auricular operculum

Examples of auricular operculum in the following topics:

• Characteristics and Evolution of Amphibians

  • Amphibians also have an auricular operculum, which is an extra bone in the ear that transmits sounds to the inner ear.

• Veins of the Head and Neck

  • The superficial external jugular vein is formed from the retro-mandibular vein and the posterior auricular vein at a point adjacent to the mandible.
  • The veins of head and neck are labeled in blue, with an arrow pointing to the auricular vein.

• Cervical Plexus

  • Great auricular nerve - The great auricular nerve originates from the cervical plexus, composed of branches of spinal nerves C2 and C3.

• Function and Physiology of the Spinal Nerves

  • These include the greater occipital nerve which provides sensation to the back of the head, the lesser occipital nerve which provides sensation to the area behind the ears, the greater auricular nerve, and the lesser auricular nerve.

• Vagus (X) Nerve

  • It also has some afferent fibers that innervate the inner (canal) portion of the outer ear, via the auricular branch (also known as Alderman's nerve) and part of the meninges.

• Gnathostomes: Jawed Fishes

  • Water is drawn over gills that are located in chambers covered and ventilated by a protective, muscular flap called the operculum.

• Rhinoplasty

  • The autologous grafts usually are harvested from the nasal septum, but, if it has insufficient cartilage (as can occur in a revision rhinoplasty), then either a costal cartilage graft (from the rib cage) or an auricular cartilage graft (concha from the ear) is harvested from the patient's body.
