RAD 113 Chapter 7 part A
acetabular notch
A gap on the inferior margin of the rim of the acetabulum.
lateral condyle of femur
Articulates with lateral condyle of the tibia to form the knee joint
pelvic girdle
Consists of the *paired coxal bones* (hip bones) that attach the lower limbs to the axial skeleton.
os coxae
________ also known as hip bone.
ilium, ischium, pubis
___________ are bones that fuse to form the coxal bone (hip bone)
pubic arch
a curved surface formed by the medial margins of both inferior rami of the pubic bones and the lower border of the symphysis pubis.
Acetabulum
a deep circular cup shaped depression on the lateral surface of the hip bone, below its middle. This circular depression forms a socket for the head of the femur at the hip joint.
intercondylar fossa
a deep notch located between the posterior parts of the femoral condyles.
greater sciatic notch
a deep notch on the posterior margin of the hip bone. it lies between the posterior inferior spine of the ilium above, the spine of ischium below.
linea aspera
a double bony ridge that passed longitudinally down the posterior surface of the body of the femur.
obturator foramen
a large opening in the inferior part of the hip bone, between the pubis and ischium.
greater trochanter
a large prominence on the lateral surface of the upper femur.
femur
a long bone; the longest bone in the body. it is slight curved; it articulates with the hip bone to form ball and socket joint.
spine of ischium
a pointed process that extends dorsally and medially from the body of the ischium.
posterior superior iliac spine
a prominence at the posterior end of the crest.
intertrochanteric crest
a ridge of bone that passes obliquely across the back of the upper femur between the greater and lesser trochanters. (on the posterior view)
intertrochanteric line
a ridge that extends obliquely across the anterior surface of the upper femur, from the greater trochanter to the medial border of the femur in front of the lesser trochanter.
auricular surface
a rough, ear-shaped part, posterior to the iliac fossa, that *articulates with the upper lateral part of the sacrum.*
adductor tubercle
a small process on the medial surface of the medial epicondyle.
lateral epicondyle
a smaller rounded process on the lateral surface of the lower femur above the lateral condyle.
ilium
also known as flank bone. It forms the upper two-fifths of the acetabulum and all of the hip bone above it.
patella
also known as the kneecap, is the bony anterior portion of the knee. it has a base and apex.
false pelvis
another name for major pelvis. lies above the plane of the inlet, that is above the true pelvis.
true pelvis
another name for minor pelvis. is the cavity located between the pelvic inlet and the pelvic outlet
head of femur
articulates with the acetabulum to form the hip joint
medial condyle of femur
articulates with the medial condyle of the tibia at the knee joint.
neck of femur
constricted part connecting the head to the body of the femur.
superior ramus of pubis
extends anteriorly from the body to the symphysis pubis.
inferior ramus of pubis
extends down from the lower end of the superior ramus, and joins the ramus of the ischium.
ramus of ischium
formerly named the inferior or ascending ramus, extends anteriorly, medially and upward from the body
pubis
forms the anterior one-fifth of the acetabulum and the anterior part of hip bone in front of the acetabulum and obturator foramen.
ischium
forms the lower two-fifths of the acetabulum and that part of the hip bone below and dorsal to the acetabulum.
pelvis
has the right and left hip bones, the sacrum, and coccyx.
tuberosity of ischium
is a large rounded process on the posterior surface of the lower end of the body of the ischium.
lesser trochanter
is a much smaller rounded process that extends medially from the posteromedial margin of the upper femur at the junction of the neck and shaft.
linea terminalis
is a ridge of bone that begins at the upper margin of the symphysis pubis. It runs along the upper margin of the pubis, it then crosses the medial surface of the ilium.
posterior surface of patella
is a smooth and glides over the smooth patellar surface of the femur as the kneed is flexed or extended.
body of femur
is the long cylindrical part that becomes broadened as it approaches the knee.
lesser sciatic notch
lies between the spine of the ischium above, and the ischial tuberosity below. it is below the greater notch and is much smaller.
anterior inferior iliac spine
lies on the anterior margin of the ala about on inch below the anterior superior spine. It cannot be palpated.
apex of patella
the lower pointed end of the patella.
anterior superior iliac spine
the prominent anterior end of the iliac crest; it can be easily palpated.
base of patella
the proximal slightly rounded upper border.
patellar surface
the smooth anterior surface of the distal part of the femur between the anterior parts of the femoral condyles. it forms a joint with the patella.
larger and more rounded
the superior inlet of the female pelvis is _______________, while in the males it is more heart shaped.
body of ilium
the thickened part close to the acetabulum, of which it forms the upper two-fifths.
the ala or wing
the thin flattened upper part of the ilium above the body.
crest of ilium
the upper curved border of the ala. It can be palpated. It is a very important landmark for radiologic technologist for centering.
pubic tubercle
very small process on the superior margin of the pubic bone, slightly lateral to the symphysis pubis.
prominent
the hips in the female appear to be more ______.
pubic crest
small ridge on the upper margin, extending from the symphysis to the pubic tubercle.
iliac fossa of ilium
the concave inner surface of the wing of the ilium.
flared outward
the female iliac crests are __________ more, and they are less curved.
popliteal surface
the flat area on the dorsal surface of the lower femur between the divided ridges of the linea aspera.
acetabular fossa
the flat central part of the acetabulum. the head of the femur rests upon the rim of this cup.
