Holotopy

It is projected onto the anterior cervical region.

Skeletotopy

It is located at the level between the 4th and the 6th cervical vertebrae.

Syntopy

  • Superiorly, there is the hyoid bone
  • Posteriorly, there is the laryngopharynx
  • Laterally, there are common carotid arteries, internal jugular veins, and vagus nerves
  • Anteriorly, it is covered with muscles lying below the hyoid bone and the superior parts of the thyroid gland

Visually, the larynx can be identified by the elevation on the anterior surface of the neck, the so-called laryngeal prominence (prominentia laryngea), commonly known as the Adam’s apple. This structure is more prominent in men.

The larynx of an adult has the following borders:

  1. The superior border passes at the level of the hyoid bone, and from the side of the spine at the level of the 6th cervical vertebra.
  2. The inferior border passes at the level of the 6th cervical vertebra in the area of transition to the trachea.

The cartilaginous skeleton, on which the laryngeal muscles are located, is the basis of the larynx.

Laryngeal cartilages (cartilagines laryngis) are interconnected by ligaments. The larynx includes three single and three paired laryngeal cartilages.

Unpaired cartilages:

1. The cricoid cartilage (cartilago cricoidea), which is a ring-shaped cartilage of the laryngeal skeleton.

The laryngeal cartilages form the following joints:

1. The cricothyroid joint (articulatio cricothyroidea), which is formed by the lateral surface of the cricoid cartilage and the inferior horn of the thyroid cartilage. The thyroid cartilage is mobile and increases or decreases the tension of the vocal folds during vocalization, changing the pitch of the voice.

Laryngeal muscles

The laryngeal muscles are divided into several groups.

The external laryngeal muscles, which directly provide movement of parts of the organ.

1. These are the muscles that attach to the thyroid cartilage and bones of the skeleton:

  • The sternothyroid muscle (m. sternothyroideus)

The internal laryngeal muscles participate directly in breathing and vocalization.

They are divided into three subgroups.

Muscles that strain the vocal ligaments:

1. The cricothyroid muscle (m. cricothyroideus), which is located between the arch of the cricoid cartilage and the inferior border of the thyroid cartilage. This muscle narrows the rima glottidis.

Cricothyroid muscle (m. cricothyroideus)

2. The vocalis muscle (m. vocalis), which is the largest muscle of the vocal fold. It passes from the internal surfaces of the thyroid cartilage to the vocal process of the arytenoid cartilage. A thin elastic strip of tissue, which is directly involved in vocalization, runs along the medial border of the muscle.

Vocalis muscle (m. vocalis)
Vocalis muscle (m. vocalis)

Muscles that expand the rima glottidis:

1. The posterior crico-arytenoid muscle (m. cricoarytenoideus posterior), which goes from the cricoid cartilage to the muscular process of the arytenoid cartilage. This is the only muscle that expands the rima glottis. With its paralysis, breathing stops.

Muscles that constrict the rima glottidis:

1. The lateral crico-arytenoid muscle (m. cricoarytenoideus lateralis), which is a paired muscle that runs along the lateral surface of the cricoid cartilage and attaches to the muscular process of the arytenoid cartilage.

Lateral crico-arytenoid muscle (m. cricoarytenoideus lateralis)

3. The transverse arytenoid muscle (m. arytenoideus transversus), which connects the posterior surfaces of the arytenoid cartilages.

Transverse arytenoid muscle (m. arytenoideus transversus)
Transverse arytenoid muscle (m. arytenoideus transversus)

4. The thyro-arytenoid muscle (m. thyroarytenoideus), which passes from the internal surface of the thyroid cartilage to the lateral border of the arytenoid cartilage. During contraction, the arytenoid cartilage is displaced.

Also, the internal laryngeal muscles include the following two:

1. The ary-epiglottic muscle (m. aryepiglotticus), which passes between the apex of the arytenoid cartilage and the lateral borders of the epiglottis. This muscle is involved in the formation of the aryepiglottic ligament. It participates in swallowing, covering the laryngeal inlet so that food enters the esophagus.

Ary-epiglottic muscle (m. aryepiglotticus)
Ary-epiglottic muscle  (m. aryepiglotticus)

2. The thyro-epiglottic muscle (m. thyroepiglotticus), which is located between the internal surface of the angle of the thyroid cartilage and the lateral border of the epiglottis. It raises the epiglottis and opens the laryngeal inlet.

Thyro-epiglottic muscle (m. thyroepiglotticus)
Thyro-epiglottic muscle (m. thyroepiglotticus)

Blood supply

The larynx is supplied with blood by two major arteries:

  1. The superior laryngeal artery (а. laryngea superior), which arises from the superior thyroid artery (а. thyroidea superior), which in turn arises from the external carotid artery (a. carotis externa). The superior laryngeal artery passes through an opening in the outer part of the thyrohyoid membrane and forms a neurovascular bundle with the eponymous vein and nerve.
    Inside the larynx, the superior laryngeal artery splits into branches. The largest of them is the middle laryngeal artery (a. laryngea media), which anastomoses with the eponymous artery on the opposite side in the area of the conoid ligament.
  1. The inferior laryngeal artery (a. laryngea inferior), which is a branch of the inferior thyroid artery (a. thyroidea inferior) that arises from the thyrocervical trunk (truncus thyrocervicalis).

Venous drainage

Venous blood drains from the larynx in two ways:

  1. Through the superior thyroid vein (v. laryngea superior) into the internal jugular vein (v. jugularis interna)
  2. Through the inferior thyroid vein (v. laryngea inferior) into the brachiocephalic vein (v. brachiocephalica)

There are the superior and inferior parts of the lymph drainage:

  1. The superior part, which is located in the area of vestibular folds and laryngeal ventricles. From here, the lymph goes through the vessels along the neurovascular bundle of the larynx to the deep cervical lymph nodes located along the deep jugular vein.
  2. The inferior part, which includes lymphatic vessels under and above the cricoid cartilage, which insert into the pre-epiglottic lymph nodes. Also, part of the lymph flows into the deep cervical lymph nodes lying along the deep jugular vein.

Innervation

Innervation of the laryngeal muscles is carried out by two branches of the vagus nerve:

  1. The superior laryngeal nerve (n. laryngeus superior), which arises from the vagus nerve in the region of the nodose ganglion of the vagus nerve (ganglion nodosum n. vagi). Behind the greater horn of the hyoid bone, the superior laryngeal nerve splits into two branches: the external branch (r. externus), which innervates the cricoid muscle, the internal branch (r. internus), approaches the mucous membrane of the larynx in the form of sensitive branches.
  2. The inferior laryngeal nerves (n. laryngeus inferior s.n. recurrens), which are extensions of the right and left recurrent nerves that branch off from the vagus nerve. It innervates all internal laryngeal muscles, except the cricothyroid muscle, and provides sensitive innervation of the laryngeal mucosa in its inferior part and vocal folds. The right recurrent nerve arises from the vagus nerve at the level of the subclavian artery, and the left one arises at the site of the circumference of the aortic arch by the vagus nerve. The recurrent nerves on the right and left pass up to the larynx. Along the way, they give off numerous branches that innervate the trachea and esophagus.
  3. The sympathetic nerves of the larynx, which arise from the superior cervical sympathetic cervicothoracic (stellate) ganglion (ganglion stellatum).
