The two light arytenoid cartilages are shaped like three-sided pyramids, and they lie in
the posterior aspect of the larynx
.
What are the arytenoids?
The arytenoid cartilages or arytenoids are
a pair of pyramid-shaped structures found in the voice box (larynx)
. These are located lateral to the upper border of the lamina of Adam’s apple. The arytenoid cartilage is a tough, yet flexible tissue. The arytenoids are attached to the vocal cords.
Where do the arytenoids sit?
The arytenoid cartilages, which are highly mobile, sit
on top of the lamina of the cricoid cartilage
, just to each side of the mid-line. They articulate with the cricoid cartilage at these two surfaces.
Are arytenoids anterior or posterior?
The arytenoid cartilage is attached to the cricoid ring through a series of
anterior and posterior ligaments
that form the capsule of the synovial cricoarytenoid joint.
Where is the vocal process located?
The vocal folds, also known as vocal cords, are located
within the larynx (also colloquially known as the voice box) at the top of the trachea
. They are open during inhalation and come together to close during swallowing and phonation.

How many Arytenoids are there?
Arytenoids. The
two light arytenoid
cartilages are shaped like three-sided pyramids, and they lie in the posterior aspect of the larynx.
What larynx means?
Listen to pronunciation. (LAYR-inx)
The area of the throat containing the vocal cords
and used for breathing, swallowing, and talking.
What is the main function of larynx?
Key Points
The larynx serves
to protect the lower airways, facilitates respiration
, and plays a key role in phonation. In humans the protective and respiratory functions are compromised in favor of its phonatory function.
What are the 3 parts of the larynx?
The internal space of the larynx is wide in the superior and inferior parts but narrows in the middle, forming a section named glottis, and dividing all the spaces into three sections:
supraglottic, glottis, and infraglottic
. The vocal cords, the glottis, and the larynx ventricles comprise the glottic space.
Why is the posterior cricoarytenoid muscle important?
Origin Posterior surface of cricoid lamina | Action Abducts and lengthens vocal folds, opens glottis |

Is the larynx posterior to the esophagus?
The larynx is
posterior
to the esophagus.
Is the posterior cricoarytenoid muscle bilateral?
Conclusion: The external branch of the SLN contributes to the ipsilateral posterior cricoarytenoid muscle innervation in one-third of the cases. This contribution is usually unilateral, but
is occasionally bilateral
.
Do we have two vocal cords?
The vocal cords or vocal folds are
two sets of tissue
stretched across the larynx. They can vibrate when air passes through the larynx. … Men and women have different vocal fold sizes. Adult male voices are usually deeper: males have thicker cord.
How is sound produced in the voice box?
The vocal folds (vocal cords) are attached within the larynx to the largest of the laryngeal cartilages known as the thyroid cartilage or “Adam’s apple”. The vocal folds produce
sound when they come together and then vibrate as air passes through them during exhalation of air
from the lungs.
What are the symptoms of a damaged vocal cord?
- A breathy quality to the voice.
- Hoarseness.
- Noisy breathing.
- Loss of vocal pitch.
- Choking or coughing while swallowing food, drink or saliva.
- The need to take frequent breaths while speaking.
- Inability to speak loudly.
- Loss of your gag reflex.
