Anatomy Of Pons

The ventral or anterior pons consists of white matter tracts eg. Descending corticospinal tracts responsible for voluntary motor control of the body.

Location And Function Of The Pons In The Human Brain

Lower down in the pons.

Anatomy of pons. The rest of the pons is made up of tracts passing through the pons including. The pons is a portion of the brain stem located above the medulla oblongata and below the midbrain. The pons is composed of two significant segments ventral pons and the tegmentum.

It is also the point of origin or termination for four of pons portion of the brain lying above the medulla oblongata and below the cerebellum and the cavity of the fourth ventricle. Ascending medial lemniscus tracts. The basilar pons and the pontine tegmentum contain nuclei and tracts.

Anterior and lateral corticospinal corticobulbar and corticopontine tracts with transverse fibres contributing to the bulk of the pons. Ascending medial lemniscus tracts. Anatomy of the pons.

The pons like the cerebellum is another metencephalic derivative of the rhombencephalon. The pons has a bulbous shape and has two main components the ventral pons and the dorsal tegmentum. Although it is small at approximately 25 centimeters long it serves several important.

The anterior surface of the. A number of cranial nerve nuclei are present in the pons. The pons consists of a the basilar pons in the front ventral portion and b the pontine tegmentum in the back dorsal portion.

This 25 cm long structure is aptly named for its resemblance of a bridge as it forms a communication pathway between the left and right hemispheres of the cerebellum. The pons is a broad horseshoe shaped mass of transverse nerve fibres that connect the medulla with the cerebellum. The basilar pons contains a complex combination of tracts bundles of axons and nuclei collections of cell bodies of neurons.

Contralateral loss of pain and temperature sense from the bodydue to damage to the anterolateral system spinothalamic5. Ipsilateral pain and temperature deficits from face due to damage tothe spinal trigeminal nucleus and tract4. The pons is a portion of the hindbrain that connects the cerebral cortex with the medulla oblongata.
