    Study Notes

    Scapula

    • The scapula has a supraspinatus fossa and an infraspinatus fossa.
    • The acromion process, spine, and coracoid process are notable features of the scapula.

    Humerus

    • The humerus has a head, anatomical neck, and greater tuberosity.
    • The humerus also has a medial epicondyle, lateral epicondyle, and a trochlea.

    Radius and Ulna

    • The radius and ulna make up the forearm.
    • The radius has a head, neck, and radial fossa.
    • The ulna has a coronoid process, trochlear notch, and olecranon fossa.

    Carpals

    • The carpals include the lunate, scaphoid, triquetrium, trapezium, hamate, and capitate bones.

    Metacarpals and Phalanges

    • The metacarpals are connected to the carpals.
    • The phalanges include the proximal, middle, and distal phalanges.

    Muscles

    • The supraspinatus, infraspinatus, and teres minor muscles are located in the shoulder.
    • The subscapularis, deltoid, and teres major muscles are also important in the shoulder and arm.
    • The biceps brachii, brachialis, and triceps muscles are located in the arm.

    Ligaments and Joints

    • The acromioclavicular joint connects the clavicle and scapula.
    • The glenohumeral joint connects the humerus and scapula.
    • The interosseous membrane connects the radius and ulna.
    • The radial collateral ligament and ulnar collateral ligament stabilize the wrist.

    Nerves and Blood Vessels

    • The radial, ulnar, and median nerves are important nerves in the arm.
    • The brachial artery and radial artery are major blood vessels in the arm.
    • The cephalic vein and basilic vein are important veins in the arm.
