Break Down the Problem

1. Identify the external portions of the nose.
2. Determine the type of tissue that primarily constitutes those portions.

Relevant Concepts

• The nose comprises various types of tissues, including cartilage, bone, and skin.
• The primary types of cartilage relevant to the nose include fibrocartilage, elastic cartilage, and hyaline cartilage.

Analysis and Detail

1. The external portions of the nose refer mainly to the nasal tip, bridge, and the alae (the side of the nostrils).
2. The hyaline cartilage is primarily responsible for the structure of the external nose, providing both support and flexibility.
3. Elastic cartilage provides support while allowing flexibility, but it is found in areas like the ear and epiglottis rather than the nose.
4. Fibrocartilage is stronger and found in areas such as intervertebral discs, which are not present in the structure of the nose.
5. Compact bone and spongy bone are types of bone tissue and are found in the nasal skeleton, but they do not primarily form the external shape of the nose.

Verify and Summarize

To summarize, the external portions of the nose are mostly formed from hyaline cartilage, which offers the right balance of strength and flexibility necessary for the structure of the nose.

Final Answer

The external portions of the nose are mostly formed from hyaline cartilage.
