REPRODUCTIVE SYSTEM 01
Identify the genital ridge (5) in this 51/2 week embryo at the indifferent stage of gonadal development.
REPRODUCTIVE SYSTEM 02
This is the abdominal region from a 9 week old female fetus. Identify and describe the development of the following structures: bladder (2), genital tubercle (distal to #3), metanephros (4), suprarenal gland (9), ovary (6), rectum (7), round ligament of the uterus
(8), suspensory ligament of ovary (10), uterine tube (12), uterovaginal primordium (13).
REPRODUCTIVE SYSTEM 03
Enlarged view of 9 week female pelvis showing rectum (7), ovary with primordial follicles (6), round ligament of
uterus (8), uterine tube (12) and uterovaginal primordium (13).
REPRODUCTIVE SYSTEM 04
Identify and describe the development of the external genitalia in a 9 week female fetus: clitoris (3), labia majora (4), labia minora (5).
REPRODUCTIVE SYSTEM 05
Identify and describe the development of the external genitalia in a 9 week old male fetus: anus (1), labioscrotal
swelling (3), urethral folds, urethral groove (7), phallus (5).
REPRODUCTIVE SYSTEM 06
IDENTIFY the following in a ten week male fetus: labioscrotal swellings (2), genital folds (8), urethral groove (7),
glans penis (4), scrotal raphe (5), scrotum (6).
REPRODUCTIVE SYSTEM 07
This dissection of a 13 week male shows the body of the penis (6), the urethral meatus (12), the scrotal raphe (8), and the scrotum (9).
REPRODUCTIVE SYSTEM 08
Identify the following internal male organs: testes (7), bladder (2), rectum (5), ductus deferens.
REPRODUCTIVE SYSTEM 09
Explain embryological basis of hematocolpos
REPRODUCTIVE SYSTEM 10
Explain embryological basis for double uterus. Why is one side enlarged?
REPRODUCTIVE SYSTEM 11
Explain the embryological basis for double cervix.
REPRODUCTIVE SYSTEM 12
Explain the embryological basis for double vagina.
REPRODUCTIVE SYSTEM 13
What is a possible explanation for this condition known as micropenis?
REPRODUCTIVE SYSTEM 14
Recognize and describe the most likely cause of cryptorchidism.
REPRODUCTIVE SYSTEM 15
Identify a unilateral indirect hernia.
REPRODUCTIVE SYSTEM 16
Recognize and describe the embryological basis for hypospadias.
REPRODUCTIVE SYSTEM 17
This four year old genetic male is an example of 21-hydroxylase deficiency. Explain the hormonal basis for this
abnormality. (Review hormonal products of suprarenal gland and estrogen precursor dihydroepiandrosterone).
REPRODUCTIVE SYSTEM 18
Contrast the result of 21-hydroxylase deficiency in a genetic female with the same condition in the male.
REPRODUCTIVE SYSTEM 19
This is an example of ANDROGEN INSENSITIVITY SYNDROME. This individual is a genetic male with an absence of testosterone receptors on the normally responsive tissue. The abdominal scar is from bilateral
orchidectomy.
REPRODUCTIVE SYSTEM 20
This is the external genitalia of a male with testicular feminization. Note the oversized clitoris, labia majora fused
posteriorly and rudimentary vagina. The labia minora can also be identified.
