The peripheral nervous system relies on nerves to transmit signals between the central nervous system and the body, with their structure featuring protective connective tissue layers and bundled axons for efficient conduction. This image, including a schematic diagram and a light micrograph (LM × 40) from simian tissue provided by the Regents of University of Michigan Medical School © 2012, illustrates key components such as the epineurium, perineurium, endoneurium, fascicle, axon, blood vessels, and spinal nerve, offering a clear view of nerve organization. Understanding these elements is fundamental to grasping how nerves maintain integrity and function in signal transmission.

Nervous tissue forms the foundation of the nervous system, enabling the transmission and processing of signals throughout the body. This article explores the anatomical structure of nervous tissue, focusing on its cellular components—neurons and neuroglia—such as astrocytes, oligodendrocytes, and microglial cells, as illustrated in a detailed diagram and a micrograph at 872x magnification. By examining the structure and physical characteristics of nervous tissue, we uncover its critical role in coordinating bodily functions, from sensory perception to motor responses.

Cartilage is a vital connective tissue in the human body, offering support, flexibility, and resilience to various structures. This article explores the three main types of cartilage—hyaline, fibrocartilage, and elastic cartilage—through detailed anatomical illustrations and microscopic views. Each type has unique properties that allow it to perform specific functions, from providing smooth joint surfaces to absorbing shock and enabling elasticity. With labeled diagrams and in-depth explanations, this guide offers a comprehensive look at cartilage structure, its physical characteristics, and its critical role in the body.

Neurons are the fundamental units of the nervous system, responsible for transmitting signals throughout the body. This article delves into the anatomical structure of a neuron, highlighting its key components such as the soma, dendrites, and axon, as illustrated in a detailed diagram and micrograph. By exploring the neuron's structure and physical characteristics, we uncover its critical role in facilitating communication within the nervous system, supported by a labeled illustration and a microscopic view at 1600x magnification.
