Stratified Squamous Epithelium Stratified Squamous Epithelium Definition: The stratified squamous epithelium is the tissues which are formed by multiple layers of cells on resting basement membrane with superficial layer contain squamous cells. Underlying cell layers can compose of cuboidal or columnar cells. Types of Stratified Squamous Epithelial: These stratified squamous epithelia can be classified as keratinized or non-keratinized… Read More »

Simple Squamous Epithelium Simple Squamous Epithelium Definition: Simple squamous epithelium is the tissue that creates from one layer of squamous cells which line surfaces. The squamous cells are thin, large, and flat, and consisting of around nucleus. These tissues have polarity like other epithelial cells and consist of a distinct apical surface with special membrane proteins. Functions of… Read More »

Digastric Muscle Digastric Muscle Definition: The digastric muscle is the muscle consisting of separate muscle bellies. These two parts are separate by the intermediate rounded tendon which runs by the hyoid bone. They lie on each side of the jaw which connects from the jaw by the hyoid to the lower part of the skull. This arrangement permits… Read More »

Glycolysis Introduction of Glycolysis: Glycolysis is a process in which glucose divided into two pyruvate molecules. However, it is assumed as a linear pathway of ten enzyme meditation steps. This pathway has two stages or phases; the energy investment phase and the energy generation phase. In it, the first five steps out of ten are Energy Investment Phase… Read More »

Glycogenolysis Glycogenolysis Definition: What is Glycogenolysis: Glycogenolysis is basically a regulated process that occurs to play during a period of lack of glucose (i.e. hypoglycemia) or accelerated glucose utilization. It is used for a short period of fasting as a meal after one night sleeping. It is controlled by hormones. It breaks down the molecule of glycogen into glucose.… Read More »

Gluconeogenesis Gluconeogenesis Definition What is Gluconeogenesis: Gluconeogenesis means that “the production of new glucose”. Gluconeogenesis (GNG) is a metallic pathway that generates glucose from non-carbohydrate carbon substrate including glycerol, lactate, and glucogenic amino acid. It occurs around 8 hours of fasting when liver glycogen stores deplete continually and alternative source of glucose is needed. It occurs in the… Read More »
