01.05 HONORS Bone MarkingsAssignment Directions: Part 1 – Do THREE of the palpation exercises below. Delete the choices you don’t use. Then answer the reflection questions with complete sentences. Part 2 – Complete the chicken wing bone activity and answer the questions. Part 1

Palpation Exercises Choice #1: Patella and Tibial Tuberosity: Sit on a stable surface so that your knees are bent at a 90-degree angle. Use your fingers to feel the front of your kneecap. The patella is a round bone that is suspended in the quadriceps tendon (muscles on the front of your thigh) and patellar tendon. Palpate around all borders. Follow the inferior patellar ligament to the tibial tuberosity. This is the large round projection found at the superior end of your tibia.  Choice #2: Medial and Lateral Condyles of Femur and Tibia: Move your fingers from the patella inferiorly on the medial (and then the lateral) knee surface. You will feel the femoral condyle first, then the tibial condyle. Choice #3: Spine of the Scapula: Facing your partner's back, have him extend his arm out to the side. As the shoulder joint is moved, you should see a spreading of the scapula on the rib cage. With arms extended, palpate the surface of the scapula. There will be an indentation at the superior and inferior halves of the bone. These indentations are the supraspinatous fossa and infraspinatous fossa. You will also be able to feel the horizontal ridge of bone called the scapular spine.

Choice #4: Olecranon Process of the Ulna: With your arm in a relaxed position and enough space for full range of motion, flex and extend the elbow as you palpate its dorsal aspect. Feel the olecranon process of the ulna. This is the large, curved, bony prominence that hooks around the olecranon fossa of the humerus to form the elbow joint.

Choice #5: Surface of the Clavicle: Standing with one of your arms relaxed at your side, palpate the clavicle along its entire length from sternum to shoulder. The clavicle runs horizontally at the upper and anterior part of the thorax, just above the first rib. Although this is a curved bone, you will feel that the surface contains both smooth areas and areas with impressions where muscle attaches.

Choice #6: Lateral and Medial Malleolus: The malleolus is the bony prominence on each side of the ankle. The medial malleolus is the prominent bone on the inner side of the ankle. It is formed by the lower end of the tibia. The lateral malleolus is the prominent bone on the outer side of the ankle. It is formed by the lower end of the fibula.

Questions

1. What structures did you choose to palpate?

2. Were you able to feel the bone markings you were searching for?

3. Which structure was the easiest for you to palpate and which was the most challenging? Why?

Part 2

Chicken Wing Bone Activity

Build a chicken wing by dragging the bones below into formation. Next, build a human arm by dragging the bones into formation. Finally, label the bones and FIVE bone markings in each.
