An understanding of the nervous system begins with an understanding of its basic morphological and functional unit, the neuron. Neurons are nerve cells that form the conducting system that carries information throughout the central and peripheral nervous systems The nervous system is divided structurally into the central nervous system (CNS) and the peripheral nervous system (PNS), although remember that these are really two components of one, integrated system. The CNS consists of the brain and the spinal cord, while the PNS is composed of nerves and groups of nerve cells (neurons), called ganglia Nervous system Practical class-Histology Lecturer: Ghada Abdul Rahman Sultan. Nervous system •Receive stimuli from both internal and external environments which are then analyses and integrated to produce appropriate coordinated responses in various effector organs.

ISSN:2448-0959. ABSTRACT. The nervous system is basically bruised by one of the four basic types of tissues of the body, the nervous tissue, being distributed throughout the body Central Nervous System. The central nervous system consists of the brain and spinal cord. All other nervous system elements are considered to be in the peripheral nervous system. An astrocyte is a supporting cell seen in the central nervous system. Basket cells are a type of neuron seen in the cerebellum by S. Ramon y Cajal, translated from French by Neely Swanson and Larry W. Swanson, Oxford, Oxford University Press, 1995 A major neuroanatomic debate during the last quarter of the 19th century centered on the nature of connections between nerve cells. The debate began when Camillo Golgi refined the silver stain and used it to demonstrate, for the first time, the complexity of constituents and. History of Neuroscience A synthesis of the work of Santiago Ramon y Cajal, founder of modern neuroscience and one of the leading biologists of the 19th century The first to see how neurons interact in the brain, laying the foundation for what came to be known as the neuron doctrin

NERVOUS SYSTEM 25/01/2017 2 •The most complex system in the human body •Formed by network more than 100 million neuron •Each neuron has a thousand interconnection a very complex system for communicatio The study of nervous system histology could easily comprise the entire subject matter of this course and a couple more. Thus, we will just be considering only a broad overview of the subject. Nervous tissue is the subject of intense interest, not only because of its complexity, but because it is the seat of thought, emotion, and behavior The nervous system is the most complex organized system of the body, however, which is why it is more interesting. After a thorough analysis of the histology and anatomy of the nervous system, further study of the diseases that affect it will be much easier for you . 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; Nervous system is divided functionally into two.

The two major divisions of the nervous system are the central nervous system (CNS), consisting of the brain and spinal cord, and the peripheral nervous system (PNS) consisting of the peripheral nerves, nerve receptor endings, and ganglia distributed throughout the body.. 2 ) The central nervous system is connected with the peripheral nervous system by all the following types of nerve fibers, except :- a- postganglionic autonomic fibers b- preganglionic autonomic fibers c- somatic motor fibers d- autonomic sensory fibers 3 ) The sensory system is involved in all the following, except :- a- initiation of reflex.
Histology and Histopathology of the Nervous System by Haymaker, Webb and a great selection of related books, art and collectibles available now at AbeBooks.co.uk . The peripheral nervous system consists of two types of structures. The first are called nerves. Let me just underline this nerve right here The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary.
The peripheral nervous system or PNS consists of all the nerves and ganglia outside of the central nervous system. The central nervous system consists of the cerebellum, cerebrum, brainstem, and spinal cord.. The peripheral nerves consist of at least one bundle of nerve fibers called a fascicle, which has a surrounding layer of connective tissue called the perineurium The nervous system controls the activities of all body organs and tissues, receiving input from sensory organs and responding via effector organs. With around 100 billion interconnected neurons, the brain is an extremely complex, and still poorly understood, organ. However we do understand, to some degree, how age affects it, as well as the. It is the structural and functional unit of the nervous tissue that is specialized in excitability and conductivity. Each neuron is composed of cell body (perikaryon) and cell processes. They are located in the gray matter of the central nervous system, eye (rods and cones), ears (organ of Corti), olfactory mucosa, and ganglia Histology of Nervous.

The nervous system is made up of a collection of nerves and specialized cells known as neurons tasked with transmitting signals from different parts of the body. The body has billions of nerve cells that have over a hundred billion neurons The tiny central canal recalls the origin of the nervous system as an infolding which closes off to form the neural tube. Locate the central canal in the middle of your section and examine the lining layer of ependyma l cells The nervous system is the master controlling and communicating system of the body. Every thought, action, and emotion reflects its activity. Its signaling device, or means of communicating with body cells, is electrical impulses, which are rapid and specific and cause almost immediate responses Study Histology of Nervous Tissue flashcards taken from chapter 15 of the book Human Anatomy and Physiology Laboratory Manual, Fetal Pig Version
