    Study Notes

    Applied Anatomy and Palpation

    • Applied anatomy is the application of anatomy knowledge to find anatomy structures.
    • Palpation is a technique used in physical examination to examine parts of the body by touching and feeling them.
    • There are two types of palpation: static palpation and motion palpation.
      • Static palpation is used to feel the alignment and symmetry of the surrounding soft tissue.
      • Motion palpation is used to feel the motion of specific body segments.

    Upper Limb

    • The upper limb is composed of a few bones located at the upper part of the body.
    • It consists of the shoulder, arm, forearm, and hand.
    • The elbow is a complex modified hinge articulation that accommodates flexion, extension, and rotation movements of the forearm.

    Shoulder Girdle

    • The shoulder girdle is composed of three bones: scapula, clavicle, and humerus.
    • It facilitates the placement of the hand in space.
    • The scapula lies flatly on the posterior aspect of the thorax, approximately 45 degrees forward from the midsagittal plane.
    • The glenoid cavity is a shallow socket located at the superolateral corner of the scapula.

    Scapulothoracic Joint

    • The scapulothoracic joint is a nonsynovial articulation.
    • It is composed of the broad, flat, triangular scapula overlying the thoracic cage and separated from the thoracic cage by a large bursa.
    • The plane of the scapula lies 45 degrees forward from the midcoronal plane of the body.

    Palpation of Shoulder Structures

    • Palpation of the suprasternal notch: located at the middle of the thorax, between the two clavicles.
    • Palpation of the sternoclavicular joint: located at the articulation between the sternum and clavicle.
    • Palpation of the clavicle: a bony curved surface that can be palpated laterally from the sternoclavicular joint.
    • Palpation of the shoulder flexor: can be performed with the patient lying on their side or sitting with the arm at the side and the elbow slightly flexed.
    • Palpation of the shoulder extensor: can be performed with the patient prone lying or side lying with the arm upwards.
    • Palpation of the shoulder abductor: can be performed with the patient sitting or supine lying with the arm abducted to 90 degrees.
    • Palpation of the shoulder adductor: can be performed with the patient supine or sitting with the arm abducted to about 90 degrees.

    Testing Shoulder Muscles

    • Testing shoulder flexion: can be performed with the patient sitting or lying on their side with the arm upwards.
      • Resisted test: applying downward resistance as the patient attempts to elevate the arm.
    • Testing shoulder extension: can be performed with the patient prone lying or side lying with the arm upwards.
      • Resisted test: applying downward resistance as the patient attempts to elevate the arm.
    • Testing shoulder abduction: can be performed with the patient sitting or supine lying with the arm abducted to 90 degrees.
      • Resisted test: applying downward resistance as the patient attempts to abduct the arm.
    • Testing shoulder adduction: can be performed with the patient supine or sitting with the arm abducted to about 90 degrees.
      • Resisted test: applying resistance away from the midline of the patient as the patient attempts to adduct the arm.
