A mass of up to 32 undifferentiated cells is called a Ferti

A mass of up to ~32 undifferentiated cells is called a _______________________.

Fertilization typically occurs in the ______________.

The fast-block is one mechanism for ensuring _______________________.

The cavity in the blastocyst is called the ________________.

Enzymes from the __________________ “soften” the endometrium for implantation.

The last of the three germ layers to develop is the __________________.

During pregnancy, the __________________ maintains estrogen/progesterone levels.

Trophoblast cells secrete ______________ which maintains the corpus luteum.

A neural tube defect where only the meninges and cerebrospinal fluid escape is called spina bifida ____________________.

After implantation, a new cavity called the _______________________ develops in the inner mass cells.

Monospermy

Plancenta

Amnionic cavity

Ectoderm

Mesoderm

Endoderm

Blastocele

Human chorionic

        Gonadotropin (hCG)

Human placental lactogen

         (hPL)

Human Chorionic thytropin

         (hCT)

Trophoblast

Ampulla

Solution

A mass of up to ~32 undifferentiated cells is called a morula.

Fertilization typically occurs in the ampulla of the fallopian tube

The fast-block is one mechanism for ensuring monospermy.

The cavity in the blastocyst is called the blastocele.

Enzymes from the trophoblast “soften” the endometrium for implantation.

The last of the three germ layers to develop is the mesoderm

During pregnancy, the human chorionic Gonadotropin (hCG) secreted by trophoblast maintains estrogen/progesterone levels.

Trophoblast cells secrete human chorionic Gonadotropin (hCG) which maintains the corpus luteum.

A neural tube defect where only the meninges and cerebrospinal fluid escape is called spina bifida - Meningeocele

After implantation, a new cavity called the amnionic cavity develops in the inner mass cells.
