Inferior horn

Inferior Horn

The Inferior Horn, also known as the Inferior Cornu, is a significant anatomical structure found in the human body. It is a part of the thyroid cartilage, which is the largest cartilage of the larynx and serves as a shield for the vocal cords.

Anatomy

The thyroid cartilage is composed of two laminae that are fused anteriorly, forming the laryngeal prominence. The inferior horn is a protrusion at the posterior end of each lamina. It articulates with the cricoid cartilage via the cricothyroid joint, allowing for movement and adjustment of the vocal cords.

Function

The primary function of the inferior horn is to provide a point of articulation for the cricoid cartilage. This articulation allows for the movement and adjustment of the vocal cords, which is crucial for speech and breathing.

Clinical Significance

Abnormalities or injuries to the inferior horn can lead to voice changes, difficulty in swallowing (dysphagia), or breathing problems. Conditions such as laryngeal cancer or laryngitis can also affect the inferior horn and the surrounding structures.
