Magnus is a strong adductor, especially active when crossing legs. Its top-quality section is really a lateral rotator however the inferior portion acts like a medial rotator on the flexed leg when rotated outward and in addition extends the hip joint. The adductor minimus can be an incompletely divided subdivision with the adductor magnus. Its origin sorts an anterior part of the magnus and distally it really is inserted to the linea aspera higher than the magnus. It functions to adduct and lateral rotate the femur.[21]
The distal conclude in the femur has medial and lateral bony expansions. On the lateral side, The sleek part that handles the distal and posterior aspects of the lateral enlargement is the lateral condyle on the femur. The roughened spot about the outer, lateral side from the condyle will be the lateral epicondyle of the femur. Equally, The graceful region in the distal and posterior medial femur is the medial condyle with the femur, and also the irregular outer, medial facet of This can be the medial epicondyle of the femur. The lateral and medial condyles articulate With all the tibia to sort the knee joint.
little, knob-like, proximal stop from the fibula; articulates Along with the inferior aspect of the lateral condyle of your tibia
articulation concerning The pinnacle of the fibula and the inferior aspect of the lateral condyle in the tibia
Additional inferiorly, the gluteal tuberosity turns into continual Together with the linea aspera (“rough line”). This is the roughened ridge that passes distally together the posterior side with the mid-femur. Many muscles in the hip and thigh locations make extended, slender attachments for the femur together the linea aspera.
The tibial tuberosity is an elevated place around the anterior side with the tibia, near its proximal finish. It is the last web-site of attachment for the muscle tendon associated with the patella. Much more inferiorly, the shaft in the tibia gets triangular in form. The anterior apex of
The opponens digiti minimi originates through the extended plantar ligament as well as the plantar tendinous sheath from the fibularis (peroneus) longus which is inserted within the fifth metatarsal. When present, it functions to plantar flex the fifth digit and supports the plantar arch. The flexor digiti minimi arises in the region of foundation of your fifth metatarsal which is inserted on to the base of the 1st phalanx with the fifth digit where by it is usually merged Using the abductor of the initial digit.
(plural = phalanges) one of several 14 bones that sort the toes; these consist of the proximal and distal phalanges of the massive toe, and also the proximal, Center, and distal phalanx bones of toes two via 5
articulation concerning The pinnacle on the fibula along with the inferior aspect of the lateral condyle of the tibia
The femur is the single bone on the thigh. Its rounded head articulates While using the acetabulum of the hip bone to kind the hip joint. The top has the fovea capitis for attachment with the ligament of The pinnacle of the femur. The slender neck joins inferiorly Along with the bigger and lesser trochanters. Passing between these bony expansions would be the intertrochanteric line within the anterior femur and also the greater intertrochanteric crest about the posterior femur.
Think about the illustrations of your tibia, fibula and the bones from the foot noticed in medial and lateral check out in Appendix I.
Extension is definitely website the return movement from flexion and carries on outside of the anatomical posture to place the foot driving the human body. Extension raises the human body from sitting down to standing, and up on into the step above in climbing stairs.
Generally, the massive joints from the lower limb are aligned in the straight line, which signifies the mechanical longitudinal axis from the leg, the Mikulicz line. This line stretches from your hip joint (or maybe more precisely The top with the femur), through the knee joint (the intercondylar eminence in the tibia), and all the way down to the middle from the ankle (the ankle website mortise, the fork-like grip amongst the medial and lateral malleoli). During the tibial shaft, the mechanical and anatomical axes coincide, but inside the femoral shaft they diverge six°, leading to the femorotibial angle of 174° inside of a leg with regular axial alignment.
The patella (kneecap) is largest sesamoid bone of the body (see Figure 1). A sesamoid bone is a bone that's incorporated in to the tendon of a muscle where that tendon crosses a joint. The sesamoid bone articulates Using the underlying bones to prevent harm to the muscle mass tendon resulting from rubbing from the bones through actions in the joint. The patella is found in the tendon from the quadriceps femoris muscle, the massive muscle mass in the anterior thigh that passes throughout the anterior knee to attach into the tibia.
