Determine one. Femur and Patella. The femur is the single bone in the thigh region. It articulates superiorly with the hip bone in the hip joint, and inferiorly Using the tibia with the knee joint. The patella only articulates with the distal stop of the femur.
The pinnacle from the fibula will be the smaller, knob-like, proximal finish of the fibula. It articulates While using the inferior facet of the lateral tibial condyle, forming the proximal tibiofibular joint. The thin shaft on the fibula has the interosseous border in the fibula, a slim ridge managing down its medial facet for the attachment with the interosseous membrane that spans the fibula and tibia.
The lower limb is divided into a few locations. These are typically the thigh, Positioned involving the hip and knee joints; the leg, Found among the knee and ankle joints; and distal into the ankle, the foot.
Comparison amongst human and gorilla skeletons. (Gorilla in non-organic stretched posture.) Evolution has offered the human body with two unique features: the specialization on the higher limb for visually guided manipulation and also the lower limb's progress into a mechanism specially tailored for effective bipedal gait.
The stretching of such ligaments suppliers energy within the foot, instead of passing these forces in to the leg. Contraction from the foot muscles also plays a crucial part On this Vitality absorption. When the load is taken out, the elastic ligaments recoil and pull the ends from the arches closer together. This Restoration from the arches releases the stored Power and improves the energy performance of going for walks.
The patella (kneecap) is premier sesamoid bone of the body (see Determine (PageIndex 1 )). A sesamoid bone is usually a bone which is included into the tendon of the muscle where by that tendon crosses a joint. The sesamoid bone articulates Using the underlying bones to stop damage to the muscle mass tendon on account of rubbing towards the bones during movements from the joint. The patella is present in the tendon in the quadriceps femoris muscle mass, the big muscle in the anterior thigh that passes over the anterior knee to attach on the tibia.
The fovea capitis is actually a slight indentation to the medial facet with the femoral head that serves as the site of attachment for your ligament of the head in the femur. This ligament spans the femur and acetabulum, but is weak and supplies very little help for that hip joint. It does, having said that, have an important artery that supplies The pinnacle of the femur.
Define the areas on the lower limb, title the bones located in Each individual region, and describe the bony landmarks that articulate with each other to kind the hip, knee, and website ankle joints.
The 5 metatarsal bones kind the anterior foot. The bottom of those bones articulate With all the cuboid or cuneiform bones. The metatarsal heads, at their distal finishes, articulate While using the proximal phalanges from the toes.
The proximal group of tarsal bones includes the calcaneus and talus bones, the navicular bone is intermediate, along with the distal team contains the cuboid bone as well as the medial, intermediate, and lateral cuneiform bones.
Functionally, the muscles in the leg are either extensors, accountable for the dorsiflexion of the foot, or flexors, responsible for the plantar flexion. These muscles may categorised by innervation, muscles equipped via the anterior subdivision of your plexus and people provided with the posterior subdivision.[27] The leg muscles acting within the foot are called the extrinsic foot muscles whilst the foot muscles situated in the foot are referred to as intrinsic.[28]
The hardware attaches straight to current new fashion quickie frames, and buyers can decide on the pad dimension and facet of assist. It is vital to include the serial amount of the chair at checkout to make certain good in shape.
most lateral in the three cuneiform tarsal bones; articulates posteriorly While using the navicular bone, medially Together with the intermediate cuneiform bone, laterally With all the cuboid bone, and anteriorly with the 3rd metatarsal bone
The abductor hallucis stretches along the medial fringe of the foot, in the calcaneus to The bottom of the initial phalanx of the first digit plus the medial sesamoid bone. It really is an abductor in addition to a weak flexor, and in addition helps retain the arch from the foot. Lateral to your abductor hallucis may be the flexor hallucis brevis, which originates within the medial cuneiform bone and from your tendon of your tibialis posterior. The flexor hallucis includes a medial in addition to a lateral head inserted laterally towards the abductor hallucis.
