Determine 1. Femur and Patella. The femur is The only bone of your thigh location. It articulates superiorly with the hip bone for the hip joint, and inferiorly with the tibia for the knee joint. The patella only articulates While using the distal close of the femur.
short, distinguished ridge running among the increased and lesser trochanters to the posterior side from the proximal femur
The head in the fibula types the proximal conclude and articulates with the underside of the lateral condyle from the tibia. The distal fibula articulates Along with the fibular notch from the tibia. The expanded distal finish with the fibula is the lateral malleolus.
The medial ligament is most often torn, and in serious circumstances the anterior cruciate ligament is involved as being the tibia rotates laterally. Significantly less usually, the lateral ligament is torn, along with the posterior cruciate ligament tears in the event the tibia is forced backwards in relation on the femur.
A. The lower limb is divided into 3 areas. The thigh would be the area Positioned involving the hip and knee joints. It has the femur as well as patella. The hip joint is fashioned via the articulation concerning the acetabulum of your hip bone and The pinnacle of your femur. The leg is definitely the location concerning the knee and ankle joints, and has the tibia (medially) and the fibula (laterally). The knee joint is formed with the articulations involving the medial and lateral condyles of your femur, as well as medial and lateral condyles of your tibia. Also affiliated with the knee is definitely the patella, which articulates Along with the patellar floor in the distal femur.
It is felt as a uninteresting, aching agony round the front in the knee and deep towards the patella. The pain may be felt when going for walks or jogging, heading up or down stairs, kneeling or squatting, or following sitting down While using the knee bent for an prolonged time period.
You will find four posterior thigh muscles. The biceps femoris has two heads: The lengthy head has its origin within the ischial tuberosity together with the semitendinosus and acts on two joints. The quick head originates from the middle third from the linea aspera click here around the shaft from the femur and also the lateral intermuscular septum of thigh, and acts on just one joint. Both of these heads unite to sort the biceps which inserts on The top on the fibula. The biceps flexes the knee joint and rotates the flexed leg laterally—it is the only lateral rotator on the knee and so has got to oppose all medial rotator. Additionally, the lengthy head extends the hip joint. The semitendinosus along with the semimembranosus share their origin While using the very long head on the biceps, and the two attaches around the medial side with the proximal head on the tibia together with the gracilis and sartorius to form the pes anserinus.
The prospect of damaging our lower extremities will probably be minimized by having information about some functions associated with lower leg injuries and producing an accurate type of managing, which include not over-pronating the foot or overusing the legs.
The patella articulates Using the patellar surface area of your femur and thus helps prevent rubbing from the muscle mass tendon against the distal femur. The patella also lifts the tendon faraway from the knee joint, which increases the leverage electric power of the quadriceps femoris muscle mass mainly because it acts over the knee. The patella does not articulate Together with the tibia.
The femur is The one bone in the thigh. Its rounded head articulates Using the acetabulum of your hip bone to kind the hip joint. The head has the fovea capitis for attachment with the ligament of the head of your femur. The slim neck joins inferiorly with the larger and lesser trochanters. Passing among these bony expansions are the intertrochanteric line to the anterior femur and also the larger sized intertrochanteric crest around the posterior femur.
The head of the fibula may be the smaller, knob-like, proximal end from the fibula. It articulates Together with the inferior facet of the lateral tibial condyle, forming the proximal tibiofibular joint. The skinny shaft on the fibula has the interosseous border with the fibula, a slender ridge functioning down its medial facet with the attachment of your interosseous membrane that spans the fibula and tibia.
Extension may be the return movement from flexion and continues past the anatomical place to place the foot behind the human body. Extension raises the human body from sitting down to standing, and up on on the move higher than in climbing stairs.
The proximal tibia consists of the expanded medial and lateral condyles, which articulate Along with the medial and lateral condyles from the femur to variety the knee joint. Among the tibial condyles will be the intercondylar eminence. To the anterior side of the proximal tibia could be the tibial tuberosity, that is ongoing inferiorly Using the anterior border on the tibia.
Posteriorly, this assist is supplied by the calcaneus bone read more and anteriorly with the heads (distal ends) in the metatarsal bones. The talus bone, which receives the weight of the body, is located at the best of your longitudinal arches. Overall body body weight is then conveyed with the talus to the bottom through the anterior and posterior ends of click here these arches.
