shorter ring finger than index finger.
The little finger is the shortest. It usually ends at the point of the joint between the third and second phalange of the ring finger.
The thumb is different from the fingers. It only has two phalanges. The thumb metacarpal is shorter and thicker than other metacarpal bones. It is also positioned more sideways on the hand, away from the hand palm area.
The heads of the metacarpal bones are known as the knuckles. They are easily detectable when the hand is bent into a fist.
Muscles of the Hand
Now let us examine the muscles of the hand, which will be useful to know when it comes to the topic of how to draw hands.
The muscles of the hand can be divided into intrinsic and extrinsic muscles.
The intrinsic muscles are small and mostly located on the bones of the hand.
The extrinsic muscles originate on the bones of the upper and lower arm.
Intrinsic muscles are divided into three groups – the group that attaches to the thumb, the group that moves the little finger, and the group located between the two groups.
The thumb muscle group consists of four muscles. The purpose of these muscles are to abduct and adduct the thumb as well as to flex it.
The muscle group of the little finger consists of three muscles that contribute to its movement.
The group of intrinsic muscles that lies between the thumb and the little finger includes eight muscles – four muscles located closer to the back of the hand and four muscles on the palm side of the hand (though some experts distinguish only three muscles instead of four on the palmar side).
The four muscles on the backside of the hand help spread the fingers apart while the four muscles on the palm side of the hand bring them closer together and assist in the flexion and extension of the fingers.
You might be surprised, but there are no muscles on the phalanges of the fingers, only tendons. The fleshy parts of fingers are skin, fat tissues, nerves, and the like.
The long tendons of the extensor muscles (of the lower arm) insert into the phalanges of the fingers…
