The pons develops from the embryonic metencephalon (part of the hindbrain, developed from the rhombencephalon), alongside the cerebellum. In this article, we will look at the anatomy of the pons – its location, structure and function, blood supply and clinical relevance. Anatomical Position The pons is a horseshoe-shaped collection of nerve fibres located in the anterior part of the Its anatomical relations are as follows: • Posteriorly – the cerebellum, separated by the fourth ventricle. • Inferiorly – the medulla oblongata. • Superiorly – the midbrain lies immediately above the pons. External Anatomy Anterior Surface The anterior or ventral surface of the pons is marked by a bulging formed by the transverse pontocerebellar fibres. These fibres wrap around the otherwise vertically oriented brainstem. It measures around 2.5 cm in adults. The basilar groove demarcates the midline of the ventral surface and is where the basilar artery is located. The pontomedullary junction is an important anatomical landmark defined by the angle between the lower border of the pons and the superior border of the medulla. Several cranial nerves originate from the ventral surface of the pons: • ...

The brain connects to the spine and is part of the central nervous system (CNS). The various parts of the brain are responsible for personality, movement, breathing, and other crucial processes that keep people alive. An average adult brain weighs The brain is made up of three main parts, which are the cerebrum, cerebellum, and brain stem. Each of these has a unique function and is made up of several parts as well. Keep reading to learn more about the different parts of the brain, the processes they control, and how they all work together. This article also looks at some ways of maintaining a healthy brain.

When people damage different parts of the brain, they A traumatic brain injury or stroke are Doctors will carry out many tests before reaching a diagnosis of brain death. Brain death is a traumatic experience for everyone involved. It can be particularly difficult to come to terms with the diagnosis, especially if a person can see their loved one breathing and showing signs of life. The brain is composed of The brain sends chemical and electrical signals throughout the body to regulate different biological functions and sense environmental changes. The brain communicates with the majority of the body through the spinal cord. To do this, it uses The cerebrum is the front part of the brain and includes the cerebral cortex. This part of the brain is responsi...
