obturator foramen (obturator nerve) - gluteal line(3) - acetabulum - auricular surface - pubic symphysis - ischial tuberosity - pubic ramus - ischial ramus

Lower limb ► * Femoral(thigh) - femur + patella * Crural(leg proper) - tibia + fibula * Tarsal(ankle) * Pedal(pes-, foot) - tarsal bones(7) - metatarsals(5) - phalanges(14)

Thigh(femur & patella) * Femur - 인체에서 가장 긴 뼈 - 경체각, 염전각 존재 - neck : 노인에서 골절 빈발 * Patella - 역삼각형 모양 - 인체에서 가장 큰 종자뼈

Leg(tibia & fibula) * Tibia - tibial tuberosity - intercondylar eminence (cruciate ligament 부착부 ) - medial malleolus * Fibula - lateral malleolus

Foot(=pes)

* Arches of the foot - medial longitudinal arch: 목말뼈, 쐐기뼈, 발배뼈, 1,2 발허리뼈 - lateral longitudinal arch: 발꿈치뼈, 입방뼈, 4,5 발허리뼈 - transverse arch:1,2,3 쐐기뼈, 입방뼈
