Question

Which lower extremity bones participate in joints?

Answer 1

The lower extremity bones that participate in joints include:

Femur: The femur is the thigh bone and is the longest bone in the human body. It participates in the hip joint at its proximal end.

Patella: The patella, commonly known as the kneecap, is a small, flat, triangular bone located in front of the knee joint. It articulates with the femur and forms part of the knee joint.

Tibia: The tibia, or shinbone, is the larger and stronger of the two lower leg bones. It is located on the medial side of the leg and forms the knee joint with the femur at its proximal end. It also forms the ankle joint with the talus bone at its distal end.

Fibula: The fibula is the slender bone located on the lateral side of the lower leg. It runs parallel to the tibia and does not bear as much weight. The fibula contributes to the stability of the ankle joint and provides attachment points for muscles.

Tarsal Bones: The tarsal bones are a group of seven bones that form the posterior half of the foot. These bones, including the calcaneus (heel bone), talus, navicular, cuboid, and three cuneiform bones, articulate with each other to form the various joints of the foot.

Metatarsal Bones: The metatarsal bones are the long bones of the foot, and there are five of them. They connect the tarsal bones to the phalanges (toe bones) and form the metatarsophalangeal joints.

Phalanges: The phalanges are the bones of the toes. Each toe has three phalanges (except for the big toe, which has two), and they articulate to form the interphalangeal joints.

These bones work together in various combinations to allow for the movement and support of the lower extremities.

Answer 2

The bones of the lower limb that participate in joints include the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges.

Step-by-step explanation:

The bones of the lower limb that participate in joints include the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. These bones are essential for supporting the entire weight of the body and enabling movement in the lower extremities.
