Prevertebral fascia

- fixed above to base of skull and below behind the oesophagus into the posterior mediastinal cavity. descends in front of longus coli muscle
- in front of scalene muscle. forms a sheath for brachial nerves, subclavian artery, vein in the posterior triangle of neck. continues under the clavical as axillary sheath and attached to deep surface of coracoclavicular fascia.
it becomes prolonged over the artery below the clavicle as the axillary sheath. It does not invest the subclavian or axillary vein; these lie in loose areolar tissue anterior to it, free to dilate during times of increased venous return from the upper limb. The fascia is pierced by the four cutaneous branches of the cervical plexus (great auric ular, lesser occipital, transverse cervical and supraclavic ular nerves). The purpose of the prevertebral fascia is to provide a fixed basis on which the pharynx, oesophagus and carotid sheaths can glide during neck movements and swallowing, undisturbed by any movements of the prevertebral muscles.

2: has a well defined anatomical sphincter at its lower end just below the diaphragm.
3: is drained by systemic veins only.
4: is constricted to some extent by the right main bronchus.
TFFF
The motor innervation to the oesophagus is via the vagus nerves (1 true). The left vagus supplies the anterior surface, the right the posterior surface. The upper striated muscle receives its nerve supply from the nucleus ambiguus within the medulla and runs via the cranial root of the accessory to the vagus. The smooth muscle in the lower part receives its supply via parasympathetic nerves from the dorsal motor vagal nucleus through the vagal plexus with relays in the oesophageal wall. A dense myenteric nerve plexus with abundant ganglia coordinates muscular activity. The cricopharyngeus, a striated muscle 3 to 5cm wide, closes the upper end of the oesophagus at rest, preventing inspired air entering the gut. The lower oesophageal sphincter has no defined anatomical features (2 false) but is represented by a zone of high resting pressure (10-15mm of mercury) in the lowest (intra-abdominal) segment below the diaphragm. Venous return from the upper oesophagus is to the brachiocephalic veins and from the midoesophagus via the azygos veins to vena cava. The lower oesophagus is drained by tributaries leading to the left gastric vein, emptying into the portal vein (3 false). This region of the lower oesophagus is the most important surgically relevant site of collaterals developing in portal hypertension. These submucosal varicosities can give rise to serious or fatal haemorrhage. The oesophagus crosses behind the left main bronchus at 27cm (11inches) from the incisor teeth where there is a slight constriction of oesophageal lumen (4 false).
21958 – With respect to the cervical oesophagus
1: the muscle is supplied by the recurrent laryngeal nerve
2: there is no submucosa
3: it inclines slightly to the left of midline but enters the thoracic inlet in the midline
4: external to its muscle layer is a layer of connective tissue which is firmly adherent to the prevertebral fascia

C. cricoid cartilage to the lower limit of the superior mediastinum.
D. thoracic inlet to the oesophageal hiatus of the diaphragm.
E. thoracic inlet to the limit of the superior mediastinum.
C
The oesophagus extends from the cricoid cartilage at the level of the sixth cervical vertebra to the cardiac orifice of the stomach at the level of the tenth thoracic vertebra (left seventh costal cartilage). In the adult it is approximately 25cm (10 inches) long and is normally collapsed and empty with functional sphincters at its upper and lower ends. On endoscopy the oesophagus starts below the cricopharyngeal sphincter at 15cm (6 inches) from the incisor teeth and extends to the cardiac orifice 40cm (16 inches) from the incisor teeth. It lies predominantly in the midline but inclines to the left as it descends from its cervical origin through the thorax and into the abdomen. The oesophagus is directly in front of the vertebral bodies at its origin at C6 vertebral level, and stays in contact with the vertebral bodies throughout the superior mediastinum, which extends to the lower border of T4 (level of manubriosternal joint and tracheal bifurcation) (C true). After passing behind the left main bronchus the oesophagus inclines forward away from the vertebral bodies to reach the oesophageal opening in the diaphragm at the level of T10 just to the left of the midline.
21073 – The cervical oesophagus
1: is related posteriorly to longus capitis muscle
