Dissection of nose
External nasal nerve; arteries of nose, left anterolateral view
The transverse part of the nasal muscle has been removed. Two branches (6,8) of the external nasal nerve are visible. These emerge through the membrane which covers the junction of the nasal bone and lateral nasal cartilage. A filament of the external nasal branch (10) of the infraorbital nerve crosses the external nasal nerves superficially. No communication was found between the nerves.
