Chapter 8 Flashcards
Pectoral girdles
2 of them
Attach bones of the upper limb to the axial skeleton
Clavicle
Collarbone
S shaped
Rougher and more curved in males
Sternal end
Medial end of clavicle
Articulates with manubrium to form sternoclavicular joint
Acromial end
Broad, flat, lateral end of clavicle
Articulates with acromion of scapula and forms acromioclavicular joint
Scapula
Shoulder blade
Large triangular flat bone
Acromion
Lateral end of the prominent ridge (called spine) projects as a flattened, expanded process
Glenoid cavity
Shallow depression that accepts the head of the humerus to form glenohumeral joint
Upper limb
Has 30 bones split between
Humerus
Ulna and radius
Carpals
Metacarpals
Phalanges
Humerus
Arm bone
Longest and largest bone of upper limb
Greater tubercle
Lateral projection distal to anatomical neck
Most laterally palpable bony landmark of shoulder region
Deltoid tuberosity
Roughened v shaped area at middle portion of shaft of humerus
Point if attachment for deltoids
Trochlea
Spool shaped surface that articulates with trochlear notch of ulna
Coronoid fossa
Anterior depression that takes the coronoid process of the ulna when forearm is flexed
Olecranon fossa
Large posterior depression that receives the ulna when forearm is extended
Medial and lateral epicondyle
Rough projections on either side of distal end of humerus
Tendons of must forearm muscles attach
Ulna
Located on medial aspect (little finger)
Longer than radius
Radius
Smaller bone of forearm located on lateral aspect of foarearm
Carpals
Wrist
Proximal region of the hand and consists of 8 carpals that are joined by ligaments
Carpals
Scaphoid
Lunate
Triquetrum
Pisiform
Trapezium
Trapezoid
Capitate
Hamate
Metacarpals
Palm
Intermediate region of the hand and consists of 5 bones called metacarpals
Phalanges
Bones of the digits
Make up distal part of hand
14 in each hand
Pelvic Girdle
Consists of two hip bones/coxal/pelvic bones/os coxa
