Please explain why the tarsal region is distal to the crural

Please explain why the tarsal region is distal to the crural region and also why the thumb is proximal to the ring finger.Thank you

Solution

Ans.) In human body, the lower limb body region is known as tarsal region or ankle region. It illustrates the region between the leg and foot including the tarsal bones (tarsus) and ankle joint (talocrural joint). In our body feet at the distal end of the ankle region (tarsal region), there is a talus bone (ankle bone), connected superiorly to both the tibia (shinbone) and fibula (calf bone), of the lower leg which eventually forms the ankle joint (talocrural joint) and inferiorly, at the subtalar joint it is connected to the calcaneus (heel bone) of the foot.

The crural region (leg) extends from the knee to the ankle that contains the medial and lateral fibula tarsal region ankle. The union of the crural region with the foot tarsol bones is considered as a part of the foot pedal region foot. Hence, it provides balance to the body and necessary support to stand properly.

The first digit of our hand is the thumb, followed by index finger, middle finger, ring finger, and little finger. There are fourteen digital bones in our hands called phalanges or phalanx bones: two in the thumb (the thumb has no middle phalanx) and three in fingers. These are the distal phalanx, conveying the nail, center phalanx and proximal phalanx. Every finger has distal phalanx, conveying the nail, the center phalanx and the proximal phalanx. The thumb is proximal to the ring finger to help to hold things easily.
