HUMAN ANATOMY SKELETAL: APPENDI CULAR SKELETON Appendicula r Skeleton  How many bones is the appendicular skeleton consists of? 126 bones  These bones can be divided into which 2 groups? limb bones girdle bones  Describe the function and provide examples of girdle bones: Girdle bones attach limb bones to the axial skeleton Bones of the shoulder region form the pectoral girdle which attaches the upper limb to the thoracic cage. Pectora l Girdle - Overview *Feel free to only label the parts we cover in lecture. clavicle clavicle scapula scapula Acromial end Sternal end  Pectora l Girdle – Sca pula acromion suprascapular notch superior border coracoid process suprascapular notch coracoid superior angle acromion process supraspinous fossa spine Infraspinous fossa subscapular fossa lateral border lateral border medial border inferior angles General notes & observations:  Upper Limb - Humerus Head greater greater tubercle tubercle anatomical neck lesser tubercle surgical neck Intertubercular groove Deltoid tuberosity body (shaft) Olecranon fossa lateral epicondyle Radial fossa Coronoid fossa Capitulum medial epicondyles trochlea General notes & observations:  Upper Limb – Ra dius & Ulna olecranon process trochlear notch Head head of radius of radius coronoid neck of neck of process radius radius radial proximal tuberosity radioulnar joint Interosseous membrane Ulna Radius Radius Head of ulna distal radioulnar joint styloid process of ulna styloid process of radius  Upper Limb – Wrist & Ha nd proximal middle Phalanges distal proximal distal metacarpal trapezium Hamate trapezoid Capitate trapezium scaphoid pisiform trapezoid triquetrum lunate scaphoid General notes & observations:  Pelvic Girdle - Overview Its job is to attach the legs to the axial skeleton.
