SPINA TYMPANICA MINOR Meaning and
Definition
-
Spina tympanica minor, also known as the spine of the tympanic bone, is a small bony protrusion found in the human anatomy. It is specifically located on the inner wall of the middle ear, within the temporal bone, which is part of the skull.
This anatomical structure is a thin, sharp projection that protrudes from the inferior portion of the tympanic cavity, near the junction with the jugular fossa. Although it varies in size among individuals, the spina tympanica minor is generally described as a small and delicate feature.
The main function of the spina tympanica minor is uncertain and its significance is yet to be fully elucidated. However, it is believed to participate in the suspension mechanism of the tympanic membrane (eardrum). It may serve as a point of attachment for certain ligaments and muscles of the middle ear, aiding in the regulation of sound transmission and overall function of the auditory system.
It is important to note that the spina tympanica minor is a small and intricate anatomical feature, typically only visible under microscopic examination or during surgical procedures.
