Difference between Tarsal and Carpal Bones

Tarsal Bones

The tarsal bones are a group of bones that are found in each foot in higher complex organisms. In humans, the group consists of seven bones, namely cuboid, medial cuneiform, intermediate cuneiform, lateral cuneiform, navicular, talus and calcaneus. The seven bones are arranged in two rows as midfoot and hindfoot.

The toes have a different set of bones called metatarsals. The calcaneus bone is the largest bone in the group, and is located in the heel of the foot for weight bearing. The number and structure of bones is different in different vertebrates.

Carpal Bones

The carpal bones are a group of eight small bones that make up the wrist in higher vertebrates. It helps in connecting the hand to the forearm. The bones facilitate easy movement and flexibility in the arm.

The eight bones are scaphoid, trapezium, trapezoid, lunate, capitate, pisiform, triquetrum and hamate. These eight bones are arranged in three columns.

The bones are organised in two rows or three columns.

Importance

All the bones are important, but the calcaneus bone is the weight bearing bone present in the heel of the foot.

The bones in the wrist facilitate easy movement and provide flexibility to the arm.

Frequently Asked Questions on Difference between Tarsal and Carpal Bones

Why are there more carpal bones than tarsal?

The carpal bones are more in number so that they can provide mobility and flexibility to the arm.

What are carpal and tarsal joints?

The joints between the carpal and tarsal bones are the gliding joints that allow easy movement around the bones.
