18
Q

What are the perineal muscles?

A

form the floor of the pelvis which is supporting the organs

19
Q

What are characteristics of the female pelvis that differ from the male pelvis?

A

wider, smoother, lighter, & less prominent markings; less curvature of sacrum & coccyx

20
Q

What is the femur (thigh)?

A

heaviest & strongest bone in the body

21
Q

What is the head of femur?

A

articulates with acetabulum to form ball-and-socket joint of the hip

22
Q

What are the greater & lesser trochanters, intertrochanteric crest, & gluteal tuberosity?

A

on the femur; sites for muscle attachment

23
Q

What are the lateral & medial condyles of the femur?

A

at the distal end of femur; articulate with the tibia

24
Q

What is the patellar surface?

A

anterior surface that articulates with the tibia

25
Q

What is the intercondylar fossa?

A

deep groove between the condyles on posterior side

26
Q

What are the medial & lateral epicondyles?

A

sites for knee ligament attachments

27
Q

What are the bones of the lower leg?

A

tibia & fibula

28
Q

What is the tibia?

A

shin bone

29
Q

What is the interosseous membrane?

A

joins the tibia & fibula along their lengths

30
Q

What are the medial & lateral condyles of the tibia?

A

articulate with femur to form knee joint

31
Q

What is the tibial tuberosity?

A

on anterior tibial surface; site for patellar tendon/ligament attachment

32
Q

What is the medial malleolus?

A

on the tibia; forms medial bulge of the ankle; articulates with the talus of the ankle

33
Q

What is the anterior crest?

A

sharp ridge along anterior length of tibia

34
Q

What are characteristics of the fibula?

A

not part of the knee joint; it is a non weight-bearing bone

35
Q

What is the head of the fibula?

A

proximal end; articulates with lateral condyle of tibia

36
Q

What is the lateral malleolus?

A

on the fibula; forms lateral bulge of the ankle

37
Q

What is the ankle?

A

7 tarsal bones

38
Q

What tarsal bones is body weight concentrated on?

A

talus & calcaneous

39
Q

What does the talus articulate with?

A

distal end of tibia

40
Q

What is the calcaneous?

A

the heel of the foot

41
Q

What are the 7 tarsal bones?

A

navicular, cuboid, talus, calcaneous, medial cuneiform, intermediate cuneiform, & lateral cuneiform

42
