What artery does the inferior thyroid artery come from?
What artery does the inferior thyroid artery come from?
thyrocervical trunk
Origin. The inferior thyroid artery (Fig. 22.7) arises from the thyrocervical trunk, which branches from the subclavian artery on the pleural dome, in front and a little lateral of the vertebral artery.
Which vessels do the superior and inferior thyroid arteries arise?
The superior thyroid artery arises from the external carotid artery just below the level of the greater cornu of the hyoid bone and ends in the thyroid gland….
| Superior thyroid artery | |
|---|---|
| Branches | Hyoid artery Sternocleidomastoid artery Superior laryngeal artery Cricothyroid artery |
| Vein | superior thyroid vein |

What are the branches of the inferior thyroid artery?
The branches of the inferior thyroid artery are the inferior laryngeal, the oesophageal, the tracheal, the ascending cervical and the pharyngeal arteries. The inferior laryngeal artery climbs the trachea to the back part of the larynx under cover of the inferior pharyngeal constrictor muscle.
What are the branches of superior thyroid artery?
The artery gives off several branches that connect to glands, muscles, and other structures inside of the neck and jaw:
- Hyoid artery.
- Superior laryngeal artery.
- Sternocleidomastoid artery.
- Cricothyroid artery.
What artery does the left subclavian artery branch from?
left subclavian artery (LSA) arises as the third branch of the aortic arch after the left common carotid artery.
Where does superior thyroid artery arise from?
external carotid artery
The superior thyroid artery (STA) is considered to have a fairly persistent origin from the ventral surface of the external carotid artery (ECA), just inferior to the greater cornu of the hyoid bone, terminating in the thyroid gland. One of its major branches is the superior laryngeal artery (SLA).
How many inferior thyroid veins are there?
Description. The inferior thyroid veins appear two, frequently three or four, in number, and arise in the venous plexus on the thyroid gland, communicating with the middle and superior thyroid veins.
What is the superior laryngeal artery a branch of?
the superior thyroid artery
The superior laryngeal artery branches from the superior thyroid artery. This artery pierces the thyrohyoid membrane with the internal laryngeal nerve and helps supply the larynx.
What nerve runs with inferior thyroid artery?
the vagus nerve
The anatomical relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) is volatile (Fig. 1). The ITA usually arises from the thyrocervical trunk and supplies the thyroid gland, while the RLN, which is a mixed nerve, is one of the branches of the vagus nerve.
What is the inferior thyroid artery?
The inferior thyroid artery runs up through your neck and throat. It is considered one of the main vessels that supply blood to the thyroid gland, which is situated in the front of your neck and produces hormones that keep your body functioning, along with the superior thyroid artery.
What is the function of the superior thyroid artery?
The superior thyroid artery gives off five branches that contribute to the blood supply of the muscles and the viscera of the neck. This article will discuss the anatomy and function of the superior thyroid artery.
Where is the superior thyroid artery located in the neck?
It is located in the anterior neck, deep to the infrahyoid muscles. The superior thyroid artery gives off five branches that contribute to the blood supply of the muscles and the viscera of the neck.
What are the branches of the superior thyroid?
Besides the arteries distributed to the muscles and to the thyroid gland, the branches of the superior thyroid are: The infrahyoid branch (or hyoid artery ): a small artery that runs along the lower border of the hyoid bone beneath the thyrohyoid muscle. This artery connects with the infrahyoid branch of the opposite side.
