Splenic Artery

Splenic Artery The structure indicated is the splenic artery. The splenic artery is one of three branches of the celiac trunk, which is the first anterior branch that arises from the abdominal aorta. The abdominal aorta consists of anterior, posterior, and lateral branches. There are three anterior branches which supply the foregut, midgut and hindgut structures these are as follows: Celiac trunk – supplies foregut Superior mesenteric artery – supplies midgut Inferior mesenteric artery – supplies hindgut The celiac trunk arises from the abdominal aorta at the level of the upper part of the first lumbar vertebra. It gives rises …

Genioglossus

Genioglossus The structure indicated is the genioglossus muscle of the tongue. The genioglossus muscle is one of the extrinsic muscles of the tongue. The muscles involved with the tongue consist of intrinsic muscles which lie within the tongue itself, and the extrinsic muscles which attach to the tongue and are responsible for depression, elevation, protraction and retraction of the tongue. There are four sets of extrinsic tongue muscles: Genioglossus Hyoglossus Palatoglossus Styloglossus The genioglossus is a large muscle which extends anteriorly from the chin, to the tongue. The genioglossus is involved in depression and protrusion of the tongue. Origin: Superior …

Submandibular Gland

Submandibular Gland The structure indicated is the submandibular gland. There are three main large sets of salivary glands in the face: Parotid glands Submandibular glands Sublingual glands The submandibular glands are hook shaped and consist of a deep part and a superficial part, separated by the mylohyoid muscle. The deep part of the submandibular gland is formed from the shorter arm of the hook, which loops posteriorly around the mylohyoid muscle to enter the floor of the oral cavity. The superficial part of the submandibular gland is formed from the longer arm of the hook and lies outside the oral …

Myenteric Plexus

Myenteric Plexus The myenteric plexus, also known as Auerbach’s plexus, together with Meissner’s plexus (submucosal plexus) forms the enteric nervous system which regulates the function of the gastrointestinal system. The myenteric plexus is located between the inner and outer muscle layers of the muscularis externa. The submucosal plexus (Meissner’s plexus), on the other hand, is located in the submucosa. This diagram illustrates the four layers of the gastrointestinal tract: Mucosa – consists of 3 layers Epithelium Lamina Propria Muscularis Mucosae Submucosa – connective tissue, submucosal plexus and blood vessels/lymphatics Muscularis Externa – 3 muscle layers in the stomach, 2 in …

Soft Palate

Soft Palate The structure indicated is the soft palate. The hard and soft palates form the roof of the oral cavity. The oral cavity opens anteriorly on the face via the oral fissure. Posteriorly the oral cavity opens into the oropharynx via oropharyngeal isthmus. The floor is formed mainly of the tongue and surrounding soft tissue. Laterally, the oral cavity is bounded by the muscular cheeks. The hard palate forms the anterior portion of the roof of the oral cavity and consists of a plate of bone (from the maxilla and palatine bones) covered in mucosa. Posteriorly, the soft palate …

Splenic Artery

Splenic Artery The structure indicated is the splenic artery. The splenic artery the largest of three arteries arising for the celiac trunk: Left gastric artery Common hepatic Splenic artery The celiac artery is responsible for supplying the foregut structures, arising from the abdominal aorta just below the point at which it emerges through the aortic hiatus, at the level of vertebra L1. The splenic artery takes a tortuous course along the superior aspect of the pancreas to enter the hilum of the spleen. Along its course, it gives off several branches supplying the neck, body and tail of the pancreas. …
