The brainstem includes the midbrain, the pons, and the medulla oblongata. They connect the cerebellum to the pons (middle cerebellar peduncle) and midbrain (superior cerebellar peduncle). The brainstem lies beneath the cerebrum and consists of the midbrain, pons and medulla. The brainstem consists of the midbrain, the pons, and the medulla oblongata. Infarction of the pons and medulla oblongata in the brain may cause pathological laughter. It is divided into the midbrain, pons, and medulla oblongata. The brainstem consists of the medulla, the pons and the midbrain. A separating groove between the pons and the medulla is the inferior pontine sulcus. The thalamus relays info between pons (cerebellum link), motor cortices, and insula. It includes the medulla, pons, and cerebellum. The tegmentum forms distinguished divisions in the midbrain, pons, and medulla. The pons and medulla are major structures found there. They receive input from the reticular formation of the pons in the brainstem. These are neurons that are located in the pons of the brainstem. The metencephalon gives rise to the cerebellum and pons.
