Infraglottic (/ˌɪnfrəˈɡlɒtɪk/) is a medical term that refers to the region below the vocal cords. The word is derived from the Latin roots infra- (meaning below) and glottis (meaning vocal cords). The IPA phonetic transcription is helpful in understanding the spelling of this complex medical term. The stress is on the second syllable and the ‘a’ in ‘gly’ is pronounced as ‘o’. Correct spelling is important in medical communication to avoid any confusion in diagnosis and treatment.
The term "infraglottic" refers to a specific anatomical region located below or within the glottis. The glottis is an essential part of the human larynx, responsible for producing sound during phonation. It consists of the vocal cords and the space between them.
The prefix "infra-" indicates that "infraglottic" pertains to structures situated below the glottis. This anatomical region encompasses various components, including the subglottis and the infraglottic cavity. The subglottis refers to the area beneath the glottis down to the lower edge of the cricoid cartilage. It contains the lower region of the larynx and is essential for vocalization and air passage.
The infraglottic cavity, on the other hand, refers to the space below the subglottis. It extends further down into the trachea and forms part of the lower respiratory system. It plays a crucial role in the transmission of air, as well as in preventing the aspiration of foreign bodies into the lungs.
The term "infraglottic" is commonly used in medical and anatomical contexts, particularly in relation to the larynx and respiratory system. Understanding this term aids in describing and studying the structures and functions of the lower portion of the larynx, including the subglottis and infraglottic cavity.
Below the glottis, subglottic.

The word infraglottic is derived from two components: infra- and glottic.
1. Infra- is a prefix in Latin, meaning below or under. It is commonly used when referring to something situated beneath, beneath a particular limit or position.
2. Glottic relates to the glottis, which is the part of our vocal apparatus located in the larynx, specifically the space between the vocal cords.
Combining these two components, infraglottic essentially means below the glottis or pertaining to the area below the vocal cords.
