Kinesiology Flashcards
Muscles which plantarflex the ankle
Gastrocnemius, soleus, assistance from fibularis longus.
Muscles which dorsiflex the foot
Tibialis anterior and extensor digitorum longus.
Muscles which invert the foot
Tibialis anterior
Muscles which evert the foot
Fibularis longus, extensor digitorum longus.
Pelvic bones
Ilium, ischium, pubis
Ilium
Superior portion of the pelvic bone. A large bowl.
Ischium
Inferior posterior portion of the pelvic bones.
Pubis
Inferior, anterior portion of the pelvic bone.
Acetabulum
Socket of the hip joint.
Acetabulofemoral joint
Hip joint.
Bony landmarks of the femur
Condyles, epicondyles, adductor tubercle, greater trochanter.
Femoral condyles
Form the upper portion of the knee joint.
Femoral epicondyles
Sit proximal to the condyles and serve as muscular attachment sites.
Adductor tubercle
Bony prominence which sits proximal to the medial femoral epicondyle. Acts as an attachment site for the adductors.
Greater trochanter
Muscular attachment point on the proximal, lateral portion of the femur.
Medial and lateral meniscus
Fibrocartilage discs inside the knee joint at the proximal end of the tibia.
ACL and PCL
Ligaments inside the knee which prevent forward and backward movement of the tibia in relation to the femur.
ACL and PCL stand for…
Anterior cruciate ligament posterior cruciate ligament
TCL and FCL
Ligaments found of the sides of the knee which prevent side to side motion.
TCL and FCL stand for…
Tibial collateral ligament and fibular collateral ligament.
Patellar ligament
Ligament which connects the patella to the tibial tuberosity.
Infrapatellar fat pad
Fat pad beneath the patellar ligament. Reduces friction.
Patella
Largest sesamoid bone in the body. Embedded in the tendon of the quadriceps.
Function of the patella
Assists in knee extension by increasing leverage on the quadriceps tendon.
Patellofemoral joints
A gliding joint which slides inferiorly during knee flexion and superiorly during extension.
Bony landmarks of the tibia
Condyles, tibial tuberosity, soleal line, medial malleolus.
Joints of the tibia
Tibiofemoral, proximal and distal tibiofibular, talocrural.
Joints of the fibula
Proximal and distal tibiofibular, talocrural.
Bony landmarks of the fibula
Head of the fibula, lateral malleolus.
Tarsal bones
Calcaneus, talus, navicular, cuboid, cuneiforms
Calcaneus
Heel bone. Transfers body weight to the ground.
Talus
Ankle bone. Transfers the weight of the body from the leg to the foot.
Navicular
Boat shaped bone on the medial side of the foot.
Cuboid
Cube shaped bone on the lateral side of the foot.
Cuneiforms
3 bones which are distal to the navicular and cuboid.
Talocrural joints
The talus articulates with the tibia and fibula to form a hinge joint.
Motions of the talocrural joint
Plantarflexion and dorsiflexion.
Subtalar joint
The talus articulates with the calcaneus to form a saddle joint.
Motions allowed by the subtalar joint
Inversion and eversion of the foot.
Tarsometatarsal joints
Joints between the metatarsals, cuboid and all 3 cuneiforms.
Arches of normal feet
Longitudinal and transverse.
Peroneus longus
Another name for fibularis longus
Actions of gastrocnemius
Can only be performed one at a time.
