Common iliac arteries
The average width of a grandmother's pelvis at the pelvic brim can vary, but it is generally around 11-13 cm (4.3-5.1 inches). It's important to note that measurements can differ based on individual variations in anatomy.
The extension of the pelvis that encircles the apex of the pyramid is called the pelvic brim, also known as the pelvic inlet. It is the upper border of the pelvic cavity and is defined by the bony edges of the pelvic bones.
The false pelvis is located above the pelvic brim (Inlet) and is more of an abdominal cavity than a pelvic one (Hence the name False). It houses the some abdominal organs like the small intestine.
The male and female pelvic areas vary in a number of ways, as required by the differences in internal organs and their function. The most obvious difference is a shorter, broader pelvis in females, which is limited by the need to articulate the hips and legs (to walk upright in a normal manner).Characteristics of Male Pelvis :Bone are taller, heavier, and thickerMore prominent bone markingsObturator foramen is roundPubic arch v-shapedPelvic inlet heart-shapedSmaller pelvic outlet smallerIschipubic rami is more evertedSciatic notch is narrowerSubpubic arch is more acuteIschial spine is projected inwardsAcetabulum is largerCharacteristics of Female Pelvis :Bones are lighter and less denseWider / shallower profileLarger superior and inferior aperturesObturator foramen is ovalPubic arch widerPelvic inlet oval-shapedIschiopubic rami is less evertedSciatic notch is widerSubpubic arch is widerIschial spine is projected outwardsAcetabulum is smaller
The Xiphoid process.The xiphoid process is found in the upper abdomen. In the lower abdomen, the only bony prominence found is just as you enter the pelvis, at the upper anterior pelvic brim is the symphisis pubis (or pubic symphisis), a cartilaginous joint where the two pelvic bones meet anteriorly.
Femoral Arteries <---incorrect it forms the common iliac arteries.

The edge of the pelvis is called the pelvic brim or pelvic inlet. It is the upper border of the true pelvis and serves as a boundary between the false pelvis above and the true pelvis below. The pelvic brim plays a crucial role in obstetrics, as it defines the dimensions through which a baby must pass during childbirth.
The greater pelvis, also known as the false pelvis, is the upper part of the pelvic cavity, situated above the pelvic brim and primarily supports the abdominal organs. In contrast, the lesser pelvis, or true pelvis, lies below the pelvic brim and is involved in childbirth, as it contains the birth canal. The greater pelvis is wider and more shallow, while the lesser pelvis is narrower and deeper, making it more relevant for pelvic measurements during delivery.
Brim means that the baby is head down but just above the pelvis an not engaged. Until you go into labour.

A woman's pelvis is shaped like a bowl with the bottom cut off where the top of the pelvis is known as the brim and the bottom is the outlet. At the end of the pregnancy the head of the baby (or w/e part born first) is settled into the bottom of the pelvis. Relation to the brim describes how much of the head can be felt above the pelvis. This is measured in fifths (1 out of 5, 2 out of 5, 3 out of 5 etc). When it's 5 out of 5 it means that no part of the head is in the pelvis and 4 out of 5 means that the top of the head is in the pelvis etc. So your baby's head is halfway. When it's 0 out of 5 the baby is almost born.
The female pelvis is shaped like a bowl with the bottom cut off. The top of the pelvis is called the brim and the bottom is called the outlet. Towards the end of pregnancy the part of the baby which is born first (hopefully the head) settles into the pelvis. This is called engagement Relation to brim describes how much of the head can be felt above the pelvis. It is usually measured in fifths. 5/5 means that no part of the head is in the pelvis. 4/5 means that the top part of the head is in the pelvis and so on. By the time the head is 0/5 the baby is almost born at the end of labor. If at the end of a first pregnancy the midwife or ob/gyn can still feel 5/5 of the baby's head it may mean that the baby is too large to be born naturally. With second or later babies the head may not go into the pelvis until the mother goes into labor.
Some babies settle down in the pelvis of the pregnant woman. This is what happened to me. My baby was low my entire pregnancy.

By 'lying in the brim' we mean that the baby's head is just at the top of the bony pelvis (pelvic brim) so the head is not engaged but almost certainly will be soon. As you have only 4 weeks until your due date it sounds as though everything is going in the right direction - that is downwards! sounds to me like she is referring to the head of the baby is crowning, meaning that it is approaching the vaginal opening.
