The fingers (Digits) of the hand are movable in 4 directions, Flexion (bending), Extension (straightening), Abduction (moving sideways away from the body) and Adduction (moving sideways towards the body). This is contrary to what most non-anatomists beleive, as they think the joints are all hinge joints. That is infact untrue, the joints between the tip and the middle of the finger and between the middle and the base of the finger (the Interphalangeal joints) are indeed purely Hinge joints which means they can only flex and extend. However the joint bweteen the base of the finger and the hand (the Metacarpophalangeal joint) is something called a condyloid joint, more like the ball and socket type in the shoulder than the hinge type in the other finger joints. It is at these joints that abduction and aduction take place. There are many muscle controlling these different types of movememnt mostly located in the forarem not the hand in fact there are no muscles on the Dorsum (back of the hand) at al. It should also be noted that the thumb and, to a lesser extent, the pinky have muscles that ack uniquely on them. The muscles are Named below: The flexors of the digits located in the forearm (Extrinsic): Flexor Carpi Ulnaris; Flexor Carpi Radialis; Palmaris Longus; Flexor Digitorum Superficialis; Flexor Digitorum Profunfus The flexors of the digits located within the hand (Intrinsic): Only ones that act on the pinky or thumb. The extensors of the digits located in the forearm: Extensor Carpi Ulanris; Extensor Carpi Radialis Longus; Extensor Carpi Radialis Brevis, Extensor Digitorum; Extensor Indicis (only on index finger). Extensors of the digits located within the hand; Lumbricles, located in the palm but have tendons that reach round to the back to extend the digits. Abductors of the digits; Dorsal Inerosseous Adductors of the digits; Palmer Interosseous

∙ 13y agothe Extensor Carpi Radialis Longus, Extensor Carpi Radialis Brevis, Extensor Digitorum Communis, Extensor Digitorum Lateralis, Extensor Carpi Ulnaris, Flexor Carpi Ulnaris, and the Flexor Carpi Radialis.
all these muscles are located in your wrist. If im not right about this question im going to fail my 11th grade anatomy cat dissection test tomorrow...

∙ 11y agomovement in your fingers is a very complex process, you have both intrinsic and extrinsic muscles attaching to their respective joints in the finger. The majority of movement comes from extrinsic muscles found in your forearm. These are flexors and extensors. They have long band shaped tendons inserting to to distal end of your finger tips.

What pair of muscles work as you move your hand?
Depends HOW you are moving your hand, but most likely wrist flexor and extensors
How many muscles to lift a finger?
There are no muscles in the human finger. The muscles that bend the finger are located in the palm and in the mid forearm, and are connected to the finger bones by tendons, which pull on and move the fingers.
What are the important muscles of the body?
All of the muscles are important. Without your forearm muscles you can't move your fingers, without the bicep or tricep muscles you cant bend your elbow. and it goes on for every muscle in the body.

Can you move your hand if your wrist is broken?
That depends what you mean. Can you move your hand around like when you knock a door? If that is what you mean, no. However, if you're talking about moving your fingers as in moving your hand, yes, you can.Yes you can. You can rotate your wrist and move you hand. But it does depend on the break but do be aware that if you do move it you can make it worse.....
Are there muscles in the finger?
Visually speaking, no you cannot. There are only tendons in the fingers, so it is impossible to have 'muscular' fingers per se. It is possible to have very strong fingers/grip, but this comes from forearm strength, not from finger strength.
How do you say nice fish in sign language?

Why can you move the bones in your fingers but not in your skull?
The bones in your fingers have joints, and muscles that allow them to be articulated. The bone of the skull is a one piece item, and has no points of articulation. The hand is made to move so you can grasp things, while your skull is there to protect your brain.
Why are the muscles that move the fingers in the forearm?
Because there is no space for it to fit.
