Chapter 6 - Nervous Tissue. Nervous system is specialized for the rapid communication of information from one region of the body to another. Nervous system is divided anatomically into two major components: Central nervous system (CNS) – consists of the brain and spinal cord; Peripheral nervous system (PNS) – peripheral nerves and ganglia

Oct 11, 2024 · Fibrous connective tissue is composed of fibroblasts and extracellular matrix. Nerves are composed of many nerve fibers bound together with connective tissue sheaths.

Overall Objectives: to understand the histological components of nervous tissue; to recognize the morphological features of neurons; and to differentiate myelinated from non-myelinated axons

Jan 11, 2024 · Nervous tissue constitutes the primary building block of the nervous system. Comprising of neurons and glial cells, nervous tissue is designed for the rapid transmission of electrical impulses.

Histology by anatomical structure. This section deals with specific anatomical structures. Subependyma. Features: Ependyma (simple ciliated cuboidal epithelium). Subependymal plate - connective tissue with blood vessels. Caudate. Features: Neurons with adjacent ependymal lining. The caudate forms lateral wall of lateral ventricle. Notes:

Nervous Tissue • Controls and integrates all body activities within limits that maintain life • Three basic functions 1. sensing changes with sensory receptors 2. interpreting and remembering those changes 3. reacting to those changes with effectors (motor function) 2

Discuss the differences seen in nervous tissue stained with hematoxylin and eosin (H & E) and heavy metal (silver, gold) stains. Understand the organization of the Central Nervous System (CNS) and Peripheral Nervous System (PNS) as observed in the …

Glial cells (or neuroglia) provide support and protection to neurons. Four types of cells are found in the central nervous system: Astrocytes - provide physical and metabolic support; Oligodendrocytes - form myelin sheaths around multiple axons; Microglia - phagocytic cells

Dec 7, 2012 · The document summarizes the histology of neurons and the nervous system. It describes the key parts of neurons including the cell body, axon, and dendrites. It then discusses the different types of neuroglial cells that provide support to neurons in the central and peripheral nervous systems.
