Study Notes
Lower Extremity Terms
- Tibiofibular: Refers to the two joints located in the lower leg, specifically between the tibia and fibula.
- Intercondylar fossa: A depression located between the femoral condyles, found on the posterior aspect of the femur.
- Greater trochanter: An elevation on the femur, positioned superiorly and laterally, serving as a muscle attachment site.
Bones and Joint Structures
- Lateral: Describes the position of the fibula, which is the smaller bone of the lower leg, located on the outside.
- Metatarsal: The five long bones in the forefoot that connect the tarsal bones to the toes.
- Patella: A sesamoid bone that functions to protect the knee joint and assist with knee extension.
Key Leg Bones
- Tibia: The larger, medial bone of the lower leg, responsible for bearing weight.
- Mortise: Another term for the ankle joint, referring to the joint formed by the tibia and fibula as they connect to the talus.
- Cuboid: A lateral tarsal bone located on the outer side of the foot, playing a role in foot stability.
Toe and Tarsal Bones
- Phalanges: The bones that make up the toes, each toe typically consisting of three phalanges (except the big toe which has two).
- Navicular: A tarsal bone situated between the talus and the cuneiforms, aiding in foot structure.
- Femur: The longest and strongest bone in the lower extremity, extending from the hip to the knee.
Additional Bone Features
- Malleolus: The bony projections found at the distal ends of the tibia (medial malleolus) and fibula (lateral malleolus), forming part of the ankle.
- Menisci: C-shaped cartilage pads located between the tibia and femur in the knee joint that act as cushions and help stabilize the joint.
- Condyles: Rounded ends of the tibia that articulate with the femur at the knee, allowing for movement and support.
Tarsal Bones
- Calcaneus: The largest tarsal bone, also known as the heel bone, providing support while standing and walking.
- Talus: The most superior tarsal bone, crucial for ankle joint movement and articulating with the tibia.
- Plateaus: Flat, articular surfaces located on the superior end of the tibia that articulate with the femur at the knee joint.
