What does the transverse temporal gyrus do?
What does the transverse temporal gyrus do?
The transverse temporal gyri (also called Heschl’s gyri or Heschl’s convolutions) are found in the area of primary auditory cortex buried within the lateral sulcus of the human brain, occupying Brodmann area 41. It is the first cortical structure to process incoming auditory information.
What is the superior border of the superior temporal gyrus?
The superior temporal gyrus is bounded by: the lateral sulcus above; the superior temporal sulcus (not always present or visible) below; an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly.
What is under the superior temporal gyrus?
The superior temporal gyrus contains the primary auditory cortex, which is responsible for processing sounds. The superior temporal gyrus also includes the Wernicke’s area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language.
What is the superior temporal gyrus supplied by?
middle cerebral artery
Arterial supply The superior temporal gyrus receives blood from the middle cerebral artery via all four main temporal branches: the temporopolar artery; anterior temporal artery, middle temporal artery and posterior temporal artery 2.
What is a gyrus?
: a convoluted ridge between anatomical grooves especially : convolution sense 2.
How are gyrus describes?
In neuroanatomy, a gyrus (pl. gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg. sulcus). Gyri and sulci create the folded appearance of the brain in humans and other mammals.
Why do brain have gyri?
Brain gyri and sulci serve two very important functions: They increase the surface area of the cerebral cortex and they form brain divisions. Increasing the surface area of the brain allows more neurons to be packed into the cortex so that it can process more information.
What does temporal gyrus mean?
• TEMPORAL GYRUS (noun) The noun TEMPORAL GYRUS has 1 sense: 1. any of the convolutions of the outer surface of the temporal lobe of the cerebrum . Familiarity information: TEMPORAL GYRUS used as a noun is very rare.
What is the superior temporal gyrus?
The superior temporal gyrus is located in the temporal lobe of the human brain. It’s one of three convolutions, or gyri, in this area, and is the uppermost gyrus of the temporal lobe. It is situated above the external ear.
What is superior temporal lobe?
The superior temporal gyrus is one of three (sometimes two) gyri in the temporal lobe of the human brain, which is located laterally to the head, situated somewhat above the external ear.
