Distinguish between:
NOTOCHORD
and
NEURAL TUBE
Spermatogenesis – Production of the
sperm in the male. Germ cells give
rise to primary spermatocytes. These
spermatocytes go through meiosis (I
and II) to form four sperm cells. In the
mammalian testes, this occurs in the
seminiferous tubules. ______
released by the Anterior pituitary can
lead to spermatogenesis.
Parthenogenesis– The production of
a new organism from an ___________
egg. Ex. Ants, bees, wasps, whiptail
lizard.
Corpus Luteum– The structure
formed from the follicle cells after the
egg is released at ovulation. This
structure of follicle cells stays behind
in the ovary and releases __________
and ______________ to help maintain
uterine lining. If pregnancy doesn't
occur, the corpus luteum will stop
producing these hormones and the
uterine lining with slough off.
Testosterone – Male hormone
produced by the _________ cells in
the testes. It causes the development
of secondary sexual characteristics in
the male. It is also necessary for
proper production of sperm.
Acrosomal Reaction – When a
sperm reaches the egg, the acrosomal
membrane at the head of the sperm
breaks down and release _________
that digest a path through the outer
protective coat of the egg. The
acrosome process then grows from
the head of the sperm to fuse with the
egg membrane.
Oogenesis– Production of eggs in the
Gastrulation – During this stage of
embryonic development, cells
_______ to form the 3 tissue layers
(endoderm, mesoderm, and
ectoderm). The ______________ that
forms will become either the anus or
the mouth.
Cleavage – Rapid ______________
following the fertilization of an egg with
a sperm. There isn’t much time for
cell growth between divisions, so the
cells get smaller with each division
cycle.
Luteinizing Hormone (in male) –
Released by Anterior pituitary and
causes _________ cells to release
testosterone.
Luteinizing Hormone (in female) Released by Anterior pituitary and
triggers the mature follicle to release
its egg (ovulation) and the leftover
follicle cells to develop into the
_______________.
Neurulation - The initiation of the
_______________ system. The
ectoderm above the notochord
thickens and folds in on itself to create
the neural tube. The neural tube will
become the spinal cord and
___________.
Blastocyst – A ____________ ball of
32 cells that marks the end of
blastulation. Cells in the blastocyst
are totipotent (“stem cells” that have
the ability to become any type of body
cell. outer layer = form the placenta,
inner layer = forms embryo. This is
when the embryo implants into the
uterus.
Estrogen – Causes development of
secondary sexual characteristics in
females. Stimulates thickening of
uterine lining (called the
______________).
Endoderm – The inner most germ layer.
Will become the _______________ and
respiratory systems.
Mesoderm – The middle germ layer. It will
become the skeleton, muscles, circulatory
system, _______________ system and
most of the _________________ system.
Ectoderm – The outer-most germ layer.
Will become skin, hair, nails, sweat and oil
glands and the _______________ system.
Follicle Stimulating Hormone (in
male) - Stimulates spermatogenesis.
Notochord – _____________ that
becomes the vertebrae that protect the
spinal cord
Follicle Stimulating Hormone (in
female) - Helps follicles to mature in
ovary. Also stimulates production of
estrogen and progesterone in the
ovary.
Neural Tube – ____________ that will
become the spinal cord and brain.
Formed from neurulation.
female. Germ cells give rise to primary
oocytes. These oocytes arrest in Prophase
I of the Meiosis ___ until Puberty. Then
each month, an egg will complete Meiosis I
and then enters Meiosis II (which is then
only completed after fertilization by the
sperm. Oogenesis results in _________
cell division so that only one egg is made
with 3 small polar bodies left.
Progesterone - Causes development
of secondary sexual characteristics in
females. Maintains _____________).
