BIOD 103 Mod 7 Remainder
Describe the contents of the scrotum and explain why the scrotum is outside of the
abdominal cavity. - answer The scrotum contains two testes with the epididymis. The
scrotum hangs outside of the body to control the temperature within the scrotum.
Sperm are not viable at body temperature and need to be at a lower temperature.
The ____ are the cells within the testes that produce sperm. - answer seminiferous
tubules
Describe the three columns of the penis. Which column contains the urethra? What is
another name for the head of the penis? - answerThe penis contains two columns,
called corpora cavernosa penis, and the third column, called the corpus spongiosum.
The corpus spongiosum contains the urethra. The head of the penis is also called the
glans penis.
List the path of sperm from where it is formed to outside the body, including the three
sections of the urethra. - answerTestes, epididymis, vas deferens, ejaculatory duct, and
then the urethra. The three sections of the urethra are the prostatic urethra, the
membranous urethra, and the penile urethra.
Describe the various structures that add to the seminal fluid prior to ejaculation. -
answerThe seminal vesicles secrete fluid that becomes part of the seminal fluid. The
bulbourethral gland and the prostate gland secrete mucus and fluid that also become
part of the seminal fluid.
The _(A)_ is the skin folds that cover the glans penis. It may be removed by a
procedure called _(B)_. - answerA) foreskin
B) circumcision
The _(A)_ are the primary female sex organs. They produce both _(B)_, the female sex
cell, and _(C)_ and _(D)_, the female sex hormones. - answerA) ovaries
B) the ova
C) estrogen
D) progesterone
Describe the sections of the uterus, the layers of the uterus, and the function of the
uterus. - answerThe sections of the uterus are the fundus, the body, and the cervix. The
layers of the uterus are the endometrium, myometrium, and perimetrium.
, The function of the uterus is to house the developing fetus during pregnancy. It also
functions to contract during childbirth to push the newborn out of the uterus.
Describe the structure and purpose of the fallopian tubes. Describe the function of the
vagina. - answerThe fallopian tubes have three sections: the infundibulum, the ampulla,
and the isthmus. The function of the fallopian tubes is to collect an ovum after it has
been released from the ovary and propel it towards the uterus.
Fertilization frequently occurs in the fallopian tubes. The function of the vagina is to
provide a way for menstrual fluid to leave the uterus, as well as serve as the birth canal
for the fetus during childbirth. The vagina also receives the penis during sexual
intercourse.
The external female genitalia is called the _(A)_. B) What are the sections of the female
genitalia? - answerA) the vulva
B) The sections of the vulva are the mons pubis, the labia majora and minora, the
vestibule, and the clitoris. The vestibule contains the external urinary meatus and the
ducts of the Bartholin glands.
Identify and describe the three phases of the menstrual cycle. - answerThe follicular
phase is first and this is when the endometrium is shed through the vagina. The
ovulatory phase is next. The levels of estrogen, FSH, and LH rise, which causes the
endometrium to thicken again and a follicle within the ovary to develop and then release
a mature egg. The final phase is the luteal phase.
The corpus luteum within the ovary secretes progesterone, and estrogen continues to
develop the endometrium. If the egg is not fertilized, these hormone levels will
decrease, and a new menstrual cycle will begin again.
How long is a typical pregnancy? What are the names of the three stages of human
development? Describe the three stages of labor. - answer40 weeks long
The three stages of human development are the preembryonic stage, the embryonic
stage, and the fetal stage. The first stage of labor is dilation of the cervix, the second
stage of labor is the birth of the baby, and the third stage of labor is the delivery of the
placenta.
The process of sperm formation occurs in the testicle, and they mature in the
epididymis. Identify the terms from the flashcards that correspond to the following
definitions.
a. Pertaining to the testicle.
b. Formation of sperm.
c. Inflammation of the epididymis. - answerA) Testicular.
B) Spermatogenesis.
