Bones of the lower limb

Colloquially, the lower limbs are the legs. However, in anatomy the term leg

has a more precise meaning and corresponds to the calf, that is, the

portion of the lower limb located between the knee and the ankle.

Ball joint

Colloquially called kneecap

(whose accepted medical

terminology is "patela") is a

bone of the leg, the sesamoid

(being wrapped by the distal

tendon of the quadriceps

crural) being the largest in

the human body. It is in even

number and is a constant

bone.

Function

Among its main functions are:

Acts as a support point by

increasing the lever arm of

the quadriceps. It guides the

forces between the femoral

component of the quadriceps

and the patellar tendon. It

protects the deep anatomy of

the knee and the quadriceps

tendon from friction forces.

Tibia

The tibia is a long,

triangular prism shaped

bone, located in the

anterior and inner part of

the leg; presents two

curvatures of the

opposite direction: the

superior, concave to the

outside; another inferior,

concave inward (in the

form of S italics).

Function

The tibia, is the strongest

bone of the two bones of

the leg below the knee in

vertebrates. Connect the

knee with the bones of the

ankle. It is commonly

recognized as the

strongest bone in the

body's load.

Femur

The femur is the thigh

bone, the second

segment of the lower

limb. It is the longest,

strongest and

voluminous bone of the

human body, 1 and of

most mammals.

Function

The femur is the only bone of

the thigh, it serves as a

fixation point for all the

muscles that exert their

strength on the hip and knee

joints. Some biarticular

muscles - which cross the

two joints, like the twin and

plantar muscles.

Commentary

The bones of the lower limb help us to sustain our body without them it would not be

possible for us humans to have the ability to sustain ourselves.
