  2. Pons - Wikipedia

    en.wikipedia.org/wiki/Pons

    The ventral pons is known as the basilar part, and the dorsal pons is known as the pontine tegmentum. [3] The ventral aspect of the pons faces the clivus, with the pontine cistern intervening between the two structures. The ventral surface of the pons features a midline basilar sulcus along which the basilar artery may or may not

  3. Medullary pyramids (brainstem) - Wikipedia

    en.wikipedia.org/wiki/Medullary_pyramids_(brainstem)

    The ventral portion of the medulla oblongata contains the medullary pyramids. These two ridge-like structures travel along the length of the medulla oblongata and are bordered medially by the anterior median fissure. They each have an anterolateral sulcus along their lateral borders, where the hypoglossal nerve emerges from.

  4. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    Localizing neurological lesions in the brainstem may be very precise, although it relies on a clear understanding on the functions of brainstem anatomical structures and how to test them. Brainstem stroke syndrome can cause a range of impairments including locked-in syndrome. Duret haemorrhages are areas of bleeding in the midbrain and upper ...

  5. Ventricular system - Wikipedia

    en.wikipedia.org/wiki/Ventricular_system

    In more detail, around the third week of development, the embryo is a three-layered disc. The embryo is covered on the dorsal surface by a layer of cells called ectoderm. In the middle of the dorsal surface of the embryo is a linear structure called the notochord. As the ectoderm proliferates, the notochord is dragged into the middle of the ...

  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. Tegmentum - Wikipedia

    en.wikipedia.org/wiki/Tegmentum

    In embryos, the tegmentum is the anterior half of the neural tube. However, for fetuses to adults, tegmentum refers only to the parts of the brain that remain relatively unchanged after development is complete, i.e. at the brain stem especially the midbrain. Other parts, on the other hand, develop further, through folding and thickening, and ...

  9. Fourth ventricle - Wikipedia

    en.wikipedia.org/wiki/Fourth_ventricle

    Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
