tarsal骨和腕骨之间的区别

Thekey differencebetween tarsal and carpal bones is thattarsal bones are a cluster of sevenbonespresent in the foot while carpal bones are the eight small bones that connect our hand into the forearm.

Wrist and ankle are important parts of the humanskeleton. Wrist or carpus contains eight carpal bones. These carpal bones connect hand and forearm. Our foot consists of 26 bones. Ankle or tarsus contains seven articulating tarsal bones. They are situated between the lower end of tibia and fibula of the lower leg and the metatarsus.

What are Tarsal Bones?

Tarsus or ankle joint consists of seven tarsal bones. They are the talus, calcaneus, cuboid, navicular and three cuneiforms. Talus and calcaneus are in the hindfoot while cuboid and cuneiforms are in the midfoot. The navicular bone is an intermediate bone located between the two above groups. Talus is the most superior bone resting on the top of the calcaneus.

Calcaneus, also known as heel bone, is the largest and strongest bone in humans. It acts as the weight-bearing bone within the heel of the foot. Navicular bone resembles a small boat while cuneiform bones are wedge-shaped. Tarsal bones are situated between the lower end of胫骨和腓骨下腿和metatarsus。

什么是腕骨？

Carpal bones are the eight small angular bones that make the human wrist. They are arranged in two rows of four bones: the proximal row and the distal row. Scaphoid, lunate, triangular, and pisiform bones form a row towards the forearm. The other four bones – trapezium, trapezoid, capitate, and hamate – form a row towards the fingers. Moreover, each carpal bone has six phases as superior, inferior, medial, lateral, anterior, and posterior surfaces.

尽管哼ans have eight carpal bones, the number varies among different vertebrates. Furthermore, the structure of the carpus varies widely between different groups of tetrapods.

What are the Similarities Between Tarsal and Carpal Bones?

• 骨骨和腕骨是脊椎动物骨骼的重要部分。
• 两者都是几个小骨头的簇。
• 此外，它们被组织成排。

What is the Difference Between Tarsal and Carpal Bones?

Tarsal bones are the group of seven bones forming the ankle of the foot. On the other hand, carpal bones are the group of eight bones forming the joint between the forearm and the hand. Therefore, this is the key difference between tarsal and carpal bones. In fact, there are seven tarsal bones while there are eight carpal bones. Besides, talus, calcaneus, cuboid, navicular and three cuneiforms are the seven tarsal bones. Meanwhile, scaphoid, lunate, triangular, pisiform, trapezium, trapezoid, capitate, and hamate are the eight carpal bones.

Moreover, another difference between tarsal and carpal bones is their organization. Tarsal bones are organized into three rows as proximal, intermediate and distal, while carpal bones are organized into two rows as proximal and distal.

概括– Tarsal vs Carpal Bones

在脚部发现了骨骨头，而手中则发现腕骨。Tarsal骨头是七骨组成的一组，形成了脚的脚踝。它们在脚上被组织成三排。腕骨是八骨组成的簇，形成手腕。它们被组织成两排。因此，这是tarsal骨和腕骨之间差异的摘要。
