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. Two muscles originate along the line, the thyrohyoid muscle and inferior pharyngeal constrictor. The sternothyroid inserts along the line. Thyroid cartilage
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 ...
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.
It inserts onto the oblique line of the lamina of thyroid cartilage. [1] ... is prevented by the attachment of the sternothyroid to the thyroid cartilage. A goitre ...
Oblique line of thyroid cartilage: Ansa cervicalis: Thyrohyoid: Oblique line of the thyroid cartilage: Lower border of the body and the greater cornu of the hyoid bone: Cervical spinal nerve 1 via the hypoglossal nerve: Omohyoid (superior belly) Intermediate tendon: Hyoid bone: Superior root of ansa cervicalis Omohyoid (inferior belly) Superior ...
The cricothyroid muscle splits into two groups or parts. The oblique part travels posterolaterally and inserts onto the inferior cornu of the thyroid cartilage.The straight part travels posterosuperiorly and inserts onto the inferior margin of the lamina of the thyroid cartilage.
The bottom line. The key takeaway from this new research is that even small, consistent increases in physical activity—like walking—can have a profound impact on health and longevity, says Dr ...
The pyramidal lobe is a remnant of the thyroglossal duct, which usually wastes away during the thyroid gland's descent. [5] Small accessory thyroid glands may in fact occur anywhere along the thyroglossal duct, from the foramen cecum of the tongue to the position of the thyroid in the adult. [4]
