Prevertebral Muscles Anatomy
1. Longus capitis muscle
2. Longus colli muscle

Muscles of Larynx Anatomy
1.
Oblique arytenoid muscles
2.
Transverse arytenoid muscles
Origin:
Arise
from the arytenoid cartilages.
Insertion:
Attach
to the opposite arytenoid cartilage.
Action: Close the inlet of the larynx by adducting the arytenoid cartilages. This narrows the rima glottidis, the space between the vocal folds.
Suprahyoid Muscles Anatomy
1.
Stylohyoid muscle
Origin:
Arises
from the styloid process of the temporal bone.
Insertion:
Attaches
to the body of the hyoid bone.
Action:
Elevates
and retracts the hyoid bone in an action that elongates the floor of the mouth.
Innervation: Facial nerve.
Intrinsic Muscles of Larynx Anatomy
1.
Cricothyroid muscle
Origin:
Arises
from the anterolateral part of the cricoid cartilage.
Insertion:
Inserts
into the inferior aspect and inferior horn of the thyroid cartilage.
Action:
Stretches
and tenses the vocal folds.
Innervation: External branch of the superior laryngeal nerve of the vagus.
