  2. Pyriform sinus - Wikipedia

    en.wikipedia.org/wiki/Pyriform_sinus

    The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane. [1] The fossae are involved in speech.

  3. Piriform cortex - Wikipedia

    en.wikipedia.org/wiki/Piriform_cortex

    The piriform cortex occupies a greater proportion of the overall brain and of the telencephalic brains of insectivores than in primates. The piriform cortex continues to occupy a consistent albeit small and declining proportion of the increasingly large telencephalon in the most recent primate species while the volume of the olfactory bulb ...

  4. Cranial fossa - Wikipedia

    en.wikipedia.org/wiki/Cranial_fossa

    A cranial fossa is formed by the floor of the cranial cavity. There are three distinct cranial fossae: [1] Anterior cranial fossa (fossa cranii anterior), housing the projecting frontal lobes of the brain [2] Middle cranial fossa (fossa cranii media), separated from the posterior fossa by the clivus and the petrous crest housing the temporal ...

    From left to right, Keros type I, II, and III. The Keros classification is a method of classifying the depth of the olfactory fossa. The depth of the olfactory fossa is determined by the height of the lateral lamella of the cribriform plate. Keros in 1962, classified the depth into three categories. [3]

  6. Posterior cranial fossa - Wikipedia

    The posterior cranial fossa is the part of the cranial cavity located between the foramen magnum, and tentorium cerebelli. It is formed by the sphenoid bones , temporal bones , and occipital bone .

  7. Lateral geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Lateral_geniculate_nucleus

    Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee (genu is Latin for "knee"). In humans as well as in many other primates , the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.

  9. Middle cranial fossa - Wikipedia

    en.wikipedia.org/wiki/Middle_cranial_fossa

    The middle cranial fossa is formed by the sphenoid bones, and the temporal bones. It lodges the temporal lobes, and the pituitary gland. [1] [2] It is deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior cranial fossa by the clivus and the petrous crest.
