Anatomy of pons. Descending corticospinal tracts responsible for voluntary motor control of the body. Lower down in the pons. The pons is a broad horseshoe shaped mass of transverse nerve fibres that connect the medulla with the cerebellum.

Anatomy of the pons. The chief or pontine nucleus of the trigeminal nerve sensory nucleus v. Ascending medial lemniscus tracts.

Although it is small at approximately 25 centimeters long it serves several important. Pons anatomy internal anatomy. The pons like the cerebellum is another metencephalic derivative of the rhombencephalon.

Descending corticobulbar tracts responsible for voluntary motor control of face head and neck. A number of cranial nerve nuclei are present in the pons. Anterior and lateral corticospinal corticobulbar and corticopontine tracts with transverse fibres contributing to the bulk of the pons.

The pons is a portion of the hindbrain that connects the cerebral cortex with the medulla oblongata. The basilar pons contains a complex combination of tracts bundles of axons and nuclei collections of cell bodies of neurons. 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 basilar pons and the pontine tegmentum contain nuclei and tracts. Ipsilateral pain and temperature deficits from face due to damage tothe spinal trigeminal nucleus and tract4.

It also serves as a communications and coordination center between the two hemispheres of the brain. The ventral or anterior pons consists of white matter tracts eg. Facial nerve nucleus.

The rest of the pons is made up of tracts passing through the pons including. Ascending medial lemniscus tracts. Contralateral loss of pain and temperature sense from the bodydue to damage to the anterolateral system spinothalamic5.

The pons has a bulbous shape and has two main components the ventral pons and the dorsal tegmentum. The pons is a portion of the brain stem located above the medulla oblongata and below the midbrain. 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.
