The stability with the pelvis is furnished by strong ligaments binding the innominate bone into the sacrum anteriorly and posteriorly. The bony pelvis supplies a base for your attachment of muscles in the trunk and also the hip.
Some hip muscles also act either about the knee joint or on vertebral joints. On top of that, because the regions of origin and insertion of many of those muscles are certainly intensive, these muscles are frequently involved in various really unique movements.
The pinnacle on the fibula forms the proximal stop and articulates While using the underside in the lateral condyle with the tibia. The distal fibula articulates with the fibular notch on the tibia. The expanded distal conclusion of the fibula would be the lateral malleolus.
smooth groove Positioned on the anterior aspect with the distal femur, in between the medial and lateral condyles; web site of articulation to the patella
The posterior area finishes distally prior to the popliteal fossa. The anterior and posterior locations from the knee prolong from the proximal areas all the way down to the level on the tuberosity of your tibia. Inside the lower leg the anterior and posterior locations increase down to the malleoli. Behind the malleoli tend to be the lateral and medial retromalleolar locations and powering these could be the region with the heel. Ultimately, the foot is subdivided right into a dorsal location superiorly and a plantar area inferiorly.[forty four]
[six] The thigh is between the hip and knee and would make up the rest of the lower limb.[one] The phrase lower limb or lower extremity is usually utilised to describe most of the leg.
The anterior abdominal muscles conclusion in an aponeurosis and that is thickened inferiorly to type the inguinal ligament, extending with the anterior finish with the iliac crest towards the pubis from the midline. This forms an anatomical Place for the passage of nerves and blood vessels from your trunk into the thigh anteriorly.
These regions articulate While using the medial and lateral condyles from the femur to sort the knee joint. more info Between the articulating surfaces from the tibial condyles will be the intercondylar eminence, an irregular, elevated location that serves since the inferior attachment place for two supporting ligaments with the knee.
articulation between The top from the fibula as well as inferior facet of the lateral condyle of the tibia
The femur is the single bone of the thigh. Its rounded head articulates Together with the acetabulum from the hip bone to kind the hip joint. The pinnacle has the fovea capitis for attachment of the ligament of The pinnacle in the femur. The slender neck joins inferiorly While using the larger and lesser trochanters. Passing between these bony expansions will be the intertrochanteric line on the anterior femur as well as the larger intertrochanteric crest around the posterior femur.
The top with the fibula is definitely the little, knob-like, proximal stop on the fibula. It articulates Along with the inferior element of the lateral tibial condyle, forming the proximal tibiofibular joint. The skinny shaft of your fibula has the interosseous border of the fibula, a slim ridge running down its medial side for your attachment on the interosseous membrane that spans the fibula and tibia.
The posterior muscles of your hip along with the anterior abdominal wall produce these movements (see Chapter 10). Pelvic tilting also occurs in reaction to the tension from the hamstring muscles, which originate within the ischial tuberosities and pass down the posterior facet of the thigh to lower limb supports your knee.
broad groove about the lateral facet of the distal tibia for articulation With all the fibula with the distal tibiofibular joint
The pelvis or pelvic girdle is surely an irregular ring of bone made up of the two innominate bones as well as the sacrum fashioned by five fused vertebrae. Every single innominate bone is built up in the ilium, ischium and pubis, which fuse for the socket for the hip joint. The ilium extends upwards and ends with the iliac crest, that may be felt when placing ‘fingers on hips’.
