METACARPAL
In human anatomy, the metacarpal bones or metacarpus form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist, which forms the connection to the forearm. The metacarpal bones are analogous to the metatarsal bones in the foot.
CARPAL BONE
The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. There are eight carpal bones, which divide into two rows: a proximal row and a distal row.
METATARSAL BONE
The metatarsal bones are the bones of the forefoot that connect the distal aspects of the cuneiform (medial, intermediate and lateral) bones and cuboid bone to the base of the five phalanges of the foot. There are five metatarsal bones, numbered one to five from the hallux (great toe) to the small toe.
RIGHT FIRST RIB
The first rib is the most superior of the twelve ribs. It is an atypical rib and is an important anatomical landmark. It is one of the borders of the superior thoracic aperture. The ribs form the main structure of the thoracic cage that protects the thoracic organs.
