HUMAN NEURON
1. Human Neuron Structure
A neuron is the basic structural and functional unit of the nervous system. It is specialized for transmitting nerve impulses throughout the body. A neuron consists of dendrites, a cell body (soma), nucleus, axon, myelin sheath, and axon terminals. Dendrites receive signals from other cells and carry them to the cell body. The nucleus controls cellular activities. The axon conducts nerve impulses away from the cell body. The myelin sheath insulates the axon and increases the speed of impulse transmission. Axon terminals pass signals to other neurons, muscles, or glands. Neurons are essential for coordination, communication, and body functions.
2. Human DNA Double Helix
DNA (Deoxyribonucleic Acid) is the hereditary material present in almost all living organisms. It has a double-helix structure consisting of two strands twisted around each other. The outer part is the sugar-phosphate backbone, while the inner part contains nitrogenous bases. Adenine pairs with Thymine, and Guanine pairs with Cytosine. DNA stores genetic informa
