The Muscular Triangle (pronounced: muhs-kyuh-luhr trai-an-guhl) is a region of the neck that is significant in the field of Anatomy.
Etymology
The term "Muscular Triangle" is derived from the Latin words "musculus" meaning muscle, and "triangulum" meaning triangle.
Definition
The Muscular Triangle is a region of the neck bounded by the Sternocleidomastoid muscle, the Superior belly of the omohyoid muscle, and the anterior midline of the neck. It is one of the four triangles of the neck, the others being the Submental Triangle, the Submandibular Triangle, and the Carotid Triangle.
Anatomical Details
The floor of the Muscular Triangle is formed by three muscles: the Thyrohyoid muscle, the Sternothyroid muscle, and the Sternohyoid muscle. The roof is formed by the platysma and the skin. The contents of the Muscular Triangle include the Thyroid gland, the Parathyroid glands, and parts of the Larynx and Pharynx.
Clinical Significance
The Muscular Triangle is of clinical importance as it contains vital structures such as the thyroid and parathyroid glands. Disorders of these glands, such as Hyperthyroidism, Hypothyroidism, and Parathyroid disorders, can have significant health implications.
