QuestionAnswer
when classifying bones based on shape, the patella is classified as a ____________ bone sesamoid/round
the tibia, fibula, and the talus form a true ________ type of synovial joint. hinge
flexion at the hinge joint between the tibia, fibula, and the talus so that the toe points upwards is _____________ while extension at this joint so that the toes points downwards is ______________ dorsiflexion; plantar flexion
the prominent projections at the distal ends of the tibia and fibula are called the _________ ________ and the _______ _______, respectively. a syndesmosis joint is formed between this feature on the fibula and the lateral, distal region of the tibia medial malleolous; lateral malleolus
prominent rounded features at the distal end of the femur are the medial and lateral _________ condyles
a cavity called the __________ ___________ is found between the medial and lateral condyles intercondylar fossa
the intercondylar fossa is where the _________ and ____________ ________ ligaments are located anterior and posterior cruciate
the _______________ of the fibula articulates with the tibia just distal to the lateral condyle head/ apex/ styloid process
the three muscles that make up the "hamstring" group are the _________, ___________, and _____________. all of these muscles extend the thigh at the hip and flex the leg at the knee biceps femoris; semimembranosus; semitendinosus
the joint between all metatarsals and their respective proximal phalanx is a _____________ type of synovial joint. movement is biaxial, and these joints are classified as __________ based on their degree of movement condylar; diarthrotic
of the four muscles in the quadriceps muscle group, only the _______ _________ flexes the hip. all of the muscle in this group act to extend the leg at the knee and insert on the tibial tuberosity by means of the patellar tendon rectus femoris
the other 3 muscles in the quad group ar the _________ __________, __________ ____________, and ____________ _____________ vatus lateralis; vastus medialis; vastus intermedius
the muscle on the posterior side of the lower leg that originates on the condyle of the femur and acts to plantar flex the foot is the _______________ gasctrocnemius
the __________ muscle originates on the lower edge of the pubic symphasis and acts to adduct the thigh and flex the leg at the knee gracilis
the distal end of the femur forms a _________ _________type of joint with the tibia as well as a __________ joint with the patella. both are specific types of synovial joints, so based degree of motion both are __________ joints modified hindge; plane; diarthrotic
the muscle that originates on the anterior superior iliac spine and acts to abduct the thigh, rotate the thigh laterally, and flex the lower leg is the __________ sartorius
when classifying bones based on shape, all the bones of the ankle are classified as ________ bones short
the muscle of the anterior region of the lower leg that originates on the lateral condyle of the tibia and acts to dorsiflex the foot is the __________ ___________ tibialis anterior
anatomically the joint at the distal end of the tibia and fibula is an example of a specific type of _____ joint called a ______. these bones are held together by an ______ ligament. based on its degree of movement, this joint is classified as _____ fibrous; syndesmosis; interoseous; amphiarthrotic
the muscle of the posterior region of the lower leg that originates on the tibia and fibula and acts to plantar flex the foot of the _________ soleus
when classifying bones based on shape, all the bones of the leg as well as all bones of the foot are classified as _________ bones long
the muscle group of the lateral region of the lower leg that inserts on to tarsals and metatarsals and acts to evert the foot is the _______ or __________ group fibularis; pernoeus
a special feature of the knee joint is the presence of discs of fibrocartilage called the lateral and medial _________ menisci
