rounded, proximal conclusion in the femur that articulates with the acetabulum on the hip bone to variety the hip joint
irregular elevation about the top-quality end from the tibia, among the articulating surfaces on the medial and lateral condyles
The segments are linked by joints, the hip, knee, ankle and joints of your foot, that may alter to your improvements that arise in the line of weight in the limbs as The pinnacle and trunk transfer previously mentioned. The muscles across the joints counteract the effects of gravity and any exterior forces that disturb the stability of the body.
sleek groove Positioned about the anterior side of the distal femur, concerning the medial and lateral condyles; web-site of articulation to the patella
medial, expanded location with the proximal tibia that features the smooth floor that articulates Along with the medial condyle with the femur as Component of the knee joint
The lumbar plexus is shaped lateral to the intervertebral foramina because of the ventral rami of the initial 4 lumbar spinal nerves (L1-L4), which all go through psoas significant. The larger sized branches in the plexus exit the muscle to move sharply downward to reach the abdominal wall along with the thigh (under the inguinal ligament); aside from the obturator nerve which pass through the lesser pelvis to get to the medial Portion of the thigh in the obturator foramen.
The patella (kneecap) is largest sesamoid bone of the body (see [website link]). A sesamoid bone is usually a bone that is certainly included to the tendon of the muscle where by that tendon crosses a joint. The sesamoid bone articulates Together with the fundamental bones to avoid harm to the muscle tendon resulting from rubbing towards the bones through movements from the joint. The patella is found in the tendon of the quadriceps femoris muscle mass, the big muscle mass of your anterior thigh that passes across the anterior knee to attach on the tibia.
A 1854 English cartoon expressing the Problem of Victorian Ladies that needed to both drag their hems via soaked or filth, or a little bit elevate up their skirts and draw in focus from Males (most of which have developed an fascination in feminine knees or ankles at the time) In Norse mythology, the race of Jotuns was born within the legs of Ymir.
The patella articulates Together with the patellar surface area from the femur and thus helps prevent rubbing with the muscle tendon towards the more info distal femur. The patella also lifts the tendon away from the knee joint, which improves the leverage electric power in the quadriceps femoris muscle mainly because it functions across the knee. The patella doesn't articulate with the tibia.
A leg is taken into account straight when, With all the feet introduced collectively, both the medial malleoli of your ankle along with the medial condyles from the knee are touching. Divergence from the traditional femorotibial angle is termed genu varum if the center in the knee joint is lateral towards the mechanical axis (intermalleolar length exceeds 3 cm), and genu valgum whether it is medial for the mechanical axis (intercondylar length exceeds 5 cm). These conditions impose unbalanced masses on the joints and stretching of both the thigh's adductors and abductors.[12]
Consider the illustrations on the tibia, fibula as well as the bones in the foot viewed in medial and lateral watch in Appendix I.
roughened location about the posterior aspect with the proximal femur, extending inferiorly with the foundation of your higher trochanter
The large expansion discovered around the medial side from the distal tibia may be the medial malleolus (“minor hammer”). This kinds the big bony bump located about the medial aspect in the ankle area. The two The sleek floor on the inside of your medial malleolus and The sleek spot in the distal close on the tibia articulate Using the talus bone of your foot as Section of the ankle joint.
On the anterior thigh muscles the largest would be the 4 muscles in the quadriceps femoris: the central rectus femoris, which is surrounded via the 3 vasti, the vastus intermedius, medialis, and lateralis. Rectus femoris is attached to your pelvis with two tendons, although the vasti are inserted to the femur. All 4 muscles unite in website a common tendon inserted into your patella from the place the patellar ligament extends it right down to the tibial tuberosity. Fibers from the medial and lateral vasti variety two retinacula that stretch past the patella on both sides down to the condyles of your tibia.
