Where is the pons on MRI?
The pons (Varolii) is the middle portion of the three parts of the brainstem, sitting above the medulla and below the midbrain.
What is the difference between pons and medulla?
The pons is located superiorly, just above the medulla. It contains nerves that are important for hearing, balance, moving the facial muscles, chewing and looking sideways. The medulla is located inferiorly, just above the spinal cord. It contains neural structures that are vital to sustain human life.
What happens if there is a lesion in the pons?
A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of the pons….Symptoms.
| Structure affected | Effect |
|---|---|
| Lateral spinothalamic tract | Contralateral loss of pain and temperature from the trunk and extremities. |
What is the midbrain pons and medulla?
The named parts, from cranial to caudal, comprise the midbrain (mesencephalon), pons (metencephalon), and medulla oblongata (myelencephalon). Functions include regulation of the cardiac, respiratory, and central nervous systems including consciousness and the sleep cycle.
Is the medulla in the midbrain?
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata….
| Brainstem | |

What happens if the medulla is damaged?
It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.
What structures help medulla?
medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
What happens if there is damage to the medulla?
Where is the pons and medulla located?
brainstem
Structure. The pons is in the brainstem situated between the midbrain and the medulla oblongata, and in front of the cerebellum. A separating groove between the pons and the medulla is the inferior pontine sulcus.
