The metacarpal bones are five in numbers and anatomically placed in the hand (in palm). Hence it makes a total of 10 metacarpal bones in two hands.
The metacarpal bones can also be placed in the category of long bones of upper extremities after humerous, radius and ulna.
Common characteristics are:
1. The base (Carpal extremity)
2. The body (The Shaft)
3. The head (distal extremity)
The Base or Carpal extremity articulates with the carpal bones and with the adjoining metacarpal bones.
The body is the shaft of the metacarpal bone. (medial area)
The head or the Distal extremity articulates with the proximal end of phalanx.
So far, it is clear that metacarpal bones are attached with proximal phalanges one side and with carpal bones on the other side, hence it can be concluded that metacarpal bones make the palm.
Now I think that the reader might have got his desired answer.

The fourth metacarpal bone articulates with the fourth proximal phalanx in the hand.
The third metacarpal bone of a horse is called the "cannon bone." It is located between the knee and the fetlock joint and is essential for weight-bearing and locomotion.
The longest bone in the human hand is the metacarpal bone, located between the wrist and the fingers.
Tarsals and carpals are short bones. Metacarpals, metatarsals and phalanges are long bones.
Each metacarpal bone consists of a base, a shaft, and a head. The base attaches to the carpal bones in the wrist, the shaft is the long middle portion of the bone, and the head connects to the phalanges in the fingers.
The capitate bone.
The fourth metacarpal bone articulates with the fourth proximal phalanx in the hand.
The third metacarpal bone of a horse is called the cannon bone or shin bone. The canon bone is the major support bone of body weight.
Metacarpal bones
A common fracture of the fifth metacarpal bone of the hand is often referred to as the "Boxer's Fracture." The fifth metacarpal is the bone in the hand that attaches to the pinky finger.
An osteotomy on the fingers metacarpal is a surgical procedure where the bone in the metacarpal of a finger is cut and reshaped to correct deformities or improve function. It is commonly done to correct conditions like arthritis or fractures that affect the metacarpal bone. The procedure aims to realign the bone and restore proper function and alignment in the finger.

The metacarpal bones in the palm of the hand carry and support the hand. There are five metacarpal bones in each hand that connect the fingers to the wrist.
The proximal phalanx of the thumb is immediately distal to the first metacarpal. In other words, the bone of the lower thumb connects to the first metcarpal.
The longest bone in the human hand is the metacarpal bone, located between the wrist and the fingers.
