Musically, it would be connected to the "arm bone" (or "wrist bone", depending on the version).
Anatomically, there's no such thing as a "hand bone" (there's no "arm bone" or "wrist bone" either), at least not in the sense that there's a single bone known by that name. The hand (and arm, and wrist) contain multiple bones.The bones in the hand are called phalanges (the bones in the fingers and thumb) and metacarpals (the bones buried in the palm). If your version of "Dem Bones" has the hand bone connected to the arm bone without an intermediate "wrist bone", then the "hand bone" would include the carpals (in the wrist) as well (or maybe those are lumped into "arm bone"; the song is so imprecise it's hard to tell).
The carpals all have individual names. The metacarpals are numbered.based on what finger they're in (the thumb is 1, and the numbering goes up moving toward the pinky). The phalanges are numbered as well (the same number as the metacarpal they connect with), with the one that actually has a joint with the metacarpal being the "proximal" phalange, and the one furthest away being the "distal" phalange. In the fingers (but not the thumb) there's a phalange between those two, known (sensibly) as the "intermediate" phalange. So the "fourth proximal phalange" of the left hand would be the one normally surrounded by a wedding ring.
Technically that doesn't answer your question, so here's the literal answer. This should have been obvious, but the "hand bone(s)" are located in the hand.
The lunate bone is a carpal located in the hand.
The longest bone in the human hand is the metacarpal bone, located between the wrist and the fingers.
There are 206 bones in in an adult humans body. The Capitate bone is located in the human hand specifically near the base of the hand and just before the wrist,
The hamate bone is the carpal bone that has a hook-like process called the hamulus. It is located on the medial side of the hand.
The scaphoid, or navicular bone is located within the anatomic snuffbox. Pain in this location after a fall on the hand or wrist may indicate a fracture of the scaphoid.
it is the bigger bone in the lower arm....it is the bone on the thumb side of the lower arm
The name of mid hand bone is metacarpal. These are five in number in each hand.
The capitate bone is classified as a carpal bone, specifically one of the eight bones in the wrist known as the carpal bones. It is a rounded bone located in the center of the wrist, and plays a key role in supporting the structure and movement of the hand.
a fused bone is located in you skull and in your sacrum and coccyx( tail bone)
it is located mainly in the proximal and distal epiphysis (the ends of a bone.)
The scaphoid bone is found in the human wrist. It is one of the carpal bones and is found between the hand and forearm on the thumb side of the wrist.
The longest bone is the femur, and it is located in the thighs.
