Solution:
Sesamoid bones are small, round bones that are embedded in tendons. These bones are commonly found in the tendons of the hands, knees, and feet, for example, patella is a sesamoid bone. Fibrous joints are present between the cranial bones.
Tetany is caused due to the involuntary contraction of muscles, which may be caused by disease or other conditions that increase the action potential frequency of muscle cells or the nerves that innervate them. Tetany is characterized by contraction of distal muscles of the hands and feet, is associated with tingling around the mouth and distally in the limbs. The usual cause of tetany is lack of calcium. An excess of phosphate (high phosphate-to-calcium ratio) can also trigger the spasms.
