ANEQ 310: Animal Reproduction
Review Assignment 1
1. Define the following terms:
a. Rathke’s pouch
i. Pouch-An invagination of the stomodeum in the developing embryo that
gives rise to the anterior lobe of the pituitary.
b. Neurohypophysis
i. the posterior lobe of the pituitary gland
c. Infundibulum
i. a hollow funnel-shaped structure or passage
d. Diverticulum
i. a blind tube, or out pocketing that diverts from tubular organ or cavity.
e. Inguinal hernia
i. an abnormal condition where abdominal contents pass through the
inguinal canal and enter the vaginal canal
f. Mesonephric duct
i. the ducts that provide an outlet for the fluid produced by the
mesonephros in the developing embryo. They will be retained and form
the epididymis and the ductus deferens in the male or will become
vestigial in the female.
g. Medulla
i. lowest part of the brain stems and connects the brain to the spinal cord
h. Paramesonephric duct
i. ducts that originate lateral to the mesonephric duct in the female
embryo. They develop into the oviducts, cervix, uterus, and portions of
the cranial vagina.
i. Dihydrotestosterone
i. a hormone that plays a key role in the sexual development and
maintenance of male sex characteristics
j. SRY protein
i. Sex-Determining Region Y Protein is a DNA-Binding protein that initiates
male sex determination in mammals
k. AMH
i. Anti-Müllerian hormone a hormone that plays a key role in sexual
differentiation and ovarian function.
2. Describe the origin of the pituitary gland? Compare and contrast the anterior and
pituitary portions.
a. The ectoderm of the oral cavity is where the anterior pituitary gland is developed
and is from a structure called the Rathke's Pouch. Whereas the neural ectoderm
of the diencephalon in the brain is where the posterior pituitary gland originates
from.
