F

True/False The bones of the skull develop from mesenchymal cells of the mesoderm.

By what week of development does endochondral ossification of the bones of the limbs begin? a) by the end of the 4th week b) by the end of the 5th week c) by the end of the 6th week d) by the end of the 7th week e) by the end of the 8th week

T

True/False The coracoid process of the scapula does not articulate with any bone, but it is an attachment site for tendons and ligaments.

T

True/False The articular facets of the patella articulate with the medial and lateral condyles of the femur.

1 lunate 3 scaphoid 4 triquetrum

The distal end of the radius articulates with which three bones of the wrist? 1 lunate 2 capitate 3 scaphoid 4 triquetrum 5 hamate

The embryonic skull begins developing during the fourth week after fertilization. Which part of these embryonic connective tissues will eventually form the facial bones? a) the cartilaginous neurocranium b) the membranous neurocranium c) the cartilaginous viscerocranium d) the membranous viscerocranium e) the mesenchyme

d) the ischium and pubis

The obturator foramen is the largest foramen in the body, but is nearly completely closed by the obturator membrane (but nerves and blood vessels are still able to pass through). This foramen is formed by which structures of the pelvic girdle? a) ilium and ischium b) ilium and pubis c) the anterior edge of the acetabulum and the pubis d) the ischium and pubis e) the ilium, ischium, and pubis

c) arcuate lines

The superior and inferior regions of the bony pelvis are separated by a series of landmarks that indicate a boundary known as the pelvic brim (pelvic inlet). These landmarks are the sacral promontory, the __________ of each ilium, and along the superior edges of each pubic bone, and the pubic symphysis. a) pectilineal lines b) iliac crest c) arcuate lines d) the pubic crests e) ramus

F

True/False The bones of the foot are held in place by tendons and ligaments and form two arches:the transverse and lateral arches. These arches are rigid, and by the time a child is 12 or 13, they are fully formed and inflexible. This rigidity enables us to walk with greater ease.

T

True/False A broad, flat sheet of connective tissue called an interosseous membrane connects the bones of the forearm (radius and ulna).

T

True/False At birth, each hip bone is composed of three separate bones which aren't completely fused until the person is in their early 20's.

T

True/False In the embryo, both upper and lower limb buds have appeared before the beginning of the fifth week of development.

T

True/False Nearly all the differences between the female and male pelves are adaptations of the female pelvis to accommodate childbirth.
