The thyroid cartilage is a hyaline cartilage structure that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple. [1] In the midline above the prominence is the superior thyroid notch. A counterpart notch ...

It is separated from the hyoid bone by a mucous bursa, which allows for the upward movement of the larynx during swallowing. [1] Its middle thicker part is termed the median thyrohyoid ligament. [1] Its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the superior laryngeal nerve. [1]
Thyroid cartilage: This forms the Adam's apple (also called the laryngeal prominence). It is usually larger in males than in females. The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects it with the hyoid bone. It supports the front portion of the larynx.
Laryngeal cartilages are cartilages which surround and protect the larynx. They form during embryonic development from pharyngeal arches. There are a total of nine laryngeal skeleton in humans: Thyroid cartilage - unpaired; Cricoid cartilage - unpaired; Epiglottis - unpaired; Arytenoid cartilages - paired; Corniculate cartilages - paired
The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane. [1] The fossae are involved in speech.
Commonly prescribed thyroid drug levothyroxine was linked with bone mass and bone density loss in a cohort of older adults in a recent study. Common thyroid drug levothyroxine linked to bone mass loss
Above, it attaches onto the greater cornu of the hyoid bone; below, it attaches onto the oblique line of the thyroid cartilage. It is innervated by fibres derived from the cervical spinal nerve 1 that run with the hypoglossal nerve (CN XII) to reach this muscle. The thyrohyoid muscle depresses the hyoid bone and elevates the larynx during ...
