, but separated from it below by a narrow fissure; its superior margin is attached to the nasal bone and the frontal process of the maxilla

Maxilla

The maxilla is a fusion of two bones along the palatal fissure that form the upper jaw. This is similar to the mandible , which is also a fusion of two halves at the mental symphysis. Sometimes The maxilla (plural: maxillae) is a fusion of two bones along the palatal fissure that form the upper...

; its inferior margin is connected by fibrous tissue with the greater alar cartilage

Greater alar cartilage

The greater alar cartilage is a thin, flexible plate, situated immediately below the lateral nasal cartilage, and bent upon itself in such a manner as to form the medial wall and lateral wall of the naris of its own side....

.

Where the lateral cartilage meets the greater alar cartilage, the lateral cartilage often curls up, to join with an inward curl of the greater alar cartilage. That curl of the inferior portion of the lateral cartilage is called its "scroll."
