− | ==Introduction==
| |
− | | |
− | The large intestine extends from the [[Ileum - Anatomy & Physiology|ileum]] of the [[Small Intestine - Anatomy & Physiology|small intestine]] to the anus. It absorbs water from the ingesta and stores faeces prior to defeacation. Every species has a large microbial population living in the large intestine, which is of particular importance to the [[Hindgut Fermenters - Anatomy & Physiology|hindgut fermenters]]. For this reason, hindgut fermenters have a more complex large intestine with highly specialised regions for fermentation.

− | ==Innervation==
| |
− | | |
− | *Like the [[Small Intestine - Anatomy & Physiology|small intestine]], the large intestine recieves sympathetic and parasympathetic innervation.
| |
− | *Neurones interact with the myenteric plexus to affect contractility, and with the submucosal plexus to affect secretions.
| |
− | **The '''sympathetic '''have coeliac, cranial mesenteric and caudal mesenteric ganglia.
| |
− | **As the sympathetic fibres leave the ganglia, they surround their respective artery.
| |
− | **'''Parasympathetic''' innervation stimulates peristalsis.

− | ==Histology==
| |
− | | |
− | *The muscosa of the large intestine is smooth; there are '''no villi'''.
| |
− | *There are numerous scattered lymph nodules.
| |
− | *Taenia may be present.
