The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Veins of Upper Limbs

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial. The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
FAQs
The endoscope combines a camera and light to produce real-time views while it advances through the upper gastrointestinal tract. This lets clinicians inspect lining changes directly rather than relying only on symptoms. Because the instrument can also collect tissue or other samples, a single examination can support both visual assessment and additional diagnostic evaluation.
Tissue sampling adds information that direct inspection alone may not provide. During the examination, clinicians can collect biopsies or other samples from areas that appear abnormal or require clarification. This makes the procedure useful not only for locating ulcers, inflammation, tumors, or structural abnormalities, but also for obtaining material that supports diagnostic decision-making.
Upper endoscopy can shift from observation to treatment when an abnormality requires immediate attention. Through the endoscope, clinicians may control bleeding, remove a foreign body, or dilate a narrowed area. These capabilities distinguish the procedure from an examination that only records images, because the same access route can support targeted intervention during the clinical evaluation.
Appropriate preparation and sedation affect how the examination is conducted. Preparation is completed before the scope is introduced, and sedation is usually used to support the procedure. The flexible instrument then passes through the mouth, allowing the clinician to examine the relevant organs in sequence and obtain samples or perform supported interventions when indicated.
Persistent pain, difficulty swallowing, bleeding, and anemia are important reasons clinicians may select this examination. The procedure can connect these symptoms with visible abnormalities such as inflammation, ulcers, tumors, or structural changes. In this way, it helps investigate symptom-driven concerns and signs suggesting upper gastrointestinal disease, including cases in which bleeding or anemia prompts evaluation.
Findings may reveal ulcers, inflammation, tumors, or structural abnormalities affecting the examined lining. Clinicians can also document bleeding or narrowed areas and decide whether tissue sampling or an intervention is appropriate. The resulting information supports a diagnosis and, when treatment is performed during the same session, records both the observed problem and the action taken to address it.
