Intermediate Cuneiform Bone
There are three cuneiform ("wedge-shaped") bones in the human foot: * the first or medial cuneiform * the second or intermediate cuneiform, also known as the middle cuneiform * the third or lateral cuneiform They are located between the navicular bone and the First metatarsal bone, first, Second metatarsal bone, second and Third metatarsal bone, third metatarsal bones and are medial to the cuboid bone. Structure There are three cuneiform bones: # The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms. It is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal. Lateral to it is the intermediate cuneiform. It articulates with four bones: the navicular, second cuneiform, and First metatarsal bone, first and Second metatarsal bone, second metatarsals. The tibialis anterior muscle, tibialis anterior and fibularis longus muscle inserts at the medial cuneiform bone. # The intermediate c ...

Cuneiform Cartilages
In the human larynx, the cuneiform cartilages (from Latin: ''cunei'', "wedge-shaped"; also known as cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold. The cuneiforms are paired cartilages that sit on top of and move with the arytenoid cartilage, arytenoids. They are located above and in front of the corniculate cartilages, and the presence of these two pairs of cartilages result in small bulges on the surface of the mucous membrane. Covered by the aryepiglottic folds, the cuneiforms form the lateral aspect of the laryngeal inlet, while the corniculates form the posterior aspect, and the epiglottis the anterior. Function of the cuneiform cartilages is to support the vocal folds and lateral aspects of the epiglottis. They also provide a degree of solidity to the folds in which they are embedded.
