Anatomical terminology

The ileocolic lymph nodes, from ten to twenty in number, form a chain around the ileocolic artery, but tend to subdivide into two groups, one near the duodenum and the other on the lower part of the trunk of the artery. Where the vessel divides into its terminal branches the chain is broken up into several groups:

Ileocolic artery

The ileocolic artery is the lowest branch arising from the concavity of the superior mesenteric artery.

Duodenum first section of the small intestine

The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum. In mammals the duodenum may be the principal site for iron absorption.

Cecum pouch that is considered to be the beginning of the large intestine

The cecum or caecum is an intraperitoneal pouch that is considered to be the beginning of the large intestine. It is typically located on the right side of the body.

Ileum The final section of the small intestine in mammals, reptiles, birds and some other vertebrates.

The ileum is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine may be used instead of ileum.

Appendix (anatomy) blind-ended tube connected to the cecum, from which it develops embryologically

The appendix is a finger-like, blind-ended tube connected to the cecum, from which it develops in the embryo. The cecum is a pouchlike structure of the colon, located at the junction of the small and the large intestines.

Large intestine last part of the digestive system in vertebrate animals, including the cecum, colon, rectum, and anal canal

The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation.

Lingual tonsils

The lingual tonsils are two small mounds of lymphatic tissue located at the back of the base of the tongue, one on either side. They are composed of lymphatic tissue that functions to assist the immune system in the production of antibodies in response to invading pathogenic bacteria or viruses.

Ascending colon the part of the colon located between the cecum and the transverse colon

The ascending colon is the part of the colon located between the cecum and the transverse colon.

Right colic artery

The right colic artery arises from about the middle of the concavity of the superior mesenteric artery, or from a stem common to it and the ileocolic.

Inferior thyroid artery Artery of the neck

The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle. It then turns medially behind the carotid sheath and its contents, and also behind the sympathetic trunk, the middle cervical ganglion resting upon the vessel.

Intestinal arteries

The intestinal arteries arise from the convex side of the superior mesenteric artery. They are usually from twelve to fifteen in number, and are distributed to the jejunum and ileum.

Midgut

The midgut is the portion of the embryo from which most of the intestines develop. After it bends around the superior mesenteric artery, it is called the "midgut loop". It comprises the portion of the alimentary canal from the end of the foregut at the opening of the bile duct to the hindgut, about two-thirds of the way through the transverse colon.

Anterior cecal artery

The anterior cecal artery is a branch of the ileocolic artery which supplies the anterior region of the cecum.

Appendicular artery

The appendicular artery commonly arises from terminal branch of the ileocolic artery less commonly from the posterior cecal artery or an ileal artery. It descends behind the termination of the ileum and enters the mesoappendix of the vermiform appendix. It runs near the free margin of the mesoappendix and ends in branches which supply the appendix.

Testicular artery branch of the abdominal aorta that supplies blood to the testis

The testicular artery is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes.

Solitary lymphatic nodule

The Solitary lymphatic nodules are structures found in the small intestine and large intestine.

Colic branch of ileocolic artery

The colic branch of ileocolic artery is a small artery in the abdomen. The ileocolic artery of the superior mesenteric artery branches off into the ascending colic artery, the anterior and posterior cecal arteries, the appendicular artery, and the ileal branches.

Superior mesenteric lymph nodes

The superior mesenteric lymph nodes may be divided into three principal groups:

Mesocolic lymph nodes

The mesocolic lymph nodes are numerous, and lie between the layers of the transverse mesocolon, in close relation to the transverse colon; they are best developed in the neighborhood of the right and left colic flexures.

Mesenteric lymph nodes

The mesenteric lymph nodes are one of the three principal groups of superior mesenteric lymph nodes and lie between the layers of the mesentery.

Human digestive system Ty mamam en tangahat are responsible for digestive function

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has many stages. The first stage is the cephalic phase of digestion which begins with gastric secretions in response to the sight and smell of food. The next stage starts in the mouth.

<i>Grays Anatomy</i> English-language textbook of human anatomy

Gray's Anatomy is an English language textbook of human anatomy originally written by Henry Gray and illustrated by Henry Vandyke Carter. Earlier editions were called Anatomy: Descriptive and Surgical, Anatomy of the Human Body and Gray's Anatomy: Descriptive and Applied, but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy. The book is widely regarded as an extremely influential work on the subject, and has continued to be revised and republished from its initial publication in 1858 to the present day. The latest edition of the book, the 41st, was published in September 2015.
