Why are the muscles that move the fingers and wrist located in the forearm? This design allows the hand to maintain fine motor control and strength without the interference of bulky muscles. The forearm muscles can be divided into anterior flexors and posterior extensors, as well as __________.

Terms in this set (32)

• Wrist flexion agonist. Flexor digitorum.
• Wrist flexion antagonist. Extensor digitorum.
• Wrist extension agonist. Extensor digitorum.
• Wrist extension antagonist. Flexor digitorum.
• Elbow flexion agonist. Biceps brachii.
• Elbow flexion antagonist. Triceps brachii.
• Elbow extension agonist.
• Elbow extension antagonist.

The agonist muscles that contract concentrically to extend the dominant elbow joint are: triceps brachii; anconeus. The antagonist muscles that contract eccentrically to extend the dominant elbow joint are: biceps brachii; brachialis; brachioradialis.

Which muscles allow you to extend your wrist and flare your fingers? The muscles that allow you to extend your writs and flare your fingers are the Extensor Digitorum, Extensor Carpi Radialis Longus, Extensor Carpi Radialis Brevis, Extensor Carpi Ulnaris, and the Extensor Digiti minimi E.

Results: Normal values for wrist ROM are 73 degrees of flexion, 71 degrees of extension, 19 degrees of radial deviation, 33 degrees of ulnar deviation, 140 degrees of supination, and 60 degrees of pronation.

The tendons that control movement in your hands, wrists and fingers run through your forearm. There are 6 tendons that help move your wrist. The wrist tendons are: Flexor carpi radialis: This tendon is one of two tendons that bend the wrist.

A torn ligament in the wrist is sometimes mistaken as a sprain. You might feel pain in the wrist at the time of the injury, and pain while moving the wrist after the injury. Even with rest, the pain may not decrease significantly, and there may be swelling, bruising, or a feeling of popping or tearing in your wrist.

Symptoms of hand, elbow, and wrist tendon injuries include pain, swelling, a popping or snapping sound at the time of injury, and difficulty moving the affected area, among others.

Symptoms of a wrist sprain are:

• Pain.
• Swelling.
• Tenderness and warmth around the injury.
• Feeling a popping or tearing in the wrist.
• Bruising.
• Loss of motion.
• Weakness.

If you injure your wrist in a fall or accident, you may need to wrap it to help with the swelling and to speed up healing. A minor wrist sprain can often be treated with compression wrapping, but if you have severe pain in your wrist, seek medical attention. Make sure that you don’t wrap your wrist too tightly.

Your wrist hurts because you have stretched or torn ligaments, which connect the bones in your wrist. Wrist sprains usually take from 2 to 10 weeks to heal, but some take longer. Usually, the more pain you have, the more severe your wrist sprain is and the longer it will take to heal.

When the tendon in the wrist that connects the joint to the bone is damaged, it begins to rub over the bone or muscles in its way (instead of moving fluidly) and causes the “snapping” or “popping” sensation. The tendon moves in this irregular way because its foundation, the ligaments, have also become damaged or lax.

Common treatments include:

1. splints and compression to give the overworked tendon time to rest and heal.
2. stretching to improve flexibility.
3. hot and cold therapy to reduce swelling.
4. acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs)
5. corticosteroid injections to control inflammation.

“Once a tendon is injured, it almost never fully recovers. You’re likely more prone to injury forever.”

Tendons require weeks of additional rest to heal. You may need to make long-term changes in the types of activities you do or how you do them. Apply ice or cold packs as soon as you notice pain and tenderness in your muscles or near a joint. Apply ice 10 to 15 minutes at a time, as often as twice an hour, for 72 hours.

Healing can take up to 12 weeks. The injured tendon may need to be supported with a splint or cast to take tension off of the repaired tendon. Physical therapy or occupational therapy is usually necessary to return movement in a safe manner.

To provide tendon cells with the necessary amino acids to strengthen structural and force transfer proteins, you must consume the vitamin C-enriched hydrolyzed collagen 30 to 60 minutes before training—Supercharged Collagen is the only product designed specifically for hard-training climbers and other tendon-straining …

What is the most common type of load on a tendon? Tendons are easily deformed at low strain rates. As a result, tendons absorb more energy but are less effective in transmitting loads. At high strain rates, they become stiffer and less deformable but are more effective in moving large loads in vivo.

Rock climber’s top six exercises to up your grip strength

1. Exercise 1: Grip tools — easy.
2. Exercise 2: Climbing — easy to advanced.
3. Exercise 3: Barbell finger curls — easy to moderate.
4. Exercise 4: Pinch blocks — moderate.
5. Exercise 5: Deadlifts — moderate.
6. Exercise 6: Dead hangs — moderate.

A frequently asked question is whether or not hand grippers actually work. The short answer is yes, they definitely do. As the hand grippers work to improve the strength of individual fingers, it also increases your dexterity over time. – Increased hand strength.

Differences in grip and press strength show that the middle and index fingers are stronger than the ring and little fingers, whereas the little finger is the worst (Li, Latash, & Zatsiorsky, 1998; MacDermid et al., 2004; Talsania & Kozin, 1998;Quaine, Vigouroux, & Martin, 2003).
