A digastric muscle is a small muscle located under the jaw. It plays a crucial role in opening the mouth and swallowing. Comprised of two muscle bellies connected by an intermediate tendon, the digastric muscle is essential for various functions related to the movement of the lower jaw.
Structure of Digastric Muscle
The digastric muscle consists of an anterior belly and a posterior belly, each serving different functions. The anterior belly originates from the digastric fossa of the mandible, while the posterior belly arises from the mastoid notch of the temporal bone. These two bellies are connected by an intermediate tendon that passes through a fibrous sling in the hyoid bone.
Function of the Digastric Muscle
The digastric muscle is responsible for opening the jaw by depressing the mandible. It also aids in swallowing by controlling the movement of the hyoid bone during the swallowing process. The muscle works in coordination with other muscles of the neck and throat to facilitate these essential functions.
Common Disorders of the Digastric Muscle
One common disorder related to the digastric muscle is myofascial pain syndrome, which can cause discomfort, tenderness, and limited movement in the jaw. Another condition is the hypertrophy of the digastric muscle, characterized by an enlargement of the muscle due to various factors such as excessive strain or other underlying health issues.
Overall, the digastric muscle is a critical component of the musculature involved in basic functions like chewing, speaking, and swallowing. Understanding its structure and function is key to comprehending the intricate mechanisms of the human body.
