How Do You Spell CRICOTHYROID JOINT?

1. The cricothyroid joint is a small, synovial joint located in the anterior part of the neck, connecting the cricoid cartilage with the thyroid cartilage. It is classified as a diarthrodial joint, meaning it allows for free movement between the articulating bones.

   The cricothyroid joint is responsible for the rotational and tilting movements of the thyroid cartilage over the cricoid cartilage. This movement is vital for adjusting the tension and length of the vocal cords, ultimately controlling the pitch and quality of the voice during speech and singing.

   The joint consists of a limiting articular capsular ligament, which surrounds and stabilizes the joint, and a small synovial cavity filled with synovial fluid that lubricates the joint surfaces. The articular surfaces of the cricoid and thyroid cartilages are covered with hyaline cartilage, reducing friction during movement.

   Formation of this joint involves the posterior part of the inferior horn of the thyroid cartilage articulating with the corresponding part of the cricoid cartilage. The joint is supported by several ligaments including the cricothyroid ligament and cricothyroid membrane.

   Pathological conditions, such as inflammatory arthritis or trauma, can affect the cricothyroid joint, causing pain, swelling, and restricted movement. In rare cases, joint pathologies may lead to voice changes or difficulties in speech production. Surgical interventions may be necessary in severe cases to restore joint functionality and viability.

2. Articulatio cricothyreoidea, articulation between the inferior cornu of the thyroid and the side of the cricoid cartilage on either side.

Common Misspellings for CRICOTHYROID JOINT

The word "cricothyroid" is derived from two main components: "crico-" and "thyroid", combined with the term "joint".

The prefix "crico-" originates from the Greek word "krikos", which means "ring", referring to the cricoid cartilage. The cricoid cartilage is a ring-shaped structure located at the base of the larynx (voice box).

The term "thyroid" comes from the Greek word "thyreoeidēs", which means "shield-shaped". It refers to the thyroid cartilage, a large shield-like structure that forms the front part of the larynx.

When these two components are combined, they form "cricothyroid", which primarily describes the joint that connects the cricoid and thyroid cartilages. This joint allows for the movement and tension adjustment of the vocal cords, affecting voice pitch and tone.
