Your feet are the foundation of your body. They carry you through every step of your day, supporting your weight and helping you move around. But have you ever stopped to think about what makes up your feet and how they work? Understanding about parts of foot is necessary for keeping them healthy and happy.
Your feet are made up of following parts :
- Bones
- Muscles and tendons
- Ligaments
- Arches
- Joints
- Nerves
- Vessels
Lets get to know about all of them so you can have easy understanding. But knowing about your feet you can judge where problem lies in your feet and what you can do .
Bones of foot
Your feet is made up of several bones that work together to provide support and mobility. Let’s explore the different types of bones in the foot
Tarsals (7 Bones)
Heel Bone (Calcaneus): This is the largest bone in your feet, forming the heel. It helps support your weight when you stand or walk.
Ankle Bone (Talus): This bone sits between your lower leg bones and the heel bone. It helps transfer weight and forces from your leg to your feet.
Navicular Bone: Shaped like a boat, this bone supports the arch of your foot and helps maintain its flexibility.
Cuboid Bone: Located on the outer side of your foot, this bone helps stabilize your foot and connect the midfoot to the outer toes.
Medial Cuneiform: This wedge-shaped bone is on the inner side of your feet, connecting the navicular bone to the first and second metatarsal bones.
Intermediate Cuneiform: It is Positioned between your medial and lateral cuneiform bones, it supports the foot arch and helps distribute weight.
Lateral Cuneiform: It is Situated between your cuboid bone and the intermediate cuneiform, it helps distribute weight across the foot.
Metatarsals (5 Bones)
Big Toe Bone (First Metatarsal): The largest and strongest metatarsal bone, it bears a lot of weight when you walk or run.
Second Metatarsal: This bone runs next to the big toe bone and helps spread weight evenly across the ball of your feet.
Third Metatarsal: Positioned beside the second metatarsal, it provides support and stability to the middle of your feet.
Fourth Metatarsal: Located between the third and fifth metatarsals, it helps maintain your foot arch and support the adjacent toes.
Fifth Metatarsal: Found on the outer edge of your feet, it plays a crucial role in weight-bearing and balance, especially during side-to-side movements.
Phalanges (Toe Bones) - 14 Bones
Each toe has three phalanges, except the big toe, which has two:
- Proximal Phalanx: Closest to the metatarsal bone.
- Middle Phalanx: Between the proximal and distal phalanges.
- Distal Phalanx: At the tip of the toe.
Understanding the bones of your feet helps you recognize and address issues related to feet health and function. Next, we’ll explore how these bones work with muscles, tendons, ligaments, and joints to keep your feet moving smoothly and without pain.
Muscles and Tendons in the Foot
Understanding the roles of these muscles and tendons is essential for knowing the mechanisms of foot function and mobility.
Muscles
Flexor Hallucis Longus
Function: This muscle is responsible for bending your big toe downward, a movement known as toe flexion. It helps push off the ground when you walk, run, or jump.
Location: The flexor hallucis longus muscle originates from the back of your lower leg, crosses behind your ankle, and attaches to the bottom of your big toe.
Extensor Digitorum Longus
Function: The extensor digitorum longus muscle extends or straightens your toes, allowing you to lift them off the ground. This action is crucial for activities like walking, running, and maintaining balance.
Location: It originates from the front of your lower leg, travels down the top of your foot, and attaches to the toes.
Tendons
Plantar fascia
Function: The plantar fascia is a thick band of tissue located on the bottom of your foot. It plays a vital role in supporting the arch of your foot and absorbing shock during activities such as walking, running, and jumping.
Location: This tendon runs from the heel bone (calcaneus) to the base of the toes, providing structural support to the foot’s arch.
Ligaments of foot
Your foot has tough bands of tissue called ligaments that keep your bones together and provide stability to your joints. Let’s learn more about how these ligaments work and explore some important ones:
Role of Ligaments in Foot Stability
- Ligaments act like strong ropes that hold your foot bones together, keeping them stable and preventing excessive movement.
- They support your foot arches and help distribute weight evenly when you stand, walk, or run.
