Origin of the Tibia

Known as the shinbone, is the larger of the two bones in the lower leg. Biggest bone.

Function of the Tibia

Bears the most weight (walking, running, standing) and provides attachment in muscles.

The Tibia forms what two major joints

Knee joint and Ankle joint. These joints allow for movement/range of motion and stability in the lower leg.

Know about the lateral fibula

Smaller of the two bones in the lower leg, located on the outer side of the tibia (shinbone). Not part of the tibia, no weight. Plays a crucial role in stabilizing the ankle joint and provides attachment points for several muscles

Structure of the lateral fibula

Head- proximal end of the fibula, slightly enlarged and rounded, forms the proximal tibiofibular joint.

Lateral Fibula

Neck:

Shaft:

Lateral Malleolus:

Neck: A narrow region just below the head

Shaft: The long, cylindrical portion of the fibula that extends down the length of the bone. Three surfaces and three boarders

Lateral Malleolus: Distal end of the fibula, forming the outer bump of the ankle. It articulates with the talus bone and provides stability to the ankle joint.

Know about the structure of the patella

Also known as the kneecap, is a unique bone in the body. Classified as a sesamoid bone (floating bone). Develops within a tendon (ridges in middle)

Structure of the patella

Triangular shape- patella has a distinct triangular shape

Anterior surface: The surface is rough and provides attachment points for the quadriceps tendon and patellar ligament.

Posterior surface: This surface is smooth and divided into two articular facets for the femur.
