Toe

You have toes on your feet.

Most people have five toes on each foot. They help you stay balanced. They also help you walk.

Small bones are inside each toe. The big toe has only two bones. The other toes have three bones.

Every toe has a nail on top. Skin covers your toes too.

Some people are born with extra toes. This is a special way to grow.

Your toes help you move your feet. They are very important for walking.

Most people have five toes on each foot.

These toes help you balance and walk. They also help you push off the ground.

Inside your toes are small bones called phalanges.

Most toes have three of these bones. The big toe, or hallux, only has two. These bones connect at joints. We call these interphalangeal joints.

Muscles and tendons help your toes move. Tendons are like strong cords. They connect muscles to your bones. Most toes move together. This is because of how the muscles attach. However, the big toe and little toe have their own special muscles.

Nerves give your toes feeling. They tell your brain about touch.

Different nerves cover different parts of the toe.

Sometimes, people are born with more than five toes. This is called polydactyly.

Some people also have different toe shapes. These shapes can change how shoes fit. Small injuries can happen too. You might stub a toe. This can hurt the small joints.

Toes are the small digits at the end of a foot. They play a huge role in how animals move around. Some animals, like cats, walk on their toes. This way of walking is called digitigrade. Humans are different because we are plantigrade. This means we walk on the soles of our feet. Other animals, called unguligrade, walk on the hard tips of their toes using hooves.

Inside your toes, there are small bones called phalanges. Most toes have three of these bones: the proximal, middle, and distal bones. The big toe, or hallux, is special because it only has two bones. These bones connect at places called interphalangeal joints. The first bone of the toe connects to the foot at the metatarsophalangeal joint.

Muscles and tendons make the toes move. Most toes move together because of how the muscles attach to the bones. However, the hallux and the little toe have their own unique muscles to help them move separately.

Words for toes have long histories. The Old English word for toe is "tā". This comes from a group of very old languages. It might have once meant "fingers" too. Many different languages use one word for both fingers and toes. In Latin, people used special names for the big toe. Today, we use a blend of those old names.

There is a lot of variety in how toes look. Most people have five toes on each foot. Some people are born with more than five, which is called polydactyly.

You might also see a toe that is longer or shorter than others. For example, some people have a longer second toe instead of a longer big toe. This is sometimes called Morton's toe. Scientists have even studied how toe shapes can relate to where a person's family comes from.

Toes are very important for your daily life. They help you keep your balance while standing up. They also help you push off the ground when you walk.

Sometimes, toes can get hurt. You might stub a toe on something hard. This can hurt the small joints. It is also important to wear shoes that fit well. If shoes are too tight, they can cause the toes to move out of place or cause pain.

Toes are the digits located at the end of a tetrapod's foot. They serve vital roles in movement, balance, and weight-bearing for many different animals. The way an animal moves affects how its toes interact with the ground. For example, cats are described as digitigrade because they walk on their toes. Humans and other animals are plantigrade, meaning they walk on the soles of their feet. There are also unguligrade animals, which walk on hooves located at the very tips of their toes.

Inside the human toe, the structure is made of specific bones called phalanges. Most toes consist of three phalanx bones: the proximal, middle, and distal bones. The hallux, or big toe, is an exception to this rule. The hallux only contains two phalanx bones, which are the proximal and distal ones. A minority of people may also lack a middle bone in their little toe. These bones connect at joints known as interphalangeal joints. Additionally, the proximal phalanx of each toe connects to the metatarsal bone of the foot at the metatarsophalangeal joint.

Movement in the toes is driven by muscles and tendons. Most toe movement involves flexion, which is moving toward the sole, and extension, which is moving toward the back of the foot. For the four smaller toes, the flexor digitorum brevis and extensor digitorum brevis muscles govern this action. Because these muscles attach to the sides of the bones, it is impossible to move individual toes independently. However, the hallux and the little toe have unique muscle sets. The hallux is primarily moved by the flexor hallucis longus and the flexor hallucis brevis. The little toe is controlled by the flexor and abductor digiti minimi.

Sensation and blood supply are also carefully organized in the toes. Blood reaches the toes through the digital branches of the plantar metatarsal arteries. The blood then drains into the dorsal venous arch of the foot. Sensation to the skin is provided by five different nerves. The superficial fibular nerve supplies the top of the toes, except for the area between the hallux and the second toe. The deep fibular nerve supplies that specific gap. The sural nerve provides sensation to the outer surface of the fifth toe. On the bottom, the medial plantar nerve serves the hallux and the inner three-and-a-half toes. The lateral plantar nerve covers the little toe and half of the fourth toe.

There is significant natural variation in how toes appear among humans. Most people have five toes on each foot, but some are born with more. This condition is known as polydactyly.

Other variations include syndactyly or arachnodactyly. Toe length also varies due to genetics. In most humans, the hallux is longer than the second toe. However, a dominant gene can cause a longer second toe, a trait called Morton's toe or Greek foot. Some people may also have a short hallux that turns inward due to the rare genetic disease fibrodysplasia ossificans progressiva. Research by the U.S. Army has even shown that toe shape and breadth can correlate with ethnicity.

Because toes are essential for walking, they are susceptible to various clinical issues. A common injury is a stubbed toe, which is a sprain or strain of the interphalangeal joints. Another injury, called turf toe, occurs when the toe is strained where it joins the foot. Improperly sized shoes can lead to misalignment or orthopedic problems. Some people suffer from Morton's neuroma, which causes pain and numbness between the third and fourth toes. The big toe is also a frequent site for ingrown nails and gout attacks. Deformities like hammer toe, trigger toe, or claw toe can also occur. These can be caused by dislocations or conditions like diabetes mellitus and rheumatoid arthritis.

The history of the word "toe" reveals much about language evolution. The Old English term was "tā," which is a contraction of "tō." This word comes from Proto-Germanic roots and may have originally referred to fingers as well. Many Indo-European languages use a single word to describe both fingers and toes. In classical Latin, specific terms like "pollex" were used for the thumb. The modern term for the big toe is actually a blend of older Latin forms. From an evolutionary perspective, scientists like Haeckel have traced the five-toed pattern from fish fins through amphibian ancestors.
