Introduction:

The brain is the prime organ of the CNS (central nervous system). It is divided into six major regions on the basis of structure and function, which are cerebrum, cerebellum, medulla oblongata, pons, diencephalon, and mesencephalon.

Explanation of Solution

The structures of the midsagittal section of the brain are labeled as below:

EBK HUMAN ANATOMY, Chapter 16, Problem 1RFT , additional homework tip  2

Thalamus: It is a part of the diencephalon that is further divided into right and left thalamus. This region is assigned the duty to relay and process sensory information across the brain.

Corpus callosum: It is a bundle of commissural fibers that connects the two cerebral hemispheres. It functions to transfer information from one hemisphere to another. It contains the largest portion of the white matter in the brain.

Cerebral aqueduct: It is a part of the mesencephalon or midbrain. It connects the third and fourth ventricles within the diencephalon and mesencephalon respectively. It is filled with cerebrospinal fluid (CSF), which flows into the ventricles.

Cerebellum: It is a part of the hindbrain and called as the small brain. It functions to relay motor sensations and is involved in intellectual development. It also maintains the posture of the body.

Pons: It is a part of the brainstem and is located below the midbrain, above the medulla oblongata and anterior to the cerebellum. It functions to relay sensory information between the thalamus and the cerebellum. It is responsible for the maintenance of body posture, hearing, taste, touch, pain, facial expression, chewing, salivation, and secretion of tears.

Conclusion

Therefore, the structures of a midsagittal section of the brain are:

a Thalamus
b Corpus callosum
c Cerebral aqueduct
d Cerebellum
e Pons
