Located just below the mylohyoid muscle in your neck lies a small but crucial gland known as the thyroid gland. Although it might be small, the thyroid gland has a significant impact on your overall health and well-being. A vital part of your endocrine system, the thyroid gland is responsible for producing hormones that regulate metabolism, growth, and development.
Despite its importance, you may not give much thought to the thyroid gland until something goes wrong. And unfortunately, problems with the thyroid gland are all too common. In fact, an estimated 20 million Americans have some form of thyroid disease, ranging from an underactive thyroid to an overactive thyroid. These conditions can create a wide range of symptoms, from fatigue and weight gain to hair loss and anxiety. If you’re experiencing any of these symptoms, it’s worth considering whether your thyroid gland might be the culprit.
Anatomy of the Inferior Oral Cavity
The inferior oral cavity refers to the lower part of the mouth that is positioned below the tongue. It contains various structures that play essential roles in oral and digestive functions. One of the prominent structures found in the inferior oral cavity is the mylohyoid muscle.
- The Mylohyoid Muscle: The mylohyoid muscle is a thin, flat muscle that forms the floor of the mouth. It is located inferior to the tongue and is responsible for elevating the hyoid bone during swallowing. The muscle originates from the mylohyoid line of the mandible and inserts into the hyoid bone. The mylohyoid muscle divides the inferior oral cavity into two regions – the sublingual space and the submandibular space.
- The Sublingual Space: The sublingual space is a triangular space located inferior to the tongue and superior to the mylohyoid muscle. It contains the sublingual gland, which secretes saliva, and several small ducts that drain saliva into the oral cavity. The sublingual space is also the site of the lingual nerve, which supplies sensation to the tongue and the floor of the mouth.
- The Submandibular Space: The submandibular space is a larger space located inferior to the mylohyoid muscle and superior to the anterior border of the cervical fascia. It contains the submandibular gland, which produces most of the saliva in the oral cavity. The submandibular space also contains several other structures, including the hypoglossal nerve, the lingual artery, the deep portion of the submandibular lymph nodes, and the submandibular duct.
Overall, the anatomy of the inferior oral cavity is complex and comprises many interconnected structures that work together to facilitate oral and digestive functions. Understanding the anatomy of this area is crucial for dental and medical professionals to diagnose and treat various conditions that affect the oral cavity.
Functions of the Mylohyoid Muscle
The mylohyoid muscle is one of the paired muscles that runs along the floor of the mouth and is located inferior to the tongue. These muscles are involved in various functions that contribute to oral and swallowing abilities.
- Lifts the floor of the mouth: When the mylohyoid muscle contracts, it elevates the floor of the mouth, which helps in deglutition (swallowing) process. It plays a significant role in initiating the swallowing action.
- Stabilizes the hyoid bone: The mylohyoid muscle keeps the hyoid bone stable during swallowing, which is critical in preventing aspiration- when food or liquid enters the lungs instead of the esophagus. The hyoid bone serves as an anchor for various muscles, including the tongue, mandible, and larynx, which work together to produce coordinated movements during swallowing.
- Aids in speech: The mylohyoid muscle also contributes to speech by influencing the movement and position of the tongue and mandible. It helps in producing sounds such as /t/ and /d/ by positioning the tongue against the hard palate.
The mylohyoid muscle is interconnected with other muscles and structures in the head and neck, and any impairment of its function can lead to various complications, which can affect swallowing, breathing, and speech abilities.
The table below shows the nerve and blood supply that gives rise to the mylohyoid muscle.
| Nerve | Artery |
|---|---|
| Mylohyoid nerve (branch of mandibular nerve) | Inferior alveolar artery (branch of the maxillary artery) |
Overall, the mylohyoid muscle is a vital structure in the oral and swallowing functions, and understanding its role can help diagnose and manage various disorders related to the head and neck region.
Common Pathologies Affecting the Mylohyoid Muscle
