Anatomy Of The Pons

It is an especially important structure of the human nervous system as it is a portion of the brainstem an area through which all information that travels throughout the nervous system must pass at some point. The cerebellum overlies the pons It is connected by three pairs of cerebellar peduncles.

The pons is a portion of the hindbrain that connects the cerebral cortex with the medulla oblongata.

Anatomy of the pons. The pons is a structure of the vertebrate nervous system that can be found in the hindbrain the lowest region of the brain. Transversely running fibers pontocerebellar can be seen on this surface. The ventral aspect of pons shows the following features.

The transverse section of pons is studied at two levels. The ventral part contains longitudinal fibers primarily from the corticospinal corticobulbar and corticopontine tracts. The pons is a broad horseshoe-shaped mass of transverse nerve fibres that connect the medulla with the cerebellum.

Fibres from the pontine nuclei cross the midline and form the middle cerebellar peduncles on their way to the cerebellum. The fourth ventricle is found between the dorsal surface of the pons and the cerebellum. MRI of the brain T1-weighted sagittal view.

Ventral surface is convex and has a shallow groove in the midline called basilar groove which lodges basilar artery. It also serves as a communications and coordination center between the two hemispheres of the brain. The pons has a bulbous shape and has two main components - the basis pontis basalventral part and the pontine tegmentum dorsal part.

The basilar pons contains a complex combination of tracts bundles of axons and nuclei collections of cell bodies of neurons. The pons is divisible into - ventral part basilar dorsal part Tegmentum. The cavity of pons is formed by the fourth ventricle present in the posterior part.

Anterior and lateral corticospinal corticobulbar and corticopontine tracts with transverse fibers contributing to the bulk of the pons. The internal anatomical features of pons can be viewed by studying the transverse section of pons. The dorsal tegmentum contains the nuclei of the trigeminal V.

This photo gallery presents the anatomy of Pons by means of MRI T1-weighted sagittal axial and coronal views. It appears as a pear-shaped structure with pontine fibers running transversely in the anterior part. The pons measures roughly 25 centimeters 098 in in length.

The pons itself is divided into a back medically called dorsal part and a front medically called ventral part. Each piece plays a different role relaying messages from the brain to the rest of the body. - contains transverse and vertical fibres Pontine nuclei.

Midbrain Mesencephalon The midbrain or mesencephalon is the most rostral part of the brainstem that connects the pons and cerebellum with the forebrain For most of its part the midbrain sits in the posterior cranial fossa traversing the hiatus of the tentorium cerebelli. Pons portion of the brainstem lying above the medulla oblongata and below the cerebellum and the cavity of the fourth ventricle. The basis pontis consists of white matter tracts eg.

The pons Latin for bridge is part of the brainstem and in humans and other bipeds lies inferior to the midbrain superior to the medulla oblongata and anterior to the cerebellum. The pons is a broad horseshoe-like shaped mass of transverse nerve fibers that connect between the cerebrum and cerebellum. The pons connects the brain to the cerebellum and can be divided into a ventral part and a dorsal tegmentum Figs 10 11 8.

There are 4 paired cranial nerves one on the left and one on the right that start in the pons. The pons is a portion of the hindbrain that connects the cerebral cortex with the medulla oblongata. The pons connects the brain to the cerebellum and can be divided into a ventral part and a dorsal tegmentum.

The pons is also called the pons Varolii bridge of Varolius after the Italian anatomist and surgeon Costanzo Varolio 154375. These fibers connect cerebrum to cerebellum via middle cerebellar peduncle. The ventral part contains longitudinal fibers primarily from the corticospinal corticobulbar and corticopontine tracts.

The ventral surface of the pons is dominated by fibers which form a large ventral enlargement that carries fibers from pontine nuclei to the cerebellum in the middle cerebellar peduncle. The ventral pons contains the pontine nuclei which are responsible for coordinating movement. It is also the point of origin or termination for four of the cranial nerves that transfer sensory.

The back part is often called the Pontine Tegmentum whereas the front part is called the Ventral or Basal Pons. The pons is comprised of two major components the ventral pons and the tegmentum. The pons is located in the brainstem which is the area where the brain connects to the spinal cord.

Pons a portion of the brain lying inferior to the midbrain above the medulla oblongata and anterior to the cerebellum. Although it is small at approximately 25 centimeters long it serves several important. As a part of the brainstem the pons helps in the transferring of nervous system messages between various parts of the brain and the spinal cord.

The brainstem includes three piecesthe midbrain pons and medulla oblongata. The pons is a portion of the brain stem located above the medulla oblongata and below the midbrain. Ventral basilar part - The basilar ventral part has a uniform structure throughout length of pons.
