    Study Notes

    Clavicle Anatomy and Classification

    • The clavicle is classified as a long bone.
    • The medial end of the clavicle is termed the sternal extremity.
    • The lateral end is referred to as the acromial extremity.

    Articulations and Anatomy

    • The lateral end of the clavicle connects with part of the scapula.
    • The medial end of the clavicle articulates with the manubrium.
    • The clavicle is positioned just above the first rib.

    Joint Classifications

    • The sternoclavicular and acromioclavicular joints are classified as synovial joints.
    • Both joints primarily function as gliding joints.

    Gender Differences

    • Males typically have more sharply curved clavicles compared to females.

    Scapula Features

    • The anterior aspect of the scapula is known as the costal surface.
    • A deep depression on the superior border is called the scapular notch.
    • The spine is a large protrusion on the dorsal surface of the scapula.
    • The lateral extension of the scapular spine forms the acromion.
    • The glenoid cavity is a large fossa found at the lateral angle of the scapula.

    Scapular Borders and Angles

    • The superior border extends from the superior angle to the coracoid process.
    • The superior angles are located at the junction of the medial and superior borders.
    • The inferior angle is where the medial and lateral borders meet.

    Fossae of the Scapula

    • The costal surface shows a large depression called the subscapular fossa.
    • The supraspinous fossa is above the scapular spine on the dorsal surface.
    • The infraspinous fossa is a broad area beneath the spine on the dorsal surface.

    Tubercle and Neck Anatomy

    • The coracoid process is a slender, finger-like projection from the lateral angle.
    • The intertubercular (bicipital) groove is a deep depression separating the two tubercles.
    • The anatomic neck is the narrow constriction superior to the tubercles.
    • The surgical neck is a constriction inferior to the tubercles.

    Humerus Characteristics

    • The greater tubercle is a bony process on the lateral surface of the humerus.
    • The head of the humerus is a large rounded eminence that articulates with the glenoid cavity.
    • The lesser tubercle is situated on the anterior surface of the shaft, inferior to the anatomic neck.

    General Shoulder Girdle Anatomy

    • The inferior angle is the most distal angle of the shoulder girdle.
    • The acromion forms part of the scapular spinal process.
    • The scapula is the posterior bone of the shoulder girdle, articulating with the humerus.

    Joint Types and Relationships

    • The scapulohumeral joint is a ball-and-socket type joint.
    • The scapular borders include medial, lateral, and the superior border at the top.

    Bone Classifications

    • The humerus and clavicle are classified as long bones.
    • The scapula is categorized as a flat bone.

    Bursa and Bone Density Conditions

    • Osteoporosis is defined as a loss of bone density.
    • Bursitis refers to inflammation of the bursa.
