The spelling of the word "sulcus temporalis medius" can be explained using the International Phonetic Alphabet (IPA) phonetic transcription. "Sulcus" is pronounced /ˈsʌlkəs/, with the stress on the first syllable. "Temporalis" is pronounced /ˌtɛmpəˈrɑːlɪs/, with the stress on the second syllable. "Medius" is pronounced /ˈmiːdiəs/, with the stress on the first syllable. Together, the word is pronounced /ˈsʌlkəs ˌtɛmpəˈrɑːlɪs ˈmiːdiəs/. It refers to the middle temporal sulcus, an important anatomical feature of the human brain.
The term "sulcus temporalis medius" refers to a specific anatomical feature found in the human brain. It represents a groove or shallow fissure located within the temporal lobe, one of the major divisions of the cerebral cortex.
The temporal lobe is situated on the lateral side of each cerebral hemisphere, and it plays a crucial role in auditory processing, memory formation, and language comprehension. Within this lobe, the sulcus temporalis medius is a distinctive feature that runs horizontally across its surface.
This particular sulcus is positioned between two other major sulci – the superior temporal sulcus and the inferior temporal sulcus. It divides the temporal lobe into superior and inferior gyri, or convoluted ridges of brain tissue. The sulcus temporalis medius is also commonly referred to as the middle temporal sulcus.
Its presence is consistent in most individuals, but slight variations in its location and morphology may occur. The sulcus temporalis medius is considered an important landmark for neurosurgeons and neurologists, aiding in the identification and orientation of different structures and functional areas within the temporal lobe.
Overall, the sulcus temporalis medius is a well-defined groove within the temporal lobe that plays a significant role in the organization and understanding of the human brain's anatomy.
Middle temporal s., second temporal s., a sagittal fissure on the lower part of the lateral surface of the temporal lobe of the cerebrum, separating the middle and inferior temporal convolutions.
