How many carpal bones are there in total?

The total number of carpal bones in the human wrist is eight. These bones are organized into two rows, comprising a total of eight individual bones: the scaphoid, lunate, triangular (or triquetrum), pisiform, trapezium, trapezoid, capitate, and hamate. This arrangement allows for a high degree of flexibility and mobility in the wrist, enabling various movements essential for hand function.

Understanding the structure of these bones is important in fields related to anatomy and physiology, as well as in practices such as manicure and pedicure, where knowledge of hand and wrist anatomy can influence technique and safety during nail care procedures. The other options presented do not accurately reflect the anatomical configuration of the wrist, which is a crucial aspect in recognizing the structure and function of the skeletal system.
