Anatomy of the Appendicular Skeleton: Pectoral Girdle and Upper Limb Overview

Explore the anatomy of the appendicular skeleton, focusing on the pectoral girdle and upper limb. This section covers key structures such as the clavicle (collarbone) and scapula (shoulder blade), detailing their attachments and functions. Learn about the humerus with features like the greater and lesser tubercles, and the olecranon and coronoid fossae. Understand the radius and ulna in detail, including their articulations and landmarks, such as the radial tuberosity and trochlear notch. Comprehensive diagrams are included for visual reference.

Presentation Transcript

  1. Appendicular Skeleton

  2. Pectoral Girdle • Clavicle – collarbone • Anterior attachment (?) • Posterior attachment (?) • Scapula – shoulder blades • Posterior attachment (?) • Spine – divides posterior surface into 2 sections • Coracoid process (“Corac” = ?) – curves to clavicle • Acromion process – forms tip of shoulder • Glenoid cavity (or fossa) – depression that articulates with head of humerus

  3. Upper Limb Humerus Radius Ulna Carpals Metacarpals Phalanges

  4. Humerus Head fits into glenoid cavity of scapula Greater tubercle – lateral process Lesser tubercle – more anterior process Intertubercular groove – narrow furrow “between tubercles” Deltoid tuberosity – v-shaped, rough area where _________ muscles attach to humerus Olecranon fossa – posterior depression that receives an ulnar process when elbow is straightened Coronoid fossa – anterior depression that receives a radial process when elbow is bent

  5. Radius Shorter bone of lower arm Located on thumb side of arm Disc-like head articulates with humeru and with radial notch of the ulna (so your arm can rotate) Radial tuberosity, a process below the head, provides attachment for biceps Styloid process – at distal end; attachment for wrist ligaments

  6. Ulna • Longer than radius • Overlaps distal end of humerus posteriorly • Proximal end has a wrenchlike opening called the trochlear notch (articulates w/humerus) • Oleacronon process – top process • Coronoid process – bottom process • Radial notch – just below trochlear notch • Head – at distal end; articulates with ulnar notch of radius • Styloid process – attachment for wrist ligaments

  7. Label Diagrams
