The rami of the pelvis are the three bony parts that form the sides and front of the pelvis. They are the ischial, pubic, and iliac rami. The ischial ramus is the thickest and strongest of the three rami and forms the posterior border of the obturator foramen. The pubic ramus is the anterior border of the obturator foramen and articulates with its counterpart from the opposite side to form the pubic symphysis. The iliac ramus is the superior border of the obturator foramen and connects the ilium to the ischium and pubis. Together, the rami of the pelvis form a ring of bone that supports the pelvic organs and provides attachment for muscles.
Best Structure for Ramus of the Pelvis
The ramus of the pelvis is a bony structure that forms the lower part of the pelvic ring. It consists of two parts: the superior ramus and the inferior ramus.
The superior ramus is a thick, triangular bone that extends from the pubic bone to the ilium. It forms the upper border of the obturator foramen, a large opening in the pelvis. The inferior ramus is a thin, curved bone that extends from the ischium to the pubic bone. It forms the lower border of the obturator foramen.
The ramus of the pelvis is an important structure for supporting the weight of the body and providing attachment for muscles. It also helps to protect the pelvic organs.
Superior Ramus
- Thick, triangular bone
- Extends from the pubic bone to the ilium
- Forms the upper border of the obturator foramen
Inferior Ramus
- Thin, curved bone
- Extends from the ischium to the pubic bone
- Forms the lower border of the obturator foramen
Table: Ramus of the Pelvis
| Part | Description |
|---|---|
| Superior Ramus | Thick, triangular bone that forms the upper border of the obturator foramen |
| Inferior Ramus | Thin, curved bone that forms the lower border of the obturator foramen |
Question 1:
What is the definition of the rami of the pelvis?
Answer:
The rami of the pelvis are the three pairs of bony projections that extend from the ilium, ischium, and pubis bones to form the pelvic brim and outlet.
Question 2:
What are the names of the three rami of the pelvis?
Answer:
The three rami of the pelvis are the superior pubic ramus, the inferior pubic ramus, and the ischial ramus.
Question 3:
What is the function of the rami of the pelvis?
Answer:
The rami of the pelvis form the bony boundaries of the pelvic cavity and support the weight of the overlying organs and structures.
