The thyrohyoid membrane is attached below to the upper border of the thyroid cartilage and to the front of its superior cornu, and above to the upper margin of the posterior surface of the body and greater cornu of the hyoid bone. [1] It passes behind the posterior surface of the body of the hyoid.
The entire superior edge of the thyroid cartilage is attached to the hyoid bone by the thyrohyoid membrane. The thyroid cartilage is found between the levels of the C4 to C5 vertebrae. The oblique line is a line on the thyroid cartilage. It marks the upper lateral borders of the thyroid gland.
The hyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue and larynx. [1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone. [2] The hyoid apparatus resembles the shape of a trapeze, [3] or a bent letter "H".

The thyrohyoid muscle is a small skeletal muscle of the neck. 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 lateral thyrohyoid ligament (lateral hyothyroid ligament) is a round elastic cord, which forms the posterior border of the thyrohyoid membrane and passes between the tip of the superior cornu of the thyroid cartilage and the extremity of the greater cornu of the hyoid bone.
The term infrahyoid refers to the region below the hyoid bone, while the term strap muscles refers to the long and flat muscle shapes which resembles a strap. The stylopharyngeus muscle is considered by many to be one of the strap muscles, [ citation needed ] but is not an infrahyoid muscle.
The median thyrohyoid ligament (also middle hyothyroid ligament or middle thyrohyoid ligament) is the thicker, middle part of the thyrohyoid membrane. Its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the superior laryngeal nerve .
