Question
**Text Transcription for Educational Website:** 2. Describe the major divisions and subdivisions of the nervous system. 3. Identify the following parts on an image of a drawing or model of a neuron: - Dendrite - Soma (cell body) - Nucleus - Axon hillock - Axon - Schwann cell - Myelin sheath - Node of Ranvier (myelin sheath gap) - Axon terminals **Image Description:** The image contains a detailed illustration of a neuron. The neuron includes: - The **cell body (soma)**, which houses the **nucleus**. - Several **dendrites** extending from the cell body. - An **axon** projecting from the cell body and traveling away, appearing segmented. - **Myelin sheaths** covering segments of the axon, interspersed with **Nodes of Ranvier** where the axon membrane is exposed. - At the end, **axon terminals** extend from the axon. 4. Identify the following structures on a histological image of a multipolar neuron, longitudinal section of myelinated axons, and cross-section of an axon. Not all structures are present on every histological image. - Dendrites - Soma (cell body) - Axon - Axon hillock - Schwann cell - Myelin sheath - Multipolar neuron - Nucleolus - Nucleus - Node of Ranvier - Myelinated axon - Unmyelinated axon

Expert Solution
Step 1: Introduce about the nervous system

The nervous system in human body is an organ system that coordinates the functioning of all the systems of the body and helps the body to respond to external stimuli. The main components of nervous system include neurons which are the cells of the nervous system that are responsible for generation and transmission of nerve impulses and neuroglia cells which perform the structural and nutritional functions.
