What are the lobes of the cerebrum?
The cerebrum consists of two cerebral hemispheres the outer layer called the cortex (gray matter) and the inner layer (white matter). There are four lobes in the cortex, the frontal lobe, parietal lobe, temporal lobe, occipital lobe.
What are the four lobes of sulci?
The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus.
What are the 4 lobes of the cerebrum and each of their functions?
The four lobes include the occipital, temporal, frontal, and parietal lobes. Each lobe is responsible for a specific task. The frontal lobe functions in solving problems, controlling body movements, sentence formation, and personality traits. The occipital lobe functions in processing visual images.
What are the main sulci of the cerebrum?
The main sulci are: Central sulcus – groove separating the frontal and parietal lobes. Lateral sulcus – groove separating the frontal and parietal lobes from the temporal lobe. Lunate sulcus – groove located in the occipital cortex.
How many lobes are in the cerebrum?
Each cerebral hemisphere is divided into five lobes, four of which have the same name as the bone over them: the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe.
What are the 4 lobes and where are they located?
The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus .
What lobe is the central sulcus in?
also called the central fissure, the central sulcus is a prominent sulcus that runs down the middle of the lateral surface of the brain, separating the frontal lobe from the parietal lobe.
How many lobes are in the cerebral hemisphere?
Each cerebral hemisphere divides into four separate lobes by a central sulcus, parieto-occipital sulcus, and lateral fissure.
What sulcus lies in the temporal lobe?
lateral sulcus
Temporal lobe. The temporal lobe lies below the lateral sulcus and is angled downwards and forwards to resemble the thumb of a boxing glove. Its posterior boundary (with the occipital lobe) is the pre-occipital notch. The temporal lobe is involved in hearing, speech comprehension and visual recognition.
Where is the Precentral sulcus?
the frontal lobe
The precentral sulcus is one of the major sulci of the frontal lobe, running in front of and parallel to the central sulcus, separated from it by the precentral gyrus.
Is central sulcus a primary sulcus?
The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex….

Where is the Postcentral sulcus?
the parietal lobe
The postcentral sulcus is a sulcus of the parietal lobe that separates the postcentral gyrus from the remainder of the parietal lobe, thus dividing the primary somatosensory cortex from the secondary somatosensory cortex. It runs parallel and posterior to the central sulcus.
What lobe is the precentral gyrus in?
An important functional area of the frontal lobe is the precentral gyrus, which is located rostral to the central sulcus. The precentral gyrus is called the somato-motor cortex because it controls volitional movements of the contralateral side of the body.
How many sulcus are in the temporal lobe?
Sulci and gyri The temporal lobe is divided into five gyri by four sulci which are oriented largely parallel to the Sylvian fissure.
