How Do You Spell MUSCULUS DIGASTRICUS?

1. Musculus digastricus, commonly known as the digastric muscle, is a muscle found in the neck region of humans and some animals. It is a paired muscle that consists of two bellies, the anterior belly and the posterior belly, connected by an intermediate tendinous portion known as the digastric tendon.

   The anterior belly originates from the digastric fossa located on the inner side of the mandible's lower border, while the posterior belly arises from a depression on the mastoid process of the temporal bone. The digastric tendon serves as a pulley system, allowing the muscle to function efficiently.

   The main function of the musculus digastricus is to facilitate the movement of the hyoid bone, which is a small U-shaped bone located in the neck region. When the muscle contracts, it raises the hyoid bone, contributing to actions like swallowing, speaking, and stabilizing the tongue during certain movements.

   In addition to its role in hyoid bone movement, the digastric muscle also assists in opening the mouth and depressing the mandible. It works in conjunction with other muscles to perform these actions, particularly during actions such as chewing and speaking.

   Overall, the musculus digastricus plays an essential role in various movements involving the hyoid bone, mandible, and tongue, contributing to the proper functioning of the neck and oral regions.

2. M. Biventer mandibulae, consists of two bellies united by a central tendon which is connected to the body of the hyoid bone; origin by posterior belly from digastric groove beneath mastoid process; insertion by anterior belly into lower border of mandible near symphysis; action, posterior belly helps to fix hyoid bone, anterior belly depresses jaw; nerve supply, posterior belly from facial, anterior belly by mylohyoid from third division of trigeminus.

Common Misspellings for MUSCULUS DIGASTRICUS

The word musculus digastricus has its origins in Latin. The term is composed of two parts: musculus and digastricus.

Musculus means muscle in Latin, derived from the word musculus meaning little mouse. This term was used to describe small, moving parts of the human body that resembled the movement of a mouse.

Digastricus is a combination of two Latin words: di, meaning two, and gastricus, meaning related to the stomach. Together, digastricus means having two bellies.

Therefore, musculus digastricus can be translated to muscle with two bellies.
