wrist ligamenst attach to the
styloid processes of the radius and ulna
Chapter 8 - The Appendicular Skeleton
wrist has how many bones
8 carpal bones
Chapter 8 - The Appendicular Skeleton
carpal bones

one or two _______ often form near the junction between proximal phalanx and the metacarpal of the thumb
sesamoid bones
Chapter 8 - The Appendicular Skeleton
the lower limb is attached solidly to the _____
coxa
Chapter 8 - The Appendicular Skeleton
function of the pelvic girdle
support and locomotion
Chapter 8 - The Appendicular Skeleton
the pelvic girdle consists of
2 ossa coxae (hip bones)
Chapter 8 - The Appendicular Skeleton
each os coxa is formed by the fusion of
ilium
ischium

Chapter 8 - The Appendicular Skeleton
inside the ________, the ilium is fused to the ischium (posteriorly) and the pubic (anteriorly)
acetabulum
Chapter 8 - The Appendicular Skeleton
the coxae are connected ventrally by a pad of fibrocartilage at a joint called
pubis symphysis
Chapter 8 - The Appendicular Skeleton
function of the pubis symphysis
limits movement between pubis bones of the left and right coxae
Chapter 8 - The Appendicular Skeleton

subdivisions of the pelvis are
false (greater) pelvis
true (lesser) pelvis
Chapter 8 - The Appendicular Skeleton
the true pelvis encloses
the pelvic cavity, a subdivision of the abdominopelvic cavity
Chapter 8 - The Appendicular Skeleton
the bony edge of the true pelvis is called the
