Epididymis & Ductus deferens
The single cell produces by fertilization is referred to as a/an __________
Zygote
The male urethra is surrounded by the erectile tissue known as the
Corpus spongiosum
The hormone associated with labor contractions, milk letdown reflex, and bonding
Oxytocin
The hormone ___________ increase the elasticity of the symphysis pubic joint and pelvic ligaments to make room for growing fetus, allowing expansion of the pelvic outlet for childbirth. It also helps dilate the cervix during labor
Relaxin
The head of the sperm is covered by a cap-like structure called the _______; it is filled with lysosomal enzymes important for preparing sperm to participate in fertilization
Acrosome
The finger-like projection called fimbriae, at the distal end of the uterine tubes, are part of the
Infundibulum
The event which triggers ovulation is
An LH surge
The embryo develops from the
Inner cell mass
The digestive enzymes released from the ___________ of the sperm digest the extracellular matrix of the surrounding the oocyte
Acrosome
The condition in which an erection does no subside within a normal amount of time is known as
Priapism
The cells lining the seminiferous tubules, to which immature sperm are attached, are called:
Sertoli cells
Shelia had a miscarriage and lost the pregnancy around week 5. Her obstetrician told her that, based on the ultrasound, it could not have made it to term because it had implanted in the uterine horn, a condition known as
Ectopic pregnancy
Most traits in people are influenced by more than one set of genes, and are therefore referred to as being [x].
Polygenic
Formerly known as Leydig cells, cells secrete testosterone, increasing production at puberty to initiate male sexual characteristics
Interstitial
Gonadocorticoids: (choose 2)
- Are produced in the adrenal cortex
- Cause development of secondary sec characteristics
The case of complete dominance, for a recessive gene to be expressed in the phenotype, you would have to be ________________ for that gene
Homozygous
Jo inherited a gene for blue eyes from her dad and a gene for brown eyes from her mom. You would say she is ______________ for her eye color genes
Heterozygous
In _____________, the offspring express a heterozygous phenotype that is intermediate between one parent’s homozygous dominant trait and the other parent’s homozygous recessive trait. For example, red X white = pink
Incomplete dominance
Mid-menstrual cycle, _____________ makes the end of the proliferative phase and the start of the secretory phase of endometrial development
Ovulation
Cryptorchidism is the clinical term used when
At least one testicle does not descend into the scrotum
Cells to which developing sperm are attached during production during known as
Sustentacular cells
Approximately 3 days after fertilization, the free floating 16-cell conceptus reaches the uterus. It is now a solid ball of cells referred to as a
Morula
Male pattern baldness is inherited from the mom’s side of the family. Bob wanted to know the chances that he would lose most of his hair after he aged, so he had to look at his maternal grandfather to get an idea. This type of inheritance is an example of a/an ____________ trait.
X-linked recessive
A developing human is referred to as an embryo
Up through 8 weeks
A common form of permanent birth control for men involves severing the
Ductus deferens
A follicle that fails to develop but instead regresses is said to be undergoing
Atresia
A male erection is produced by which tissue?
Corpus cavernosum
A pap smear looks at cells taken from the ________
Cervix
Contains cilia in the male
Ductus deferens
Fertilization takes place usually at the junction of the isthmus and
Ampullae
In early pregnancy, the corpus luteum is not lost due to the presence of ___________, produced by the zygote
HCG
In the male, peristalsis propels sperm through the
Ductus deferns
Male and female sexual arousal is under the control of the
Parasympatheic system
Prior to ovulation, female sexual desire is increased by the rising levels of

The beginning of the menstrual cycle is marked by
The period/menstruation
The gamete that completes meiosis only after fertilization is the
Oocyte
The gubernanculum testis plays a role in
Testicle descent
The hormone often used to detect pregnancies
HCG
The hormone that keeps the uterine smooth muscle is relaxed during pregnancy
Progesterone
The male begins sperm production __________, while the female starts egg production __________.
At puberty/before birth
The midpiece of a sperm consists of
Mitochondria
The parietal tunica vaginalis lines the
Scrotum
The “period” is also referred to as
Menses
The secretory phase of the endometrial functional zone as it gets ready for possible implantation is primarily under the influence of
Progestore
