What is the cervical esophagus?

The cervical esophagus is the first anatomical part of the esophagus, a muscular tube that connects the pharynx to the stomach. It extends from the cricoid cartilage at the C6 vertebra level to the superior border of the manubrium sterni in the neck.

What are the key anatomical relations of the cervical esophagus?

The cervical esophagus is related anteriorly to the trachea and recurrent laryngeal nerve, posteriorly to the prevertebral fascia, longus colli muscles, and vertebral column, and laterally to the thyroid gland lobes, common carotid artery, and thoracic duct on the left side.

How is the cervical esophagus supplied with blood and drained of lymph?

The cervical esophagus is supplied by the inferior thyroid arteries, drained by the inferior thyroid veins and left brachiocephalic vein, and its lymph drains to the pretracheal and deep cervical lymph nodes.

Why is the cervical esophagus easier to access surgically from the left side?

The cervical esophagus deviates slightly to the left as it descends, making its left margin more accessible from behind the trachea, which aids in surgical access.

What is the clinical significance of the prevertebral fascia in relation to the cervical esophagus?

The prevertebral fascia acts as a movable support, allowing the esophagus and trachea to glide smoothly during activities like swallowing and phonation, maintaining function and flexibility.

How is the cervical esophagus examined in clinical practice?

The cervical esophagus is examined using an esophagoscope for endoscopy, which helps in biopsy and foreign body removal.
