The parts that make up your hand and wrist are layered upon each other to form a three-dimensional shape that gives them the ability to move and function. Your hand and wrist are made of: 1. Bones. 2. Muscles. 3. Nerves. 4. Tendons. 5. Ligaments. 6. Blood vessels(arteries and veins). 7. Lymphatic vessels.
Bones provide the main structural support in your hand and wrist. They give them their shape and are the anchors other pieces are connected to.
Muscles are soft tissue made of stretchy fiber. Intrinsic muscles inside your hand work with extrinsic muscles near the outside of your hand and in your forearm to give your hand its strength and dexterity.
Nerves control your muscles and help you feel and process sensations, including: 1. Touch. 2. Temperature. 3. Pain. 4. Pressure. Three main nerves give your hand and wrist sensation: 1. Radial nerve. 2. Median nerve. 3. Ulnar nerve. All three of these nerves are connected to many branches of smaller nerves that spread out into your hand and wrist.
Tendons link your muscles to your bones. They’re like strong, flexible ropes. Your hand and wrist have two groups of tendons: 1. Extensor tendons: Tendons that help you extend and straighten your fingers, hand and wrist. 2. Flexor tendons:Tendons that help you flex and curl your fingers, hand and wrist.
Ligaments are the other type of connective tissue in your hand. If tendons are like ropes, ligaments are more like thick rubber bands. Their main functions include: 1. Helping your joints move smoothly. 2. Protecting your joints from bending too far. 3. Keeping your joints in the proper alignment.
Your hand and wrist get blood from two arteries. The radial artery runs along your radius (closer to your thumb). The ulnar artery runs along your ulna (closer to your pinkie finger). These arteries communicate with each other in “arches” that form in your hand. There’s a superficial and deep arch in your hand. Vessels branch off the arches and sup...
Your lymphatic system is a network of tissue, vessels and organs that collect excess plasma from your bloodstream and redistribute it throughout your body. Tiny capillaries in your hand capture extra plasma from the blood vessels that supply your hand and wrist. They connect to bigger lymph nodes and vessels in your upper arm.
