Question 8

ischial tuberosity

Answer 8

 A rough, rounded inferior surface. Acts as a projection
- the primary weight bearing point when sitting down, attachment for many muscles of the posterior thigh, and the hamstrings, allows for hip movement

Question 9

ischial spine

Answer 9

 Is inferior to the greater sciatic notch, and projects medially toward the girdle to provide attachment for the sacrum.
- attachment for ligaments which control the movement of the sacrum. Also helps determine the baby’s head position during labor

Question 10

lesser sciatic notch

Answer 10

 Is located inferior to the ischial spine and is where nerves and vessels pass through.

Question 11

pubis is?

Answer 11

pointy
- protects the bladder, intestines, and the internal sex organs

Question 12

obturator foramen of the pubis

Answer 12

 A large hole in the bone which allows for attachment of the hip muscles and ligaments.
* Hello, obturator.
- passage for nerves and blood vessels, allows for inner action of the adductor muscles responsible for thigh adduction

Question 13

pubic symphysis

Answer 13

 A tall oval flat surface has cartilage separating the two pelvic bones.
Works to stabilize the pubic bones together, allows for slight movement and absorption of shock

Question 14

pubic tubercle

Answer 14

a bump projecting forward to allow attachment for the inguinal
- a point of attachment for the inguinal ligament and muscles

Question 15

head of the femur

Answer 15

a ball like top (head) with a pit in the center

Question 16

fovea capitis of the femur

Answer 16

o A point of attachment for ligaments to attach the femur to the acetabulum

Question 17

neck of the femur

Answer 17

connects the head of the femur to the neck

Question 18

greater trochanter of the femur

Answer 18

o Is on the proximal and lateral side, and points towards the feet.
 Is much bigger than the tubercle.
- attachment point for muscles that move the hip

Question 19

lesser trochanter of the femur

Answer 19

o Is a smaller point for attachment. Located below the greater and is on the opposite side of the bone.
 Is bigger than the tubercle.
- attachment point for muscles that help with hip flexion, rotation, thigh stabilization, and lower extremity function

Question 20

linea aspera of the femur

Answer 20

o Is a point of attachment for the hip muscles. Is in the middle of the bone shaft
- provides attachment for the muscles that extend and adduct to the thigh

Question 21

lateral and medial epicondyles of the femur

Answer 21

articulates with the muscles
- attachment sites for the ligaments of the knee

Question 22

lateral and medial condyles

Answer 22

articulates with the tibia
- primary articulation point for knee joint

Question 23

intercondylar fossa

Answer 23

o Is a deep depression between the condyle and epicondyle. Is located posteriorly.
- attachment site for the ACL, and the PCL

Question 24

patellar surface

Answer 24

a smooth surface located anteriorly which articulates with the patella
- a bone shield that protects the knee

Question 25

apex of the patella

Answer 25

o A point sticking up inferiorly, which points to the feet.

Question 26

articular surface of the patella

Answer 26

o A smooth curved surface, on the posterior side. The articular surface articulates with the femur

Question 27

lateral condyle of the tibia

Answer 27

o On the superior proximal side, is what articulates these condyles with the femur.
- provides a stable articulation surface to connect with the lateral condyle of the femur, attaches to ligaments and tendons that stabilize the joint

Question 28

medial condyle of the tibia

Answer 28

o On the proximal side, is what articulates these condyles with the femur.
- attachment to the knees ligaments, muscle insertion, joint formation, and movement of the knee (locking out)

Question 29

tibial tuberosity

Answer 29

o A projection on the side, you can feel is on your own body just below the knee joint. Is the attachment point for the patellar ligament.

Question 30

anterior crest/margin of the tibia

Answer 30

o A sharp crest on the anterior side is a bump of bone on the medial side. Runs all the way down the leg.

Question 31

medial malleolus of the tibia

Answer 31

o Is a bump of bone on the medial side, we can feel this on the middle of the ankle.
- supports the ankle joint and helps maintain its stability

Question 32

fibular notch of the tibia

Answer 32

o An indentation on the lateral distal side, is where the distal end of the fibula sits.
