Name_______________________________Year/Section_______________Date___________ Skeletal System Laboratory Activity Objectives: At the end of this activity, the students will be able to:  Identify the bones and classify the bones according to shape.  Differentiate the three types of joints.  Discuss the types of fracture.  Define the different types of body movements. Bones are organs composed of a complex arrangement of several tissues. A typical bone has compact and spongy osseous tissues, cartilage, adipose tissue, blood cells and connective tissue membranes. There are 206 named bones in the adult skeleton, which can be separated into axial and appendicular divisions. The word skeleton comes from a Greek word skeletos which means “dried- up body.” The appendicular skeleton (appendere = to hang upon) is composed of 126 bones that make up the upper limbs, and the bones of the girdles that attach the limbs to the axial skeleton. The axial skeleton includes the skull, hyoid bone, vertebral column, and thoracic cage (rib cage). Smaller bones included in this division are the ear ossicles (bones). Activity: I. Classify the bones according to shape and give one example for each. (8 points) II. Enumerate the three types of joint and indicate whether the articulation is immovable, slightly movable or very movable. (6 points) A.
