What is the anatomy of the tibia and fibula?
In this anatomy lesson, I’m going to cover the anatomy of the tibia and fibula bones of the anatomical leg, which is the section between the knee and ankle. These two leg bones are part of the appendicular skeleton, and anatomists classify them as long bones.
What is the proximal tibiofibular joint?
This is going to articulate (form a joint) with the lateral condyle of the tibia bone, forming the proximal tibiofibular joint. It also provides attachment for the biceps femoris and fibularis longus, as well as various ligaments.
What is the distal end of the tibia called?
Articular surface of the tibia – The distal end of the tibia will transfer weight to the foot at its articulation with the talus bone, forming the ankle joint. Medial malleolus – On the medial side of the tibia’s distal end, there is a rounded bony area with a projection called the medial malleolus.
Is the lateral malleolus the same as the tibia?
Like the medial malleolus, this articulates (forms a joint) with the talus bone of the foot (see foot bones) and allows for the attachment of ligaments. Although the fibula bone is smaller and thinner than the tibia, the lateral malleolus of the fibula is larger than the medial malleolus of the tibia.
What articulates with tibia and fibula?
Lateral Distal End The lateral aspect of the distal tibia forms the fibular notch, creating an articulation between the distal tibia and fibula, the distal tibiofibular joint.
What does the distal fibula articulate with?
The distal end of the fibula forms the lateral malleolus which articulates with the lateral talus, creating part of the lateral ankle. The posterior and lateral tibia form the posterior and medial malleolus, respectively.
Does the fibula articulate with the talus?
Articulations. The talus is part of a group of bones in the foot which are collectively referred to as the tarsus. The talus articulates with four bones - the tibia, fibula, calcaneus and navicular.
What ligaments attach to the distal fibula?
The distal tibia and fibula is stabilized by four ligaments: the interosseous membrane, anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, and transverse tibiofibular ligament. The posterior talofibular ligament runs from the posterior distal fibula to the posterior talus.
What is the distal fibula?
Distal fibular fractures are the most common type at the ankle and are usually the result of an inversion injury with or without rotation. They are the extension of a lateral collateral ligament injury.
What is the fibula connected to?
The fibula is connected to the tibia through a web of connective tissue that runs nearly the entire length of the fibular shaft. The proximal tibiofibular joint is held in place with the lateral fibular collateral ligament.
Where is the distal end of fibula?
The distal end of the fibula forms the lateral malleolus of the lower limb. This is a bony projection noted on the lateral surface of the ankle, which is complementary to another bony projection on the medial aspect of the ankle called the medial malleolus (formed by the tibia).
Which end of the tibia expands to form a prominence on the inner ankle?
Distal end of the tibia that expands to form a prominence on the inner ankle
Where is the entire arm and shoulder?
entire arm & shoulder to the border of the neck
Why does bone soften?
Softening of adult bone due to a disorder in calcium and phosphorus metabolism
Which tarsal bone articulates with the tibia?
The body of the talus articulates with the tibia, malleoli, and calcaneus. The neck of the talus lies between the head and body. The calcaneus is the largest and strongest bone of the foot.
What part of the tibia articulates with the femur?
The proximal tibia consists of the expanded medial and lateral condyles, which articulate with the medial and lateral condyles of the femur to form the knee joint. Between the tibial condyles is the intercondylar eminence.
Which tarsal bone articulates with the tibia and fibula quizlet?
The tibia and fibula articulate with the talus bone of the ankle to form this.
Which foot bone articulates with the tibia?
Tarsal Bones The most superior bone is the talus. This has a relatively square-shaped, upper surface that articulates with the tibia and fibula to form the ankle joint.
Which bone supports the most body weight?
At the same time, the bones and joints of the leg and foot must be strong enough to support the body’s weight while remaining flexible enough for movement and balance. The femur, or thigh bone, is the largest, heaviest, and strongest bone in the human body.
Which bone is the weight bearing bone of the leg?
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 is the function of femur bone?
The femur is the longest, heaviest, and strongest bone in the human body. The main function of the femur is weight bearing and stability of gait. An essential component of the lower kinetic chain. The upper body’s weight sits on the 2 femoral heads.
