The big toe, also known as the hallux, is the largest toe on the human foot. It plays a crucial role in balance and walking, providing stability and support during movement. The big toe has two bones, called phalanges, and is connected to the foot by ligaments and tendons. In addition to its structural importance, the big toe contains a rich supply of nerves and blood vessels. This helps with sensation and circulation. Proper care of the big toe is essential, as issues like bunions or ingrown toenails can lead to discomfort and affect overall foot health.
