Which nerve is related to inferior thyroid artery?

the recurrent laryngeal nerve
At the inferior pole of the thyroid gland, the recurrent laryngeal nerve is closely related to the inferior thyroid artery.

Does recurrent laryngeal nerve supply thyroid?

The left recurrent laryngeal nerve comes from the left vagus nerve, loops posteriorly around the arch of the aorta, and ascends in the tracheoesophageal groove posterior to the left lobe of the thyroid, where it enters the larynx and innervates the musculature in a similar fashion as the right nerve.

Is inferior laryngeal nerve same as recurrent?

The recurrent laryngeal nerve (RLN), also known as the inferior laryngeal nerve, is a branch of the vagus nerve (CN X) which has a characteristic loop around the right subclavian artery on the right and the aortic arch on the left before returning up to achieve the tracheoesophageal groove and then the larynx.

What does the inferior laryngeal nerve innervate?

Inferior laryngeal branch of the recurrent laryngeal nerve: excluding the cricothyroid muscle [innervated by the superior laryngeal nerve], the inferior laryngeal branch of the recurrent laryngeal nerve innervates all intrinsic muscles of the larynx.

What nerve innervates the thyroid?

the vagus nerve
The parasympathetic division of the autonomic nervous system is the primary innervation of the thyroid gland, via the vagus nerve (CNX).

Where does the recurrent laryngeal nerve run?

The vagus nerves run down into the thorax, and the recurrent laryngeal nerves run up to the larynx. The vagus nerves, from which the recurrent laryngeal nerves branch, exit the skull at the jugular foramen and travel within the carotid sheath alongside the carotid arteries through the neck.

What does inferior thyroid artery supply?

The inferior thyroid artery is considered the principal blood supplier of the thyroid gland. The ITA gives rise to the ascending cervical artery, the inferior laryngeal artery, and also gives pharyngeal, tracheal, and esophageal branches. Also of importance, the ITA supplies the four parathyroid glands.

What is the origin of inferior thyroid artery?

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.

Where does the inferior thyroid artery come from?

Where is the recurrent laryngeal nerve?

The recurrent laryngeal nerves branch off the vagus, the left at the aortic arch, and the right at the right subclavian artery. The left RLN passes in front of the arch, and then wraps underneath and behind it. After branching, the nerves typically ascend in a groove at the junction of the trachea and esophagus.

What nerve is near the thyroid gland?

The two nerves of importance that pass through the thyroid are the left and right recurrent laryngeal nerves [RLN]. They are often located on the lateral aspect of the thyroid gland near the vicinity of the inferior thyroid artery.

Is the thyroid inferior to the larynx?

In its anatomic position, the thyroid gland lies posterior to the sternothyroid and sternohyoid muscles, wrapping around the cricoid cartilage and tracheal rings. It is located inferior to the laryngeal thyroid cartilage, typically corresponding to the vertebral levels C5-T1.

Is the recurrent laryngeal nerve related to the inferior thyroid artery?

Table 2demonstrates the relationship of the recurrent laryngeal nerve (RLN) to the inferior thyroid artery (ITA) on the right and left side. The RLN was observed as either related anteriorly, posteriorly, or in between the ITA.

Does intraoperative nerve monitoring reduce recurrent laryngeal nerve injury in thyroid reoperations?

Barczynski M, Konturek A, Pragacz K, Papier A, Stopa M, Nowak W. Intraoperative nerve monitoring can reduce prevalence of recurrent laryngeal nerve injury in thyroid reoperations: results of a retrospective cohort study. World J Surg. 2014;38(3):599–606. doi: 10.1007/s00268-013-2260-x.

What does the recurrent laryngeal nerve innervate?

The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (CN X). It carries sensory, motor, and parasympathetic fibers to the laryngeal structures [1]. It is the main motor nerve of all intrinsic laryngeal muscles, except the cricothyroid, which receives its innervation via the external laryngeal nerve [1].

What is left nonrecurrent inferior laryngeal nerve?

A left nonrecurrent inferior laryngeal nerve is even more uncommon, requiring the aortic arch be on the right side, accompanied by an arterial variant which prevents the nerve from being drawn into the chest by the left subclavian. : 10, 48
