Human Nose Model on Base

Quick Answer: The human nose model on base is an anatomical replica of the human nose mounted on a base, used to teach the structure of the external nose and the passages it leads into. Students use it to learn how bone and cartilage shape the nose and how the septum divides it into two airways.

Bone and Cartilage of the External Nose

The shape of the external nose comes from a mixed framework. The upper third, the bridge, is bone: the paired nasal bones meeting in the midline, with the frontal processes of the maxillae on either side. The lower two thirds are cartilage: the lateral cartilages below the nasal bones and the curved alar cartilages that form the tip and surround each nostril. Fibrofatty tissue fills the outer wing, the ala. Tracing where bone stops and cartilage begins explains why the lower nose is flexible while the bridge is rigid.

Inside, the septum divides the nose into right and left cavities. Its front part is septal cartilage; behind that lie the perpendicular plate of the ethmoid and the vomer. Just inside each nostril is the vestibule, lined with skin and coarse hairs, before the lining changes to mucous membrane further in.

The model also supports practical topics: nasal fractures usually involve the thin nasal bones, and a bent septum can narrow one side of the nose. The title gives the mounting but not the scale or whether the nose model on base is sectioned, and beyond its mounting its differences from the stand-mounted version in the range are not stated.

Specifications

Applications

• Anatomy lessons on the bony and cartilaginous framework of the nose
• First-aid and sports-injury teaching on nasal fractures and swelling
• Explaining a deviated septum and one-sided nasal blockage
• Art, cosmetology and maxillofacial classes studying nasal shape

Care & Handling

• Keep the model on a flat, stable surface and lift it by the base rather than by the nose tip.
• Clean with a soft brush and a barely damp cloth, keeping moisture off any joins.
• Store it covered or boxed to protect the painted cartilage and bone boundaries from dust.

Why Choose LabEquip

Anatomy tutors and first-aid instructors use a base-mounted nose to show the framework that gives the nose its shape. LabEquip offers it among its anatomy models with the nose and olfactory organ model for the sense of smell; send any questions through the contact page.

Frequently Asked Questions

Which part of the nose is bone and which is cartilage?

The upper part of the bridge is formed by the two nasal bones and parts of the maxillae. The lower nose, including the tip and the rims of the nostrils, is shaped by cartilages, which is why it can be bent gently.

What is the vestibule of the nose?

It is the small space just inside each nostril, lined with skin and coarse hairs that trap larger particles. Beyond it, the lining changes to moist mucous membrane.

What is a deviated septum?

It is a septum that bends to one side instead of running straight down the middle. Many people have a slight deviation; a larger one can narrow one airway and cause blockage, snoring or sinus problems.

Why do broken noses often involve the nasal bones?

The nasal bones are thin and project from the face, so a direct blow tends to fracture them. The cartilage below usually bends rather than breaking.

What are the alar cartilages?

They are two curved cartilages, one on each side, that shape the tip of the nose and the rim around each nostril. Their flexibility lets the nostrils widen slightly when breathing hard.

How does the base mounting help in teaching?

A base keeps the model steady on a bench so it can be viewed from different sides without handling it, which suits displays and group work where students take turns labelling it.
