In this article, I will explain “triceps brachialis” in detail.
The triceps muscle is a muscle located on the back of the arm and plays an important role in stretching the arm. We will introduce the structure, function, and training methods of this muscle in a wide range of ways, from basics to applications, and touch on how to strengthen it in real life and prevent injuries. Understanding muscle mechanisms and training methods is essential for building strength more efficiently. Please use this article to deepen your understanding of the body.

What are triceps brachialis
The triceps is a muscle located on the back of our arm and is mainly responsible for extending the arm. It is a muscle frequently used in everyday life, such as stretching arms strongly and lifting objects.
How to read triceps
It is read as “Jowan San Tokin.” As the name suggests, it comes from the fact that this muscle consists of three parts in the upper arm.
Characteristics of triceps
As the name suggests, triceps has three heads, and while each has a different starting part, they are connected to a common stop. This structure provides strength and stability when extending the arm.
Location and position of triceps brachialis

The triceps brachius muscle is located at the back of the upper arm and extends between the shoulder blade and elbow. A “human anatomy chart” is very useful in order to correctly understand its location.
How to memorize triceps
As you can see from its name, this muscle has “three heads.” Therefore, it's a good idea to remember them as “three powerful stretches.”
English and Latin for triceps
“Triceps Brachii” in English, and “Triceps Brachii” in Latin. Both words are literally translated as “three heads of arms.”
Triceps trivia
This muscle not only stretches the arm, but also greatly contributes to stabilizing the elbow joint. It is also one of the largest muscles among the upper arm muscles.
Tissues associated with triceps brachialis: characteristics of the shoulder joint
The shoulder joint is one of the joints with the widest range of motion in the human body. The flexibility and breadth of movement in this joint is provided by many tissues, such as shoulder blades, humerus, collarbone, and muscles, tendons, ligaments, and cartilage. The long head of the triceps muscle attaches to the lower end of the scapula joint and contributes slightly to shoulder joint movement, but it is mainly responsible for elbow joint extension.
Tissues related to triceps brachialis muscle: location and position of shoulder joint
The shoulder joint functions as the main joint connecting the upper limbs of the human body to the torso. Specifically, the head of the humerus bone and the joint socket of the scapula form a joint. The triceps brachial muscle is located at the back of the upper arm and mainly stretches the elbow joint, but it also contributes slightly to shoulder joint stability. This combination of joints and muscles allows us to move our arms freely.
Tissues associated with triceps brachiae: shoulder joint trivia
Interestingly, the large range of motion of the shoulder joint is also sometimes a factor that increases the risk of dislocation or injury. This risk is further increased when surrounding muscles, such as triceps, are not properly strengthened. Therefore, regular training of the muscles around the shoulder (rotator cuff, deltoid muscle, etc.), including triceps, is very important in maintaining the health and function of the shoulder joint.
Triceps quiz with correct answers
Q1What part of the arm is the triceps brachial muscle located in?
Correct answer: posterior part of upper arm
Q2. What is the main function of the triceps muscle?
Correct answer: arm extension
summary
This time, I explained the location and position of “triceps brachii”, how to memorize it, and the English/Latin notation.
How was it?
I would be happy if reading this article deepened my understanding of anatomy.
Learning is a long, never-ending journey, but I sincerely wish you all the best. Let's continue to study together and work hard for the national exam!
Please look forward to the next blog.
