LIPOPROTEINS IN BLOOD
Introduction Lipoproteins are complex molecules made up of lipids (fats) and proteins. They are responsible for transporting lipids through the bloodstream, which is important for providing energy to cells and for the synthesis of hormones and other molecules. There are…
THERMIONIC EMISSION PROCESS
Thermionic emission refers to the process by which electrons are emitted from a heated surface or material. This process is driven by the thermal energy of the material, which excites the electrons to a point where they can overcome the…
ENERGY QUANTIZATION EXPLAINED
Introduction Energy quantization refers to the idea that energy can only exist in discrete units or quanta, rather than being continuous. This concept is a fundamental aspect of quantum mechanics, which is a branch of physics that describes the behavior…
HISTOLOGY OF SALIVARY GLANDS AND PANCREAS
Introduction Salivary Glands: The salivary glands are exocrine glands that produce and secrete saliva. There are three main types of salivary glands: parotid, submandibular, and sublingual. The histology of these glands is similar, with some differences in the size and…
PANCREAS EXPLAINED
Introduction The pancreas is an important organ located in the abdomen, behind the stomach. It has both exocrine and endocrine functions. Exocrine Function: The exocrine function of the pancreas involves the secretion of digestive enzymes that help break down food…
MATTER STRUCTURE OVERVIEW
The structure of matter refers to the physical arrangement of atoms and molecules that make up all substances in the universe. Atoms are the smallest units of matter and are made up of protons, neutrons, and electrons. The protons and…
ELECTRICAL CONDUCTION THROUGH MATERIALS
Introduction Electrical conduction is the movement of charged particles, such as electrons or ions, through a material in response to an electric field. In electronic materials, such as metals, semiconductors, and insulators, the nature of electrical conduction is determined by…
WAVE-PARTICLE PARADOX
Introduction The wave-particle paradox in physics is a phenomenon that describes the dual nature of matter and energy. It refers to the observation that particles, such as electrons and photons, exhibit properties of both waves and particles. On one hand,…
DECREASED GROWTH (ATROPHY)
Progressive Atrophy is a medical condition that refers to the gradual loss of muscle mass, tissue, or function due to the degeneration of cells. It can affect any tissue or organ in the body and can be caused by a…
DECREASED GROWTH (HYPOPLASIA)
Developmental Hypoplasia is a medical term that refers to underdevelopment or incomplete development of a tissue or organ. It occurs when the cells in a particular tissue or organ do not grow or divide normally during fetal development or childhood.…
DECREASED GROWTH (AGENESIS)
Developmental Agenesis is a medical term used to describe the complete or partial absence or underdevelopment of a body part or organ. Agenesis can occur during embryonic development, resulting in the failure of a particular organ or body part to…
GENOME ORGANIZATION LEVELS
The genome is the complete set of genetic instructions, including all of the DNA, necessary to build, maintain, and reproduce an organism. The organization of the genome is a hierarchical structure that includes several levels of organization, each with its…
