Diet characteristics, digesta kinetics, and dry matter intake of steers grazing eastern gamagrass. From the cervical toward the thoracic segment of the esophagus the density and size of myenteric ganglia increase and nerve fiber strands exhibit thicker diameters Teixeira et al.


The cervical esophagus lay dorsal and slightly to the left of the trachea. IVITA2 1: Finger-like extensions of lamina propria, the papillary layer, interdigitated with the epithelium.

Contribution of chewing during eating and rumination as the clearance of digesta from the rumino-reticulum. The entire muscularis of the esophagus was striated muscle in two general visiologia but also with a somewhat random orientation of fibers.

In transverse frozen sections, muscle fibers were smaller in diameter and less polygonal than those in limb muscle. Nutritional limits to animal production from pastures.

L indicates the lumen of the esophagus. Persistent right aortic arch in a mature llama.

Accuracy The analytical methodology accuracy was assessed through standard addition method. Blood vessel and perimysial connective tissue density increased in the tunica muscularis of the distal segment of the esophagus.

The specimen was transferred to gauze moistened with cold saline solution and held in a Petri dish on ice prior to freezing. Services on Demand Journal. In this group those slightly larger animals with longer necks would obviously be the animals with the longer esophagus.

Method for sizing forage cell wall particles. But, inspection of the entire cross-section of the specimens revealed areas in both tunics in which an admixture of longitudinally and circularly arranged fibers was present. Breakdown of large particles in forage by simulated digestion and detrition. Nutritional ecology of the ruminant. A slight variation in muscle fiber size was found in the distal segment of the esophagus.

Myenteric ganglion cells were not readily seen except in 5 of 45 sections that were carefully examined in which ganglion cell bodies, identifiable nuclei, were found.
