Answer 16

lies just inferior to the spine of the scapula; comprises majority of the posterior surface of the scapula

Question 17

Pelvic brim

Answer 17

a continuous oval ridge that extends from the pubic crest, peritineal line, and arcuate line to the rounded inferior edges of the sacral ala and promontory; subdivide the entire oelvis into a true pelvis and a false pelvis

Answer 29

adjacent to the posterior inferior iliac spine; through which sciatic nerves travel to the lower limb

Question 30

Auricular surface

Answer 30

a large, roughened area on the posteromedial side of the ilium; where the ilium articulates with the sacrum at the sacroiliac joint

Question 31

Ischial spine

Answer 31

posterior to the acetabulum; prominent triangular spine projects medially

Question 32

Ischial tuberosity/sitz bones

Answer 32

a roughened projection on the posterolateral border of the ischium; support the body when seated

Question 33

Lesser sciatic notch

Answer 33

a semicircular depression inferior to the ischial spine

Question 34

Pubic tubercle and crest

Answer 34

Tubercle: an attachmetn site for the inguinal ligament; on the anterosuperior surface of the superior ramus Crest: a roughened ridge on the anterosuperior surface of the superior ramus and ends at the pubic tubercle

Question 35

Pubic symphysis/Symphysial surface

Answer 35

roughened area on the body of the pubis; denotes the site of articulation between the pubic bones
