Tibia and Fibula Memory Trick Also, little starts with the letter “l,” which can help you remember that this bone is always on the lateral side.
Is the tibia on the medial side of the leg?
Tibia. The tibia , or shinbone, is the main weight-bearing bone in the lower leg. It is on the medial side of either leg, meaning it is closer to the midline of the body.
Where is the tibia located?
lower legTibia 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.
Where is the tibia located in the human body?
lower legThe tibia is the shinbone, the larger of the two bones in the lower leg. The top of the tibia connects to the knee joint and the bottom connects to the ankle joint. Although this bone carries the majority of the body's weight, it still needs the support of the fibula.
What is the tibia in anatomy?
The tibia is one of two bones that comprise the leg.[1] As the weight-bearing bone, it is significantly larger and stronger than its counterpart, the fibula. The tibia forms the knee joint proximally with the femur and forms the ankle joint distally with the fibula and talus.
Is tibialis anterior?
The tibialis anterior is one of four muscles in the anterior compartment of the leg. The others include extensor digitorum longus (EDL), extensor hallucis longus (EHL), and fibularis tertius. The deep peroneal nerve innervates all muscles and is perfused by the anterior tibial artery.

The medial compartment of thigh is one of the fascial compartments of the thigh and contains the hip adductor muscles and the gracilis muscle. Cross-section through the middle of the thigh. (Medial compartment is at center right.)
Is tibia axial or appendicular?
The appendicular skeleton is everything else. It's everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
What part of the leg does the tibia form?
tibia, also called shin, inner and larger of the two bones of the lower leg in vertebrates—the 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.
Which bone of the lower leg is located laterally?
fibulaThe tibia (also called the shinbone) is located near the midline of the leg and is the thicker and stronger of the two bones. The fibula, also called the calf bone, is significantly smaller and is situated on the lateral (farther from the midline) side of the tibia.

Is the fibula behind the tibia?
The fibula is located on the lateral (outside) of the tibia, slightly posterior (to the back) and offsets a little below. The proximal (top) end of the fibula is articulated with the lateral condyle of the tibia, just below the knee. That is called the proximal tibiofibular joint.
Which side of the tibia is the distal end?
The distal end of the tibia is much smaller than the proximal end and presents five surfaces; it is prolonged downward on its medial side as a strong pyramidal process, the medial malleolus. The lower extremity of the tibia together with the fibula and talus forms the ankle joint .
What are the three surfaces of the tibia?
These three borders form three surfaces; the medial, lateral and posterior.
What is the intercondylar eminence?
Between the articular facets in the intercondylar area, but nearer the posterior than the anterior aspect of the bone, is the intercondyloid eminence ( spine of tibia ), surmounted on either side by a prominent tubercle, on to the sides of which the articular facets are prolonged; in front of and behind the intercondyloid eminence are rough depressions for the attachment of the anterior and posterior cruciate ligaments and the menisci.
What are the four joints that make up the tibia?
Joints. The tibia is a part of four joints; the knee, ankle, superior and inferior tibiofibular joint . In the knee the tibia forms one of the two articulations with the femur, often referred to as the tibiofemoral components of the knee joint. This is the weightbearing part of the knee joint.
How much force does the tibia take?
The tibia has been modeled as taking an axial force during walking that is up to 4.7 bodyweight. Its bending moment in the sagittal plane in the late stance phase is up to 71.6 bodyweight times millimetre.
What is the anterior surface of the condyles?
The anterior surfaces of the condyles are continuous with one another, forming a large somewhat flattened area; this area is triangular, broad above, and perforated by large vascular foramina; narrow below where it ends in a large oblong elevation, the tuberosity of the tibia, which gives attachment to the patellar ligament; a bursa intervenes between the deep surface of the ligament and the part of the bone immediately above the tuberosity.
What is the ossification of the tibia?
Anterior aspect. The tibia is ossified from three centers; a primary center for the diaphysis (shaft) and a secondary center for each epiphysis (extremity). Ossification begins in the center of the body, about the seventh week of fetal life, and gradually extends toward the extremities.
What is the Tibia
Tibia is one of the two long leg bones of the lower leg. It is a weight-bearing bone, and also known as the shinbone or shankbone.
Where is the Tibia Located
As mentioned, the tibia is located in the lower leg, extending from the knee to the ankle. More precisely, it is situated on the distal side of the femur and the proximal side of the talus of the foot. The tibia is also located medially to the other bone of the lower leg, called the fibula.
