Q. The talus bone with the foot receives the weight of your body from your tibia. The talus bone then distributes this weight towards the ground in two Instructions: one particular-fifty percent of the human body fat is passed in a very posterior path and 1-half of the burden is passed within an anterior way.
The interosseous border of every bone may be the attachment web site for the interosseous membrane of your leg, the connective tissue sheet that unites the tibia and fibula.
About the dorsal aspect, two prolonged extrinsic extensor muscles are superficial to your intrinsic muscles, as well as their tendons kind the dorsal aponeurosis of your toes. The brief intrinsic extensors as well as the plantar and dorsal interossei radiates into these aponeuroses.
The lower limbs would be the supporting pillars whenever we stand. A pillar must have power and ought to not collapse less than the weight previously mentioned. The bones, joints and muscles alongside one another convert the lower limb into a secure assistance that is connected to the trunk because of the pelvic girdle. The pillar is split into segments, the thigh, leg and foot.
The posterior area finishes distally prior to the popliteal fossa. The anterior and posterior regions with the knee lengthen from the proximal areas down to the extent from the tuberosity with the tibia. Inside the lower leg the anterior and posterior locations lengthen all the way down to the malleoli. Guiding the malleoli will be the lateral and medial retromalleolar areas and guiding these would be the location from the heel. Last but not least, the foot is subdivided into a dorsal region superiorly as well as a plantar area inferiorly.[forty four]
lateral, expanded region with the proximal tibia that features The sleek surface that articulates Together with the lateral condyle of your femur as part of the knee joint
Twisting injuries from the knee may possibly occur in Activity, especially soccer. The subsequent hurt may perhaps happen:
The elongated shaft in the femur incorporates a slight anterior bowing or curvature. At its proximal conclude, the posterior shaft has the gluteal tuberosity, a roughened spot extending inferiorly through the increased trochanter.
The femur is The one bone in the thigh. Its rounded head articulates Using the acetabulum with the hip bone to kind the hip joint. The pinnacle has the fovea capitis for attachment of the ligament of The pinnacle from the femur. The slender neck joins inferiorly With all the increased and lesser trochanters. Passing amongst these bony expansions are classified as the intertrochanteric line about the anterior femur as well as more substantial intertrochanteric crest within the posterior femur.
View this video clip to look at how a fracture with the mid-femur is surgically fixed. How are The 2 parts of the broken femur stabilized throughout surgical mend of the fractured femur?
These muscles as well as their fatty tissue functionality as cushions that transmit the weight of your body downward. In general, the foot can be a useful entity.[34]
If stretching on the ligaments is prolonged, abnormal, or repeated, it may result in a gradual lengthening on the supporting ligaments, with subsequent depression or collapse on the longitudinal arches, especially over the medial aspect of your foot. This issue is called pes planus (“flat foot” or “fallen arches”).
These bones would be the medial cuneiform, the intermediate cuneiform, and also the lateral cuneiform. Each of such bones provides a wide outstanding surface area and read more a slender inferior floor, which jointly develop the transverse (medial-lateral) curvature on the foot. The navicular and lateral cuneiform bones also articulate Together with the medial aspect in the cuboid bone.
The abductor hallucis stretches alongside the medial edge of the foot, from the calcaneus to The bottom of the main phalanx of the 1st digit along with the medial sesamoid bone. It really is an abductor and a weak flexor, in addition to will help preserve the arch of your foot. Lateral to your abductor hallucis may be the flexor hallucis brevis, which originates from the medial cuneiform bone and with the tendon from the tibialis posterior. The flexor hallucis contains a medial plus a lateral head inserted laterally to the abductor hallucis.
