Immunology is the branch of biological and medical sciences that studies the immune system, which is the body’s defense mechanism against harmful organisms, pathogens (like bacteria, viruses, fungi, and parasites), and other foreign substances. Immunologists work to understand how the immune system functions in both health and disease, including autoimmune disorders, hypersensitivities (like allergies), immunodeficiencies, … Read more
What are Dendrites? Definition of Dendrites Dendrites are branched extensions of neurons that receive and process incoming signals from other neurons, facilitating communication within the nervous system. They transmit electrical impulses toward the cell body and play a crucial role in integrating synaptic inputs to generate action potentials. Characteristics features of Dendrites The following characteristics … Read more
What is Axon? Definition of Axon An axon is a long, slender projection of a nerve cell (neuron) that transmits electrical impulses, known as action potentials, away from the neuron’s cell body to other neurons, muscles, or glands, facilitating communication within the nervous system. Characteristics features of Axon Axons are vital structures in the nervous … Read more
Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. It combines principles from both biology and chemistry to study biomolecules like proteins, nucleic acids, carbohydrates, and lipids. Biochemists investigate how these molecules interact, how they contribute to the structure and function of cells, and how metabolic … Read more
What is Neuroglia? Definition of Neuroglia Neuroglia, or glial cells, are non-neuronal cells in the nervous system that provide support, insulation, and protection for neurons. They play crucial roles in maintaining homeostasis, facilitating communication, and responding to injury or disease within the central and peripheral nervous systems. Classification of Neuroglia Neuroglia, or glial cells, are … 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 Neuroscience? Neuroscience is the scientific study of the nervous system, with a central focus on the brain. It explores how the brain and the network of nerves function at both the cellular and system-wide levels. Neuroscience is a multidisciplinary field, integrating approaches from molecular biology, physiology, cognitive psychology, engineering, and artificial intelligence. The … 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
The early detection of diseases is crucial for effective treatment, and molecular diagnostics serves as a pivotal tool in this regard. This term encompasses a range of diagnostic techniques that assess an individual’s health at a molecular level. Specifically, molecular diagnostics focuses on the identification and quantification of genetic sequences—often referred to as biomarkers—found in … Read more
