The image displays a recently inserted temporary dual-lumen hemodialysis catheter positioned in the left internal jugular vein of a patient. This type of central venous access device serves as a crucial but temporary vascular access option for patients requiring urgent or short-term hemodialysis treatment. The catheter features two color-coded lumens—red for arterial (blood withdrawal) and blue for venous (blood return)—that facilitate the extracorporeal blood circuit necessary for dialysis.

The process of neural tube formation is a critical step in embryonic development, laying the foundation for the central nervous system. This diagram illustrates the key stages—starting from the neural plate to the formation of the neural tube and neural crest—offering valuable insights for medical students and professionals studying developmental biology. Explore this comprehensive guide to understand the intricate process and its significance in human anatomy.

A Peripherally Inserted Central Catheter, commonly known as a PICC line, is an essential medical device that provides prolonged intravenous access for patients requiring long-term medication administration, nutritional support, or frequent blood sampling. This thin, flexible tube is inserted through a peripheral vein, typically in the upper arm, and advanced until the tip reaches a central vein near the heart. PICC lines have revolutionized patient care by reducing the need for repeated needle sticks and providing a reliable vascular access route for extended periods, ranging from weeks to months.
