Make sure you pay attention to the bolded green words throughout the presentation because they are vocabulary words that will then help you later on……hint.. hint
To warn you guys there are some pictures that are really bad

SLIDE 2
•Body Process can happen slowly such as cell growth or fast such as breathing and body movements.
•Hormones: the body’s chemical messengers, that transfer information and instructions from one set of cells to another.
•Glands: Is a group of cells that secretes, or gives off chemicals; so the glands selects and removes material from the bloodstream and processes them to be used somewhere else in the body
•The foundations of the endocrine systems are:
Hormones
Glands

SLIDE 3
Nervous System: Monitors the environment; so when aberrations are detected the NS sends messages to the endocrine glands in which they would produce and secrete hormones into the blood
The hormone will then hit the target organ and produces the substances that the organ produces and then the receptors will pick up the activity and the brain stops sending messages to the endocrine glands
–Embryonic development and preparation for a newborn
–Influence sexual behavior;
stimulates growth and maturation of the gonads
–Feedback to the nervous system

Lies in the cranial cavity, in a small depression of the sphenoid bone that is in the sella turcica which looks like a saddle
Considered the Master Gland because-----Since the pituitary glands has tropic hormones meaning that it stimulates other endocrine glands to grow and produce their hormones -----It exerts this control over the thyroid gland, the adrenal cortex, the ovarian follicles, and the corpus luteum

SLIDE 7
The difference between the two glands is the prefix because adeno means gland and neuro means nervous
Explain the picture and point out where the anterior and posterior pituitary gland is

Considered the Master Gland because-----Since the pituitary glands has tropic hormones meaning that it stimulates other endocrine glands to grow and produce their hormones -----It exerts this control over the thyroid gland, the adrenal cortex, the ovarian follicles, and the corpus luteum
Adrenocorticotropic Hormone (ACTH)
•Acts on the adrenal cortex to increase in size and to secrete larger amounts of hormones called the cortisol - Hydrocortisone)
LH– Acts with FSH to perform several functions
Ovulating Hormone
The males pituitary glands also secrete LH -Has the same functions of FSH
For males the hormone was called the Interstitial Cell-Stimulating Hormone because it stimulates interstitial cells in the testes to develop and secrete testosterone, the male sex hormone

SLIDE 9
FSH– Stimulates maturation of ovarian follicle and ovum
Stimulates follicle cells to secrete estrogens and triggers ovulation
In males, it stimulates the somniferous tubules to grow and to form sperm
That is to the point of ovulation
Corpus Luteum– means yellow body in Latin …. It is what is left the follicle after a women's ovulates

GH---another name for growth hormone is somatotropion
–Speeds up the movement of digested proteins out of the blood into the cells It accelerates anabolism of amino acids to form protein tissues
Anabolism---to build up
GH– This hence normal growth
Affects fats and carbohydrates metabolism
Metabolism---a process which the food is used by a living organism…so in other words it is the break down of food that is absorbed by the cells in the body
–It accelerates fat catabolism and slows down glucose catabolism
Catabolism--- the breakdown of food compounds
Meaning that less glucose is leaving the blood to enter the cells, therefore the amount of glucose in the blood increases
GH and insulin has opposites effects on blood glucose
Insulin decreases blood glucose and GH increases it
Hypo---- is when there is too much insulin in the blood
Hyper---- is when there is too much growth hormone in the blood

After TSH---These hormones are other hormones that the pituitary gland secretes
–TSH-- Acts on the thyroid gland to increase the secretion of the thyroid gland
MSH---melanin---what gives our skin the color…it’s the brown skin pigment
Or called the lactogenic hormone
MSH--- Causes a rapid increase in synthesis and dispersion of melanin granules in specialized skin cells
–
Prolactine --- During pregnancy, Prolactin stimulates the breast development necessary for lactation
Lactation--- milk secretion of the breast
Meaning that it prepares for lactation so when the mother gives birth to the baby
Then after the baby is born the mother has the function to secretes milk from her breast

Releases two hormones
ADH--- With more water leaving the tubules into the blood, less water remains in the tubules, therefore less urine leaves the body
Anti– means against
Diuretic– means increasing the volume of urine excreted
So it means acting against an increases in urine volume
Accelerates the reabsorption of water from urine in the kidney tubules in the back in the blood
Oxytocin--- is secreted by a woman’s body before and after she has a baby
This is why physicians prescribe Oxytocin injections -----to induce or increase labor
Stimulates contraction of the smooth muscle of the pregnant uterus and is to initiate and maintain labor

Now I am going to explain some diseases and disorders of the Pituitary gland
Is when a child grow to a giant size… a person with a tall stature
Causes: Results from excess Somatotropion
prior to puberty and
fusion in the epiphyses
What is Somatotropion?
Epiphyses is the end of a long bone so it increases the length of the bone size

SLIDE 14
A person with a short stature… small body size…..it also deals with the GH
The releasing of the hormone can affect other pituitary cells that can result in multiple deficits
Causes:
By a tumor
Genetic factor
Injury
If diagnosed early, Can have GH injections
The GH injections can last at least up to 5 years or when the bone growth is fully developed

The effectiveness of insulin metabolism can result in diabetes
Gives you a grotesque appearance
You can develop slurred speech

A low level of ADH prevents water from being reabsorbed by the kidneys
Polyuria--- excessive urination
Polydipsia--- excessive thirst
ADH--- remember it helps take out the glucose from your urine and put’s it back into your bloodstream

SLIDE 17
Hypopituitarism--- is when the pituitary gland does not produce normal amounts of it’s hormones
If caused by a tumor you can have it surgically removed
It is not preventable
