Q. The talus bone of your foot receives the burden of the body from the tibia. The talus bone then distributes this weight towards the ground in two directions: a single-fifty percent of the body weight is handed in a very posterior course and one particular-fifty percent of the weight is passed within an anterior direction.
The large toe has two phalanx bones, the proximal and distal phalanges. The remaining toes all have proximal, middle, and distal phalanges. A joint in between adjacent phalanx bones is called an interphalangeal joint.
tiny, knob-like, proximal conclude with the fibula; articulates Using the inferior facet of the lateral condyle on the tibia
Comparison amongst human and gorilla skeletons. (Gorilla in non-pure stretched posture.) Evolution has furnished the human human body with two unique options: the specialization with the higher limb for visually guided manipulation and also the lower limb's advancement into a mechanism particularly tailored for efficient bipedal gait.
The posterior tibial types a direct continuation in the popliteal artery which enters the flexor compartment on the lower leg to descend guiding the medial malleolus the place it divides in the medial and lateral plantar arteries, of which the posterior department presents increase to the fibular artery.[43]
The tibial tuberosity is really an elevated spot within the anterior aspect on the tibia, around its proximal conclude. It is the last internet site of attachment for that muscle tendon affiliated with the patella. A lot more inferiorly, the shaft of the tibia turns into triangular in form. The anterior apex of
Consider the illustrations of the pelvis in Appendix I. Use an articulated skeleton to discover: the sacrum on the vertebral column; the two innominate bones that meet from the midline; and also the socket (acetabulum) for The pinnacle in the femur. Trace how the human body excess weight is transferred with the vertebral column for the femur by way of the pelvis.
The pinnacle with the fibula sorts the proximal conclusion and articulates With all the underside from the lateral condyle in the tibia. The distal fibula articulates With all the fibular notch in the tibia. The expanded distal stop with the fibula is definitely the lateral malleolus.
The distal end from the femur has medial and lateral bony expansions. Over the lateral side, lower limb supports the smooth portion that addresses the distal and posterior areas of the lateral enlargement is the lateral condyle in the femur. The roughened spot to the outer, lateral facet of your condyle is the lateral epicondyle from the femur. Likewise, The sleek area in the distal and posterior medial femur would be the medial condyle with the femur, plus the irregular outer, medial facet of Here is the medial epicondyle of your femur. The lateral and medial condyles articulate with the tibia to form the knee joint.
The artery enters the thigh given that the femoral artery which descends the medial facet on the thigh towards the adductor canal. The canal passes through the anterior for the posterior side with the limb the place the artery leaves with the adductor hiatus and becomes the popliteal artery.
The fibula will be the slender bone located on the lateral facet from the leg (see [url]). The fibula would not bear body weight. It serves mostly for muscle attachments and thus is basically surrounded by muscles. Only the proximal and distal finishes of the fibula is often palpated.
most medial of your three cuneiform tarsal bones; articulates posteriorly With all the navicular bone, laterally Along with the intermediate cuneiform bone, and anteriorly with the main and second metatarsal bones
most lateral from the a few cuneiform tarsal bones; articulates posteriorly With all the read more navicular bone, medially While using the intermediate cuneiform bone, laterally Together with the cuboid bone, and anteriorly with the third metatarsal bone
The abductor hallucis stretches together the medial edge of the foot, from the calcaneus to The bottom of the very first phalanx of the main digit along with the medial sesamoid bone. It's an abductor along with a weak flexor, and likewise aids manage the arch on the foot. Lateral to the abductor hallucis would be the flexor hallucis brevis, which originates in the medial cuneiform bone and with the tendon from the tibialis posterior. The flexor hallucis provides a medial along with a lateral head inserted laterally to your abductor hallucis.
