A diagram of foot helps us to understand its structure and function. The foot diagram with labels shows its bones, muscles, ligaments, and tendons. The foot supports the body’s weight, facilitates movement, and maintains balance. It consists of the forefoot, midfoot, and hindfoot, including the toes, metatarsals, tarsal bones, and calcaneus (heel bone). The arches of the foot provide shock absorption and help distribute body weight during standing and walking.
Given below is a well-labelled diagram of foot:
Anatomy of Foot
The foot diagram shows the structure as a complex structure consisting of three main sections: the forefoot, midfoot, and hindfoot. These sections include bones such as the metatarsals, tarsals, and phalanges, as well as various muscles, ligaments, tendons, nerves, and blood vessels. The structure of the foot is explained below:
Hindfoot
The hindfoot is the section of the foot that starts below the ankle joint and ends at the Chopart joint. It’s made up of two bones: the talus bone, also known as the ankle bone, and the calcaneus bone, also known as the heel bone.
- Calcaneus (heel bone): This large bone forms the heel of the foot and provides attachment for the Achilles tendon.
- Talus: Positioned above the calcaneus, the talus bone connects the foot to the leg bones ( tibia and fibula) at the ankle joint.
Midfoot
The midfoot is the middle region of the foot, where the arch is formed by a cluster of small bones, and five long bones (metatarsals) extend to the toes.
- Tarsal bones: There are five tarsal bones that forms the arches of the foot, including the talus, calcaneus, navicular, cuboid and cuneiform bones. These bones contribute to the foot stability and flexibility.
Forefoot
The forefoot is the front part of the human foot, and includes the ligaments, muscles, and metatarsal bones. It also contains the phalanges, or toe bones.
- Metatarsal bones: Five long bones located between the midfoot and toes. They provide support and act as levers during walking and running.
- Phalanges: Each toe contains three phalanges, except for the big toe which has two. These bones allow for movement and balance.
Muscles, Tendons, Ligaments and Nerve
The diagram of foot shows various muscles in the foot, such as the intrinsic muscle (located within the foot) and extrinsic muscles (originating from the leg), control movement and provide support.
- Tendons connect muscles to bones, allowing the movement of the foot and toe.
- Ligaments stabilize the joints of the foot, preventing excessive movement and providing support.
- Nerves innervate the foot, providing sensory feedback for touch, temperature, pressure and proprioception (awareness of body position).

Arches of the Foot
The human foot has three arches: the medial longitudinal arch, the lateral longitudinal arch, and the anterior transverse arch. These arches are shaped by the tarsal and metatarsal bones, and braced by tendons and ligaments of the foot. The medial arch is the highest of the two longitudinal arches.
- Longitudinal arches (medial and lateral): These arches run along the length of the foot and help distribute body weight, absorb shock and provide flexibility.
- Transverse arch: This arch runs across the foot, contributing to its rigidity and stability.

Conclusion: Diagram of Foot
The labeled diagram of foot shows it consists of three main part: the forefoot, midfoot, and hindfoot. It has various bones, muscles, ligaments, and tendons, that together support weight-bearing activities and facilitate movement. The arches of the foot, including the medial longitudinal, lateral longitudinal, and transverse arches, provide shock absorption and distribute forces during locomotion. Nerves and blood vessels traverse the foot, enabling sensation and ensuring adequate circulation. Foot diagram is an easy way to learn the foot anatomy.

FAQs on Diagram of Foot
What is the Foot Diagram?
A foot diagram illustrates the anatomy of the human foot, highlighting its various structures such as bones, joints, muscles, ligaments, tendons and nerves.
What is Foot Structure?
The foot’s structure includes bones, muscles, tendons, ligaments, nerves and blood vessels, organised into hindfoot, midfoot and forefoot sections. Together, these components support weight, facilitate movement, absorb impact and ensure balance and stability.
How Many Bones in the Foot?
The human foot has 26 bones. The bones are divided into three parts: Tarsal bones: 7 bones, Metatarsal bones: 5 bones, and Phalanges: 14 bones.
How Many Muscles are in the Foot?
The human foot has 29 muscles, including 10 that originate outside the foot and 19 intrinsic muscles.
What are the Ligaments Under the Foot?
The main ligaments under the foot includes the plantar fascia, plantar calcaneocuboid ligament, long plantar ligament, plantar calcaneonavicular ligament, short plantar ligament. They provide stability, support and help maintain the foot’s structural integrity during movement.
What are the Parts of a Foot?
The main parts of a foot include the toes, arch, heel, and sole, each playing a crucial role in supporting body weight, balance, and mobility.
