What is the process by which mucin leaves the goblet cell?
What is the process by which mucin leaves the goblet cell?
Goblet cells are simple columnar goblet shaped like epithelial cells that secrete gel-forming mucins, like mucin MUC5AC. The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress.
How are goblet cells formed?
Goblet cells They acquired their name for their typical goblet, cup-like, appearance formed by the mucin granulae which fill up the cytoplasm (Fig. 1). In addition to MUC2 the mucin granulae are filled with the other typical mucus components FCGBP, CLCA1, ZG16, and AGR2.
What is mucin what cell secretes mucin quizlet?
Mucous glands: found in the tongue & roof of the mouth among other places, secrete mucin. After it is secreted, mucin absorbs water and forms the sticky product mucus. Goblet cells are unicellular mucous glands.
What epithelium is associated with resistance to abrasion?
Stratified epithelia
What is the most rare epithelium?
Stratified columnar epithelium
What is the upper free surface of epithelial tissue?
The upper surface of epithelium is free, or exposed to the outside of the body or to an internal body cavity. The basal surface rests on connective tissue. A thin, extracellular layer called the basement membrane forms between the epithelial and connective tissue.
What is the clear gel inside a cell called?
Matrix
What is the microvilli function?
Microvilli are nonmotile finger-like protrusions from the apical surface of epithelial cells that function to increase the cell surface area and the efficiency of absorption.
What are the two broad classes of glands?
Glands are important organs located throughout the body. They produce and release substances that perform certain functions. Though you have many glands throughout your body, they fall into two types: endocrine and exocrine.
