Muscle Digastric

The two bellies are the paired lateral pterygoid muscle, which begins on the skull and ends in the mandible. It is located in the front of the neck, just under the skin and trachea. The function of the digastric muscle is to move the lower jaw forward and backward, as well as to raise the tongue and purse the lips.

In addition, it can be used for yawning and swallowing. In addition, the digastric is one of the most important muscles for maintaining body balance.

The digastric muscle is the main myotome that operates on the facial nerve. The area of ​​responsibility of this muscle covers the nose, lips, upper gums, lower jaw, oral cavity, tongue and upper



The digastric muscle is one of the muscles of the neck, which is located under the cheek, above the larynx and is formed by two fibrous layers. It is one of the most important muscles, which is responsible for maintaining the head and neck in the correct position, and also ensures various movements of the lower jaw.

Description of the muscle: The muscle has the shape of a trapezoid and consists of two bellies - the anterior (narrower and sharper) and the posterior (wider and blunter). The anterior belly begins from the greater tubercle on the occipital bone and passes forward through the lower part of the zygomatic arch, dividing into two tendons that connect to the external occipital protuberance of the skull. The posterior belly extends downward and backward, passing under the subcutaneous muscle of the neck, where it joins the suture of the body of the hyoid bone.

Function of the muscle: The task of the digastric muscle is to lift the lower jaw up and forward. It also plays a role in tongue movement and swallowing by supporting and positioning the soft palate. Together with the other condyles, it is involved in the masticatory movements of the lower jaw, including opening and closing the mouth, chewing and speaking.

Impact of muscle disorders: Digastric muscle disorders can be associated with various diseases or injuries. One example is a retropharyngeal abscess, where inflammation extends to the deep throat, affecting the digastric muscle. This can block the mouth from opening and cause pain and discomfort when swallowing. In addition, strong or frequently repeated movements of this muscle can lead to traumatic damage to its structure. These disorders can lead not only to severe pain, but also to deterioration of hearing and speech.
