Only the midsagittal view shows the midbrain. It is the middle section of the brain, situated between the thalamus/hypothalamus and pons of the hindbrain. The medulla and pons surround the midbrain. The thalamus and hypothalamus are prominent structures located on the medial surface. The cerebellum lies over the pons and occipital lobes. Its function is coordination.
The choroidplexus is made up of a network blood capillaries that are covered by specialized cells called the ependyma. This structure produces CSF. The structures listed in Martini et al. Fig. 14-13a can be seen on this model. If you’d like to identify the structures in the model, you should refer to the Lab Manual, p. 4 (Fig. 14-13a).
The midsagittal view shows the human brain from the top. It provides information about a variety diagnoses, including the anatomy of the brain and the symptoms that accompany it. Identifying the structures in a midsagittal image requires a thorough knowledge of normal anatomic features. It is possible to identify many structures and spaces in a midsagittal model of the brain. It can also be obtained through MR imaging, computed tomography, and ultrasonography.
The brain model shows the frontal and lateral lobes. These structures are the most obvious, but can be difficult to see from a midsagittal perspective. These structures can be used as a starting point for understanding the brain’s architecture. If you’re interested in learning about the lateral sulcus, you can trace its line over the lateral surface of the brain.
The brain also contains the lateral and the occipital ventricles. The septum pellucidum is a thin membrane that separates the anterior from posterior parts of the lateral ventricular ventricles. It is located in the middle of each hemisphere. The lateral ventricles connect to the fourth ventricle, which lies between the cerebellum and pons.
In the middle of the diencephalon is visible a third ventricle. The fourth ventricle is not clearly identified, but it is in free communication with the posterior cranial fossa. The torcula is elevated in relation to the insertion and removal of the nuchal ligament. Finally, the internal capsule extends to the lambdoid suture. This midsagittal view shows the brain model and identifies these structures.
Besides the occipital lobe, the brain also contains several irregular lateral gyri. This lobe is home to the prominent calcarine fissure. This lobe houses the primary and higher-order vision cortex. A few slices of the brain model are missing from the occipital lobe.
