  2. Pharyngeal arch - Wikipedia

    en.wikipedia.org/wiki/Pharyngeal_arch

    The pharyngeal arches, also known as visceral arches, are transient structures seen in the embryonic development of humans and other vertebrates, that are recognisable precursors for many structures. [1] In fish, the arches support the gills and are known as the branchial arches, or gill arches.

  3. Splanchnocranium - Wikipedia

    en.wikipedia.org/wiki/Splanchnocranium

    The splanchnocranium (or visceral skeleton) is the portion of the cranium that is derived from pharyngeal arches. Splanchno indicates to the gut because the face forms around the mouth, which is an end of the gut. [1] The splanchnocranium consists of cartilage and endochondral bone.

  4. Special visceral efferent fibers - Wikipedia

    en.wikipedia.org/wiki/Special_visceral_efferent...

    Special visceral efferent fibers (SVE) are the efferent nerve fibers that provide motor innervation to the muscles of the pharyngeal arches in humans, and the branchial arches in fish. [ 1 ] Some sources prefer the term "branchiomotor" [ 2 ] or "branchial efferent".

  5. Splanchnology - Wikipedia

    en.wikipedia.org/wiki/Splanchnology

    In anatomy, a viscus is an internal organ, and viscera is the plural form. Organs consist of different tissues, one or more of which prevail and determine its specific structure and function. Functionally related organs often cooperate to form whole organ systems. Viscera are the soft organs of the body.

  6. Aortic arches - Wikipedia

    en.wikipedia.org/wiki/Aortic_arches

    The first and second arches disappear early. A remnant of the 1st arch forms part of the maxillary artery, [3] a branch of the external carotid artery. The ventral end of the second develops into the ascending pharyngeal artery, and its dorsal end gives origin to the stapedial artery, [3] a vessel which typically atrophies in humans [4] [5] but persists in some mammals.

  7. Branchial arch - Wikipedia

    en.wikipedia.org/wiki/Branchial_arch

    Branchial arches or gill arches are a series of paired bony/cartilaginous "loops" behind the throat (pharyngeal cavity) of fish, which support the fish gills. As chordates , all vertebrate embryos develop pharyngeal arches , though the eventual fate of these arches varies between taxa .

  8. Tongue - Wikipedia

    en.wikipedia.org/wiki/Tongue

    The hypopharyngeal eminence develops mainly by the growth of endoderm from the third pharyngeal arch. The boundary between the two parts of the tongue, the anterior from the first arch and the posterior from the third arch is marked by the terminal sulcus. [13] The terminal sulcus is shaped like a V with the tip of the V situated posteriorly.

  9. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
