What are the four lobes of the cerebral cortex?
There are four main lobes: frontal, temporal, parietal and occipital.
Label the brain in external lateral view?
The external lateral view of the brain shows the frontal, parietal, temporal, and occipital lobes. The lateral sulcus (Sylvian fissure) separates the temporal lobe from the frontal and parietal lobes. The central sulcus separates the frontal and parietal lobes, while the parieto-occipital sulcus separates the parietal and occipital lobes. The cerebellum is also visible in this view.
What are the Five lobes of cerebral hemispheres?
Frontal Parietal Occipital Temporal Cerebellum
What does bilateral lobes mean?
Bilateral lobes refer to structures that are mirrored or present on both sides of a central axis or line in an organism's body. In the context of brain anatomy, bilateral lobes typically refer to structures like the cerebral hemispheres, which are divided into left and right lobes.
Where do lobes lie at the anterior end of the brain?
At the anterior end of the brain, the lobes primarily consist of the frontal lobes, which are located at the front of the cerebral hemispheres. These lobes are responsible for various functions, including decision-making, problem-solving, and motor function. Additionally, the anterior portion of the brain also includes parts of the parietal lobes, which are situated just behind the frontal lobes and are involved in sensory processing.
What do the ventricles in the brain do?
There are four cerebral ventricles: the paired lateral ventricles, and the midline third and fourth ventricles. The two lateral ventricles, located within the cerebrum, are relatively large and C-shaped, roughly wrapping around the dorsal aspects of the basal ganglia. It is in the lateral ventricles of the embryo that the successive generation of neurons gives rise to the 6-layered structure of the neocortex, constructed from the inside out during development. Each lateral ventricle extends into the frontal, occipital and temporal lobes via the frontal (anterior), occipital (posterior), and temporal (inferior) horns, respectively. The "body" and "atrium" are situated between the anterior/anterior horn and posterior horns. The lateral ventricles both communicate via the interventricular foramina with the third ventricle, found centrally within the diencephalon. The third ventricle communicates via the cerebral aqueduct, located within the midbrain, with the fourth ventricle, found within the hindbrain. The three foramina to the subarachnoid space are found here, permitting cerebrospinal fluid produced in the ventricles to surround the brainstem, cerebellum, and cerebral cortex. The fourth ventricle is also continuous with the central canal, allowing CSF to bathe the inside surface of the spinal cord as well.
What are the regions of the cerebral cortex called?
Lobes. The breakdown is frontal lobes, occipital lobes, parietal lobes, and temporal lobes
How many lobes are there in the liver of a rat?
Rats have six lobes in their liver: left lateral, left median, right lateral, right median, quadrate, and caudate lobes.

What are the five lobes in a pigs liver called?
The fetal pig liver has five lobes: right lateral, right central, left central, left lateral, and caudate
How would you describe the extensions of the dura mater?
Dura mater extensions are found in the skull cavity. They are called the falx cerebri and the tentorium cerebelli. The falx cerebri runs vertically between the fissure in the cerebral hemispheres of the brain. The tentorium cerebelli runs between the cerebellum and the occipital lobes.
What are 6 lobes in cats liver?
right and left medial lobes, the right and left lateral lobes, the quadrate lobe, and the caudate lobe
What is the two pairs arising from the internal carotid artery?
The internal carotid artery gives rise to two main pairs of arteries: the ophthalmic artery and the middle cerebral artery. The ophthalmic artery supplies the eye and surrounding structures, while the middle cerebral artery is a major supplier of blood to the lateral aspects of the cerebral hemisphere, including areas responsible for motor and sensory functions. Additionally, the anterior cerebral artery, another branch, supplies the medial parts of the frontal lobes and superior medial parietal lobes. Together, these branches play crucial roles in cerebral circulation.
In which of the cerebral lobes would broca's area be found?
Frontal Lobe
