NPCC-Lower Limb
lower limb question
| Question | Answer |
|---|---|
| Number of bones in the foot | 26 |
| The location of the tuberosity that is a common fracture site of the foot | base of the fifth metatarsal |
| Name the joints of the metatarsals | metatarsophalangeal joint (MTP), tarsometatarsal joint (TMT) |
| Where are the sesamoid bones located on in the foot? | plantar surface at the head of the first metatarsal |
| Name the 7 metatarsals with their alternate names | Talus (astragulus), Calcaneus (Os Calcis), Cuboid, Navicular (Scaphoid), lateral, medial and intermediate cuneiforms (1,2,3) |
| The most posterior-inferior part of the calcaneus | tuberosity |
| Rounded processes on the calcaneus | lateral and medial processes |
| A ridge of bone on the superior portion of the calcaneus (visualized laterally on an axial projection) | peroneal trochlea or trochlear process |
| Large prominent bony process on the medial aspect of the calcaneus | sustentaculum tali |
| Which two bones does the calcaneus articulate? | cuboid and talus |
| The calcaneus articulates with the talus superiorly to form what joint? | subtalar joint or talocalcaneal |
| The 3 articular facets at the talus joint | posterior, anterior and middle articular facets |
| The opening in the middle of the subtalar joint | sinus tarsi or tarsal sinus |
| The four bones that articulates with the talus | tibia, fibula, calcaneus and navicular |
| Which cuneiform is the smallest? the largest? | smallest-intermediate; largest-medial |
| The 4 bones that the medial cuneiform articulate | navicular, first and second metatarsal, intermediate cuneiform |
| The 4 bones the the intermediate cuneiform articulate with | navicular, medial and lateral cuneiforms and second metatarsal |
| The 6 bones that the lateral cuneiform articulate | navicular, second, third, fourth metatarsals, intermediate cuneiform, cuboid |
| The 4 bones that the cuboid articulate | calcaneus, lateral cuneiform, fourth and fifth metatarsal |
| Name the two arches of the foot | longitudinal and transverse |
| The 3 bones of the ankle joint | tibia, fibula and talus |
| The expanded distal end of the fibula extending down the lateral side of the talus | lateral malleolus |
| The medial elongated process of the distal tibia and extending alongside the medial talus | medial malleolus |
| the deep, three-sided socket formed by the tibia, fibula and talus | mortise |
| The expanded process at the distal anterior and lateral tibia | anterior tubercle |
| Distal tibial joint surface forming the roof of the ankle mortise joint | tibial plafond |
| joint-type of the ankle | synovial; ginglymus-hinge |
| Joint movements of the ankle | flexion and extension (dorsiflexion and plantar flexion) |
| The weight-bearing bone of the lower leg | tibia |
| 3 parts of the tibia | body (shaft), distal extremity, proximal extremity |
| Two large processes making up the medial and lateral aspects of the proximal tibia | medial and lateral condyles |
| The two, small pointed processes on the superior surface of the tibia | intercondylar eminence |
| The names of the two pointy processes at the intercondylar eminence | lateral and medial tubercles |
| The two smooth, concave articular facets on the upper articular surface of the tibia | tibial plateau |
| What does the tibial plateau articulate with? | femur |
| Rough-textured prominence located on the midanterior surface of the proximal tibia | tibial tuberosity |
| Sharp ridge along the anterior surface of the tibia | anterior crest or border (shin) |
| Short pyramid process on the distal end of the tibia | medial malleolus |
| The lateral aspect of the tibia forms a flattened, triangular shaped structure called... | fibular notch |
| What bones does the fibula articulate? | the tibia proximally and the tibia and talus distally |
| The head of the fibula is distal or proximal | proximal |
| The extreme proximal end of the fibula that is pointed is called the... | Apex |
| The 5 parts of the fibula | apex, head, neck, body and lateral malleolus |
| The longest and strongest bone in the entire body | femur |
| The smooth, triangular-shaped, shallow surface at the distal portion of the anterior femur | patellar surface (intercondylar sulucus; trochlear groove) |
| What joints make up the ankle mortise? | talofibular, tibiotalar |
| What joints make up the knee? | patellofemoral, femorotibial |
| The notch between the large, rounded condyles on the distal femur | intercondylar fossa |
| The deep depression between posterior and middle articular facets of the calcaneus | calcaneal sulcus |
