What are crypts in colon?

Tube-like gland found in the lining of the colon and rectum. Colon crypt cells renew the lining of the intestine and make mucus. Also called gland of Lieberkuhn.

What is Paneth?

Paneth cells are highly specialized secretory epithelial cells located in the small intestinal crypts of Lieberkühn. The dense granules produced by Paneth cells contain an abundance of antimicrobial peptides and immunomodulating proteins that function to regulate the composition of the intestinal flora.

What are Kulchitsky cells?

Enterochromaffin (EC) cells (also known as Kulchitsky cells) are a type of enteroendocrine cell, and neuroendocrine cell. They reside alongside the epithelium lining the lumen of the digestive tract and play a crucial role in gastrointestinal regulation, particularly intestinal motility and secretion.

What does the Enteroendocrine cells secrete?

Enteroendocrine cells are hormone-producing cells that are sprinkled throughout the gut epithelium. In response to chemical and mechanical stimuli, these cells secrete a variety of important hormones, such as GLP-1 and GLP-2, PYY, CCK, and serotonin.

What are L cells?

L cell. L cells secrete glucagon-like peptide-1, an incretin, peptide YY3-36, oxyntomodulin and glucagon-like peptide-2. L cells are primarily found in the ileum and large intestine (colon), but some are also found in the duodenum and jejunum.

What are Peyer's patches?

Lymphoid follicles are small organs in your lymphatic system that are similar to lymph nodes. ... Peyer's patches play an important role in immune surveillance of materials within your digestive system.

What are enterocytes?

Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes. Microvilli on the apical surface increase its surface area.

Do intestinal cells undergo mitosis?

You might therefore need to explain that most specialized cells cannot undergo mitosis. ... Skin cells, red blood cells or gut lining cells cannot undergo mitosis. Stem cells do divide by mitosis and this makes them very important for replacing lost or damaged specialized cells.

Which cells can undergo mitosis?

Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.

Which cells do not reproduce?

Permanent cells are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non-proliferative in postnatal life. This includes neurons, heart cells, skeletal muscle cells and red blood cells.

Why do gut cells divide frequently?
