Question

Cartilage of Santorini articulates with-
(a)Cricoid
(b)Arytenoid
(c)Thyroid
(d)None of the above

Answer 1

Hint: Cartilage, located at the ends of joints, is tough, yet flexible tissue. The cartilage is located above the circoidal lamina on the dorsal (back) side of the larynx, ring-shaped cartilage that lies near the bottom of the larynx.

Complete answer:
Two small conical nodules consisting of yellow elastic cartilage articulate with the summits of the arytenoid cartilages and serve to prolong them backward and medialward, are the corniculate cartilages (cartilages of Santorini). They are fused with the cartilage of arytenoids.
There are two primary functions for this muscle; adducting the vocal cords and closing the rima glottidis. By attaching to both arytenoid cartilages, contraction of transverse arytenoid's horizontal muscle fibers pulls the arytenoid cartilages closer together (adduction), consequentially adducting the vocal folds.

Additional Information:
The laryngeal corniculate cartilage. A tiny conical elastic cartilage nodule that surmounts the apex of each arytenoid cartilage.
The arytenoid cartilages are a pair of tiny three-sided pyramids that are connected to the vocal folds (vocal cords) that form part of the larynx. These allow and assist in the movement of the vocal cords.
So, The correct answer is “Arytenoid”.

Note: The arytenoid cartilages help to move the vocal folds, allowing tension, relaxation, or approximation, as the vocal folds move along with them, being attached to the arytenoids. Each is pyramidal or ladle-shaped in the form (arytenoid comes from Ancient Greek word) and has three surfaces, a base, and an apex.
