15 Appendicular Skeleton- Consists of:
Pectoral girdle & arms Pelvic girdle & legs

16 Upper Pectoral Clavicle - “collarbone”
Functions: attachment point for muscles, brace to hold the arm laterally, transmits compression to axial skeleton

17

18 Clavicle Curve- guarantees the break is not against any blood vessels

19 Clavicle Medially articulates with manubrium (top part of sternum)
Laterally articulates with the scapula at the acromial process

20 Scapulae “Shoulder blade” Lies on the dorsal surface of the rib cage

21

22 Scapulae markings Posterior Spine
Acromion process- end of the spine that connects to the clavicle “point of shoulder” Anterior Coracoid process-”bent little finger” anchors biceps Suprascapular notch- nerve passage

23 Scapulae markings Lateral
Glenoid cavity- a shallow socket that receives the head of the humerus Advantage= the shoulder is flexible because it is a loose attachment Disadvantage= makes it unstable and easy to dislocate

24 Humerus Proximal: Shaft:
Head Greater tubercle and Lesser tubercle-muscle attachment Shaft: Anterior- Deltoid Tuberosity - muscle Posterior- Radial Groove – radial nerve

25

26 Distal Humerus -Trochlea- looks like a spool
-Capitulum- lateral, “ball like” -Coronoid Fossa- anterior depression above the trochlea -Olecranon Fossa- posterior depression above the trochlea -Medial and lateral epicondyles=muscle attachments

27 Lower arm- 2 bones Radius- Lateral (thumb side)
head- proximal meets capitulum styloid process- distal lateral bump

28

29 Lower arm Ulna- medial (pinky side) “wrench” olecranon process
trochlear notch coronoid process Hooks onto the trochlea of the humerus

30 Hand Carpus- wrist (8 bones) Lateral to medial- two rows of 4
Scaphoid Trapezium Lunate Trapezoid Triquetral Capitate Pisiform Hamate “Sally left the party to take Cathy home”

31

32 Hand Metacarpals- 1 -5 Palm to knuckles lateral to medial

33 Phalanges- (14) fingers and thumb Fingers- 3 bones
Hand Phalanges- (14) fingers and thumb Fingers- 3 bones -proximal, middle, distal Thumb- (pollex) 2 -proximal, distal

34 Secured by the strongest ligaments in the body Stable
Pelvic Girdle Functions: attaches lower limbs, transmits weight, supports visceral organs Secured by the strongest ligaments in the body Stable

35 Hip Hip = “ os coxae” -2 coxal bones made of three fused bones

36

37 Hip Fused bones: Ilium Point Ischium of = Acetabulum Fusion Pubis

38

39 Hip Acetabulum = “Hip Socket”

40 Ilium- large flaring bone
Iliac Crest -wings -Anterior Superior Iliac Spine- end of the anterior supeior iliac crest -Posterior Superior Iliac Spine- end of the posterior superior iliac crest

41 Ilium Greater sciatic Notch- posterior deep indentation where the thick cord like sciatic nerve enters the thigh Auricular Surface- medial rough area that articulates with the sacrum

42

43 Ischium –posterior inferior
Lesser sciatic notch- nerves & blood vessels pass to anal and genital area Ischial spine- attaches ligament Ischial tuberosity- buttocks, strong when you sit, it holds your weight

44 Pubis – anterior Obturator foramen- for blood vessels, covered in membrane Pubic symphysis- joint Pubic arch/angle- distinguish males and females

45 Female Pelvis True pelvis- important for childbirth
Ischial spine is shorter Pelvis is shallower, lighter Pubic angle is greater Pubic arch is more round Iliums flare more laterally Inlet is larger and rounded

46

47 Abnormality Dysplasia- the acetabulum is shallow and the head of the femur will slip out

48 Femur- Thigh Largest, longest, strongest bone Head
Fovea Capitas- attachment of a small ligament that secures the bone into the socket – looks like a small pit on the top center of the head Neck –weakest area prone to fracture (broken hip)

49 Femur- proximal Greater Trochanter- lateral Lesser Trochanter – medial
Both are the site of thigh and buttocks muscles Gluteal tuberosity-muscle attachment

50

51 Distal Femur- posterior
Lateral and medial condyles-articulates with the tibia Intercondylar Notch- “U” shaped between condyles Lateral Epicondyles- superior to condyles Medial Epicondyles

52 Tibia Proximal: Medial and lateral condyles articulates with the femur Intercondylar Eminence = point between condyles Tibial tuberosity- anterior attaches patellar ligament

53 Shaft: is wider posterior than anterior (shin)
Distal: articulates with talus of foot Medial malleolus- inner medial ankle

54

55 Fibula Only stabilizes the ankle
Thinner bone in the shin, on the lateral side proximal = Head distal = Lateral Malleolus – lateral ankle

56 Foot Tarsus, Metatarsus, Phalanges
Function: Support, lever to propel weight forward

57

58 Tarsus= 7 tarsal bones 1. Talus- articulates with tibia and fibula 2. Calcaneus- heel bone -Calcaneal = Achilles Tendon -Calcaneal Tuberosity- part that touches ground 3. Cuboid- lateral 4. Navicular- medial 5, 6, 7. Cuniform-medial, intermediate, lateral

59 Metatarsus- 5 (I to V) Starting medial with big toe (I)
Enlarged distal head forms the “ball of the foot”

60 Phalanges (Toes) 14 Big toe – 2 parts proximal and distal
Toe 2,3,4,5 – 3 parts: proximal, middle, distal

61 Arches Maintained by ligaments and tendons 3 arches:
Medial longitudinal Lateral longitudinal Transverse
