The artery supplies the muscles and mucosa of the larynx. [1] It forms anastomoses with its contralateral partner, and the superior laryngeal branch of the superior thyroid artery. [1] Tracheal branches. The tracheal branches are distributed on the trachea, and anastomose inferiorly with the bronchial arteries. [1] Esophageal branches
The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
The thyroid ima artery (thyroidea ima artery, arteria thyroidea ima, thyroid artery of Neubauer or the lowest thyroid artery) is an artery of the head and neck.It is an anatomical variant that, when present, supplies blood to the thyroid gland primarily, or the trachea, the parathyroid gland and the thymus gland (as thymica accessoria) in rare cases.
The carina is a cartilaginous ridge separating the left and right main bronchi that is formed by the inferior-ward and posterior-ward prolongation of the inferior-most tracheal cartilage. [2] The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra.
The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
Medially, it is in relation with the esophagus, trachea, and thyroid gland (which overlaps it), the inferior thyroid artery and recurrent laryngeal nerve being interposed; higher up, with the larynx and pharynx. Lateral to the artery, inside the carotid sheath with the common carotid, are the internal jugular vein and vagus nerve.
The thyrocervical trunk is a branch of the subclavian artery. [1] It arises from the first portion of this vessel, between the origin of the subclavian artery and the inner border of the anterior scalene muscle. It is located distally to the vertebral artery and proximally to the costocervical trunk. It is short and wide artery. [2]
A tracheostomy tube may be single or dual lumen, and also cuffed or uncuffed. A dual lumen tracheostomy tube consists of an outer cannula or main shaft, an inner cannula, and an obturator. The obturator is used when inserting the tracheostomy tube to guide the placement of the outer cannula and is removed once the outer cannula is in place.
