    en.wikipedia.org/wiki/Sulcus_(neuroanatomy)

    In neuroanatomy, a sulcus (Latin: "furrow"; pl.: sulci) is a shallow depression or groove in the cerebral cortex. One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals .

    A sulcus is an inward fold, or valley in the brain's surface - for example the central sulcus. Additional terms used to describe these may include: Annectent gyrus, for a small gyrus hidden in the depth of a sulcus; sulcal fundus, for the bottom of a sulcus, an inward fold; A fissure is used to describe: A deep groove produced by opercularisation.

    In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain , but also in the lungs , certain muscles (including the heart ), as well as ...

  6. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    The outer ear funnels sound vibrations to the eardrum, increasing the sound pressure in the middle frequency range. The middle-ear ossicles further amplify the vibration pressure roughly 20 times. The base of the stapes couples vibrations into the cochlea via the oval window , which vibrates the perilymph liquid (present throughout the inner ...

  7. Topographic map (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Topographic_map_(neuroanatomy)

    In neuroanatomy, topographic map is the ordered projection of a sensory surface (like the retina or the skin) or an effector system (like the musculature) to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems.

  8. Gyrus - Wikipedia

    en.wikipedia.org/wiki/Gyrus

    In neuroanatomy, a gyrus (pl.: gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg. : sulcus ). [ 1 ] Gyri and sulci create the folded appearance of the brain in humans and other mammals .
