Study Notes
Clavicle Function
- Provides stability and attachment points for muscles in the shoulder joint
Scapula Articulation
- The glenoid cavity of the scapula articulates with the humerus.
Clavicle Inferior Face
- The costoclavicular ligament and subclavius muscle attach to the inferior face of the clavicle.
Radius Articulation
- The humerus does not articulate with the radius.
Biceps Brachii Insertion
- The biceps brachii muscle inserts on the radial tuberosity of the radius.
Ulna Features
- The olecranon process, coronoid process, and trochlear notch are found on the ulna.
Interosseous Membrane Function
- The interosseous membrane provides stability and transmits forces between the radius and ulna.
Carpal Bones
- The carpal bones are arranged in two rows, with the proximal row articulating with the radius and ulna.
Clavicle Shape
- The clavicle has an "S" shape.
Clavicle Articulations
- The clavicle articulates with the sternum (at the sternoclavicular joint) and the scapula (at the acromioclavicular joint).
Clavicle Parts
- The clavicle consists of a medial (sternal) end, a lateral (acromial) end, and a body.
Conoid Tubercle Insertion
- The conoid ligament, part of the coracoclavicular ligament, inserts into the conoid tubercle of the clavicle.
Subclavius Muscle Location
- The subclavius muscle is located on the inferior surface of the clavicle.
Scapula Shape
- The scapula is triangular in shape.
Scapula Articulations
- The scapula articulates with the humerus (at the glenohumeral joint) and the clavicle (at the acromioclavicular joint).
Scapula Fossa
- The subscapular fossa is located on the costal face of the scapula.
Humerus Surgical Neck
- The surgical neck of the humerus is the constricted area just below the head and greater and lesser tubercles.
Radial Tuberosity Association
- The radial tuberosity serves as the insertion point for the biceps brachii muscle.
Sternum Composition
- The sternum is composed of bone and cartilage.
Sternum Largest Part
- The body is the largest part of the sternum.
Carpal Bones Number
- The human hand has eight carpal bones.
Proximal Carpal Bones
- The proximal row of carpal bones, from lateral to medial, includes the scaphoid, lunate, triquetrum, and pisiform.
