Name: Craig Nowakowski Section: DL3 Lab Report: Exercise 8: Gross Anatomy of the Muscular System Purpose: The human body contains more than 650 individual muscles which are attached to the skeleton, which provides the pulling power for us to move around. The main job of the muscular system is to provide movement for the body. The muscular system consists of three different types of muscle tissues: skeletal, cardiac, smooth. Each of these different tissues has the ability to contract, which then allows body movements and functions. There are two types of muscles in the system and they are the involuntary muscles, and the voluntary muscles. There are a number of safety cautions when doing a dissection including creating a clean workspace to avoid unnecessary hazards, use gloves to protect your hands from the chemicals and cuts, avoid splash hazards by wearing gloves, and act with caution when using sharp tools. Label the anterior muscles of the body numbered in the diagram.
