Fascia of the Palm
Below the dermis of the palm, there is a significant and tougher-than-average layer of fascia (connective tissue) that serves primarily as a protector to the underlying muscles. Despite the keratinized layer of epidermis on the palms, additional reinforcement is needed for general protection of the muscles in the area. On the back of the hands, the fascia is still significant, but not as tough as the palm.
