Section 1

Question Answer
The thoracic cage
True ribs (1-7)Have there own costal cartilage to connect ribs to cartilage.
False ribs (8-12)cartilage connects to cartilage of rib 7. Floating ribs, not connected to sternum but protect back.
Structure of ribsCurved flat bone, Head articulates with vertebral body, Tubercle articulates with transverse process of vertebra. Costal cartilages articulate with sternum.

Section 2

Question Answer
#Pectoral girdleMade up of the clavical and Scapulae
clavical attached to sternum
scapulaattached to clavicle and humerus

Section 3

Question Answer
Upper Limb- HumerusHead articulates with scapula. Several sites of muscle attachment. Distal condyles (capitulum and trochlea) articulate with forearm, allow hinging of elbow joint.
Forearm bones Radius and Ulna
Radiuslateral (thumb side). Head articulates with humerus, Radial tuberosity attaches biceps brachii, Participates in wrist joint.
Ulnamedial (little finger side) Trochlear notch articulates with humerus, Olecranon forms point of elbow.
PronationRadius rotates at top and crosses over ulna.
Bones of wrist and hands Two rows of carpal bones, metacarpals, proximal phalanges
Carpal bones.Two rows, Proximal row articulate with radius, Distal row articulate with metacarpals.
MetacarpalsSupport palm, Numbered I (thumb) to V
Proximal phalanges (finger bones)articulate with metacarpals, Three phalanges/finger, (Proximal, middle, distal) Two phalanges/thumb (pollex), (Proximal, distal)

Section 4

Question Answer
Lower limbsstructure most important
Pelvislink between vertebral column and lower limbs.The Pelvis Functions: Support, Articulation of leg. Consists of: Os coxae, Sacrum, Coccyx
Coxa is formed by fusion of Ilium, Ischium,Pubis
Features of coxa Iliac crest (hip bones), Ischial tuberosities, Acetabulum (hip joint socket) Symphysis pubis.
Difference of the pelvis in men and womenMen- taller and narrower (90 degrees of less) generally larger and denser, large muscle attachements. Female: lower height, wider (100 degree or more) more spinal curvature, less dense, smaller muscle attachments.

Section 5

Question Answer
# (PICTURES) Parts of the femurHead (angled away from shaft of bone for weight baring), Neck, Greater trochanter (muscles attach- gluteal?), Shaft, Condyles.
Tibiaarticulates with femur.Tibial tuberosity, (Patellar tendon attachment) Anterior crest, Medial malleolus.
FibulaArticulation of head with tibia, Lateral malleolus. Provides stability from the side.
AnkleSeven tarsal bones including: Talus, (Joint with tibia, fibula), Calcaneus (heel bone) (Major load-bearing bone)
Foot(arch shape, allows transfer of forces). Metatarsal bones, (Numbered I to V) Phalanges (toes), (Hallux: Proximal and distal) (Other toes: Proximal, middle and distal)
