Pons is located in the upper part of the brain stem. So, what is its function? Is it affected by midbrain injuries? Let us find out in this Bodytomy article.
The human brain is one of the most fascinating organs that exists in the universe. It is a complex organ that has so many parts and functions that the exact areas of the brain and their functions are still being studied. The brain is generally divided into three parts, which are forebrain, midbrain, and hindbrain. The forebrain contains the main part of the brain, which is the cerebrum that forms a bulk of the brain. The midbrain consists of the tectum, tegmentum, and the cerebral peduncles. The hindbrain contains the medulla oblongata, pons, and the cerebellum.
Pons is the region that is located superior to the medulla oblongata, inferior to the midbrain, and ventral to the cerebellum. In simple words, in humans, the pons is above the medulla oblongata, below the midbrain, and anterior to the cerebellum. However, what many people do not know is what function does it actually perform. There are many functions that are served by this part of the brain.
- Trigeminal nerve ― This is the fifth cranial nerve which is both sensory and motor in nature. It is responsible for sensation on the face and it also innervates the muscles of the mandible, which are responsible for biting, chewing, and swallowing food.
- Abducens nerve ― This is a motor nerve which is responsible for sideways movement of the eyes.
- Facial nerve ― This is a motor nerve which affects the muscles of facial expression, like muscles that help in smiling, raising eyebrows, and bringing about various expressions on the face, like shock, fear, joy, etc.
- Vestibulocochlear nerve ― This is a sensory nerve which has two parts ― the cochlear portion, which is involved with transmission of sound from the ear to the brain. The other part is the vestibular portion, which transmits information from the inner ear and helps in maintaining balance and coordination.
If you wish to know more about the function of other parts of the brain, going through diagram of the brain and its functions may be of help. In the end, there are still many aspects of this organ that are yet to be understood!
