Explore the intricate anatomy of the human right hand through a deep dissection, revealing the complex interplay of bones, muscles, and ligaments from an anterior (palmar) view. This comprehensive guide highlights key structures, including the carpal bones, metacarpals, phalanges, and the critical carpal tunnel, essential for understanding hand function and common medical conditions. Gain valuable insights into the sophisticated biomechanics that enable the hand's remarkable dexterity and strength.
The right hand deep dissection from a posterior (dorsal) view provides an in-depth look at the anatomical structures on the back of the hand, highlighting the bones, muscles, and ligaments that contribute to its functionality. This medical image is a vital resource for medical students, anatomists, and healthcare professionals aiming to understand the intricate relationships between the hand's dorsal components. From the dorsal interosseous muscles to the interphalangeal ligaments, this guide offers a comprehensive exploration of the labeled anatomical features and their roles in hand movement and stability.
The right hand deep dissection from an anterior (palmar) view offers a detailed look into the intricate anatomy of the hand and wrist, showcasing the bones, ligaments, and muscles that enable its functionality. This medical image is an essential resource for medical students, anatomists, and healthcare professionals seeking to understand the complex structures of the hand. From the carpal tunnel to the deep transverse metacarpal ligaments, this guide provides a comprehensive exploration of the labeled anatomical features and their roles in hand movement and stability.
Vascular bypass grafting is a critical surgical intervention designed to redirect blood flow around a section of a blocked or partially blocked artery in the leg. This procedure acts as a biological detour, ensuring that oxygen-rich blood can bypass an obstruction caused by atherosclerosis to reach the lower leg and foot. By restoring proper circulation, this surgery plays a vital role in limb preservation and symptom relief for patients suffering from advanced stages of arterial disease.
The Ankle-Brachial Index (ABI) is a non-invasive diagnostic test used to assess vascular health by comparing blood pressure in the arms and legs. This procedure is the gold standard for detecting peripheral artery disease (PAD), a condition causing reduced blood flow to the limbs due to narrowed arteries. By utilizing a Doppler ultrasound device and standard pressure cuffs, clinicians can calculate a ratio that indicates the severity of arterial blockage, allowing for early intervention and management of cardiovascular risks.
Mechanical thrombectomy is a revolutionary endovascular procedure used to physically remove blood clots from large blood vessels, most commonly to treat acute ischemic stroke. This minimally invasive technique involves threading specialized devices through the vascular system to entrap and extract the obstruction, restoring critical blood flow to the brain. The illustration provided demonstrates the step-by-step mechanism of a stent retriever, a specific tool designed to integrate with the thrombus for safe removal.
The arterial switch operation is a complex, life-saving open-heart surgery performed primarily on newborns to correct a critical congenital heart defect known as Transposition of the Great Arteries (TGA). In this condition, the two main arteries leaving the heart are reversed, preventing oxygenated blood from circulating to the body. This article analyzes the anatomical transformation achieved through this procedure, detailing the physiological correction from a parallel circulation to a normal series circulation.
