Discuss the supportive cells of the blastocyst and their
purpose during pregnancy.
(The amnion, placenta and umbilical cord.) The amnion
forms a sac filled with fluid to cushion and protect the
fetus. The placenta is a temporary organ that carries out
nutritive, respiratory, excretory and endocrine functions
for the embryo. The baby continues to grow in the uterus
with nutrition provided by the placenta for nine months
until it is time for delivery. The umbilical cord attaches the
embryo to the placenta.
Label each of the following as occurring during the: 1st
trimester, 2nd trimester or 3rd trimester
1. Lungs fully mature: 3rd trimester
2. Lanugo develops: 2nd trimester
, 3. First fetal movements felt: 2nd trimester
4. Neurulation: 1st trimester
5. Testes descend to scrotum: 3rd trimester
Find the steps that correctly order neurulation:
A. Ectoderm→ neural crest → convergence → neural groove
→ brain
B. Endoderm→ neural groove → convergence → neural tube
and neural crest
Correct! C. Ectoderm→ convergence→ neural fold → neural
tube → spinal cord
D. Endoderm→ convergence→ neural crest → neural groove
→ spinal cord
Name and discuss the stage of labor that best describes
the figure below:
The first stage, dilation of the cervix, is the time it takes for
the mother’s cervix to dilate to ten centimeters. During this
stage the uterus contracts, which pushes the baby’s head
against the cervix causing it to dilate (widen). This stage of
labor is the longest, lasting, on average 6-10 hours.
Oxytocin is a hormone that is released from the posterior
pituitary gland to stimulate contractions in the
myometrium of the uterus. As contractions continue,
oxytocin is increasingly released until the baby is born.
All the following are functions of the ovaries EXCEPT:
