Veins keep moving in wrist?
Hi The veins in my wrist / under arm are bothering me lately... Usually when i write when my tendon moves the veins move over the tendon and pop over .. it doesnt hurt but it is a sort of tickling feeling and it is pretty gross lol .. it happens when im lifting weights too but only in my dominant arm (Left).. How do i stop my veins from popping over the tendon? lol its a weird question but thanks in advance!
How does a human arm move?
Your brain sends motor information from the cortex to the muscle fibres that are been innervated by in the arm. Once that information reaches the neuromuscular junction, depolarization occurs. Then the interaction between actin and myosin myofilaments causes your muscle fibres to contract or relax depending on whether you want to flex you arms or extend them. If you wanted to flex them, then the muscle fibres contract, different muscles at different regions of the arm will flex different joints. Basically a tendon connects the muscle to the bone, so when those muscles contract, the tendons will pull on the bones as well and causes your bone joints to flex and move.
How do muscles work i.e to make the arms move??
For you to better understand the mechanism of muscular physiology, you must expose yourself with its anatomy. Bottom line: Skeletal Muscles are attached to bones by connective tissues called tendons Relevance: When the muscle contracts, the bones are moved. Eventually a certain action is performed. The molecular basis of muscle contraction is quite complicated. I'll share to you anyway a simple one. Every muscle cells have a reservoir of Calcium ions called sarcoplasmic reticulum. Calcium ions are relevant because when released it could uncover myosin binding site on the actin filament and eventually would allow contraction. What stimulates the sarcoplasmic reticulum to release its Ca2+ store? Its the depolarization event due to signals from the nervous system.
I have issues with moving my arms and legs at the same time? Can I anyone help me?
Thanks for asking. I would recommend that you spend time exploring developmental movements such as creeping & crawling. We originally develop our coordination on the ground, and getting back down there can help quite a bit with "relearning" lost motor patterns.
When I woke up today bottom of my forearm hurt only when I moved my fingers around...?
ur muscles on your fingers got used to the shape of your spray paint and ur forearm is the one suffering because the pain is radiating which means its moving.. the tendon on ur fingers is connected to ur forearm muscle
Which muscles move each finger and thumb?
It is going to be a long list of muscles since there are a lot of actions in the fingers. Before mentioning the muscles, we shall start with the terminology of muscle actions in the case of fingers.Digit - finger. Across the thumb to little finger, the fingers are named as the 1st digit to 5th digit.Flexion (F) - curling a digit towards the palmExtension (E) - curling a digit in the opposite direction of FAbduction (Ab) - spreading a digit away from the 3rd digit on the plane of palm (for the 3rd digit, Ab means to move it left or right)Adduction (Ad) - moving a digit towards the 3rd digit on the plane of palm, opposite of Ab (no Ad for the 3rd digit)Opposition (Op) - using the thumb to touch other digits’ padsCircumduction - combination of F, E, Ab and AdExtrinsic muscles whose muscle bellies are in our forearms and intrinsic muscles in our hands work in tandem to control our hand movements. I will write the intrinsic muscles in italic (‘intrinsic’ for ‘italic’)The following introduces you what muscle(s) contribute(s) to each muscle action of each digit. To make it more simple, only the muscles that contribute the most to an action are included, but in reality, some other muscles also assist the prime movers in performing an action.ThumbF: flexor pollicis longus, flexor pollicis brevis (pollicis means pollex, the thumb; longus means long; brevis means short)E: extensor pollicis longus, extensor pollicis brevisAb: abductor pollicis longus, abductor pollicis brevisAd: adductor pollicisOp: opponens pollicisIndex fingerF: flexor digitorum superficialis, flexor digitorum profundusE: extensor digitorum, extensor indicisAb: 1st dorsal interosseiAd: 1st palmar interosseiF at the knuckle and E at distal finger joints: 1st lumbricalMiddle fingerF: same as index fingerE: extensor digitorumAb towards 2nd digit: 2nd dorsal interosseiAb towards 4th digit: 3rd dorsal interosseiF at the knuckle and E at distal finger joints: 2nd lumbricalRing fingerF and E: same as 3rd digitAb: 4th dorsal interosseiAd: 2nd palmar interosseiF at the knuckle and E at distal finger joints: 3rd lumbricalLittle fingerF: flexor digitorun superficialis, flexor digitorum profundus, flexor digiti minimi brevis (digiti minimi means little finger, the minimal digit)E: extensor digitorum, extensor digiti minimiAb: abductor digiti minimiAd: 3rd palmar interosseiOp: opponens digiti minimiF at the knuckle and E at distal finger joints: 4th lumbrical
What's the best position to rest your arm in when having a tired wrist or carpal tunnel syndrome?
Generally speaking avoid high frequency up and down wrist motion or extremes of wrist motion. A splint can aid in this.As to seeking relief, especially at night when symptoms are severe, it's a very individual thing. Some people find relief with the hand pointed up, others with it down.Ignore answers like those of Malcom Kogut, filled with all sorts of misinformation. The most egregious information, repeated often are the scare tactics regarding surgery.It so happens that some operations are simpler, less risky and more predictably helpful than others. Carpal tunnel surgery is in that category. For the vast majority of people, it's a non event and is curative. A 15 minute outpatient procedure under local anesthesia with an itty bitty scar that in most people is not even visible after a month or two.If you can get relief without surgery, of course thats preferable, but if not then surgery is a no brainer.
