What is spiral cord?
A column of nerve tissue
that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones).
What is the insula?
The insula (or insular cortex) is
a thin ribbon of gray matter tissue
that lies just deep to the lateral brain surface, separating the temporal lobe from the inferior parietal cortex.
Where is Wernicke’s area?
Wernicke area, region of the brain that contains motor neurons involved in the comprehension of speech. This area was first described in 1874 by German neurologist Carl Wernicke. The Wernicke area is located in
the posterior third of the upper temporal convolution of the left hemisphere of the brain
.
Where are the frontal and temporal lobes located?
The temporal lobe sits
at the bottom middle portion of the brain
, just behind the temples within the skull, which is also where it gets its name. It also sits above the brain stem and cerebellum. The frontal and parietal lobes are above the temporal lobe. The occipital lobe sits just behind it.
What is the Broca area?
Broca area, also called convolution of Broca,
region of the brain that contains neurons involved in speech function
. … The Broca area lies specifically in the third frontal convolution, just anterior to the face area of the motor cortex and just above the Sylvian fissure.
What is Broca’s area in the brain?
Broca’s area is also known as
the motor speech area
