Clinical Anatomy of the Bony Pelvis

Name the three bones of the bony pelvis (in alphabetical order). [blank_start]Ilium[blank_end] [blank_start]Ischium[blank_end] [blank_start]Pubis[blank_end]

Label the parts of the bony pelvis shown below:

Label the joints of the bony pelvis as shown below:

What type of joint is the hip joint?

What type of joint is the pubic symphysis?

The 'wing' of the sacrum is also known as an [blank_start]ala[blank_end] of the sacrum

The point at which the inferior pubic ramus meets the inferior ramus of the ischium is called the [blank_start]ischiopubic[blank_end] ramus

The parts of the bony pelvis we typically sit on are called the ...

Name the labelled structures of the pelvic bone:

The [blank_start]inguinal[blank_end] ligament attaches between the ASIS and the pubic tubercle

Which structure of the gut sits in the left iliac fossa?

The posterior superior iliac spine in found at which vertebral level?

The origin of the [blank_start]hamstring[blank_end] muscle group is at the [blank_start]ischial tuberosity[blank_end]

What structure forms the faint arch labelled on the xray below?

Label the xray (no abbreviations):

This foramen is named the __________ foramen

Name the two ligaments of the pelvis that form the greater and lesser sciatic foramen (most anterior first). [blank_start]Sacrospinous[blank_end] ligament [blank_start]Sacrotuberous[blank_end] ligament

Label the following ligaments on the diagram below.

Attaches between ischial spine and sacrum = [blank_start]Sacrospinous Ligament[blank_end] Attaches between ischial tuberosity and sacrum = [blank_start]Sacrotuberous Ligament[blank_end] Attaches between superior ramus of the ischium and sacrum = [blank_start]Neither[blank_end]

The most prominent part of the sacrum is known as the sacral [blank_start]promontory[blank_end]

Which muscle is also known as the pelvic floor? [blank_start]Levator Ani[blank_end] Muscle

Which nerve wraps around the sacrospinous ligament before re-entering the pelvis, allowing an anatomical landmark at which nerve conduction block can be conducted? [blank_start]Pudendal[blank_end] Nerve

The subpubic angle is wider in males than it is in females.

Males typically have a larger sacral promontory than females.

The term “[blank_start]moulding[blank_end]” refers to the movement of one bone over another to allow the foetal head to pass through the pelvis during labour.

Diameters of the foetal skull: Horizontal = _________ Diameter Longitudinal = _________ Diameter

Which diameter of the foetal skull is longest? The [blank_start]Occipitofrontal[blank_end] Diameter

Childbirth in relation to the foetal skull: Baby should pass through pelvic inlet facing [blank_start]right/left[blank_end] Baby should pass through pelvic outlet facing [blank_start]posteriorly[blank_end] and the head should be in [blank_start]a flexed position[blank_end] During delivery the foetal head should be in [blank_start]extension[blank_end]

Once the baby's head has been delivered in the occipitoanterior position, the foetus should then be turned 180 degrees to face anteriorly in order to deliver the shoulders

Bulging of Fontanelles indicates [blank_start]raised ICP[blank_end]

Recession of fontanelles typically indicates which two of the following?

The Linea [blank_start]Terminalis[blank_end] is another term for describing the pelvic inlet

Label the lumbosacral plexus shown below

The Obturator and Femoral Nerves both arise from nerve roots ...

The Pudendal Nerve arises from levels ...
