Components of the Nose. The nose is composed of a skeleton covered by âthe skin-soft tissue envelopeâ. The skeleton is composed of several bones and cartilages of different shape connected together. Another very important component of the skeleton, which is inside the nose, is the nasal septum.
The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils. On average the nose of a male is larger than that of a female. The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the frontal bone. The anterior nasal spine is the thin projection of bone at the midline on the lower nasal margin, holding the cartilaginous center of the nose.
