A bruise is a mark on the skin caused by injury, where blood vessels underneath the skin break and leak blood into the surrounding tissue. Typically, bruises appear as discolored patches ranging from blue and purple to yellow or green as they heal. They are often tender to the touch but usually fade away over time as the body reabsorbs the leaked blood and repairs the damaged tissue.

A blister is a small, fluid-filled bump on the skin. It forms when the outer layer of the skin becomes damaged, often due to friction, burns, or irritation. The fluid inside the blister helps protect the damaged skin and promote healing. Blisters can vary in size and may be painful or itchy. They usually heal on their own within a few days as the body reabsorbs the fluid and the skin underneath repairs itself. Avoiding further irritation and keeping the blister clean can help prevent infection and promote faster healing.

A sprain is an injury to a ligament, which is the tissue that connects bones to each other in joints. It typically happens when a joint is forced beyond its normal range of motion, causing the ligament to stretch or tear. Sprains commonly occur in the ankles, wrists, or knees and can result in pain, swelling, and difficulty moving the injured joint. Depending on the seriousness, sprains may require rest, ice, compression, and elevation or medical attention such as physical therapy to fully recover.

An arm refers to the upper limb of the human body, extending from the shoulder to the hand. It consists of bones, muscles, tendons, and ligaments that work together to provide mobility and dexterity.

It plays a significant role in daily activities, such as writing, eating, and performing various tasks. The arm is crucial for both functional tasks and expressive gestures, contributing to overall physical capabilities and communication. Understanding the anatomy and function of the arm is essential for maintaining strength, coordination, and flexibility in this important part of the body.

Food poisoning is an illness that happens when you eat food contaminated with harmful bacteria, viruses, parasites, or toxins. It can cause symptoms such as stomach cramps, nausea, vomiting, diarrhea, and fever. The symptoms can start soon after eating contaminated food or may take several hours or days to appear, depending on the type of germ involved. Most cases of food poisoning are mild and resolve on their own within a few days with rest and drinking plenty of fluids to stay hydrated. However, in severe cases, medical attention may be needed to prevent dehydration or complications.

A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart muscle is blocked for an extended period, causing damage or death to the heart tissue. This blockage is typically caused by a buildup of fatty substances in the coronary arteries, which can burst and form a blood clot. Symptoms of a heart attack include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain or discomfort in the arms, back, neck, or jaw. Immediate medical attention is crucial to restore blood flow and minimize heart damage. Treatment may involve medications, lifestyle changes, and procedures such as angioplasty or surgery to improve blood flow to the heart.
