Appendicular Skeleton: Pectoral Girdle and Upper Extremeties

Pectoral Girdle
a skeletal support to which the forelimbs of vertebrates are attached
-mainly a floating bone. mostly attached to muscles
for shoulder movement
Brachium (Humerus)
The part of the upper arm or forelimb extending from the shoulder to the elbow. (Humerus)
Antebrachium (radius & ulna)
from the wrist to elbow, forearm (radius and ulna)
-the inner and longer of the two bones of the human forearm
-articulates w/ carpal bones
the outer and slightly shorter of the two bones of the human forearm
-articulates w/ humerus
the wrist bone with a rounded head shape that articulates with the 3rd metatarsal
a joint between the distal end of the radius and the proximal row of carpal bones
Distal Row Carpals
hamate, capitate, trapezoid, trapezium
carpal, moon shaped
Hand bones. 5 bones numbered from 1-5, medial to lateral
finger bones
a small wrist bone that articulates only with the triquetral
Proximal Row Carpals
pisiform, triquetrum, lunate, scaphiod
shaped like a boat
the wrist bone on the thumb side of the hand that articulates with the 1st and 2nd metacarpals
Most ulnar bone of proximal row.
the outermost point of the spine of the shoulder blade
Clavicle Acromial End
flat lateral aspect - articulates w/acromion process of the scapula to form
Acromioclavicular Jt - AC Joint
synovial gliding joint
Clavicle Sternal End
collar bones "S" shaped - long bones
sternal end - medial articulates w/sternum to form Sternoclavicular joint
Corocoid Process
the beak-shaped process of the scapula
Glenoid Fossa
the concavity in the head of the scapula that receives the head of the humerus to form the shoulder joint
Inferior Angle of Scapula
origin of teres major
Infra Glenoid Tubercle
Infraspinous Fossa
Depression below spine of scapula
Lateral Axillary Border of Scapula

Anatomical Neck of Humerus
Intertubercular or Bicipital Groove of Humerus
Body of Humerus
Capitulum of Humerus
Lateral condyle, articulates with Radius
Condyle of Humerus
Coronoid Fossa of Humerus
anterior depression that receives the coronoid process of the ulna when forearm is flexed.
Deltoid Tuberosity of Humerus
insertion of deltoid
Lateral Epicondyle of Humerus
Medial Epicondyle of Humerus
Greater Tubercle of Humerus
Head of Humerus
Lesser Tubercle of Humerus
what is the insertion of the subscapularis
Olecranon Fossa of Humerus
Posterior Depression on Humerus which receives the olecranon process of the ulna when the forearm is extended(straightened).
Radial Fossa of Humerus
light anterior depression, sueprior to capitulum; receives anterior border of head of radius when forearm is fully flexed
Radial Groove of Humerus
Slight groove under deltoid tuberosity.
Supracondylar Ridges of Humerus
Surgical Neck of Humerus
Trochlea of Humerus
a smooth, grooved articular process shaped like a pulley on a bone
