The spelling of the word "sulcus temporalis transversus" can be explained through its IPA phonetic transcription. The word begins with the "s" sound, which is followed by "ʌl" sound. Then, the "k" sound is pronounced, followed by the "uh" sound. This is followed by the "s" sound, "t" sound and "ɛmp" sound. Then, the "ər" sound is pronounced, followed by "eɪ" and "s" sounds. Finally, the word ends with the "m" sound, "p" sound and "əs" sound.
The term "sulcus temporalis transversus" refers to a specific anatomical feature located in the temporal region of the brain. It is a Latin term composed of several elements: "sulcus" meaning groove, "temporalis" referring to the temporal region, and "transversus" indicating a direction perpendicular to the longitudinal axis.
The sulcus temporalis transversus, also known as the transverse temporal sulcus or Heschl's gyrus, is a prominent groove found within the primary auditory cortex, which is responsible for processing sound information in the brain. It is situated in the lateral part of each hemisphere's superior temporal gyrus.
The sulcus temporalis transversus can be identified as a deep horizontal groove that divides the superior temporal gyrus into two distinct parts: the anterior and posterior transverse temporal gyri. These gyri contain an essential structure called the primary auditory cortex or Brodmann area 41, where initial auditory processing takes place.
Its anatomical location is considered crucial in speech and language processing, as it plays a significant role in sound perception and speech discrimination. It serves as a crucial landmark for neuroimaging studies focusing on auditory information processing, language acquisition, and speech disorders. The sulcus temporalis transversus features distinctive anatomical characteristics which help differentiate the human brain from other mammals, highlighting its importance in higher cognitive functions of hearing and speech.
Transverse temporal s., one of a number of transverse fissures on the surface of the temporal lobe of the cerebrum bordering on the lateral (Sylvian) fissure, running from the region of the superior temporal gyrus to the insula; they separate the transverse temporal convolutions from each other.
