Nasal Cartilage Anatomy

It also connects the nasal bones and the lateral cartilages. Here we will discuss the anatomy of the nasal skeleton and its component bones.

Understanding Nasal Anatomy Inside View

In the upper portion of the nose the paired nasal bones attach to the frontal bone.

Nasal cartilage anatomy. Other structures inside and behind the nose help you breathe. The greater alar cartilages which form part of the cartilaginous scaffolding of the external nose each have two crura lateral and medial. The lower cartilage adds support width and height.

The bone and cartilage under the skin give the nose most of its size and shape. Found within the frontal bone each of these sinuses is triangular in shape. It helps shape the nostrils and the tip of the nose.

Learning the anatomy of the nose can help you better understand how the nose works. The upper cartilage supports the side of the nose. The septum is a thin wall made of cartilage and bone.

It divides the inside of the nose into two chambers. Cartilage is a robust and viscoelastic connective tissue that can be found in joints between bones the rib cage intervertebral discs the ear and the nose. Above and to the side superolaterally the paired nasal bones connect to the lacrimal bones and below and to the side inferolaterally they attach to the ascending processes of the maxilla upper jaw.

Skin also helps shape the nose. Theyre lined with a mucosal membrane and have small openings into the nasal cavity. A lot happens under the surface of the nose.

At the very top of the nasal anatomy is the nasopharanx which contains lymphoid tissue known as the adenoids. The upper row shows a longitudinal view of the back of the nose extending from the nasal bone to the tip of the nose. Vomeronasal cartilage also known as jacobsons cartilage connects the nasal septum the wall of cartilage that separates the two airways of the nose and the vomer bone a thin flat bone that separates the nostrils.

The two medial crura are tenuously joined in the midline and together with some intervening soft tissue form the septum mobile nasi at the most anteroinferior margin of the septal cartilage. The nasal skeleton is a combination of bone and cartilage which forms both what we can see as the external nose and the internal nasal septum which divides the two nasal cavities of the head. While more rigid and less flexible than muscle cartilage is not as stiff as bone.

This sinus is located in the body of the maxilla behind the cheek just above. The nasal cavity is a hollow space behind the nose that air flows through. An area called the choana links the nasopharanx to the left and right portions of the nasal cavity.
