- [PET Scan vs CT Scan: What's the Difference and Which One Do You Need?](https://humanbodypartsanatomy.com/pet-scan-vs-ct-scan/): Medical imaging is an important part of modern healthcare, especially when diagnosing, staging, and monitoring cancer. Two of the most commonly used imaging tests are PET (Positron Emission Tomography) scans and CT (Computed Tomography) scans. Although these tests are often performed together, they serve different purposes. A CT scan creates detailed images of the body’s internal structures, while a PET scan shows how tissues and organs are functioning by detecting changes in metabolic activity. Together, they provide doctors with a more complete understanding of a patient’s health. Why It’s Important to Know the Difference Understanding the difference between a PET scan ... Read more

- [Finger Anatomy: Parts of Finger, Bones, Joints, Muscles, Tendons & Diagram](https://humanbodypartsanatomy.com/finger-anatomy/): Overview of Finger Anatomy Fingers are unique parts of the hand found in humans and many other animals. Over millions of years, they have developed to handle both delicate and strong tasks with skill.[1] Each finger has three bones, called phalanges, which are joined together and surrounded by muscles, tendons, and ligaments that help them move precisely.[2][3] Tendons link the muscles to the bones, allowing the fingers to bend, grip, and release objects easily.[4] Ligaments stabilize the joints and keep them in position,[5] while nerves provide sensory feedback like pressure, temperature, and texture.[6] Additionally, blood vessels supply essential nutrients and oxygen ...

[2] They are composed of keratin — a tough, flexible protein that also constitutes hair and the outer skin layer, which enables nails to grow continuously and withstand daily mechanical stress. [1] Nails protect sensitive fingertip tissues, enhance grip and precision, and contribute to tactile sensation. [1] Every nail is unique in shape, texture, and growth rate, reflecting individual genetic and physiological differences. [2]The nail anatomy is both complex and well-organised. Each nail consists of ... Read more
