The geniohyoid is a paired short muscle that arises from the inferior mental spine, on the back of the mandibular symphysis, and runs backward and slightly downward, to be inserted into the anterior surface of the body of the hyoid bone.

2023年10月30日 · Geniohyoid muscle is a short, paired muscle that belongs to the suprahyoid muscle group of the neck. Together with the digastric, stylohyoid and mylohyoid muscles, it constitutes the floor of the oral cavity. Its main function is to coordinate the movements of the floor of the mouth and the hyoid bone while swallowing and voice production.

2024年8月20日 · The geniohyoid muscle is one of the suprahyoid muscles of the neck that is innervated by the ventral ramus of C1. Geniohyoid draws the hyoid bone up and forward during mastication and assists the opening of the mandible.

2023年1月20日 · The geniohyoid is a suprahyoid muscle of the neck. It is located either side of the midline of the neck, deep to the mylohyoid muscle. Attachments: Arises from the inferior mental spine of the mandible. It then travels inferiorly and posteriorly to attach to the hyoid bone. Actions: Depresses the mandible and elevates the hyoid bone.

Discover the Geniohyoid muscle's origin, action, innervation, and arterial supply for a comprehensive understanding.

2024年10月30日 · The geniohyoid muscle originates from the inferior mental spine (inferior genial tubercle) and inserts on the body of the hyoid bone. The geniohyoid muscle receives its primary innervation from the first cervical nerve (C1) via the hypoglossal nerve (cranial nerve XII).

2023年6月5日 · Geniohyoid Muscle: It is short, slender, ribbon-shaped muscle, situated deep to mylohyoid, representing the most proximal component of rectus cervices muscle. It takes origin from the inferior genial tubercle (symphysis menti) and gets inserted to …

2025年1月17日 · The geniohyoid muscle is a flat, triangular muscle that arises from the inner surface of the mandible (lower jaw bone) just below the symphysis (midline joint). It extends upwards and backwards to insert into the hyoid bone.

Action: Depresses of the mandible at the temporomandibular joints (TMJs), flexes the neck at the spinal joints, elevates the hyoid bone. The Geniohyoideus (Geniohyoid muscle) is a narrow muscle, situated above the medial border of the Mylohyoideus.

The geniohyoid is a narrow paired muscle and is one of the four suprahyoid muscles: the digastric, the mylohyoid, the stylohyoid, and the geniohyoid. The muscle lies above the mylohyoid on the medial side in contact with its opposite partner. Occasionally it is not separated as a paired muscle but is contiguous as a single muscle.
