Pronunciation: [ɹˈaməs pjˈuːbɪs] (IPA) 
Ramus pubis is a term used to describe a portion of the pelvic bone. The spelling of the word can be confusing for some, as it contains a silent "b" and "s" at the end. To understand how the word is spelled, we can use the International Phonetic Alphabet (IPA) which shows the pronunciation as /ˈreɪməs ˈpjuːbɪs/. The "a" in "ramus" is pronounced as /eɪ/ while the "u" in "pubis" is pronounced as /juː/.
The ramus pubis is a term used in anatomical and medical contexts to refer to one of the components of the pelvis bone, specifically the pubic bone. The pelvis is a complex structure that forms the lower part of the torso and provides support for the abdominal organs, as well as serving as an attachment point for the lower limbs.
The pubic bone, also known as the os pubis, is a butterfly-shaped bone located in the anterior part of the pelvis, forming the front portion of the pelvic girdle. It consists of two symmetrical halves that come together at the pubic symphysis, a fibrocartilaginous joint.
Each half of the pubic bone consists of two main regions: the body and the ramus. The body of the pubic bone contributes to the formation of the pubic arch, along with the ischium. Meanwhile, the ramus pubis extends laterally from the body and joins with the corresponding ramus of the ischium bone to form the ischiopubic ramus, which completes the structure of the obturator foramen.
The ramus pubis serves as an attachment site for various muscles and ligaments involved in pelvic stability and movement. It also plays a crucial role in the differentiation of the male and female pelvis, with gender-specific characteristics influenced by the size, shape, and orientation of the ramus pubis.
Ramus of the pubis, one of the two portions of the pubis forming the margin of the obturator foramen; the superior or ascending ramus passes upward and outward from the junction with the inferior ramus to the acetabulum; the inferior or decending ramus passes downward and outward from the angle to join the inferior ramus of the ischium.

The word "ramus pubis" is derived from Latin. Here is the breakdown:
1. "Ramus" is a Latin noun meaning "branch" or "limb".
2. "Pubis" is a Latin noun, specifically the genitive form of "pubes", which means "pubic hair" or "groin".
Therefore, "ramus pubis" can be translated as "branch of the pubic hair" or "limb of the groin", referring to the anatomical structure in the pelvic region.
