The musculoskeletal system consists of all the bones, muscles, tendons, cartilage, joints and ligaments in a person's body. While the bones provide the body’s structure and support, the muscles supply the body’s movement abilities. In middle school you'll learn about the skeleton and about the body’s muscles. Here we cover the two systems combined as they each have to work in unison in order to make the body work.
The skeletal system is divided into two major parts:
Structure of Bones
A bone is enclosed in a protective sheath known as the periosteum which contains blood vessels that help supply nutrients to the bone. Bones are classified into four general categories according to their shape and size as follows:
Another part of the musculoskeletal system includes the joints of the body. There are six major joints as follows:
All muscles perform their work by contracting. Connective tissue covering a muscle tapers into a tough cord called a tendon. Most skeletal muscles are attached to bones by means of tendons. All skeletal muscles are attached at both ends.
The deltoid muscles form the curves of your shoulders and allow you to raise your arms out to the side. Your bicep brachii muscles allow you to bend your arms at the elbow. Your tricep brachii muscle lets you straighten your arms.
The hamstrings are a group of three muscles in the back of your thigh and work together to bend the leg at the knee.
When learning and coming to understand the musculoskeletal system, like many other things in science, there comes a vocabulary list that helps to identify the different parts of the system. Among those vocabulary words, and their meanings, are the following (see below).
If you are thinking of entering into the medical field one day, knowing this information will be invaluable to giving you a head start into your field of study. Even if you do not enter into that field, understanding the skeleton and muscle structure will help you to make wiser choices about what you do to your body and how to keep it healthy.
Building upon your understanding of the human body, below are ten questions on the musculoskeletal system. See if you can challenge yourself to get all the answers correct!
