Final answer:
The term 'pelvimeter' refers to an instrument used to measure the dimensions of the pelvis in obstetric examinations. The structure of the pelvis varies between males and females, with females generally having a wider and shallower pelvis to accommodate childbirth.
Step-by-step explanation:
The word that refers to an instrument for measuring the pelvis is 'pelvimeter'. A pelvimeter is used predominantly in obstetrics to measure the dimensions of the pelvis, aiding in determining whether a pregnant woman is capable of delivering a baby naturally. Greater pelvis is the superior and larger region of the pelvis, while lesser pelvis is the narrower, inferior region.
Difference between these two is separated by the pelvic brim. The pelvic outlet is the lower opening of the pelvis, which is larger in females to accommodate childbirth. The structure of the pelvis differs between males and females, with the female pelvis generally being wider and shallower to facilitate childbirth.
