Femur and Patella Flashcards
Femur
Location: The thigh
function: largest and longest bone of the skeleton
Head of the Femur
Capped with hyaline cartilages
Function: articulates with the acetabulum of the pevlis
Fovea Capitis
Location: medial side of the head is a small pit
Function: attachment of the round ligamentum teres
Ligamentum Teres
Function: helps to anchor the head of the femur in the acetabulum.
Anatomical Neck
Location: after the head, the femur narrows
Function: does not lie in a straight line with the diaphysis, but at an angle that ranges from 120 degrees to 140 degrees.
Greater Trochanter
Location: found on the superior/ lateral side,
Lesser Trochanter
Location: seen on the inferior/ medial surface
Greater and Lesser Trochanter (function)
Serve to attach powerful hip muscles
Intertrochanteric crest
Locaion: situated btwn the trochanter on the posterior surface and descending at a steep angle
Linea Aspera
Rough line
Location: posterior surface of the diaphysis
Running vertically in the middle third of the femur
Function: attachment of powerful thigh adductor muscles
Medial Lateral Condyles (Location)
Distal end of the femur, expanded portion of the diaphysis
Function: articulates with the tibia, forming the synovial hinge joint of the knee.
Intercondylar Fossa
Location: deep notch btwn the condyles on the posterior surface
Adductor Tubercle
Location: located above the medial condye
Function: attachment of the powerful adductor magnus muscle
Popliteal Fossa
Location: diamond shaped region located behind the knee, Bordered on each side by the hamstrong and calf muscles
Function: contains arteries, veins, nerves, lymphatic vessels and collection of lymph nodes that are mebedded in aprotective bed of adipose tissue.
Patella Surface
Location: anterior surface of the distal femur
Function: covered with hyaline cartilage for the articulation with the patella
