The document discusses various topics related to hormones and their functions in the human body. It defines growth hormone and the condition of gigantism caused by its overproduction. It also discusses hormones involved in the fight-or-flight response like adrenaline and cortisol.

2.  Growth Hormone (GH) – a hormone that is
produced by the pituitary gland and stimulates
growth
 Gigantism - a rare condition that causes over
production of growth hormone

3.  Hypogeusia – reduced ability to taste things
which can be caused by viral infection,
traumatic brain injury, liver disease, etc.
 Ageusia – loss of the taste function of tongue

4.  Hyperacusis – sound sensitivity caused by head
injury, viral infection, etc.
 Tinnitus – consciously hearing a high-pitched
sound

5.  The hormone responsible for facial hair
growth is testosterone

6.  The fight-or-flight response is triggered by
the release of hormones that prepare your
body to either stay and deal with a threat
or to run away to safety
 Adrenaline and Cortisol

7.  Eye color is determined by variations in
a person’s genes

8.  Milk Allergy – abnormal response of immune
system to milk
 Lactose Intolerance – a condition where a
person lacks the enzyme lactase to metabolize
the lactose (milk sugar) in the intestine

9.  Fight-or-Flight Response
 Adrenaline – produced in the body when we
detect danger or when we are mad

10.  Endorphins – relieve stress and
pain
 Serotonin, Dopamine, Oxytocine –
the body’s happy hormones

11.  Fight-or-Flight Response
 Adrenaline and Noradrenaline

12.  Thyroid Gland – controls metabolism
• Underactive thyroid – tiredness, memory problems, and
depression
• Overactive thyroid – restless, anxious, and problem with
sleeping
 Estrogen, Progesterone, Testosterone, and Cortisol

13.  Serotonin – feeling sleepy after eating
 A person feels tired after eating because
their body is producing more serotonin.

14.  Reading speed is determined by a number
of factors, including a reader's purpose and
level of expertise as well as the relative
difficulty of the text.

15.  Growth Hormone (GH) – acts on many parts of
the body to promote growth
 Once the growth plates in the bones
(epiphyses) have fused, growth hormone will
not increase the height anymore.

16.  Fight-or-Fight Response
 Adrenaline and Noradrenaline

17.  Testosterone – causes the thickening of vocal
chords, which will result in a more male-sounding
voice.
 The female voice evolves from childhood to
menopause, under the varied influences of
estrogens, progesterone, and testosterone.

18.  Identical twins or triplets happen when a single egg is
fertilized and then later splits. These newly divided
embryos are identical.
 Fraternal multiples develop from separate eggs that
are fertilized by a different sperm.

19.  Food enters the mouth and is chewed. The
tongue moves the chewed food to the back of
the throat. The food is then swallowed.

20.  Melatonin – a hormone primarily released by
the pineal gland at night
 Being around too much bright light before bed
can affect our sleep as it can stop the release of
melatonin
