Superior laryngeal artery
Encyclopedia
The superior laryngeal artery accompanies the internal laryngeal branch of the superior laryngeal nerve
, beneath the Thyreohyoideus.
This artery branches from the superior thyroid artery
near its bifurcation from the external carotid artery
. It pierces the hyothyroid membrane
, and supplies the muscles, mucous membrane
, and glands of the larynx
, anastomosing with the branch from the opposite side.
Superior laryngeal nerve
The superior laryngeal nerve is a branch of the vagus nerve. It arises from the middle of the ganglion nodosum and in its course receives a branch from the superior cervical ganglion of the sympathetic....

External carotid artery
In human anatomy, the external carotid artery is a major artery of the head and neck. It arises from the common carotid artery when it bifurcates into the external and internal carotid artery.-Course:...

Hyothyroid membrane
The hyothyroid membrane is a broad, fibro-elastic layer, attached below to the upper border of the thyroid cartilage and to the front of its superior cornu, and above to the upper margin of the posterior surface of the body and greater cornua of the hyoid bone, thus passing behind the posterior...

Mucous membrane
The mucous membranes are linings of mostly endodermal origin, covered in epithelium, which are involved in absorption and secretion. They line cavities that are exposed to the external environment and internal organs...

Larynx
The larynx , commonly called the voice box, is an organ in the neck of amphibians, reptiles and mammals involved in breathing, sound production, and protecting the trachea against food aspiration. It manipulates pitch and volume...
