Structure of the tibia

The tibia is the second largest bone in the body and it is a key weight-bearing structure. In humans the tibia forms the lower half of the knee joint above and the inner protuberance of the ankle below.

The structure of the bone varies at different levels but a section taken from the same level in the tibia from animals of the same age presents a reasonably constant picture.

Structure of the tibia. The tibia shin bone is a long bone of the leg found medial to the fibula. It is also the weight bearing bone of the leg which is why it is the second largest bone in the body after the femur. Fun fact here is that tibia is the Latin word for tubular musical instruments like the flute.

The tibia is the main bone of the lower leg forming what is more commonly known as the shin. It expands at its proximal and distal ends. Articulating at the knee and ankle joints respectively.

The tibia is the second largest bone in the body and it is a key weight-bearing structure. The tibia runs medial to the fibula from just below the knee joint to the ankle joint and is connected to the fibula by the interosseous membrane. The proximal portion of the tibia consists of a medial and lateral condyle which combine to form the inferior portion of the knee joint.

The tibia sometimes known as the shin bone is the larger and stronger of the two lower leg bones. It forms the knee joint with the femur and the ankle joint with the fibula and tarsus. Many powerful muscles that move the foot and lower leg are anchored to the tibia.

The support and movement of the tibia is essential to many activities. The tibia is also known as the shinbone and is the second largest bone in the body. There are two bones in the shin area.

The tibia and fibula or calf bone. Tibia inner and larger of the two bones of the lower leg in vertebratesthe other is the fibula. In humans the tibia forms the lower half of the knee joint above and the inner protuberance of the ankle below.

Learn more about the tibia in this article. The tibia and fibula are approximately equal in length but are different in structure and function. The tibia is large transmits most of the stress of walking and has a broad accessible subcutaneous surface.

The fibula is slender and plays an important role in ankle stability as well as taking one sixth of the load. Since a spring-like elastic element can generally work more rapidly than a muscular structure under a neural control Gronenberg 1996. Ache and Matheson 2013 can the presence of the elastic organ or fibers in the distal tibia of the insects suggests that a rapid and reliable detachment of the pretarsus is an important step in each cycle of.

The distal end of the tibia articulates with the trochlea of the talus a pulley-shaped rounded superior articular surface. The trochlea of the talus is convex in the parasagittal plane and slightly concave in the transverse plane. The distal end of the tibia is reciprocally shaped so that its congruent with the talar surface.

43 the talus and distal tibia. The trabecular structure of the talus is more divergent than the tibia having 44 thicker less uniformly aligned trabeculae in Pan compared to Homo. Differences in dorsiflexion at the 45 talocrural joint and in degree of mobility at the talonavicular joint are reflected in the distribution of.

The tibia is a role of four joints. The ankle knee superior and inferior tibiofibular joint. In the knee joint the tibia articulates one of the two connections with the femurThis is the weight-bearing part of the knee joint.

The tibiofibular joints are the joints of the tibia and fibula which provides very little movement. Tibia is a long bulky bone that lodges the anterior and internal portion of the leg next to the Fibula. Tibia loads the weight of our body from the femur bone and transmits the weight to the feet through the astragalus bone.

Subsequently the femur tibia is the largest bone.

The structure of the bone varies at different levels but a section taken from the same level in the tibia from animals of the same age presents a reasonably constant picture.

It has been shown that this variation in structure at different levels is directly related to. The tibia is classified as a long bone. It contains a diaphysis and two epiphyses.

The diaphysis constitutes the middle of the tibia while the epiphyses are rounded sections on the ends of the bone. Four joints include the tibia bone. The ankle knee and interior and superior tibiofibular joints.

This structure includes a left and right tubercle which resembles tiny devil horns and fossae to which the menisci and the cruciate ligaments attach. Tibial tuberosity Between the condyles and the shaft youll notice a bump on the anterior side of the tibia called the tibial tuberosity. Many strong ligaments surround the joint capsule of the knee to reinforce its structure and hold its bones in the proper alignment.

On the anterior surface of the knee the patella is held in place by the patellar ligament which extends from the inferior border of the patella to. THis video takes a look at the basic features of the bones of our lower leg including the tbia and fibulaVideo number- Anatomy 1- 34.
