Pontine branches
Pontine branches
Pontine branches (pronunciation: /ˈpɒntaɪn ˈbræntʃɪz/) are a group of arteries that originate from the basilar artery and supply blood to the pons, a part of the brainstem.
Etymology
The term "pontine" is derived from the Latin word "pons", which means bridge, referring to the bridge-like structure of the pons in the brain. The term "branches" refers to the branching nature of these arteries.
Anatomy
The pontine branches are small arteries that branch off from the basilar artery, a major blood vessel at the base of the brain. They penetrate the pons, supplying it with oxygenated blood. The pons is a part of the brainstem that serves as a bridge between different parts of the brain and plays a crucial role in functions such as sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, and posture.
