{The gastrointestinal tract has three subdivisions supplied by their own arterial branch from the abdominal aorta. The foregut is supplied by:
|type="()"}
- superior mesenteric artery
- left gastric artery
+ celiac artery
- jejunal artery
- inferior mesenteric artery
||The gastrointestinal tract has three subdivisions (foregut, midgut, hindgut) supplied by their own arterial branch from the abdominal aorta. The '''celiac artery''' supplies the foregut. The superior mesenteric artery supplies the midgut and the inferior mesenteric artery supplies the hindgut. The Left gastric artery is a branch of the celiac artery and the Jejunal artery is a branch of the superior mesenteric artery.

{The gastrointestinal tract embryonic dorsal mesentery forms the adult:
|type="()"}
- falciform ligament
- hepatogastric ligament
- hepatoduodenal ligament
- lesser omentum
+ gastrosplenic ligament
||The '''gastrosplenic ligament''' connects the stomach to the spleen and is derived from the embryonic dorsal mesentery. The remainder of the choices are all formed from the embryonic ventral mesentery.

{The sequential development of the renal structures within intermediate mesoderm can best be described as:
|type="()"}
+ pronephros, mesonephros, metanephros
- pronephros, metanephros, mesonephros
- mesonephric duct, metanephros, mesonephros
- mesonephric duct, paramesonephric duct, metanephros
- uteric bud, ureter, urinary bladder

||The rostro-caudal paired strips of intermediate mesoderm form in a downward sequence: pronephros (in the neck region), mesonephros (along the length of the trunk) and metanephros (at the level of the hindlimbs). The metanephros being the developing adult kidney.

{The sequential development of the genital system can best be described as:
|type="()"}
- internal and external genital tract dependent upon primordial germ cell hormone secretion
+ gonadal differentiation and hormone secretion determining internal then external tract development
- mesonephric duct hormone secretion forming genital ridge then internal and external tract development
- internal tract determining gonadal then hormone secretion for external tract development
- paramesonephric duct forming genital ridge then hormone secretion for internal and external tract development

||Differentiation of the initially indifferent gonad is required before internal tract and then external tract development. Both the latter require gonad development and will be abnormal without this first step. Mesonephric duct is present beside the early genital ridge, but does not induce its differentiation. Paramesonephric duct forms after gonad determnation.

{The allantois, cloaca, hindgut and yolk sac are all lined with endoderm
|type="()"}
+ true
- false
|| During week 3 gastrulation generates the endoderm layer that forms an epithelial layer that with later embryonic disc folding lines all of the above structures.

{The cells in the adult male and female gonad forming from equivalent primordial cells in each sex are:
|type="()"}
- Sertoli cells and thecal cells
- Leydig cells and interstitial cells
- primordial germ cells and oocytes
+ thecal cells and interstitial cells
- ductus deferens and mesonephric ducts
||'''Thecal cells''' (female) and '''interstitial cells''' (male) both form the sex hormone secreting cell population in the gonads. Leydig cells and interstitial cells are 2 names for the same cell in the testis. Primordial germ cells exist in both sexes and do form oocytes, but this is not what the question asked. The ductus deferens is the male internal genital tract formed from the mesonephric ducts.

{Select the correct options below for the embryonic contribution to the female uterus and vagina
|type="[]"}
- Wolffian duct
- Utereric duct
+ Mullerian duct
+ paramesonephric duct
- urogenital sinus

||Mullerian and paramesonephric duct are the same thing and the embryonic contributors to the female uterus and vagina development.

{The relative movement of organs with the peritoneal cavity can best be described as:
|type="()"}
- descent of the adrenal glands and gonads
- ascent of the adrenal glands and genital tubercle
+ ascent of the kidneys and descent of the gonads
- descent of the kidneys and adrenal glands
- none of the above

||The adrenals, kidneys and gonads are initially closely related. Both the adrenals and kidneys are described as moving relatively as ascending, while the gonads (both ovary and testis) move away in relative descent.

{The genital tubercle and inner genital folds form the same adult structures in both sexes.
|type="()"}
- true
+ false
|| In the fetus, the genital tubercle and genital folds appear as the same external genital structures in both sexes and differentiate to form different adult structures.

{Select the correct options below describing aspects of gonad development
|type="[]"}
- testis cortical and ovary medullary
+ ovary cortical and testis medullary
+ prenatal meiosis in the ovary germ cells
- prenatal meiosis in the testis germ cells
+ prenatal mitosis in the ovary germ cells

||Remember the anatomy of the adult gonads, with cortical primordial follicles in the ovary and medullary seminiferous tubules. The primordial germ cells in the testis form diploid spermatogonia that proliferate by mitosis and divide by meiosis postnatally. The primordial germ cells in the ovary form primordial oocytes that proliferate by mitosis and commence meiosis prenatally in the fetal ovary.
