It is known as the ischium.

The ischium is part of the pelvis.

Question 11

What landmarks is the pelvic brim made up of?

Question 13

What does the bony pelvis consist of?

Answer 13

The bony pelvis consists of 2 hip bones (right and left), sacrum (vertebra), and coccyx (vertebra).

Question 14

What are the components of the hip bones?

Answer 14

The hip bones consist of ilium, pubis, and ischium.

Question 15

What are the three main joints in the pelvis?

Answer 15

The three main joints in the pelvis are the two sacroiliac joints and the pubic symphysis.

Question 16

What does the bony pelvis consist of?

Answer 16

2 hip bones (right and left), sacrum, coccyx

Question 17

What are the components of the hip bones?

Answer 17

ilium, pubis, ischium

Question 18

What are the three main joints in the pelvis?

Answer 18

1. Sacroiliac joints (synovial, plane)
2. Pubic symphysis (symphysis, secondary cartilaginous)
3. Sacrococcygeal joint (secondary cartilaginous)

Question 19

What ligaments compose the sacroiliac joint?

Answer 19

The anterior, interosseous, and posterior sacroiliac ligaments

Question 20

What type of joint is the sacroiliac joint?

Answer 20

Synovial plane joint with little gliding movement early on in life

Question 21

What happens to the pelvic ligaments during childbirth?

Answer 21

1. Release of pregnancy hormone relaxin (from ovaries and placenta)
2. Ligaments of the pelvis are relaxed
3. Joints move (e.g., sacrum/coccyx tilt upwards, providing space for the child to pass through)

Question 22

What is the pelvic inlet?

Answer 22

The false inlet, containing parts of the lower abdominal organs

Question 23

What is the pelvic outlet?

Answer 23

The true pelvis, containing parts of the birth canal in females and parts of the reproductive tracts in both males and females

Question 24

Do the different shapes of pelvic apertures significantly affect birth outcomes?

Answer 24

No, the influencing factors are fetus size (especially head) and position

Question 25

How is the pelvis oriented?

Answer 25

Tilting forwards such that a coronal section will pass through the anterior superior iliac spines and the pubic tubercles

Question 26

What are some differences between the female and male bony pelvis?

Answer 26

Female: cylindrical pelvic wall, wide pubic arch Male: tapered pelvic wall, narrow pubic arch

Question 27

What is a tubercle?

Answer 27

A small rounded projection

Question 28

What is a tuberosity?

Answer 28

A spongy, tuberous region

Question 29

What is a spine?

Answer 29

A short prominence of bone

Question 30

What is a fossa?

Answer 30

A deep groove

Question 31

What is a foramen?

Answer 31

An opening/hole

Question 32

What is a ramus?

Answer 32

A branch

Question 33

What is the width of the pelvic inlet?

Answer 33

Around 13cm with an oval shape, the transverse diameter being the largest dimension

Question 34

What is the width of the pelvic midplane?

Answer 34

Around 10cm with a circular shape (all dimensions roughly equal)

Question 35

What is the width of the pelvic outlet?

Answer 35

Around 11cm with an oval shape, the anteroposterior diameter being the largest dimension

Question 36

What muscle creates the puborectal sling?

Answer 36

The puborectalis muscle stops yourself from painting your carpets brown by creating a puborectal sling.

Question 37

What is the shape of the perineum when viewed inferiorly?

Answer 37

The perineum is diamond-shaped.

Question 38

What are the two triangles that the perineum can be split into?

Answer 38

The perineum can be split into the posterior anal triangle and anterior urogenital triangle.

Question 39

What bounds the perineum?

Answer 39

The perineum is bounded by the pubic symphysis, the ischial tuberosities, and the coccyx.

Question 40

What does the anal triangle contain?

Answer 40

The anal triangle contains the anal canal and the ischioanal fossa.

Question 41

What is the ischioanal fossa?

Answer 41

The ischioanal fossa is a fat-filled space on each side of the anal canal made up of the ischioanal space and perianal space.

Question 42

What does the urogenital triangle contain?

Answer 42

The urogenital triangle contains the superficial perineal pouch and deep perineal pouch (urogenital diaphragm).

Question 43

What does the deep perineal pouch (urogenital diaphragm) house in males?

Answer 43

The deep perineal pouch houses the bulbourethral gland in the male.

Question 44

What muscles help maintain hard pp and clitoris?

Answer 44

The ischiocavernosus and bulbospongiosus muscles help maintain hard pp and clitoris.

Question 45

What is the function of the superficial transverse perineal muscle?

Answer 45

The superficial transverse perineal muscle helps support the perineal body and reinforces its attachments.

Question 46

What does the superficial perineal pouch contain?

Answer 46

The superficial perineal pouch contains external genitalia.
