Detailed explanation-1: -Cell body, dendrites, and axon are the three distinct parts of a neuron. The cell body contains cytoplasm and nucleus. Dendrites are the smaller branches arising from the cell body. They connect with dendrites of other cells and transfer the signal.
Detailed explanation-2: -Introduction: The brain is made up of about 86 billion nerve cells (also called “neurons"). A neuron has 4 basic parts: the dendrites, the cell body (also called the “soma"), the axon and the axon terminal.
Detailed explanation-3: -Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3). Within the cell body is a nucleus (2), which controls the cell’s activities and contains the cell’s genetic material.
Detailed explanation-4: -Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites.
Detailed explanation-5: -The most common neuron types are sensory neurons, motor neurons, and interneurons. Of these, the interneurons are the most abundant neuron. Which neurons carry impulses away from the central nervous system? Efferent neurons help carry signals from the brain and central nervous system (CNS) to the muscles and skin.
