In this article, I will explain the “sternocleidomastoid muscle” in detail. The sternocleidomastoid muscle is a muscle in the neck and chest that supports head movement and plays an important role in breathing. This article covers a wide range of aspects, including its structure, function, and related physical disorders and effects on exercise. We aim for readers to have a deep understanding of the function and importance of sternocleidomastoid muscle, and we provide information that can be used as a reference in daily life and during exercise.
Please use this article to deepen your understanding of the body.

What is sternocleidomastoid muscle
The sternocleidomastoid muscle is one of the important muscles in the human body from the neck to the chest. This muscle, which controls neck movements and is also involved in breathing, is frequently used in everyday life. In the human anatomy diagram, it is depicted as a muscle that runs diagonally from the front of the neck to the shoulder.
How to read sternocleidomastoid muscle
The sternocleidomastoid muscle is read as “you can do it right now.” This name is a combination of words representing the beginning and stopping part of this muscle.
Characteristics of sternocleidomastoid muscle
The sternocleidomastoid muscle works when the neck is tilted forward or rotated sideways. Also, when taking a deep breath, it also works to help breathing by lifting the ribs.
Location and position of sternocleidomastoid muscle

If you look closely using a human anatomy chart, the sternocleidomastoid muscle is located on the side and front of the neck, and at the top of the chest. Specifically, it starts at the sternal end of the collarbone and extends to the mastoid area below the ear.
How to remember sternocleidomastoid muscle
When learning sternocleidomastoid muscle, it's a good idea to imagine it as “the muscle that connects the neck to the chest.” Also, be sure to visually check how the sternocleidomastoid muscle runs while looking at the human anatomy diagram.
English/Latin for sternocleidomastoid muscle
The sternocleidomastoid muscle is expressed as Sternocleidomastoid muscle in English and Musculus sternocleidomastoideus in Latin. These names are also a combination of words indicating the beginning and end of a muscle.
Trivia about sternocleidomastoid muscle
The sternocleidomastoid muscle may be markedly developed in athletes who perform certain poses or exercises. Also, when these muscles become stiff, they can cause stiff neck and shoulders, so appropriate stretches and massages are recommended.
Tissues associated with sternocleidomastoid muscle: features of the skull
The skull is one of the most important bones that make up the human body and plays a role in protecting the brain. This strong skeleton consists of 22 bones, of which the sternocleidomastoid muscle mainly attaches to the mastoid region, which is part of the skull. The mastoid region is located behind the ear, at the bottom of the skull, and this area is directly connected to the sternocleidomastoid muscle. This connection greatly contributes to head movement and neck mobility.
Tissue associated with sternocleidomastoid muscle: location and position of the skull
The skull is broadly divided into the base of the skull and the skull. The mastoid part, which is directly related to the sternocleidomastoid muscle, is part of the temporal bone, and the temporal bone is one of the bones that make up the base of the skull. The mastoid area is located below the skull, right after the ear canal, and when touched, its protrusion can be clearly felt. This unique position of the mastoid area makes it possible to link neck and head movements through the sternocleidomastoid muscle.
Tissues associated with sternocleidomastoid muscle: skull trivia
The appeal of the skull lies in its complexity and functionality, but there are also some interesting facts about the mastoid region, which connects to the sternocleidomastoid muscle. For example, it is known that the mastoid area develops with age. This part, which is hardly noticeable in infants, becomes prominent as they grow, and is an important structure that supports neck and head movements in adults. Also, despite its small size, the mastoid area is known to have many blood vessels that contribute to blood circulation in the head. These characteristics are part of the wonder and appeal of skulls.
The relationship between the skull and sternocleidomastoid muscles is more than just a physical connection between bones and muscles; it harmonizes head and neck movements. I hope that through this article, readers will gain a deeper understanding of the complex mechanisms of the human body and the parts of the body that are constantly active in everyday life.
