25
Primary male sex hormone responsible for the development of male secondary sexual characteristics.
Testosterone (Produced by the Testes)
26
What is the function of Follicle-Stimulating Hormone (FSH) in females?
1. Growth and development of ovarian follicles. 2. Works with Luteinizing Hormone (LH) to trigger ovulation 3. Helps regulate the menstrual cycle and promotes estrogen production
27
What is the function of Follicle-Stimulating Hormone (FSH) in males?
1. Stimulates the Sertoli cells in the testes to support sperm production 2. Works alongside Luteinizing Hormone, which stimulates testosterone production.
28
These are hormones produced by the pituitary gland that plays a crucial role in both the male and female reproductive systems.
Luteinizing Hormone (LH) Follicle-Stimulating Hormon (FSH) Prolactin (PRL)
29
What is the function of Luteinizing Hormone (LH) in males?
1. Stimulates the Leydig cells in the testes to produce testosterone, which is essential for sperm production 2. The development of male secondary sexual characteristics.
30
What is the function of Luteinizing Hormone (LH) in females?
1. Triggers ovulation 2. Stimulates the corpus luteum to produce progesterone, which helps prepare the uterus for pregnancy. 3. Works alongside Follicle-Stimulating Hormone (FSH) to regulate the menstrual cycle.
31
What are the two types of cycles that all females, who have reached puberty, go through?
1. Ovarian Cycle 2. Uterine Cycle
32
The series of natural changes that occurs in the uterus and in the ovary.
Menstrual Cycle
33
This is where an egg matures and is ovulated.
Menstrual Cycle
34
This is where change occurs to the Follicles in the Ovaries
Ovarian Cycle
35
What are the 3 Phases of Ovarian Cycle?
1. Follicular Phase (Day 1-13) 2. Ovulation Phase (Day 14) 3. Luteal Phase (Day 18-28)
36
FSH and LH cause the remaining parts of the Follicle to transform into?
Corpus Luteum
37
What is Corpus Luteum?
Yellow Hormone-secreting body in the female reproductive system.
38
This is where changes to the Endometrial lining occurs in the Uterus.
Uterine Cycle
39
What are the 3 Phases of the Uterine Cycle?
1. Menstruation Phase (Day 1-5) 2. Proliferative Phase (Day 6-14) 3. Secretory Phase (Day 15-28)
40
This is where the menses or menstrual blood is shed from the lining of the uterus, which is known as the Endometrium.
Menstruation Phase
41
What is the Endometrium?
The lining of the Uterus
42
This is where Estrogen causes the lining of the uterus to grow or profilerate.
Proliferative Phase
43
As the Corpus Luteum produces progesterone, this causes the Endometrium to become receptive to implantation of the developing zygote (Blastocyst) and supportive of early pregnancy.
Secretory Phase
44
It is marked after the release of the mature egg.
Luteal Phase
45
It is the shortest phase where the mature egg is released.
Ovulation Phase
46
It is when Ovarian Follicles mature and get ready.
Follicular Phase
47
A pair of female reproductive glands responsible for producing egg cells (ova) and secreting essential hormones.
Ovary Gland
48
A primary female sex hormone responsible for regulating the reproductive system and the development of secondary sexual characteristics.
Estrogen
49
A key female sex hormone that plays a crucial role in regulating the menstrual cycle, supporting pregnancy, and maintaining reproductive health.
Progesterone
50
A hormone produced by the pituitary gland that plays a key role in breast development, milk production (lactation), and reproductive health.
Prolactin (PRL)
51
What is the function of Prolactin (PRL) in females?
1. Stimulates milk production 2. Helps maintain breastfeeding 3. Can suppress ovulation
52
What is the function of Prolactin (PRL) in males?
1. Regulates testosterone levels and sperm production. 2. Influences sexual function and may affect libido.
53
What is the function of Prolactin (PRL) in both genders?
1. Plays a role in immune system regulation and metabolism. 2. Affects mood and behavior (linked to stress and bonding).
54
What does the Greek word, Homoios, mean?
Same
55
What does the Greek word, Stasis, mean?
Standing Still
56
What happens when a change in environment occurs?
It would send a signal to our body/system
57
It is responsible for the regulation and maintenance of the internal environment of the body.
Homeostasis
58
What is the Homeostasis Control Mechanism?
The body inhales oxygen, then it releases Co2
59
What are the Feedback Control Loops?
Sensor Mechanism Integrator/Control Center Effector Mechanism Feedback
60
These are the responses that trigger other activities or processes
Feedback Mechanisms
61
These reduce or minimize any changes of the body, bringing the conditions back to normal.
Negative Feedback
62
This allows your body to maintain its core internal temperature
Thermoregulation
63
The maintenance of constant osmotic pressure in fluids
Osmoregulation
64
This is the hormone that helps your kidneys manage the amount of water in your body
Antidiuretic Hormone
65
This is the maintenance of steady levels of glucose in the body
Glucoregulation
66
It is the sugar that comes from the foods
Blood Glucose
67
It is the hormone produced in the pancreas which regulates the amount of glucose in the blood.
Insulin
68
The shrinkage or contraction of a cell when it is exposed to the loss of water
Crenation
69
It is when a response increases Stimulus
Positive Feedback
70
The hormone released by the pituitary gland that causes increased contraction
Oxytocin
71
The rise in these hormones, along with Follicles.
The Menstrual Cycle
72
This releases chemical blood platelets
Blood Clotting
73
