The palatoglossus muscle receives motor innervation from the pharyngeal plexus of vagus nerve. [1] It is the only muscle of the tongue not innervated by the hypoglossal nerve (CN XII). [1]

2023年11月3日 · The palatoglossus is a bow-shaped muscle associated both with the tongue and the soft palate. It originates from the palatine aponeurosis of the soft palate and arches laterally downward to insert into the dorsum of the tongue and blends with the intrinsic muscles.

2024年2月27日 · Palatoglossus. The palatoglossus muscle is also associated with the soft palate – and is therefore innervated by the vagus nerve. Attachments: Arises from the palatine aponeurosis and inserts broadly along the tongue. Function: Elevation of the posterior tongue; Innervation: Vagus nerve.

Discover the role of the palatoglossus muscle in tongue elevation and oropharynx constriction. Learn about its origin, insertion, and arterial supply.

The palatoglossus muscle, also known as musculus palatoglossus, is among the four extrinsic muscles of the tongue and the paired muscles of the soft palate. The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars).

2023年1月17日 · The palatoglossus is an extrinsic muscle of the tongue. It is also associated with the soft palate – and is therefore innervated by the vagus nerve. Attachments: Arises from the palatine aponeurosis and inserts broadly along the tongue. Function: Elevation of the posterior tongue; Innervation: Vagus nerve.

2024年8月20日 · The palatoglossus muscle is one of the four extrinsic muscles of the tongue. The paired muscles create ridges of mucous membrane in the lateral pharyngeal wall called the palatoglossal arches (also known as the anterior pillars of the fauces).

2018年9月14日 · The palatoglossus muscle is a significant anatomical structure located in the oral cavity. It is one of the four extrinsic muscles of the tongue and plays a crucial role in the movement and function of the tongue.

The Palatoglossus is a small fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the glossopalatine arch.

The palatoglossus muscle functions to close off the oral cavity from the oropharynx by elevating the posterior tongue and drawing the soft palate inferiorly. It attaches superiorly to the palatine aponeurosis and inferiorly to the side of the tongue.
