What is the Zygomatic Muscle?
The zygomatic muscle is one of the facial muscles responsible for facial expression movements. It is located in the cheek region and is responsible for raising the corners of the mouth, producing a smile. Furthermore, this muscle is also responsible for assisting in chewing and speaking.
Anatomy of the Zygomatic Muscle
The zygomatic muscle is a fan-shaped muscle that extends from the zygomatic bone, also known as the cheek bone, to the lip region. It is made up of two main parts: the zygomaticus major muscle and the zygomaticus minor muscle.
The zygomaticus major muscle is the most superficial and is responsible for raising the corners of the mouth, producing a smile. It originates in the zygomatic bone and inserts into the skin and the orbicularis oris muscle, which is responsible for closing the lips.
The zygomaticus minor muscle, in turn, is deeper and originates on the zygomatic bone and inserts on the upper lip. It helps to elevate the upper lip and expose the upper teeth during a smile.
Innervation of the Zygomatic Muscle
The zygomatic muscle is innervated by the facial nerve, which is responsible for controlling the movements of the facial muscles. Specifically, the zygomatic muscle is innervated by the zygomatic branch of the facial nerve.
Functions of the Zygomatic Muscle
The zygomatic muscle performs several important functions in the face. The main function of this muscle is to elevate the corners of the mouth, producing a smile. Furthermore, it also helps with chewing, as it is involved in jaw movements.
Another function of the zygomatic muscle is to assist with speech. During the articulation of words, this muscle works together with other facial muscles to produce the movements necessary for the correct pronunciation of sounds.
Zygomatic Muscle Injuries and Pathologies
Just like any other muscle in the body, the zygomatic muscle is also subject to injuries and pathologies. A common injury to this muscle is strain, which occurs when muscle fibers are stretched beyond their normal capacity.
In addition, the zygomatic muscle can also be affected by pathologies such as myositis, which is muscle inflammation, and myalgia, which is muscle pain. These conditions can be caused by several factors, such as trauma, infections or autoimmune diseases.
Treatments for Injuries and Pathologies of the Zygomatic Muscle
Treatment for injuries and pathologies of the zygomatic muscle can vary depending on the severity of the problem. In mild cases, rest and applying cold compresses may be enough to relieve pain and promote recovery.
However, in more serious cases, it may be necessary to resort to more specific treatments, such as physiotherapy, use of anti-inflammatory medications or even surgery, depending on the situation.
Exercises to Strengthen the Zygomatic Muscle
Like other muscles in the body, the zygomatic muscle can also be strengthened through specific exercises. These exercises can help improve the appearance of your face, promoting a more beautiful and healthier smile.
A simple exercise to strengthen the zygomatic muscle is to smile broadly and maintain the smile for a few seconds, repeating the movement several times a day. In addition, it is also possible to use objects, such as a pen, to lift the corners of the mouth.
Final considerations
The zygomatic muscle plays a fundamental role in facial expression movements, being responsible for raising the corners of the mouth and producing a smile. In addition, it also helps with chewing and speaking.
Injuries and pathologies can affect the zygomatic muscle, causing pain and limiting its function. Treatment for these problems may vary, and it is necessary to seek medical advice for an accurate diagnosis and an appropriate treatment plan.
Finally, specific exercises can help strengthen the zygomatic muscle, improving the appearance of the face and promoting a more beautiful and healthier smile.
