Which of the following arteries is a direct continuation of the inferior mesenteric artery?

The ovarian arteries arise from which of the following arteries?
The ovarian arteries arise from the abdominal aorta
The superior gluteal artery leaves the pelvis through which of the following openings?
The superior gluteal artery leaves the pelvis through the superior part of the greater sciatic foramen, superior to the piriformis muscle, to supply the gluteal muscles in the buttocks
Which of the following structures separates the bladder from the pubic bones in females?
Please select 2 correct answers
When empty, the adult male or female urinary bladder is in the lesser pelvis, lying posterior and slightly superior to the pubic bones. It is separated from these bones by the potential retropubic space and lies inferior to the peritoneum, where it rests on the pelvic floor
The lesser vestibular glands open into which of the following structures?
The slender ducts of the greater vestibular glands pass deep to the bulbs of the vestibule and open into the vestibule on each side of the vaginal orifice. The lesser vestibular glands are small glands on each side of the vestibule that open into it between the urethral and vaginal orifices
The neck of the bladder in females is held firmly by which of the following structures?
The bladder is relatively free within the extraperitoneal subcutaneous fatty tissue except for its neck, which is held firmly by the puboprostatic ligaments in males and the pubovesical ligaments in females
Helicine arteries are located in which of the following structures?
The deep arteries of the penis are the main vessels supplying the cavernous spaces in the erectile tissue of the corpora cavernosa and are therefore involved in the erection of the penis. They give off numerous branches that open directly into the cavernous spaces. When the penis is flaccid, these arteries are coiled and therefore are called helicine arteries
Which of the following structures may be referred to as the fourchette?
In young women, especially virgins, the labia minora are connected by a small fold known as the frenulum of the labia minora or the fourchette