Anatomy – Parts of the Tibia
It is a long bone with two ends, proximal and distal, and an intervening shaft. The part lying on the side of the knee is known as the proximal tibia, whereas the part lying on the side of the foot is known as the distal tibia.
Muscles Attached
Tibia has many muscles attached to it. Some originate from the bone, whereas some get inserted into it.
What is the tibia?
The tibia is the main bone of the lower leg, form ing 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. In this article, we shall look at anatomy ...
What is the distal end of the tibia?
Distal. The distal end of the tibia widens to assist with weight-bearing. The medial malleolus is a bony projection continuing inferiorly on the medial aspect of the tibia. It articulates with the tarsal bones to form part of the ankle joint.
What is a fracture of the proximal tibia called?
Fractures of the proximal tibia are known as tibial plateau fractures; the condyles may be broken and injury to the menisci and ligaments of the knee is not uncommon. These fractures are classified using the Schatzker classification, and if very displaced will likely required operative management.
Which structure articulates with the femoral condyles to form a flat surface?
The proximal tibia is widened by the medial and lateral condyles, which aid in weight-bearing. The condyles form a flat surface, known as the tibial plateau. This structure articulates with the femoral condyles to form the key articulation of the knee joint.
What are the three surfaces of the tibia?
The shaft of the tibia is prism-shaped, with three borders and three surfaces; anterior, posterior and lateral. For brevity, only the anatomically and clinically important borders/surfaces are mentioned here. Anterior border – palpable subcutaneously down the anterior surface of the leg as the shin.
Where is the fibula bound to the tibia?
On the posterior surface of the tibia, there is a groove through which the tendon of tibialis posterior passes. Laterally is the fibular notch, where the fibula is bound to the tibia – forming the distal tibiofibular joint.
What condyles articulate with the femoral condyles to form the knee joint?
The tibial condyles articulate with the femoral condyles to form the knee joint. caption] Shaft. The shaft of the tibia is prism-shaped, with three borders and three surfaces; anterior, posterior and lateral. For brevity, only the anatomically and clinically important borders/surfaces are mentioned here.
What is the proximal end of the tibia called?
Medial and lateral condyles – The proximal end (or top) of the tibia widens out from the shaft and forms a medial and lateral condyle. A condyle is a rounded projection on a bone that is going to articulate (or form a joint) with something. Medial is a directional term that tells us it is toward the midline of the body, ...
What is the tibia and fibula bone?
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 bump on the anterior side of the tibia called?
Tibial tuberosity – Between the condyles and the shaft, you’ll notice a bump on the anterior side of the tibia called the tibial tuberosity. That’s all a tuberosity is: it’s a fancy word that means bump or small rounded area. This structure allows for the attachment of the patellar ligament.
What is the intercondylar eminence?
Intercondylar eminence – Between the articular surface of the medial and lateral condyles is an area called the intercondylar eminence.
What is the membrane between the tibia and fibula?
First, you’ll notice this web-like structure called the interosseous membrane (or middle tibiofibular ligament). The prefix “inter” means between, and osseous refers to the bones. So this is literally the membrane between the bones. (Note, the radius and ulna bones also have this membrane.) This membrane keeps the tibia and fibula together ...
What is the articular surface of the medial and lateral condyles?
Articular surface of medial and lateral condyles – The top of these condyles have a concave surface, which you can see on the posterior view of the tibia. These are called the articular surface of the medial and lateral condyles. This is going to articulate with the medial and lateral condyles of the femur (thigh) bone, ...
Where is the malleolus located?
Malleolus comes from a Latin word that means “little hammer,” and this area articulates with the talus bone of the foot. This is the bony area you feel on the inside of your ankle. It can serve as a landmark when locating the posterior tibial pulse point.
Overview
Structure
In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints.
The ossification or formation of the bone starts from three centers; one in the shaft and one in each extremity.
Clinical significance
Fractures of the tibia can be divided into those that only involve the tibia; bumper fracture, Segond fracture, Gosselin fracture, toddler's fracture, and those including both the tibia and fibula; trimalleolar fracture, bimalleolar fracture, Pott's fracture.
Society and culture
In Judaism, the tibia, or shankbone, of a goat is used in the Passover Seder plate.
Other animals
The structure of the tibia in most other tetrapods is essentially similar to that in humans. The tuberosity of the tibia, a crest to which the patellar ligament attaches in mammals, is instead the point for the tendon of the quadriceps muscle in reptiles, birds, and amphibians, which have no patella.
