YOUR NAME: LAB SECTION: Human Osteology II – Appendicular Skeleton Objectives: After the lab, you should be able to: ● Identify the major bones of the human body by name, location, and shape. ● Identify the anatomical planes of the body. ● Correctly orient the body in standard anatomical position. ● Describe the types of motion that occur at joints between bones. ● To become familiar with the methods biological and forensic anthropologists use to identify an individual's height and age by looking at skeletal remains. Station 1. The Upper Limb Identify the following elements of the upper limb and hand: clavicle, scapula, humerus, ulna, radius, carpals, metacarpals, and phalanges. Use the articulated skeleton for reference. 1. With which bone does the humerus articulate at the shoulder? 2. With which two bones of the shoulder girdle does the scapula articulate? 3. With which bones does the humerus articulate at the elbow? 4. In standard anatomical position, are the radius and ulna positioned proximal or distal to the humerus? 5. In standard anatomical position, is the radius positioned lateral or medial to the ulna? 6. With which group of bones do the ulna and radius articulate in the wrist? 7. What is the correct osteological name of the bones in the palm of the hand? 1

8. What is the correct osteological name of the bones of the fingers? Station 2. The Lower Limb Identify the following elements of the lower limb: os coxa (which is made up of three separate bones that fuse together, the ilium, pubis, and ischium), femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges). For each element, determine its correct anatomical position. Use the articulated skeleton for reference. 1. With which bone of the os coxa does the sacrum articulate? 2. The femur articulates with which bone at its proximal end? 3. The rounded ball at the proximal end of the femur is called what? 4. The femur articulates with which TWO bones on its distal end? 5. In standard anatomical position, does the patella lie anterior or posterior to the femur? 6. In standard anatomical position, does the tibia lie lateral or medial to the fibula? 7. The tibia and fibula articulate with which group of bones in the ankle? 8. Which bones make up the toes? 9. What bones lie between the phalanges and the tarsals? 2
