The structures that are cartilaginous in humans are:

1. The larynx: This is the structure that houses the vocal cords. It is made up of nine cartilages that are connected by muscles and ligaments.

2. The outer ear: Also known as the auricle or pinna, this is the visible part of the ear that resides outside of the head. It is made of elastic cartilage.

3. The tip of the nose: The lower part of the human nose, including the tip, is made of flexible cartilage. This allows for some movement and flexibility.

The knee cap, also known as the patella, is not made of cartilage. It is a bone. Similarly, the inner ear is not made of cartilage. It is a complex structure made of bone and contains the organs of hearing and balance.
