The tarsals correspond to the carpal bones of the upper limb. In humans the tarsals, in combination with the metatarsal bones, form a longitudinal arch in the foot—a shape well adapted for carrying and transferring weight in bipedal locomotion.]]> 2018-10-15 14:11:52 UTC https://padlet.com/apar0353/sk1i8mdnxb1v/wish/292830825 apar0353 https://padlet.com/apar0353/sk1i8mdnxb1v/wish/293313860
Metatarsals are part of the bones of the mid-foot and are tubular in shape. They are named by numbers and start from the medial side outward. The medial side is the same side as the big toe.

The human body has a total of fifty-six phalanges, with three phalanges for each finger and toes except for two phalanges per thumb and large toes in feet. The phalanges are normally linked with each other at hinge-like inter-phalangeal joints which is for extension purpose. In many cases, the phalange bones are fused with each other]]> 2018-10-16 13:26:09 UTC https://padlet.com/apar0353/sk1i8mdnxb1v/wish/293315747 apar0353 https://padlet.com/apar0353/sk1i8mdnxb1v/wish/293319069 Calcium and vitamin D work together to protect your bones—calcium helps build and maintain bones, while vitamin D helps your body effectively absorb calcium.
