  1. Follicle Stimulating Hormone (FSH)
  2. Graafian
  3. estrogen
  4. cervical mucus
  5. ovulation
26

27
Q

The follicle that reaches maturity is known as _____________

A

28
Q

Estrogen can be secreted by:

2. Corpus

29
Q

Estrogen can be secreted by:

A
  1. The Ovarian Follicle (second)

2. Corpus Luteum

30
Q

___________ LH is necessary for follicular growth and ovulation.

A

luteinizing hormone

31
Q

OVULATION

During the follicular phase, estrogen ______1___ production of luteinizing hormone (LH)

When the ovum has nearly matured, estrogen ___2_____ production of LH (positive feedback loop)

The release of LH causes the fully developed follicle to release its ____3____ oocyte

After being released from the ovary, the ovum is swept into the ________ tube

A
  1. suppresses
  2. stimulate
  3. secondary
  4. fallopian
32
Q

luteinizing Hormone is ______1_____ in the Follicular phase

while

luteinizing Hormone is ______2______ on the Ovulation Phase

A
  1. Suppressed

2. Stimulated

33
Q

LUTEAL PHASE

______1______ is a solid body formed in an ovary after the ovum has been released into the fallopian tube

Produces significant amounts of progesterone, which make ______2______ receptive to implantation of the blastocyst

High levels of Estrogen and Progesterone _____3_____ production of FSH and LH
Low levels of progesterone trigger menstruation and the beginning of the next cycle

A
  1. Corpus luteum
  2. endometrium
  3. suppress
34
Q

High levels of of Estrogen and Progesterone Suppress production of ____________ FSH and ____________ LH

A

Follicle Stimulating Hormone and luteinizing hormone

35
Q

___________ is a solid body formed in an ovary after the ovum has been released into the fallopian tube

A

Corpus luteum

36
Q

progesterone aid to :

  1. Maintain the __________ layer of the uterus
    and

2, makes the endometrium layer receptive to __________ of the blastocyst

A
  1. endometrium

37
Q

Low levels of _________ trigger menstruation and the beginning of the next cycle

Nb: this is because progesterone maintains the layer of the uterus thus low levels of it means the endometrium degrades and causing discharge of blood

A

progesterone

Nb: this is because progesterone maintains the layer of the uterus thus low levels of it means the endometrium degrades and causing discharge of blood
