What is Homeostasis? Definition of Homeostasis Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes, ensuring optimal functioning of physiological systems. This involves regulating various parameters such as temperature, pH, and ion concentrations through feedback mechanisms that include receptors, control centers, and effectors. Components and Process of Homeostasis … Read more
What is Endocrine System? Definition of Endocrine System The endocrine system is a network of glands that release hormones directly into the bloodstream to regulate various bodily functions, including metabolism, growth, reproduction, and mood. It works in conjunction with the nervous system to maintain homeostasis and coordinate complex processes within the body. Structure of Endocrine … Read more
What is Thymus Gland? Definition of Thymus Gland The thymus gland is an important organ of the lymphatic system located in the chest behind the breastbone. It plays a crucial role in the development and maturation of immune cells known as T cells, which are essential for the body’s immune response. The thymus gland is … Read more
What is Hypothalamus? Definition of Hypothalamus The hypothalamus is a small but crucial part of the vertebrate brain located beneath the thalamus. It regulates various physiological functions, including body temperature, hunger, thirst, and circadian rhythms, by linking the nervous system to the endocrine system through the pituitary gland. Additionally, it plays a role in controlling … Read more
What is Synapse? Definition of Synapse A synapse is a junction between two neurons or between a neuron and an effector cell, such as a muscle cell, that allows for the transmission of electrical or chemical signals. It consists of a presynaptic terminal, a synaptic cleft, and a postsynaptic terminal, facilitating communication within the nervous … Read more
What is Neuron? Definition of Neuron A neuron is a specialized cell in the nervous system that receives, processes, and transmits information through electrical and chemical signals. How Do Neurons Work? Neurons communicate through a combination of electrical impulses and chemical signals, ensuring efficient information transfer throughout the body. By facilitating the rapid transmission of … Read more
What is Nervous System? Definition of Nervous System The nervous system is a complex network of cells and tissues that coordinates and regulates the activities of an organism by transmitting electrical signals between different parts of the body. Cells of the Nervous System Neurones Glial Cells Astrocytes Oligodendrocytes Microglia Ependymal cells Nervous System Structure and … Read more
What is Recombinant DNA Technology? Definitions of Recombinant DNA Technology Recombinant DNA technology is a method used to manipulate and combine DNA from different sources to create new genetic combinations. It involves inserting genes from one organism into the DNA of another, allowing for the production of specific proteins or traits not naturally found in … Read more
Tissue Culture is the term used to describe the process of removing tissues, cells or organs from either a plant or animal and their subsequent transfer into an artificial environment that encourages development.
What are Silent mutations? Definition of Silent mutations Silent mutations are genetic changes in the DNA sequence that do not alter the amino acid sequence of a protein, resulting in no effect on the protein’s function or the organism’s phenotype. Cause of Silent Mutation Silent mutations are genetic changes that do not alter the final … Read more
