lower legs  
human leg is the lower limb of the body, extending from the hip to the ankle, and including the thigh, the knee, and the cnemis.the largest bone in the human body, the femur, is in the leg.
function and cultural aspects  
legs are often used for standing, walking, jumping, running, kicking, and similar activities, and are a significant portion of a persons mass.
adolescent and adult females in many western cultures often remove the hair from their legs.toned, tanned, shaved legs are sometimes perceived as a sign of youthfulness and are often considered attractive in these cultures.
  lower extremity    bones in the lower legs  femur or thigh bone   
is the longest, most voluminous, and strongest bone of the mammalian bodies.it forms part of the hip and part of the knee.

the word femur is latin for thigh. in strict usage, femur bone is more proper than femur, as femur refers to thigh, and femur bone refers to the bone within it

the name of the bone itself comes from os femoris, although in modern medical usage the term femur is most often applied to the bone and not the thigh. in medical latin its genitive is always femoris, but in classical latin its genitive is often feminis, and should not be confused with case forms of femina, which means woman

  patella   patella or kneecap   

is a thick, triangular bone which articulates with the femur and covers and protects the front of the knee joint. it is the largest sesamoid bone in the human body

it is attached to the tendon of the quadriceps femoris muscle, which contracts to straighten the leg. the vastus intermedialis muscle is attached to the base of patella

the vastus lateralis and vastus medialis are attached to lateral and medial borders of patella respectively.   tibia  tibia  
is the larger of the two bones in the leg below the knee in vertebrates.

tibia or shin bone, in human anatomy, is found medial (towards the middle) and anterior (towards the front) to the other such bone, the fibula. it is the second-longest bone in the human body, the largest being the femur

the tibia articulates with the femur and patella superiorly, the fibula laterally and with the ankle inferiorly.   fibula  fibula or calf bone   

is a bone located on the lateral side of the tibia, with which it is connected above and below. it is the smaller of the two bones, and, in proportion to its length, the most slender of all the long bones

its upper extremity is small, placed toward the back of the head of the tibia, below the level of the knee-joint, and excluded from the formation of this joint. its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia, and forms the lateral part of the ankle-joint
