The spinal cord's microscopic cross-section reveals a highly organized structure critical for transmitting neural impulses and coordinating reflexes. This LM × 40 micrograph of a thoracic segment, provided by the Regents of University of Michigan Medical School © 2012, displays the distinctive butterfly-shaped gray matter surrounded by white matter, highlighting horns and columns essential for sensory, motor, and autonomic functions. This detailed view offers insights into the cord's cellular architecture and its role in central nervous system operations.

The spinal cord serves as a crucial conduit for neural signals between the brain and the body, with its cross-sectional anatomy revealing distinct gray and white matter regions essential for sensory and motor functions. This image of a thoracic spinal cord segment, accompanied by a microscopic view, illustrates the posterior (dorsal) horn, lateral horn, anterior (ventral) horn, white matter: posterior (dorsal) columns, lateral columns, anterior (ventral) columns, and central canal, providing a detailed look at its structural organization. Understanding these components enhances comprehension of neural pathways and reflex arcs.

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.

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.

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.
