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.
