Exercise 8 Review Sheet The Appendicular Skeleton

12/2/21, 12:01 AM Lab 8 Assignment Lab 8 Assignment Due: 11:59pm on Monday, October 11, 2021 Exercise 8 Review Sheet: The Appendicular Skeleton The appendicular skeleton comprises the bones of the upper and lower limbs (the appendages). Each upper limb includes a clavicle and scapula (1/2 pectoral girdle) and the bones of the arm, forearm, wrist, and hand. Each lower limb includes a hip bone (1/2 pelvic girdle) and the bones of the thigh, leg, and foot. Notice that the organization of the bones in the upper limb is comparable to those in the lower limb. For example, the arm and thigh each contain one large long bone; the forearm and leg each contain two smaller long bones that are roughly parallel. Despite these similarities, there are important structural and functional differences between the upper and lower limbs. To complete this Review Sheet, please complete the questions and activities below. Part A - Questions 1-5 Identify the following bone markings by palpating (feeling through the skin) them on yourself or your lab partner. Select your answers from the following list. Answers may be used once or not at all. Drag the appropriate labels to their respective targets. ANSWER: Reset Lesser tubercle Help The prominent bony ridge that you can palpate across the posterior surface of the scapula is the Scapular spine . Place your index finger on the manubrium of your sternum and move it laterally in either direction along Head of humerus Coracoid process the S-shaped path of the clavicle. The lateral end of the clavicle articulates with the Acromion of the scapula. Near the elbow joint, use your thumb and index finger to palpate the Medial epicondyle and Lateral epicondyle , the two prominent projections at the distal end of the humerus. With your forearm extended, identify a shallow depression on the posterior surface of the elbow. The hard surface that you can feel within this depression is the Olecranon fossa . Styloid process of the radius Greater tubercle Near the wrist joint, palpate the small projection at the distal end of the ulna. This projection is the Styloid process of ulna . Radial head Correct Part B - Questions 6-16, part 1 Label the bone markings in the diagram. Drag the appropriate labels to their respective targets. ANSWER: 1/63 12/2/21, 12:01 AM Lab 8 Assignment Supraspinous fossa Reset Help Reset Help Scapular spine Acromion Head of humerus Greater tubercle Anatomical neck Infraspinous fossa Correct Part C - Questions 6-16, part 2 Label the bone markings in the diagram. Drag the appropriate labels to their respective targets. ANSWER: Coracoid process Acromion Head of humerus Greater tubercle Intertubercular groove Lesser tubercle Subscapular fossa Correct Part D - Questions 17-25 Label the bone markings in the diagram. Drag the appropriate labels to their respective targets. 2/63 12/2/21, 12:01 AM Lab 8 Assignment ANSWER: Reset Help Trochlea Capitulum Medial epicondyle Head of radius Lateral epicondyle Olecranon Radial tuberosity Styloid process of radius Styloid process of ulna Correct Part E - Question 26-33 Match the body regions with the bones that are found in that region. Some questions have more than one answer. ANSWER: Reset Help Pectoral Girdle Clavicle, Scapula Arm Humerus Forearm Radius, Ulna Wrist and hand Metacarpal bones, Hamate, Triquetrum Pelvic girdle Ilium, Pubis Thigh Femur Leg Fibula, Tibia Foot Calcaneus, Cuboid Correct Part F Identify the following bone markings by palpating them on yourself or your lab partner. Select your answers from the following list. Answers may be used once or not at all. ANSWER: 3/63 12/2/21, 12:01 AM Lab 8 Assignment Reset Help Press gently with your fingers along your waistline to feel the Iliac crest , which forms the superior border of the bony pelvis. While standing, palpate the shallow depression on the posterolateral aspect of your buttock. From this position, move your fingers anteriorly to feel the Greater trochanter , the massive process that projects laterally from the proximal femur. Patella Sit in a chair and lift up slightly on one side. The Ischial tuberosity can be felt along the inferior margin of the buttock. Sit in a chair and place one hand over your knee and use your fingers to feel the Medial condyle and Lateral condyle of the femur on each side. As you are doing so, the palm of your hand is in contact with the Patellar surface , which rests on the anterior surface of the knee joint. Head of the fibula Lesser trochanter Feel the prominent bump on the anterior surface of the tibia slightly inferior to the knee. This bump is the Tibial tuberosity , which marks the point of attachment for the patellar ligament. At the distal end of the leg, palpate the two prominent bumps on either side of the ankle. These projections are the Medial malleolus of the tibia and the Lateral malleolus of the fibula. Correct Part G - Questions 40-51, part 1 Label the bone markings in the diagram. Drag the appropriate labels to their respective targets. ANSWER: Reset Help Iliac crest Anterior superior iliac spine Posterior inferior iliac spine Anterior inferior iliac spine Greater sciatic notch Acetabulum Lesser sciatic notch Obturator foramen Ischial tuberosity Correct 4/63 12/2/21, 12:01 AM Lab 8 Assignment Part H - Questions 40-51, part 2 Label the bone markings in this anterior-view diagram. Drag the appropriate labels to their respective targets. ANSWER: Reset Help Reset Help Iliac crest Anterior superior iliac spine Auricular surface Anterior inferior iliac spine Ischial spine Pubic tubercle Obturator foramen Correct Part I - Questions 52-64, part 1 Label the bone markings in this anterior-view diagram. Drag the appropriate labels to their respective targets. ANSWER: Neck Greater trochanter Femoral head Lesser trochanter Lateral epicondyle Medial epicondyle Patellar surface Correct 5/63 12/2/21, 12:01 AM Lab 8 Assignment Part J - Questions 52-64, part 2 Label the bone markings in this anterior-view diagram. ANSWER: Lateral tibial condyle Reset Help Reset Help Medial tibial condyle Head of fibula Tibial tuberosity Lateral malleolus Medial malleolus Correct Part K - Question 65 Label the bones in the diagram. Labels may be used more than once. Drag the appropriate labels to their respective targets. ANSWER: Phalanges Phalanges Phalanges Phalanges Cuboid Phalanges Metatarsals Metatarsals Phalanges Talus Cuneiforms Navicular Navicular Cuboid Calcaneus Cuneiforms Talus Calcaneus Correct 6/63
