17
Q

This is known as the love hormone which helps us connect to others.

It is stored in the posterior pituitary gland

It stimulates uterine contractions during childbirth and helps to release milk from the milk ducks of nursing mothers

A

Oxytocin

18
Q

This hormone helps reabsorb water in the kidneys

It is the opposite of a diuretic and it brings in the water or fluid

A

anti- diuretic hormone

19
Q

This gland is about the size of a pea

It is located in the center of the brain

It produces what? which is stimulated by darkness and suppressed by light

It also helps regulate sleep cycles on a 24 hour basis

Timing and release a female very productive hormone is controlled by what?

A

Pineal gland

Melatonin

Melatonin

20
Q

This is a bow tie shaped gland located in the neck just below the voice box (larynx) and around the upper part of the windpipe (trachea)

A

Thyroid gland

21
Q

This is the hormone which affects nearly all the cells of he body by regulating their metabolic rates or the ability of cells to convert food to energy through cellular respiration

A

Thyroxine

22
Q

Occurs when the thyroid gland fails to produce enough thyroxine hormone.

Goiter - swelling of the thyroid in the neck

This is why we add iodine to table salt

A

Hypothyroidism

23
Q

This occurs when the third gland produces too much of the thyroid hormones

This can cause cretinism where the base of the skull is shortened in the face is light in short, the Mandible is under developed in the maxilla is over developed

A

Hyperthyroidism

24
Q

Located on the top of the thyroid gland

Secretes parathyroid hormone

Four small glands

Control calcium in bone growth, muscle tone , nervous system activity

A

Parathyroid gland

25
Q

This is a fish shaped gland located behind the stomach

It is considered to be a endocrine gland when it produces hormones and is also part of the digestive system when it produces digestive enzymes

Responsible for producing insulin

A

Pancreas’s

26
Q

When is insulin released?

What does it help in the body?

A

When the blood sugar (glucose) is high

Helps cells move glucose into the cells and helps the liver and muscle convert glucose to glycogen

Also helps convert excess glucose to fat, which is then stored

27
Q

This is released when the blood sugar is too low?

It helps to break down the glycogen in the liver and the muscles into glucose which then raises the blood glucose levels

A

Glucagon

28
Q

This is a lifelong disease that occurs when the pancreas does not produce enough insulin to regulate blood sugar’s

Without insulin what happens?

A

Type 1 diabetes

Glucose increases in bloodstream and increases hunger

29
Q

This is a lifelong disease marked by high levels of sugar in the blood in occurs when the body does not respond correctly to insulin.

Glucose cannot enter the body cells to be used in energy production and is the most common form of diabetes

A

Type 2 diabetes

30
Q

This type of diabetes occurs when the diabetes is first diagnosed during pregnancy, blood sugar is usually return to normal after delivery, they are at an increased risk of developing type two later in life

A

gestational diabetes

31
Q

These glands are two triangular shaped glands that sit on top of each kidney

A

Adrenal glands

32
Q

This is known as the stress hormone and is released during times of continuous stress.

It is released from the adrenal cortex which is the outer layer of the adrenal gland

It helps to control the rate of metabolism of carbohydrates fats and proteins

In negative aspect is that it suppresses the action of white blood cells which makes a person more susceptible to illness

A

Cortisol

33
Q

This is released from the adrenal medulla or the middle section

It makes up 80% of the secretions from adrenal medulla

It helps to regulate the stress (sympathetic )response for the fight or flight

A

Epinephrine (adrenaline)

34
Q

This is released from the adrenal medulla or middle section

Who makes up 20% of the secretions from the adrenal medulla

Along with adrenaline and helps to reverseThe stress (sympathetic) Response or the fight or flight.

A

No adrenaline (norepinephrine)

35
Q

What is the sympathetic symptoms in the body?

A

Increased heart rate, breathing rate, blood flow to the muscles, blood pressure, depth of breathing, oxygen intake, release of extra glucose for more energy, sweaty hands and palms

36
Q

What is the fight or flight response symptoms in the body?

A

Adrenaline released into the blood, heart rate and blood pressure increase, lower blood to brain increases, breathing rate increases, more sugar released into blood ability of blood clot increases, flow of blood to skin reduced and sweating increases, Flow of blood to digestive system reduced, digestion slows, more stomach acid produced, pupils wide open, muscle tense, More energy produced by cells, lump forms in throat as muscle contract

37
Q

Releases the hormone thymogen

Found under the sternum, the gland shrinks as you get older into adulthood

Helps with the development of anti-bodies in the immune system

A

Thymus gland

38
Q

Located on both sides of the uterus below the opening of the fallopian tubes

Produces estrogen and progesteroneWhich affect the female characteristics and reproductive functions

A

Ovaries

39
Q

Egg shaped organ that hang in a pouch of skin called the scrotum outside the male body.

They produce testosterone which affects males characteristics in the production of sperm

A

Testes

40
Q

S/S of Addison’s disease

A

Bronze pigmentation

Changes in distribution of body hair

Low blood sugar

Hunchback, weight loss, G.I. disturbances, weakness, fatigue, dehydration, decrease blood pressure, Reno shut down, decrease sodium, increase potassium

41
Q

Signs and symptoms of Cushing’s syndrome

A

Personality changes, moon phase, high blood sugar, CNS irritability, increase infections, gynecomastia , Then extremities, sodium and fluid retention (edema), Fat deposits on face and back of shoulders, G.I. distress due to the increase in acid, osteoporosis, thin skin, purple stray, bruises and petechiae, females-amenorrhea, hirsutism
