Pectoral Girdle

a skeletal support to which the forelimbs of vertebrates are attached

Scapula

-mainly a floating bone. mostly attached to muscles

Clavicle

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)

Ulna

-the inner and longer of the two bones of the human forearm
-articulates w/ carpal bones

Radius

the outer and slightly shorter of the two bones of the human forearm
-articulates w/ humerus

Capitate

the wrist bone with a rounded head shape that articulates with the 3rd metatarsal

Carpus

a joint between the distal end of the radius and the proximal row of carpal bones

Digits

Fingers

Distal Row Carpals

hamate, capitate, trapezoid, trapezium

Lunate

carpal, moon shaped

Manus

HAND

Metacarpals

Hand bones. 5 bones numbered from 1-5, medial to lateral

Phalanges

finger bones

Pisiform

a small wrist bone that articulates only with the triquetral

Proximal Row Carpals

pisiform, triquetrum, lunate, scaphiod

Scaphoid

shaped like a boat

Trapezium

the wrist bone on the thumb side of the hand that articulates with the 1st and 2nd metacarpals

Triquetrum

Most ulnar bone of proximal row.

Acromion

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

Medial Ventral Border of Scapula

Spine of Scapula

Subscapular Fossa

Superior Angle of Scapula

Superior Border of Scapula

Supraglenoid Tubercle

Suprascapular Notch

Supraspinous Process

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

Body of Radius

Carpal Articular Surface of Radius

Head of Radius

Neck of Radius

Radial Tuberosity of Radius

Styloid Process of Radius

Ulnar Notch of Radius

Body of Ulna

Coronoid Process of Ulna

Head of Ulna

Olecranon Process of Ulna

Radial Notch of Ulna

Styloid Process of Ulna

Trochlear Notch of Ulna

Ulnar Tuberosity

Body of Sternum

Base of Metacarpal

Body of Metacarpal

Head of Metacarpal

Jugular Notch of Sternum

Acromion Process

Corocoid Process

Xiphoid Process of Sternum
