Determine 1. Femur and Patella. The femur is the single bone from the thigh location. It articulates superiorly With all the hip bone on the hip joint, and inferiorly While using the tibia for the knee joint. The patella only articulates Using the distal finish in the femur.
The pinnacle of your fibula will be the smaller, knob-like, proximal conclusion of your fibula. It articulates Using the inferior facet of the lateral tibial condyle, forming the proximal tibiofibular joint. The skinny shaft with the fibula has the interosseous border from the fibula, a slim ridge working down its medial side to the attachment in the interosseous membrane that spans the fibula and tibia.
The extensor hallucis longus has its origin on the fibula plus the interosseus membrane in between The 2 other extensors and is, equally on the extensor digitorum, is inserted on the last phalanx of big toe ("hallux"). The muscle mass dorsiflexes the hallux, and functions similar to the tibialis anterior in the load-bearing leg.[29] Two muscles about the lateral aspect on the leg sort the fibular (peroneal) group. The fibularis (peroneus) longus and fibularis (peroneus) brevis the two have their origins around the fibula, and they both of those move at the rear of the lateral malleolus in which their tendons move under the fibular retinacula. Underneath the foot, the fibularis longus stretches with the lateral to the medial facet in a groove, thus bracing the transverse arch with the foot. The fibularis brevis is connected around the lateral facet for the tuberosity of the fifth metatarsal. Alongside one another, these two fibularis muscles kind the strongest pronators of the foot.[thirty] The fibularis muscles are highly variable, and a number of other variants can sometimes be existing.[31]
It plantarflexes the hallux and assists in supination. The flexor digitorum longus, eventually, has its origin within the higher A part of the tibia. Its tendon operates to the only real on the foot in which it forks into four terminal tendon connected to the final phalanges in the 4 lateral toes. It crosses the tendon of the tibialis posterior distally within the tibia, and the tendon in the flexor hallucis longus in the only. Distally to its division, the quadratus plantae radiates into it and close to the middle phalanges its tendons penetrate the tendons on the flexor digitorum brevis. Inside the non-pounds-bearing leg, it plantar flexes the toes and foot and supinates. In the burden-bearing leg it supports the plantar arch.[25] (To the popliteus, see above.)
Much more inferiorly, the gluteal tuberosity turns into continual Together with the linea aspera (“tough line”). Here is the roughened ridge that passes distally along the posterior facet on the mid-femur. A number of click here muscles in the hip and thigh regions make lengthy, thin attachments into the femur together the linea aspera.
2a). The menisci have 4 vital functions in the knee: (i) to enhance congruence in between the femur plus the tibia; (ii) to work as shock absorbers as the body bodyweight falls on to your tibial plateau; (iii) to assist in excess weight bearing over the joint; and (iv) to assist lubrication via the circulation of synovial fluid within the knee joint.
There are actually 4 posterior thigh muscles. The biceps femoris has two heads: The lengthy head has its origin around the ischial tuberosity along with the semitendinosus and acts on two joints. The shorter head originates from the center third with the linea aspera around the shaft on the femur along with the lateral intermuscular septum of thigh, and acts on just one joint. Both of these heads unite to variety the biceps which inserts on the head on the fibula. The biceps flexes the knee joint and rotates the flexed leg laterally—it is the only lateral rotator of your knee and so has got to oppose all medial rotator. Additionally, the extensive head extends the hip joint. The semitendinosus and also the semimembranosus share their origin Together with the lengthy head with the biceps, and each attaches over the medial side with the proximal head of the tibia along with the gracilis and sartorius to variety the pes anserinus.
A 1854 English cartoon expressing the Predicament of Victorian women that needed to both drag their hems via soaked or filth, or a little bit raise up their skirts and attract consideration from Males (lots of which have designed an interest in woman knees or ankles at time) In Norse mythology, the race of Jotuns was born in the legs of Ymir.
articulation amongst the head of the fibula as well as inferior element of the lateral condyle in the tibia
The lesser trochanter is a small, bony prominence that lies about the medial element of the femur, just under the neck. An individual, powerful muscle attaches on the lesser trochanter. Running concerning the better and lesser trochanters within the anterior facet from the femur may be the roughened intertrochanteric line. The trochanters can also be connected around the posterior side from the femur by the larger intertrochanteric crest.
The bottom on the fifth metatarsal has a significant, lateral growth that provides for muscle attachments. This expanded foundation on the fifth metatarsal may be felt for a bony bump on the midpoint together the lateral border in the foot. The expanded distal close of every metatarsal is The pinnacle in the metatarsal bone. Each metatarsal bone articulates Along with the proximal phalanx of a toe to sort a metatarsophalangeal joint. The heads of the metatarsal bones also rest on the bottom and form the ball (anterior conclude) of the foot.
Cure typically involves halting the activity that provides knee ache for just a stretch of time, followed by a gradual resumption of action. Good strengthening in the quadriceps femoris muscle mass to right for imbalances is usually vital that you assistance avoid reoccurrence.
lateral, expanded region of your proximal tibia that features the smooth area that articulates Along with the lateral condyle in the femur as part of the knee joint
Like the higher limb, the lower limb is split into three regions. The thigh is usually that part of the lower limb Situated in between the hip joint and knee joint. The leg is specifically the location amongst the knee joint as well as the ankle joint. Distal to the ankle is definitely the foot. The lower limb has 30 bones. They are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. The femur is The one bone on the thigh.
