Asthma

Posted on February 3, 2022 by admin

However, asthma is often the result of a strong response of the immune system to a substance in the lungs. To understand asthma, it helps to understand How the Lungs Work.

What does asthma do to the lungs? Asthma is a chronic (lifetime) disease. Asthma varies from person to person and can change over time. Many people with asthma can go for long periods of time without any symptoms, for example. There is no cure for asthma, but asthma can be controlled.

Get Help. Asthma is a chronic (life time) disease that makes your lungs very sensitive and hard to breathe. Asthma can’t be cured, but with proper treatment, people with asthma can lead normal, active lives. If you have asthma, your airways (breathing passages) are very sensitive.

Arm Muscles

Posted on February 3, 2022 by admin

In this article, we shall look at the anatomy of the muscles of the upper arm – their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm – biceps brachii, coracobrachialis and brachialis.
The muscles of the arm and hand are specifically designed to meet the body’s diverse needs of strength, speed, and precision while completing many complex daily tasks. Activities such as lifting weights or heavy boxes require brute strength from the muscles of the arm.
The arm muscles of the upper limb act on the elbow and shoulder joints to produce the various movements of the forearm. Five arm muscles play a role in these movements: biceps brachii, brachialis, coracobrachialis, triceps brachii and anconeus. The first three are primarily involved in forearm flexion, hence they are called flexors.

Ankle Sprains Diagram

Posted on February 3, 2022 by admin

Anatomy of an Ankle Sprain. An ankle sprain occurs when the strong ligaments that support the ankle stretch beyond their limits and tear. Ankle sprains are common injuries that occur among people of all ages. They range from mild to severe, depending upon how much damage there is to the ligaments.

Patients who have a high ankle ligament tear usually will have pain just above the level of the ankle, thus a “high” ankle sprain. They may also have tenderness over the deltoid ligament if they have a Maisonneuve injury, as noted above. It is important to touch the area to assess whether pain is just around the lateral ankle ligaments or higher.

High ankle sprain: The ligament joining the two bones of the lower leg (tibia and fibula), called the syndesmotic ligament, is injured. A high ankle sprain causes pain and swelling similar to a true ankle sprain, but can take longer to heal.

Ankle Sprain Causes

Posted on February 3, 2022 by admin

A twisting force to the lower leg or foot can cause a sprain. The lateral ligaments on the outside of the ankle are injured most frequently. Reproduced from the Body Almanac @ American Academy of Orthopaedic Surgeons, 2003. Your foot can twist unexpectedly during many different activities, such as:

Causes of a sprained ankle might include: A fall that causes your ankle to twist. Landing awkwardly on your foot after jumping or pivoting. Walking or exercising on an uneven surface. Another person stepping or landing on your foot during a sports activity.

Injury or trauma-related ankle pain causes 1 Sprains, strains, and fractures: These are the most commonly reported causes of ankle pain. Any of these can happen if… 2 Achilles tendon rupture: The Achilles tendon attaches the calf muscle to the heel bone, known as the calcaneus. If this… More …

Ankle Ligaments

Posted on February 3, 2022 by admin

Ligaments of the ankle. Lateral ankle ligaments. The lateral side of the ankle has three supporting ligaments: the anterior talofibular ligament (ATFL), the posterior talofibular ligament (PTFL) and the calcaneofibular ligament(CFL). The three ligaments are together called the Lateral Collateral Ligament Complex.
Keywords: Ankle anatomy, Lateral collateral ligament, Medial collateral ligament, Ankle impingement, Ankle sprain Introduction Despite the fact that the ankle ligaments are prone to injury during the fast majority of sports, literature focusing on the ankle ligaments is rare.
On the outer side of your foot, you have several ligaments. These include the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL). These help keep your ankle and foot steady when you walk. If you have had repeated ankle sprains or if you have certain foot deformities, your ligaments can start to get weak and loose.

Ankle Anatomy

Posted on February 3, 2022 by admin

There are a variety of anatomical structures that make up the anatomy of the foot and ankle (Figure 1) including bones, joints, ligaments, muscles, tendons, and nerves. These will be reviewed in the sections of this chapter.
The ankle joint is formed by the connection of three bones. The ankle bone is called the talus. The top of the talus fits inside a socket that is formed by the lower end of the tibia (shinbone) and the fibula (the small bone of the lower leg).
[edit on Wikidata] The ankle, or the talocrural region, is the region where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot.

Aids Virus

Posted on February 3, 2022 by admin

HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. … It is the virus that can lead to acquired immunodeficiency syndrome or AIDS if not treated.

AIDS is the late stage of HIV infection that occurs when the body’s immune system is badly damaged because of the virus. In the U.S., most people with HIV do not develop AIDS because taking HIV medicine every day as prescribed stops the progression of the disease.

Symptoms of HIV 1 You cannot rely on symptoms to tell whether you have HIV. 2 Early Stage of HIV. About 40% to 90% of people have flu-like symptoms within 2-4 weeks… 3 Clinical Latency Stage. After the early stage of HIV infection,… 4 Progression to AIDS. If you have HIV and you are not on ART,…

However, HIV will generally follow this pattern: Approximately 80 percent of people who contract HIV experience flu-like symptoms within two to four weeks. This flu-like illness is known as acute HIV infection. Acute HIV infection is the primary stage of HIV and lasts until the body has created antibodies against the virus.

Not everyone will have the same symptoms. It depends on the person and what stage of the disease they are in. Below are the three stages of HIV and some of the symptoms people may experience. Within 2 to 4 weeks after infection with HIV, about two-thirds of people will have a flu-like illness. This is the body’s natural response to HIV infection.

Nervous System

Posted on February 2, 2022 by admin

The nervous system or the neural is a complex network of nerve cells or neurons specialized to carry messages. The complexity of the nervous system increases as we move towards higher animals. In simple organisms, especially in the invertebrates, neural system is just a network of neurons.

It is the body’s communication system that controls much of what your body does. It allows you to do things like walk, speak, swallow, breathe and learn, and controls how your body reacts in an emergency. Your nervous system is made up of: your peripheral nervous system, which consists of nerves that connect your CNS to the rest of your body

Thus, the nervous coordination involves the participation of the sense organs, nerves, spinal cord, and brain. One of the most complex organ system to ever evolve, the human nervous system consists of two parts, namely: Central Nervous System (CNS) is often called the central processing unit of the body.

Muscles System

Posted on February 2, 2022 by admin

Last Updated: Jul 16, 2019 The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.

Related to the function of movement is the muscular system’s second function: the maintenance of posture and body position. Muscles often contract to hold the body still or in a particular position rather than to cause movement.
