==Introduction==

==Introducción==

The reticulum is the second chamber of the ruminant stomach. It has regular contractions which precede the biphasic ruminal contraction for digestion of food particles. Mechanical digestion and microbial fermentation occur to breakdown food particles for absorption. [[Volatile Fatty Acids|Volatile fatty acids]] are the major product of ruminant digestion.

:The secondary contraction lets gas out (see [[Eructo - Anatomía & Fisiología|eructo]]). Ingesta flows from the ventral blind sac to the dorsal blind sac then to dorsal sac (eructation) and to the ventral sac.

==Vasculature==

==Vascularización==

The reticulum receives blood supply from the '''cranial mesenteric artery''', '''celiac artery''' and '''right and left ruminal arteries'''.

==Innervation==

==Inervación==

The reticulum is innervated by the '''dorsal vagus''' ([[Cranial Nerves - Anatomía & Fisiología|CN X]]) (most important) and the '''ventral vagus''' nerve ([[Cranial Nerves - Anatomía & Fisiología|CN X]]).

==Lymphatics==

==Linfáticos==

Numerous small lymph nodes are scattered in the grooves. The lymph drains to larger atrial nodes between the cardia and [[Omaso - Anatomía & Fisiología|omaso]], then to the cistera chyli.

The reticulum is lined by a '''keratinised stratified squamous epithelium''' and there are no glands present. The characteristic honeycomb appearance is formed by the mucosal layer trown into short and tall folds. The folds gradually merge into '''papillae''', where the reticulum meets the rumen. [[Lengua - Anatomía & Fisiología#Types of Papillae|Conical papillae]], also called secondary papillae, are present on folds, providing a rough surface to increase food breakdown.

===Small Ruminants===

===Rumiantes Pequeños===

Small ruminants have a larger reticulum compared to cattle. In sheep and goats, the ridges of the reticular cells are lower and have more prominent serrated edges than in cattle. The papillated ruminal mucosa expands over a greater proportion of the reticulum.
