The patella may be the kneecap and articulates Using the distal femur. The tibia is definitely the more substantial, bodyweight-bearing bone Found about the medial side with the leg, along with the fibula is the thin bone with the lateral leg. The bones from the foot are divided into a few groups. The posterior percentage of the foot is shaped by a gaggle of seven bones, Each individual of which is named a tarsal bone, While the mid-foot contains five elongated bones, Every of which can be a metatarsal bone. The toes include 14 small bones, Just about every of which is a phalanx bone with the foot.
The distal stop from the femur has medial and lateral bony expansions. About the lateral aspect, The graceful portion that handles the distal and posterior components of the lateral enlargement would be the lateral condyle from the femur. The roughened region about the outer, lateral facet from the condyle would be the lateral epicondyle with the femur. Similarly, the smooth location on the distal and posterior medial femur is definitely the medial condyle with the femur, plus the irregular outer, medial facet of this is the medial epicondyle in the femur. The lateral and medial condyles articulate Together with the tibia to type the knee joint.
Explain the arrangement of the tarsal and metatarsal bones that happen to be associated with both of those the posterior and anterior distribution of overall body bodyweight.
Comparison amongst human and gorilla skeletons. (Gorilla in non-purely natural stretched posture.) Evolution has furnished the human entire body with two unique attributes: the specialization of the higher limb for visually guided manipulation as well as lower limb's development into a system especially adapted for productive bipedal gait.
The anterior 50 percent from the foot is shaped from the 5 metatarsal bones, which are located concerning the tarsal bones of your posterior foot as well as phalanges of your toes (see Determine (PageIndex four )). These elongated bones are numbered 1–5, starting with the medial facet of your foot. The main metatarsal bone is shorter and thicker when compared to the Many others. The next metatarsal will be the longest. The base from the metatarsal bone would be the proximal close of each and every metatarsal bone. website These articulate Along with the cuboid or cuneiform bones.
The narrowed area underneath The top is definitely the neck of the femur. This is a frequent place for fractures from the femur. The increased trochanter is the massive, upward, bony projection Found higher than The bottom of your neck. Various muscles that act through the hip joint connect into the larger trochanter, which, as a result of its projection from your femur, provides extra leverage to these muscles. The greater trochanter can be felt slightly below the pores and skin about the lateral facet within your upper thigh.
Patellofemoral syndrome may very well be initiated by several different triggers, which include unique variations in The form and motion on the patella, a direct blow for the patella, or flat ft or improper shoes that trigger abnormal turning in or out from the ft or leg.
Outline the regions of your lower limb, title the bones present in Every location, and explain the bony landmarks that articulate with each other to form the hip, knee, and ankle joints.
The distal conclusion in the femur has medial and lateral bony expansions. Around the lateral facet, the smooth part that addresses the distal and posterior aspects of the lateral enlargement would be the lateral condyle from the femur. The roughened space to the outer, lateral side of your condyle would be the lateral epicondyle from the femur. In the same way, The sleek location on the distal and posterior medial femur will be the medial condyle with the femur, as well as the irregular outer, medial facet of This is actually the medial epicondyle of the femur. The lateral and medial condyles articulate Along with the tibia to type the knee joint.
The talus bone from the foot gets the burden of the body through the tibia. The talus bone then distributes this pounds toward the ground in two Instructions: a person-half of your body body weight is handed inside a posterior route and a person-half of the weight is passed within an anterior course.
The base in the fifth metatarsal has a sizable, lateral expansion that gives for muscle mass attachments. This expanded foundation with the fifth metatarsal might be felt for a bony bump with the midpoint along the lateral border with the foot. The expanded distal finish of each and every metatarsal is The top of your metatarsal bone. Each individual metatarsal bone articulates Together with the proximal phalanx of website a toe to sort a metatarsophalangeal joint. The heads from the metatarsal bones also relaxation on the ground and type the ball (anterior conclusion) with the foot.
smooth, articulating surface that sorts the distal and posterior sides in the medial expansion from the distal femur
lateral, expanded region of your proximal tibia that features The sleek surface that articulates with the lateral condyle with the femur as Section of the knee joint
Lower leg accidents are frequent though working or participating in sports activities. About 10% of all accidents in athletes involve the lower extremities.[fifty seven] Nearly all athletes sprain their ankles; this is especially brought on by the enhanced hundreds onto the ft every time they transfer in the foot down or within an outer ankle position.
