Autonomic innervation of the large intestine of Bufo marinus is as follows: (1) The 9th and 10th spinal nerves (pelvic) contain predominantly excitatory preganglionic cholinergic fibres, but some inhibitory adrenergic fibres are also present in most preparations. The cecum is the most proximal part of the large intestine and is located between the ileum (distal small bowel) and the ascending colon.. Having served as a site for cellulose digestion in our ancestors, the cecum now simply acts as a reservoir for chyme which it receives from the ileum..
