The lower leg is comprised of two bones, the tibia and the smaller fibula. The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint).
What are the bones of the lower leg and foot?
In the lower leg are two bones called the tibia (shin bone) and the fibula. These bones articulate (connect) to the Talus or ankle bone at the tibiotalar joint (ankle joint) allowing the foot to move up and down.
What are the 3 major bones in the leg?
At the knee joint, three bones connect: your femur, tibia, and patella. Those three large bones require an equally large joint to connect them.
How many bones are found in the lower leg?
There are 30 bones in each lower limb. These are the femur, patella, tibia, fibula, seven tarsal bones, five metatarsal bones, and 14 phalanges.
What bones comprise ankle?
- The shin bone (tibia)
- The thinner bone running next to the shin bone (fibula)
- A foot bone that sits above the heel bone (talus)
What is your shin bone called?
Tibia and fibula are the two long bones located in the lower leg. The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two.
What's the fibula bone?
The fibula, sometimes called the calf bone, is smaller than the tibia and runs beside it. The top end of the fibula is located below the knee joint but is not part of the joint itself. The lower end of the fibula forms the outer part of the ankle joint.
What bones are below the knee?
Tibia– The shin bone, the larger of the two leg bones located below the knee cap. Fibula – The smaller of the two leg bones located below the knee cap.
What is the name of the shin bone?
The tibia, or shinbone, is the most commonly fractured long bone in the body. A tibial shaft fracture occurs along the length of the bone, below the knee and above the ankle.
What are the parts of leg?
The bones of the leg consist of the femur, tibia and fibula, tarsals, metatarsals and phalanges. A femur is the longest and heaviest bone of the body. Actually femur, tibia and fibula bones together support the shank of the leg.

Is knee upper or lower leg?
Knee anatomy and function. The knee joins the upper leg and the lower leg. It’s also the largest joint in the body. In addition to bearing the weight of the upper body, the knee allows for walking, running, and jumping.
What are the metatarsal bones?
The metatarsal bones are the bones of the forefoot that connect the distal aspects of the cuneiform (medial, intermediate and lateral) bones and cuboid bone to the base of the five phalanges of the foot. There are five metatarsal bones, numbered one to five from the hallux (great toe) to the small toe.
What are the 7 bones in the ankle called?
The tarsal bones are 7 in number. They are named the calcaneus, talus, cuboid, navicular, and the medial, middle, and lateral cuneiforms.
What is the name of the bone that is in the lower leg that is involved with most ankle sprains?
Fibula (calf bone). Malleolus (a bump that sticks out from each side of the ankle).
What is distal tibia?
Ankle Anatomy and Biomechanics The distal tibia, distal fibula, and talus articulate to form the bony structure of the ankle joint. The distal tibial articular surface, also known as the tibial plafond, is a quadrilateral surface that is wider anteriorly.
What is the outer bone in the lower leg called?
fibula, outer of two bones of the lower leg or hind limb, presumably so named (fibula is Latin for “brooch”) because the inner bone, the tibia, and the fibula together resemble an ancient brooch, or pin. In humans the head of the fibula is joined to the head of the tibia by ligaments and does not form part of the knee.
What is humerus bone?
The humerus — also known as the upper arm bone — is a long bone that runs from the shoulder and scapula (shoulder blade) to the elbow. … A humerus shaft fracture, on the other hand, is one that is localized at the mid portion of the upper arm.
Is tibia in front of fibula?
The tibia is found on the medial side of the leg next to the fibula and closer to the median plane or centre-line. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement.
What type of bone is the ulna?
The ulna forms the skeleton of the medial part of the forearm and is a long bone, consisting of an expanded proximal end, a shaft and a head at the distal end.
What is the name of the bones for both the toes and fingers?
Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2.
What is the bottom of the tibia called?
At the lower end of the tibia there is a medial extension (the medial malleolus), which forms part of the ankle joint and articulates with the talus (anklebone) below; there is also a fibular notch, which meets the lower end of the shaft of the fibula.
Which side is tibia and fibula?

What are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
What muscle is below the knee?
Your calf muscle sits in the back of your lower leg. It starts below your knee and extends to your ankle.
What is the bottom of the femur called?
The distal femur is where the bone flares out like an upside-down funnel. The distal femur is the area of the leg just above the knee joint.
What are the four components in the lower leg?
The lower leg is divided into four compartments that contain the various muscles of the lower leg—anterior, lateral, posterior and deep posterior.
What part of the leg is the calf?
The calf (Latin: sura, plural calves) is the back portion of the lower leg in human anatomy. The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon.
What are the lower parts of the body?
The lower extremity refers to the part of the body from the hip to the toes. The lower extremity includes the hip, knee, and ankle joints, and the bones of the thigh, leg, and foot. Many people refer to the lower extremity as the leg. … The proper way to describe the lower limb is the lower extremity.
What muscle is in front of lower leg?
The tibialis anterior muscle is the muscle located in the front part of the shin bone of your lower leg.
What are the 14 phalanges bones?
The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two.
What is phalanges foot?
The phalanges (single: phalanx) of the feet are the tubular bones of the toes. The second to fifth toes each contain a proximal, middle and distal phalanx whereas the great toe (hallux) only contains a proximal and distal phalanx.
