Muscular System Practice Sheet

Introduction

The muscular system is an important part of the human body. It is made up of muscles, tendons, and ligaments that work together to allow us to move. In this practice sheet, we will explore the different parts of the muscular system and how they work together.

Muscles

The muscles of the body are divided into three types: skeletal, smooth, and cardiac.

Skeletal Muscles

Skeletal muscles are the muscles that are attached to the bones. They are responsible for voluntary movement, such as walking, running, and lifting.

Smooth Muscles

Smooth muscles are found in the walls of organs, such as the stomach and intestines. They are responsible for involuntary movements, such as digestion and circulation.

Cardiac Muscles

Cardiac muscles are found in the walls of the heart. They are responsible for pumping blood throughout the body.

Tendons and Ligaments

Tendons and ligaments are connective tissues that attach muscles to bones. Tendons attach muscles to bones and ligaments attach bones to other bones.