Important Ligaments in the Foot
Plantar Calcaneonavicular Ligament
Function: This ligament, also known as the “spring ligament,” supports your feet arch and prevents it from flattening too much when you walk or run.
Location: It’s found on the bottom of your foot, connecting your heel bone (calcaneus) to the navicular bone.
Deltoid Ligament
Function: The deltoid ligament is a strong, triangular-shaped ligament on the inner side of your ankle joint. It keeps the inner aspect of your ankle stable and prevents your foot from rolling inward too much.
Location: It starts from the inner ankle bone (medial malleolus) and attaches to various foot bones.
Anterior Talofibular Ligament
Function: This ligament is vital for preventing your foot from sliding too far forward relative to your ankle joint. It helps keep your ankle stable and prevents injuries.
Location: It stretches from the outer ankle bone (lateral malleolus) to the talus bone.
Understanding the roles of these ligaments is essential for maintaining foot stability and preventing injuries. They work together to keep your foot strong and steady, allowing you to move comfortably and confidently.
Joints of foot
In your feet, joints are where two or more bones meet and allow movement. Understanding these joints is crucial for comprehending how your feet functions.Lets have an easy understanding.
Types of Joints and Their Functions
- Hinge Joints: These joints allow movement in only one direction, like bending and straightening. They provide stability and support.
- Gliding Joints: These joints enable bones to glide over each other in various directions. They contribute to smooth movements and flexibility.
- Pivot Joints: Pivot joints allow rotation around an axis. They are essential for rotational movements, like turning your foot from side to side.
Important Joints in the Foot
Ankle joint
- Type: Hinge Joint
- Function: The ankle joint allows your feet to move up and down, like when you point your toes (plantarflexion) or pull them up towards your shin (dorsiflexion).
- Location: It’s formed by the lower end of the tibia (shinbone), the fibula (outer lower leg bone), and the talus bone (top of the feet).
Subtalar joints
- Type: Gliding Joint
- Function: The subtalar joint is responsible for side-to-side movement of the foot. It allows your foot to tilt inward (inversion) and outward (eversion) to adapt to uneven surfaces.
- Location: It’s located below the ankle joint, between the talus bone and the calcaneus (heel bone).
Metatarsophalangeal Joint
- Type: Hinge Joint
- Function: This joint allows movement between the metatarsal bones (the long bones in the middle of your feet) and the phalanges (toe bones). It enables you to bend and straighten your toes.
- Location: It’s found at the base of each toe, where the metatarsal bone meets the proximal phalanx bone.
Understanding the different types of joints and their functions in your feet is essential for maintaining mobility and preventing injuries.
Arches of foot
The arches of your foot are like natural shock absorbers, providing support, flexibility, and balance to your entire body. Let’s explore.
Overview of foot arches
Your foot has three arches.
Medial Longitudinal Arch: This arch runs along the inner side of your foot, from the heel to the ball of the foot.
Lateral Longitudinal Arch: This arch runs along the outer side of your foot, from the heel to the fifth metatarsal bone.
Transverse Arch: This arch runs across the middle of your foot, from side to side.
Types of Foot Arches
Flat Arches (Low Arches)
- Flat arches have minimal or no curvature, causing the entire sole of the feet to touch the ground when standing.
- People with flat arches may experience overpronation (inward rolling of the feet) and may be more prone to foot conditions like plantar fasciitis and arch pain.
Normal Arches (Medium Arches)
- Normal arches have a moderate curvature, allowing the feet to maintain a balanced position when standing.
- People with normal arches usually have a good balance between flexibility and support, reducing the risk of feet problems.
High Arches (Cavus Arches)
- High arches have a pronounced curvature, with only a small portion of the feet making contact with the ground when standing.
- People with high arches may experience underpronation (outward rolling of the foot) and may be more prone to issues like ankle instability and stress fractures.
Importance of Arch Support and Foot Health
Provides Stability: Arch support helps distribute your body weight evenly across your feet, reducing pressure on specific areas and promoting proper alignment.
Prevents Injuries: Proper arch support can help prevent common foot problems like plantar fasciitis, arch pain, and heel spurs by providing cushioning and shock absorption.
