Utricle (== Template:IPA
The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.

- Phonetic notation: A system used to visually represent the sounds of speech. The IPA is one type of phonetic notation.
- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form. In linguistics, this is often done using the IPA.

The Utricle is a part of the vestibular system in the inner ear that plays a key role in maintaining balance and spatial orientation.
Etymology
The term "Utricle" is derived from the Latin word "utriculus", which means "small bag" or "pouch". This is a fitting description as the utricle is a small, sac-like structure.
Function
The utricle, along with the saccule, is one of the two otolith organs located in the vestibule of the inner ear. These organs are responsible for detecting linear accelerations and head tilts in relation to gravity. The utricle specifically responds to changes in horizontal movement and head position.
Structure
The utricle is a small, oval-shaped structure filled with a fluid called endolymph. It contains a sensory epithelium area known as the macula of utricle, which is covered with hair cells. These hair cells are sensory receptors that detect motion and changes in position.
