In this article, I will explain the “deltoid muscle” in detail. In addition to the role, structure, and importance of muscles, we will also touch on proper training methods and points to keep in mind in daily life. In addition, it also provides information on stretches, exercises, and other ways to care for your deltoid muscles to keep them healthy. Please use this article to deepen your understanding of the body.

What is the deltoid muscle
The deltoid muscle is one of the three shoulder muscles located in the upper arm of the human body. It forms the shoulder and plays an important role in arm movement. In particular, it is essential for movements such as raising an arm or stretching it sideways. Since the shape of the muscle is triangular, it was named “deltoid muscle.”
How to read deltoid muscle
The pronunciation of deltoid muscle is “triangular muscle.” The name comes from the ease of reading in Japanese and its shape, and it is a name often used in the fields of muscle training and medicine.
Characteristics of deltoid muscles
The deltoid muscle is divided into three parts: anterior (anterior deltoid muscle), middle (middle deltoid muscle), and posterior (posterior deltoid muscle). Each of these supports different movements and plays a role in increasing shoulder stability and range of motion. As the name suggests, the shape of a muscle is triangular.
Location and position of deltoid muscles
The location of the deltoid muscle can be clearly seen by looking at the human anatomy chart. It starts above the shoulder blades and collarbone and is attached to the humerus. This muscle forms the outline of the shoulder and has an important role in supporting arm movement.
How to memorize deltoid muscles
One way to remember the position and function of the deltoid muscle is to actually touch it. As you move your shoulders, you can feel the middle part in particular moving. Also, it is effective to exercise while being aware of the deltoid muscle and feel that movement with your body.
English and Latin for deltoid muscle
Deltoid muscle is expressed in English as “Deltoid Muscle.” It comes from the Greek letter delta (delta), or triangle. It is expressed as “Musculus Deltoideus” in Latin.
Trivia about deltoid muscles
The deltoid muscle is one of the most easily developed parts of the muscle. By being trained well, the silhouette of the shoulders will be clear and the appearance will be strong. In addition, the deltoid muscle also plays an important role in preventing shoulder dislocations and injuries.
Tissues associated with the deltoid muscle: characteristics of the humerus
The humerus bone is a bone in the human body located in the upper arm from the shoulder to the elbow, and is regarded as one of the main bones of the upper limb. This bone acts like a pillar that supports the whole body, and controls movement in connection with various muscles. In particular, the shoulder muscle called the deltoid muscle has a close relationship with the humerus bone. The deltoid muscle is a muscle that directly affects shoulder movement, and it attaches to the humerus bone and allows the arm to be raised, lowered, and rotated. Therefore, the strength of the deltoid muscle has a big impact on arm strength and range of motion.
Tissues related to deltoid muscle: location and position of the humerus
To understand the relationship between the humerus bone and the deltoid muscle, it is important to know exactly where it is. The humerus bone is located between the shoulder joint and elbow joint, and is the longest bone in the upper limb in terms of length. Meanwhile, the deltoid muscle is a large muscle located in the shoulder and is divided into three parts: front, middle, and back. This muscle is attached to the outside of the humerus bone, and each part of the deltoid muscle exerts strength in different directions to support arm movements from multiple angles.
Tissues associated with deltoid muscle: trivia about the humerus
There are various interesting facts about the humerus and deltoid muscles. For example, the central part of the humerus bone has a rough surface (bone), which is the attachment point for muscles, and many muscles are attached to this part, but of these, the middle part of the deltoid muscle has the most pronounced effect. Also, the deltoid muscle takes the lead in the movement of swinging up the arm powerfully, and this movement is made up of cooperation between the humerus bone and the deltoid muscle.
Additionally, proper exercise and nutrition are essential for maintaining the health of the deltoid muscles and humerus. Strength exercises such as push-ups and dumbbell lifts have the effect of strengthening these tissues. Also, eating foods rich in calcium and vitamin D can support bone health.
Thus, the humerus and deltoid muscles play an essential role in our daily lives and sports performance. By understanding the valuable relationships between these structures and providing proper care, you can maintain a healthy body and maximize performance.
Deltoid muscle quiz and correct answers
Q: What are the three parts of the deltoid muscle called in English?
1. deltoid anterior muscle
2. deltoid middle muscle
3. posterior deltoid muscle
A: 1. Annoying Deltoid, 2. Lateral Deltoid, 3. Posterior Deltoid
With that, I was able to deepen my understanding of the deltoid muscle through details about the deltoid muscle, its location and function, names in English and Latin, and a little trivia and simple quizzes. Let's find out how to effectively train this important muscle for weight training, sports, and aiming for a beautiful body line.
summary
This time, I explained the location and position of the “deltoid muscle”, how to memorize it, and the English/Latin notation.
