PHARYNGEAL MUSCLE Meaning and
Definition
-
Pharyngeal muscles are a group of muscles located in the throat or pharynx. The pharynx is a muscular tube that connects the nasal cavity and the mouth to the esophagus and larynx. These muscles have essential functions in swallowing, speaking, and breathing.
The pharynx is divided into three regions: the nasopharynx, located behind the nasal cavity; the oropharynx, situated behind the mouth; and the laryngopharynx, situated beneath the epiglottis and above the esophagus. Pharyngeal muscles are responsible for the movement and coordination of these regions during swallowing and speech.
There are several key pharyngeal muscles, including the superior, middle, and inferior pharyngeal constrictor muscles. As their name suggests, these muscles have a constricting action that helps propel food and liquid down the throat and into the esophagus during swallowing. Other important pharyngeal muscles include the stylopharyngeus and palatopharyngeus muscles, which are involved in elevating the larynx during swallowing.
The pharyngeal muscles are controlled by the cranial nerves, particularly the glossopharyngeal nerve (CN IX), vagus nerve (CN X), and the accessory nerve (CN XI). These nerves play a crucial role in coordinating the movement of these muscles during swallowing and speech production.
In summary, pharyngeal muscles are a group of muscles located in the throat that are responsible for swallowing, speaking, and breathing. They play a vital role in the movement and coordination of different regions of the pharynx during these processes.

Etymology of PHARYNGEAL MUSCLE
The term "pharyngeal muscle" is derived from the combination of two words: "pharyngeal" and "muscle".
1. Pharyngeal: The word "pharyngeal" comes from the Greek word "pharúnx", which means "throat" or "the back part of the mouth". It is derived from the Indo-European root "bhā-", meaning "to speak" or "to sound". In Latin, it became "pharynx", and eventually entered the English language as "pharynx", referring to the passageway in the throat that connects the nasal and oral cavities to the esophagus and larynx.
2. Muscle: The word "muscle" is derived from the Latin term "musculus", which means "little mouse". This name was given due to the observation that contracting muscles resemble small mice moving under the skin.
