What
is

-
ANSWER

initiation
of
milk
production
How
many
stages
of
Lactogensis
are
there?
-
ANSWER
4
What
stages
of
Lactogenesis
occur
during
pregnancy?
-
ANSWER
1
and
2
Lactogenesis
1
-
ANSWER
Ductal
and
Lobular-Alveolar
systems
grow
at
an
accelerated
rate
(influenced
by
hormones)
-
breasts
enlarge
-
high
progesterone
levels
cause
an
increase
in
alveoli
-
colostrum
begins
to
produce
in
the
alveoli
When
does
Lactogenesis
1
occur?
-
ANSWER
around
16
weeks
Lactogenesis
2
-
ANSWER
The
placenta
is
released
from
the
uterus
and
progesterone
levels
drop
-
this
causes
the
alveolar
cells
to
begin
to
release
milk
and
allows
them
to
continue
to
produce
more
milk
How
long
does
Lactogenesis
2
last?
-
ANSWER
2-4
days

-
ANSWER
-
Parenchyma:
ductal
and
lobular-alveolar
structures
-
Strom:
connective
tissue
(fat,
vascular,
nerve,
lymphatic)
What
is
an
Alveolus
-
ANSWER
Small
cavity
where
milk
is
produced
and
stored
-
made
of
epithelial
cells
What
are
Alveoli?
-
ANSWER
multiple
alveolus
What
is
the
Intra-lobular
duct?
-
ANSWER

a
lobule
to
the
lactiferous
ducts
What
is
a
Mammary
Lobule?
-
ANSWER
10-100
alveoli
combined
together
What
are
Lactiferous
Ducts?
-

Breast
Anatomy
-
ANSWER
What
surrounds
the
breast
tissue?
-
ANSWER
Fat
Nerves
Lymph
Tissue
Vascular
Network
Myoepithelial
Cells
What
is
the
purpose
of
the
Myoepithelial
cells?
-
ANSWER
They
surround
the
alveolus
and
contract
(like
a
muscle)
-
pushes
milk
out
into
the
ducts
What
is
the
purpose
of
the
Vascular
Network
surrounding
breast
tissue?
-
ANSWER
-
supplies
nutrients,
materials,
hormones
to
each
alveolus
for
milk
production
-
supplies
hormones
to
the
myoepithelial
cells
for
ejection
of
milk
