    • What is the appendicular skeleton responsible for?
      It is responsible for limb movement and attachment to the axial skeleton.
    • When does the development of the appendicular skeleton begin?
      It begins before birth.
    • At what age does the completion of appendicular skeleton development typically occur?
      Around age 25.
    • What are the main components of a mammalian limb anatomy?
      • Single strong bone close to trunk
      • Hinge joint connecting two distal bones
      • Complex joint made of short bones
      • Hand, foot, or wing made of rows of small bones
    • What bones compose the shoulder girdle?
      The clavicle and scapula compose the shoulder girdle.
    • What is the function of the shoulder girdle?
      It anchors the upper limb to the axial skeleton and facilitates movement.
    • What is another name for the clavicle?
      Collarbone.
    • How is the clavicle described in terms of its structure?
      It is a loosely-anchored, S-shaped bone.
    • With which bone does the clavicle articulate medially?
      Manubrium of the sternum.
    • What joint is formed by the clavicle articulating with the manubrium?
      Sternoclavicular joint.
    • What does the clavicle articulate with laterally?
      Acromion of the scapula.
    • What joint is formed by the clavicle articulating with the acromion?
      Acromioclavicular joint.
    • Where is the scapula located?
      On the posterior of the shoulder.
    • What articulates with the glenoid cavity of the scapula?

      The head of the humerus.
    • What joint is formed by the head of the humerus and the glenoid cavity?
      Glenohumeral joint.
    • What are the processes found on the scapula?
      Coracoid and acromion processes.
    • What are the fossae present on the scapula?
      Supraspinous, infraspinous, and subscapular fossae.
    • What are the three borders of the scapula?
      • Superior border
      • Medial border
      • Lateral border
    • What is the distal end of the humerus responsible for?
      It forms the elbow joint.
    • Which structures articulate with the distal end of the humerus?
      Trochlea articulates with ulna and capitulum articulates with radius.
    • What are the additional bony markings of the humerus?
      Anatomical neck, surgical neck, greater and lesser tubercles, intertubercular groove, medial and lateral epicondyles, and coronoid and radial fossae.
    • What is the ulna's position in the antebrachial region?
      It is the medial bone.
    • What shape does the proximal end of the ulna resemble?

      It resembles the shape of the letter "C".
    • What processes form the trochlear notch of the ulna?
      Olecranon and coronoid processes.
    • With which part of the humerus does the ulna articulate at the elbow?
      Trochlea of the humerus.
    • What type of motion does the ulna allow at the forearm?
      Hinge-like motion.
    • What is the radius's position in the antebrachial region?
      It is the lateral bone.
    • What does the head of the radius articulate with at the elbow?
      Capitulum of the humerus.
    • What motion does the radius allow in relation to the ulna?
      It rotates around the ulna to allow pronation and supination of the forearm.
    • What is found between the radius and ulna?
      Interosseous membrane.
    • What does the distal end of the radius articulate with?
      Carpal bones.
    • What are the eight carpal bones arranged into?
      • Proximal row (lateral to medial): Scaphoid, lunate, triquetrum, pisiform
      • Distal row (lateral to medial): Trapezium, trapezoid, capitate, hamate
    • How many metacarpals are found in the palm of the hand?
      Five metacarpals.
    • How many phalanges are found in the fingers?
      Fourteen phalanges (three in each finger, two in the thumb).
    • How are the phalanges named?
      They are named according to their relative position: proximal, middle, and distal phalanges.
    • How many phalanges does the thumb have?
      Two phalanges (proximal and distal).
    • What are the common causes of fractures in upper limb bones?
      • Breaking a fall
      • Outstretched hand sending force through upper limb
      • Resulting in various types of fractures
    • What are the three fused bones that form the os coxae?
      Ilium, ischium, and pubis.
    • How is the os coxae anchored anteriorly?

      By the pubic symphysis.
    • How is the os coxae anchored posteriorly?
      To the sacrum.
