The '''femur''' is the thigh bone. In [[humans]], it is the [[longest body part|longest]], most voluminous, and strongest [[bone]]. The average human femur is 48 centimeters (19 in) in length and 2.34 cm (0.92 in) in diameter and can support up to 30 times the weight of an adult.<ref>{{cite web|url=http://thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com/long254.html|title=The Longest Human Bone|publisher=thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com|language=English|accessdate=2007-12-14}}</ref> It forms part of the [[hip]] (at the acetabulum) and part of the [[knee]].
The word ''femur'' is [[Latin]] for ''thigh''. Theoretically in strict usage, ''femur bone'' is more proper than ''femur'', as in classical Latin ''femur'' means "[[thigh]]", and ''os femoris'' means "the bone within it".
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".

==Intercondylar Fossa==
The intercondylar fossa is present between the condyles at the [[Distal#Proximal_and_distal|distal]] end of the femur. In addition to the intercondylar eminence on the tibial plateau, there is both an anterior and posterior intercondylar fossa (area), the sites of anterior cruciate and posterior cruciate ligament attachment, respectively.
==In other animals==
Parallel structures by the same name exist in other complex animals, such as the bone inside a [[ham (meat)|ham]] or a [[leg of lamb]]. The name femur is also given to the most [[proximal]] full-length jointed segment of an [[arthropod]]'s [[leg]].

For example, the femur of a dog is located at the bottom of the collar bone.
