Study the anatomy of the back muscle with the aid of the following back muscle diagrams. We have a selection of back muscle pictures that you can use as the reference in studying the back anatomy which includes some of the most massive and functionally important muscles in the human body. Check out the muscle diagram of the back in the following images below. Click to see the full size and download!
You can observe in the back muscle diagram that we provided in this page that back muscles are divided into two specific groups: the extrinsic muscles that are associated with upper extremity and shoulder movement, and the intrinsic muscles that deal with movements of the vertebral column. In brief, the back anatomy includes the latissimus dorsi, trapezius, erector spinae, rhomboid, and the teres major. Learn more about each of these muscles and their locations in the following muscle diagrams.
The latissimus dorsi is the largest and most well-known of all the back muscles. The trapezius muscles are located between the shoulder and neck. Meanwhile, the erector spinae muscles, or spinal erectors, line the spinal column from the lower to the upper back. The rhomboid muscle is located on the upper portion of the back anatomy, underneath the trapezius. They originate from the vertebrae and insert into the scapulae. This muscular system diagram shows the major muscle groups from the back or posterior view.
Triceps brachii is a muscle that straightens the arm. The triceps runs down the back of the upper arm. It straightens or extends, the arm and shoulder. The far end of the muscle is attached by strong a tendon to the ulna, at the point of the elbow. You can save and print this diagram to help you with the study of muscle anatomy.
