Q

Fucntions of the mucosal lining of the cervix

A
  • lubricates the vagina
  • acts as a bacteriostatic agent
  • provides an alkaline environment to shelter deposited sperm from the acidic pH of the vagina
  • produces mucous plug in the cervical canal during preg.

Q

4 sections of the Fallopian tubes

Study These Flashcards
A
  • Interstitial Portion (pt that lies in uterus)
  • Isthmus (narrow area near the uterus)
  • Ampulla (wider area, site of fertilization)
  • Infundibulum (Funnel, distal end)
17
Q

Functions of the Fallopian Tube

Study These Flashcards
A
  • passage way where sperm meets ovum
  • site of fertilization (1/3 of the tube)
  • safe nourishing environment for zygote
  • means of transporting the zygote to the corpus of uterus
18
Q

Function of Ovaries

Study These Flashcards
A
  • Steroid hormone prod: Estrogen, Progesterone
  • Ovulation (stimulation of an ovum maturation)
  • At birth, female has all the ova that will be available to her during her lifetime
19
Q

Important Pelvic Landmarks

Study These Flashcards
A
  • Ilium
  • Sacrum
  • Coccyx
  • Symphysis Pubis
  • Ischial spines
20
Q

Functions of the Pelvis

Study These Flashcards
A
  • Protective cradle for pelvic structures
  • Accommodates the growing fetus and forms birth passageway
  • Serves as an anchor for the attachment of the supportive muscles, fascia, and ligaments and distributes body weight
21
Q

Pelvic Shapes

Study These Flashcards
A
  • Gynecoid
  • Android
  • Anthropoid
  • Platypelloid
22
Q

Gynecoid (Pelvic Shape)

Study These Flashcards
A
  • Classic female pelvis (approx 50% of women)
  • Rounded anterior and posterior segments
  • Most favorable for vaginal birth
23
Q

Android (Pelvic Shape)

Study These Flashcards
A
  • Wedged shaped inlet (approx. 25% of women)
  • Narrow anterior segment
  • Oval in shape
  • Typical of male anatomy
24
Q

Anthropoid (Pelvic Shape)

Study These Flashcards
A
  • Anterior/Posterior diameter equals or exceeds its transverse diameter
  • A long narrow oval shape (24% of women)
  • Vaginal birth possible but likely in occipital position
25
Platypelloid (Pelvic Shape)
- Shortened anterior/posterior diameter (3% of women) - Flat, transverse oval shape - Unfavorable for vaginal birth
26
3 cycles of Menstration
- Hypothalamus-Pituitary Cycle - Ovarian Cycle - Endometrial Cycle
27
Conception
The union of the egg and sperm- beginning of pregnancy
28
Basic Genetics
- An egg contains 23 chromosomes (XX) - A sperm contains 23 chromosomes (XY) - Implantation/Nidation: occurs 7-10 days after fertilization
29
Fertilization
- takes place in the ampulla of the fallopian tube - when sperm enters ovum the cell formed is called a zygote - during transport through the fallopian tubes, the zygote does not increase in size, but undergoes a mitotic division (Cleavage) - Starts with 2 cell division>4>8 - Once the zygote reaches a 16 cell division = Morula - the morula enters the uterus on the 3rd day and floats for 2-4 days before implanting in the fundal section of the anterior or posterior uterine wall.
30
Chorion
- develops from Trophoblast - envelops amnion, embryo and yolk sac - thick membrane has projections called VILLI - villi extend into decidua basalis (endometrial layer once fertilized) - form the embryonic/fetal portion of placenta
31
Amnion
- second inner membrane - developed from the Blastocyst - covers the umbilical cord and covers the chorion on the fetal side - thin structure that envelops and protects embryo - together, the chorion and amnion form an amniotic sac filled which eventually fills with fluid
32
Yolk Sac
- a cavity develops on the 9th day after fertilization - functions only during embryonic life - initiates production of RBC - continues until fetal liver takes over about 6 wks - umbilical cord encompasses yolk sac which then degenerates
33
Germ Layers
after implantation the zygote in the blastocyst stage transform its embryonic disc into 3 primary germ layers known as: - Ectoderm - Mesoderm - Endoderm
34
Lanugo
Baby's first hair
35
Vernix
Cheese like covering to protect skin in A. fluid
36
Placenta
It's a temporary organ fo fetal respiration, nutrition, and excretion
37
Zygote
when the sperm enters the ovum the cell formed is called the zygote (the returning of the total number of 46 chromosomes)
38
Zygote stage
grows and develops until it passes through the Fallopian tubes and implants into the wall of the uterus (up until week two)
