Pons

2225

The pons is part of the brainstem that links the medulla oblongata and the thalamus.

It is cranial to the medulla oblongata, caudal to the midbrain, and ventral to the cerebellum.

Its white matter contains tracts that conduct signals from the cerebrum down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.

Measures about 2.5 cm in length.

Appears as a broad anterior bulge rostral to the medulla.

Posteriorly, it consists mainly of two pairs of thick stalks called cerebellar peduncles, which connect the cerebellum to the pons and midbrain.

The pons contains nuclei that relay signals from the forebrain to the cerebellum, and nuclei that deal with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.

Contains the pneumotaxic center, a nucleus that regulates the change from inspiration to expiration.

Implicated in sleep paralysis, and also plays a role in generating dreams.

Cranial nerve nuclei are present in the pons: the trigeminal nerve sensory nucleus (V), the motor nucleus for the trigeminal nerve (V), the abducens nucleus (VI), the facial nerve nucleus (VII), and the vestibulocochlear nuclei (vestibular nuclei and cochlear nuclei) (VIII).
