==Introduction==

The oesophagus (or gullet) is a muscular tube which transports food from the [[Pharynx - Anatomy & Physiology|pharynx]] to the [[Forestomach - Anatomy & Physiology|stomach]]. A bolus of food is passed down the oesophagus by [http://en.wikipedia.org/wiki/Peristalsis| peristalsis].

The oesophagus is divided into cevical, thoracic and abdominal sections.

==Structure and Function==

[[Image:Oesophagus anatomy.jpg|thumb|right|150px|Oesophagus Anatomy - Copyright RVC 2008]]
*Begins dorsal to cricoid cartilage of [[Larynx - Anatomy & Physiology|larynx]]

*Follows trachea down neck, first on the left and then medially once in thorax in the mediastinum

*Passes over [[Heart - Anatomy & Physiology|heart]] then through the oesophageal hiatus of the diaphragm

*Passes over the dorsal border of the [[Liver - Anatomy & Physiology|liver]] then joins the [[Forestomach - Anatomy & Physiology|stomach]] at the cardia

*The cervical section is accompanied by the common carotid artery, the vagosympathetic trunk and the recurrent laryngeal nerves

*The thoracic section is accompanied by the right and left vagus nerves ([[Cranial Nerves - Anatomy & Physiology|CN X]])

*Different proportions of striated muscle across the species
**Dog and ruminant = 100%
**Cat = 80% (rostral)
**Horse = 65% (rostral)
**Pig = 33% (rostral)

==Histology==

[[Image:Oesophagus Histology.jpg|thumb|right|150px|Oesophagus Histology (Rat) - Copyright RVC 2008]]
*Stratified squamous epithelium

*Mucosal folds for distension

*Degree of keratinisation depend on diet

*Lamina propria contains collagen and elastic fibres sparsely distributed

*Lamina muscularis is smooth or skeletal muscle (depending on species)

*No glands in mucosa

*Mucous glands (tubulo-acinar) present in submucosa

*Inner circular layer of tunica muscularis thickens near gastric junction forming a sphincter

==Innervation==

*Sympathetic nerves

*Parasympathetic from the vagus nerve ([[Cranial Nerves - Anatomy & Physiology|CN X]]) and recurrent laryngeal nerves

*Myenteric plexus extends the length of the oesophagus

==Species Differences==

*Mucous glands present in horse, cats and ruminants only at pharyngeal-oesophageal junction

*Thick and strong sphincter of tunica muscularis in dogs and pigs

*Ruminants, horse and pig have stratified squamous epithelium continuing from oesophagus into [[Forestomach - Anatomy & Physiology|stomach]]. Carnivores have an abrupt transition to columnar epithelium.

===Canine===
*No keratinisation

*Lamina muscularis is skeletal muscle

*Lamina muscularis present caudally (spirally aranged)

*Lamina muscularis absent cranially

*Mucous glands throughout but more abundant caudally

===Equine===
*Some keratinisation

===Ruminant===
*Heavily keratinised

===Porcine===
*Lamina muscularis present caudally (very thick)

*Lamina muscularis absent cranially

*Some keratinisation

*Mucous glands abundant cranially but absent caudally

===Avian===
*See [[Crop- Anatomy and Physiology|the crop]]

*Ducks have an oesophangeal [[Tonsils - Anatomy & Physiology|tonsil]] present in the caudal segment of oesophagus
