Lab 16- Pectoral Girdle and Upper Limb(test 2) Flashcards
Clavicle
sternal (medial) end- articulates with the manubrium of the sternum
acromial (lateral) end- articulates with the acromion of the scapula
scapula
spine acromion- lateral end of spine glenoid cavity- shallow socket; articulates with head of humerus coracoid process- beadlike projection superior border medial (vertebral) border lateral (axillary) border Fossa-shallow depressions *supraspinous fossa *infraspinous fossa *subscapular fossa superior angle inferior angle supraglenoid tubercle infraglenoid tubercle
humerus
proximal features
*head-articulates with glenoid cavity
*greater tubercle- on lateral side
*lesser tubercle- on anterior side
*anatomical neck- tapered region near head
*surgical neck- common fracture site
*intertubercular sulcus- furrow for tendon of biceps muscle
shaft
*deltoid tuberosity
distal features
*capitulum- lateral condyle; articulates with radius
*trochlea- medial condyle; articulates with ulna
*medial epicondyle
*lateral epicondyle
*coronoid fossa- articulates with coronoid process of ulna
*olecranon fossa- articulates with olecranon process of ulna
radius
lateral bone of forearm
- head of radius-allows for rotation at elbow
- radial tuberosity
- styloid process of radius
- ulnar notch of radius- articulation site with ulna
ulna
medial bone in forearm; longer than radius
- trochlear notch
- radial notch of ulna- articulation site with head of radius
- olecranon process
- coronoid process
- styloid process of ulna
- head of ulna- at distal end
carpal bones
positioned in two irregular rows Proximal-listed lateral to medial *Scaphoid *Lunate *Triquetrum *Pisiform Distal-listed medial to lateral *Hamate *Capitate *Trapezoid *Trapezium
metacarpals
1-4
phalanges
located in digits
- proximal phalanx
- middle phalanx(not present in thumb)
- distal phalanx
