Pontine branches

Pontine branches are a group of arteries that supply blood to the pons, a part of the brainstem. They originate from the basilar artery, which is a major blood vessel of the brain.

Anatomy

The pontine branches are small arteries that branch off from the basilar artery. They penetrate the pons at right angles, supplying it with oxygenated blood. The number of pontine branches can vary, but there are typically several on each side of the basilar artery.

Function

The primary function of the pontine branches is to supply blood to the pons. The pons is a crucial part of the brainstem, involved in several key functions such as the regulation of breathing, sleep, and sensory processing. By supplying the pons with blood, the pontine branches play a vital role in maintaining these functions.

Clinical significance

Damage or blockage of the pontine branches can lead to serious medical conditions. For example, a stroke can occur if blood flow through the pontine branches is interrupted. This can result in damage to the pons and associated loss of function.
