Question

Predict what might happen if the greater and /or lesser sciatic notches of the ilium were abnormally small and narrow . Explain ( Hint : Consider the function of these notches .)

Answer 1

Answer:

If the greater and/lesser sciatic notches of the ilium were abnormally small and narrow, it has less modification effects on males but can considerably caused difficulties in child deliveries in females.

This is explained below

Explanation:

In cases if the greater sciatic notches of the ilium are unusually small and narrow, it will not cause any modifications in males. However, this is not the cases in females in a way that if the greater sciatic notches of the ilium were unusually small and narrow, then it would become difficult for the baby to pass through the pelvis at the time of delivery, thus resulting in complications during childbirth.

Due to this, the normal delivery would get complicated resulting in breathing complications and may even be fatal for the child.

The large, inverted U-shaped depression found in the posterior margin of the lower ilium is known as the greater sciatic notch. The marginally bent posterior margin of the ischium above the ischial tuberosity is the lesser sciatic notch. The body protrusion distinguishing the greater sciatic notch and the lesser sciatic notch is the ischial spine.

The greater sciatic notch of the male hip bone is deeper and narrower in comparison to the broader notch of the females. As the female pelvis is amended for childbirth, it is broader in comparison to the male pelvis, as proved by the distance between the anterior superior iliac spines.

Answer 2

Answer:However, in females, if the greater sciatic notches of the ilium were unusually small and narrow, then it would become difficult for the baby to pass through the pelvis at the time of delivery, thus resulting in complications during childbirth.

In males, if the greater and/or lesser sciatic notches of the ilium were abnormally small and narrow. It doesnt cause any changes. 

Explanation:the

lesser sciatic notch ; it is smooth, coated in the recent state with cartilage, the surface of which presents two or three ridges corresponding to the subdivisions of the tendon of the Obturator internus , which winds over it.

It is converted into a foramen, the lesser sciatic foramen, by the sacrotuberous and sacrospinous ligaments, and transmits the tendon of the Obturator internus, the nerve which supplies that muscle, and the internal pudendal vessels and

pudendal nerve.
