joint Positioned in the proximal conclusion in the lower limb; formed by the articulation between the acetabulum of the hip bone and The pinnacle of your femur
The sensory and motor innervation towards the lower limb is equipped by the lumbosacral plexus, and that is formed via the ventral rami in the lumbar and sacral spinal nerves with additional contributions with the subcostal nerve (T12) and coccygeal nerve (Co1).
Propulsion muscles exert forces on the bottom to propel your body horizontally or upwards in walking, jumping or climbing stairs.
The posterior foot is fashioned through the seven tarsal bones. The talus articulates superiorly While using the distal tibia, the medial malleolus with the tibia, as well as the lateral malleolus of your fibula to kind the ankle joint.
The leg contains the massive tibia around the medial facet as well as the slender fibula on the lateral aspect. The tibia bears the weight of your body, whereas the fibula isn't going to bear weight.
The lower limb is divided into a few regions. The thigh is definitely the location Situated in between the hip and knee joints. It has the femur along with the patella. The hip joint is shaped by the articulation between the acetabulum of your hip bone and The pinnacle in the femur. The leg may be the region between the knee and ankle joints, and has the tibia (medially) along with the fibula (laterally). The knee joint is formed by the articulations involving the medial and lateral condyles on the femur, and also the medial and lateral condyles on the tibia. Also linked to the knee may be the patella, which articulates with the patellar area in the distal femur.
The five metatarsal bones form the anterior foot. The base of those bones articulate While using the cuboid or cuneiform bones. The metatarsal heads, at their distal ends, articulate Together with the proximal phalanges of your toes.
The foot is uncovered distal towards the ankle and has 26 bones. The ankle joint is formed through the articulations amongst the talus bone with the foot plus the distal close of your tibia, the medial malleolus of the tibia, and the lateral malleolus of the fibula. The posterior foot consists of the seven tarsal bones, that are the talus, calcaneus, navicular, cuboid, and also the medial, intermediate, and lateral cuneiform bones. The anterior foot includes the five metatarsal bones, which happen to be numbered one–five starting off to the medial aspect on the foot. The toes consist of 14 read more phalanx bones, with the major toe (toe #1) getting a proximal along with a distal phalanx, and another toes getting proximal, Center, and distal phalanges.
tarsal bone that articulates superiorly Using the tibia and fibula in the ankle joint; also articulates inferiorly Using the calcaneus bone and anteriorly with the navicular bone
The anterior ligament from the hip joint, the iliofemoral ligament (Figure 8.one ) is essential in resisting the inclination for the trunk to drop backwards to the lower limbs when the line of your body body weight falls behind the hip joint.
The base from the fifth metatarsal has a sizable, lateral expansion that provides for muscle mass attachments. This expanded foundation from the fifth metatarsal might be felt as a bony bump on the midpoint together the lateral border of the foot. The expanded distal stop of each and every metatarsal is The more info pinnacle of your metatarsal bone. Each individual metatarsal bone articulates Along with the proximal phalanx of a toe to variety a metatarsophalangeal joint. The heads of your metatarsal bones also relaxation on the bottom and sort the ball (anterior finish) with the foot.
Leaping – is an additional hazard because When the legs usually do not land properly following an initial leap, there may be damage to the meniscus inside the knees, sprain for the ankle by everting or inverting the foot, or damage to the Achilles tendon and gastrocnemius if there is an excessive amount of pressure even though plantar flexing.[58]
wide groove to the lateral side on the distal tibia for articulation Using the fibula for the distal tibiofibular joint
tarsal bone that articulates posteriorly Together with the talus bone, laterally with the cuboid bone, and anteriorly With all the medial, intermediate, and lateral cuneiform bones
