  2. Pons - Wikipedia

    en.wikipedia.org/wiki/Pons

    The pons is also called the pons Varolii ("bridge of Varolius"), after the Italian anatomist and surgeon Costanzo Varolio (1543–75). [1] This region of the brainstem includes neural pathways and tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus .

  3. Pontine nuclei - Wikipedia

    en.wikipedia.org/wiki/Pontine_nuclei

    Pontocerebellar fibers are the sole efferent pathway of the pontine nuclei. The fibers mostly decussate within the pons to pass through the (contralateral) middle cerebellar peduncle to terminate in the contralateral cerebellum as mossy fibers; they form terminal synapses in the cerebellar cortex, but also issue collaterals to the cerebellar nuclei.

  4. Pontine tegmentum - Wikipedia

    en.wikipedia.org/wiki/Pontine_tegmentum

    The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons, or basilar pons. Along with the dorsal surface of the medulla oblongata, it forms part of the rhomboid fossa – the floor of the fourth ventricle.

  5. Middle cerebellar peduncle - Wikipedia

    en.wikipedia.org/wiki/Middle_cerebellar_peduncle

    The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.

  6. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    The brainstem is very small, making up around only 2.6 percent of the brain's total weight. [3] It has the critical roles of regulating heart and respiratory function, helping to control heart rate and breathing rate. [4] It also provides the main motor and sensory nerve supply to the face and neck via the cranial nerves.

  7. Basilar part of pons - Wikipedia

    en.wikipedia.org/wiki/Basilar_part_of_pons

    The basilar part of pons, also known as basis pontis, or basilar pons, is the ventral part of the pons (ventral pons) in the brainstem; the dorsal part (dorsal pons) is known as the pontine tegmentum. The basilar part of the pons makes up two thirds of the pons. [1] It has a ridged appearance with a shallow groove at the midline.

  8. Cerebellopontine angle - Wikipedia

    en.wikipedia.org/wiki/Cerebellopontine_angle

    The cerebellopontine angle (CPA) (Latin: angulus cerebellopontinus) is located between the cerebellum and the pons. [1] The cerebellopontine angle is the site of the cerebellopontine angle cistern. [2] The cerebellopontine angle is also the site of a set of neurological disorders known as the cerebellopontine angle syndrome.

  9. Corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Corticospinal_tract

    Then both tracts pass through the brain stem, from the pons and then to the medulla. [2] The corticospinal tract, along with the corticobulbar tract, form two pyramids on either side of the medulla of the brainstem—and give their name as pyramidal tracts. [1] Corticospinal neurons synapse directly onto alpha motor neurons for direct muscle ...
