  2. Nasal septal hematoma - Wikipedia

    en.wikipedia.org/wiki/Nasal_septal_hematoma

    The cartilage in the septum is avascular and can be 2–4 mm thick. The septum gets its blood supply from the ethmoid and sphenopalatine arteries. [4] The nasal septum is composed of cartilaginous, membranous, and bony components overlaid by mucoperichondrium and mucoperiosteum.

  3. Kiesselbach's plexus - Wikipedia

    en.wikipedia.org/wiki/Kiesselbach's_plexus

    Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.

  4. Posterior septal artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_septal_artery

    The posterior septal artery supplies blood to the respiratory region of the nasal septum, which consists of the lower two-thirds of the nasal septum and most of the nasal floor. [1] The path of the posterior septal artery can be understood by splitting it into three different segments.

  5. Nasal cavity - Wikipedia

    en.wikipedia.org/wiki/Nasal_cavity

    The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.

  6. Greater palatine artery - Wikipedia

    en.wikipedia.org/wiki/Greater_palatine_artery

    The greater palatine artery is a branch of the descending palatine artery (a terminal branch of the maxillary artery) and contributes to the blood supply of the hard palate and nasal septum. Course [ edit ]

  7. Anterior ethmoidal artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_ethmoidal_artery

    Here it bifurcates into a medial and lateral branch. The lateral branch supplies blood to the lateral wall of the nasal cavity and the medial branch to the nasal septum. A terminal branch of the lateral branch, called the external nasal branch passes between the nasal bone and the nasal cartilage to supply the skin of the nose. [citation needed]

  8. Human nose - Wikipedia

    en.wikipedia.org/wiki/Human_nose

    The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.

  9. Labyrinthine artery - Wikipedia

    en.wikipedia.org/wiki/Labyrinthine_artery

    It supplies blood to the internal ear. Structure. The labyrinthine artery is a branch of either the anterior inferior cerebellar artery (AICA) or the basilar artery.
