Name: Craig Nowakowski Section: DL3 Lab Report: Exercise 5: The Axial & Appendicular Skeleton Purpose: The skeleton is the flexible, bony framework foun d in all vertebrate animals. The skeleton maintains a body shape, protects vital organs, and provides a system of muscle levers that allow body movement. The skeleton contains bone marrow, the blood-forming tissues of the body. Bone marrow stores needed minerals such as calcium and phosphorus and releases them into the blood. A human skeleton generally forms about 206 separate bones out of cartilage as it develops to maturity. Bones are connected to adjacent bones by joints. Joints are either movable as in the arm and leg or immovable as in the skull. In this lab we will use our lab resources to gain a better understanding of the Axial and Appendicular skeletal systems. This lab requires basic safety precautions including a clean work station. Activity 1: The Skull Questions: A. Name the eight bones of the cranium. 2 Parietal Bones, 2 Temporal Bones, 1 Frontal Bone, 1 Ethmoid Bone, 1 Occipital Bone, 1 Sphenoid Bone B. What function do the cranial bones serve?

The main function of the skull is to protect our soft, fragile brains. It also helps to attach the brain and other head organs to the rest of the body by connecting to the spinal cord. Additionally, it contains the bones of the face, which help to form our appearance, and holding our teeth in place.
