The classification of the strongest muscle in the human body may vary depending on its location and function. For example, if the strongest muscle is chosen on the basis of endurance, it will be the heart muscle. If the selection is based on the strength of contraction and relaxation, then it will be the uterine muscle. In the following article, we will talk about what is the strongest muscle in the human body? And what else is the biggest muscle?

The strongest muscle in the human body

Determining the strongest muscle in the human body is debatable. Some physiologists believe that the strongest muscle is the jaw; This is due to its ability to chew. While others believe that the buttock or thigh muscle is the strongest; So it is not easy to determine.

The difficulty in determining what is the strongest muscle in the body is due to the fact that the muscles do not work on their own. For example, the thigh muscle cannot be compared directly with other muscles. Because it consists of several muscles that contract together, not just one muscle.

In addition to the presence of other biomechanical factors that must be taken into account when determining the strongest muscle in the human body, such as the length of the muscles, and the points of contact of the muscles with each other.

Below we will talk about Muscles considered the strongest based on different definitions of strength:

buttock muscle

It is called in English (Gluteus Maximus), and the gluteus maximus muscle (buttock muscle) is the largest muscle in the human body, and it is linked to the coccyx muscle that is located at the end of the spine.

It is also one of the strongest muscles in the body. Because it performs the task of maintaining the torso of the body in an erect position, which helps the process of standing and sitting, as well as in climbing stairs.

External eye muscles

It is called in English (External Muscles of the Eye), and these muscles are constantly moving to reset eye positions. When the head is in motion, the extrinsic muscles constantly adjust the position of the eye to maintain a fixed fixation point.

With the continuous movement, the external eye muscles are subject to fatigue. In an hour of reading a book, the eyes make approximately 10,000 movements.

heart muscle

It is called in English (Heart Muscle), and some scholars consider it to be the strongest muscle in the human body. For its ability to endure and work continuously, the heart pumps about 71 grams of blood with each beat, and the heart has the ability to beat more than 3 billion times in a person’s life.

Jaw muscles

It is called the Masseter, and some consider it the strongest muscle in the human body depending on its weight. When all the jaw muscles work together, it can close teeth with a force of up to 55 pounds (25 kg) on ​​the incisors or 200 pounds (90.7 kg) on ​​the molars.

The muscles of the uterus

It is called in English (Muscles of the Uterus), and the uterus is located in the lower pelvic region, and some describe it as the strongest muscle of the body; Because of its ability to contract and relax during pregnancy and childbirth, the oxytocin hormone secreted by the pituitary gland helps stimulate these contractions.

soleus muscle

It is called in English (Soleus), and it is the muscle that is located below the calf muscle, and some consider that the soleus muscle is the strongest muscle in the human body; For its very great importance in walking, running and dancing. It is considered a very strong muscle along with the leg muscles; Because it pulls the force of gravity to keep the body upright.

tongue muscle

It is called in English (Tongue Muscle), and this muscle does a hard job, as it works permanently and continuously like the heart muscle.

The tongue consists of groups of muscles, which help it in the process of mixing food, in addition to its role in the process of pronunciation and the ability to speak, and its contribution to the process of tasting as well.

What is the strongest muscle in a man’s body?

The jaw muscles (especially the masseter muscle) are among the strongest muscles in the body; This is due to its ability to generate great force during chewing. This muscle is stronger in men than in women, so some may consider it the strongest muscle in a man’s body.

What is the strongest involuntary muscle in the body?

The heart pumps daily at least 9450 liters of blood, and it has the ability to beat more than 3 billion times in a person’s life; So some scientists consider it the strongest involuntary muscle in the body.
