** This encyclopedia entry is about **Rheumatoid Arthritis (RA)**, a chronic autoimmune disorder that causes inflammation, pain, and stiffness in the joints. **CONTENT:** ### Overview Rheumatoid Arthritis (RA) is a complex and multifaceted condition that affects millions of people worldwide. It is a chronic autoimmune disorder that causes the immune system to attack the lining of the joints, leading to inflammation, pain, and stiffness. RA can affect any joint in the body, but it most commonly affects the hands, feet, wrists, elbows, knees, ankles, and shoulders. The symptoms of RA can vary from person to person, but they often include joint pain and stiffness, swelling, redness, and warmth around the affected joints. In severe cases, RA can lead to joint deformity, loss of function, and even disability. RA is a systemic disease, meaning it can affect other parts of the body beyond the joints. It can also cause fatigue, fever, and loss of appetite. In some cases, RA can lead to complications such as osteoporosis, eye problems, and cardiovascular disease. Despite its challenges, RA is a treatable condition, and with proper management, people with RA can lead active and fulfilling lives. ### History/Background The exact cause of RA is still not fully understood, but research suggests that it is a complex interplay of genetic, environmental, and hormonal factors. The first recorded description of RA dates back to 1800 BCE in the Ebers Papyrus, an ancient Egyptian medical text. However, it was not until the 19th century that RA was recognized as a distinct medical condition. In the early 20th century, the discovery of the presence of rheumatoid factor (RF) in the blood of people with RA led to a better understanding of the disease. Today, RA is recognized as a chronic autoimmune disorder that requires long-term management and treatment. ### Key Information **Key Facts:** * RA affects approximately 1% of the global population. * Women are three times more likely to develop RA than men. * The average age of diagnosis is between 30 and 60 years old. * RA can affect any joint in the body, but it most commonly affects the hands, feet, wrists, elbows, knees, ankles, and shoulders. * The symptoms of RA can vary from person to person, but they often include joint pain and stiffness, swelling, redness, and warmth around the affected joints. **Treatment Options:** * Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), biologics, and corticosteroids. * Lifestyle Changes: Regular exercise, healthy diet, stress management, and adequate sleep. * Alternative Therapies: Acupuncture, massage, and physical therapy. ### Significance RA is a significant condition that affects not only the individual but also their family and loved ones. It can lead to loss of productivity, decreased quality of life, and increased healthcare costs. However, with proper management and treatment, people with RA can lead active and fulfilling lives. RA research has also led to a greater understanding of the immune system and the development of new treatments for other autoimmune disorders. **INFOBOX:** - Name: Rheumatoid Arthritis (RA) - Type: Chronic autoimmune disorder - Date: First recorded description in 1800 BCE - Location: Affects people worldwide - Known For: Chronic joint inflammation and pain **TAGS:** Rheumatoid Arthritis, Autoimmune Disorder, Chronic Disease, Joint Inflammation, Pain Management, Disease-Modifying Antirheumatic Drugs, Biologics, Corticosteroids, Lifestyle Changes.

** The **Nervous System** is a complex network of nerve cells, nerve fibers, and support cells that transmit and process information throughout the body, controlling various functions such as movement, sensation, perception, and cognition. **CONTENT:** ### Overview The **Nervous System** is a vital system in the human body, responsible for controlling and coordinating various bodily functions. It is a complex network of specialized cells called **neurons**, which transmit and process information through electrical and chemical signals. The nervous system is divided into two main parts: the **Central Nervous System (CNS)**, which includes the **brain** and **spinal cord**, and the **Peripheral Nervous System (PNS)**, which includes nerves that connect the CNS to the rest of the body. The nervous system plays a crucial role in controlling various functions such as movement, sensation, perception, and cognition. It enables us to think, learn, and remember, and it also regulates our emotions, hunger, thirst, and other basic bodily functions. The nervous system is highly adaptable and can reorganize itself in response to injury or disease, a process known as **neuroplasticity**. ### History/Background The study of the nervous system dates back to ancient civilizations, with the Greek physician **Galen** (129-216 AD) being one of the first to describe the nervous system in detail. However, it was not until the 17th century that the English physician **Thomas Willis** (1621-1675) published a comprehensive description of the nervous system, including the discovery of the **cerebral cortex**. The development of the **microscope** in the 17th century allowed scientists to study the nervous system in greater detail, leading to a greater understanding of the structure and function of neurons. ### Key Information The nervous system is composed of several key components, including: * **Neurons**: specialized cells that transmit and process information * **Dendrites**: branching extensions of neurons that receive signals from other neurons * **Axons**: long, thin extensions of neurons that transmit signals to other neurons or to muscles or glands * **Synapses**: small gaps between neurons where chemical signals are transmitted * **Myelin**: a fatty substance that surrounds and insulates axons, allowing for faster transmission of signals The nervous system is also divided into several different types, including: * **Somatic nervous system**: controls voluntary movements, such as walking and talking * **Autonomic nervous system**: controls involuntary functions, such as heart rate and digestion * **Sensory nervous system**: transmits sensory information from the environment to the brain * **Motor nervous system**: transmits signals from the brain to muscles and glands ### Significance The nervous system is a vital system in the human body, and its proper functioning is essential for overall health and well-being. Damage to the nervous system can result in a range of disorders, including **stroke**, **spinal cord injury**, and **neurodegenerative diseases** such as **Alzheimer's disease** and **Parkinson's disease**. Understanding the nervous system is also crucial for the development of new treatments and therapies for a range of conditions, including **pain management**, **neuroregeneration**, and **neuroprotection**. **INFOBOX:** - Name: Nervous System - Type: Biological System - Date: Ancient civilizations (Galen, 129-216 AD) - Location: Throughout the body - Known For: Controlling and coordinating various bodily functions **TAGS:** Nervous System, Brain, Spinal Cord, Neurons, Neuroplasticity, Cerebral Cortex, Microscope, Synapses, Myelin, Somatic Nervous System, Autonomic Nervous System, Sensory Nervous System, Motor Nervous System, Stroke, Spinal Cord Injury, Neurodegenerative Diseases, Alzheimer's Disease, Parkinson's Disease, Pain Management, Neuroregeneration, Neuroprotection.
