Answer to the inhibtion test:

1.TGF (Transforming Growth Hormone)
2.
Bone morphogenetic proteins
3.Transforming Growth Hormone)
4.Activin
5.Inhibin
6.Polypeptide hormones
7.
Bone morphogenetic proteins
8.Osteogenesis
9.Two ( A and B)
10.Inhibition

iNhibition Questions.

1. These are proteins secreted by transformed cells that can stimulate growth of normal cells?
2.These are non-collagenous factors and they arebelieved to be proteins that occur in demineralised bone and stimulate osteogenesis.
3.Transcribe TGF.
4. It regulates the morphogenesis of branching organs such as the prostate, lung, and especially kidney?
5.
IT inhibits FSH production and GnRh release from the hypothalamus. However, the overall mechanism differs between the genders:
6. They secreted by the hypophysis that selectively suppresses the secretion of pituitary follicle stimulating hormone.
7.Transcribe BMP
8. It is the process of laying down new bone material by osteoblasts.
9.How many molecule does polypatide hormone have?
10.It is the process in suppressing or reducing hormones mechanism?

Reaction ON Drug Testing

DO YOU AGREE THAT DRUG TESTING SHOULD BE DONE AS A REQUIREMENT FOR ADMISSION TO SCHOOL? Why OR Why not?

I totally agree on this matter because as a student we must know what drugs can do to our body. Even if the students are totally addicted to a certain drugs through this drug test it allows the authority to know if the students are positive in taking drugs. Not only this, it also serves as an indicator for the school to know if the students that they admit are all negative and not the vice-versa. This can also be a screening test whether they will admit the students or not. If the student is confirmed to be a positive user of a certain drugs the school can also be the one who can administer a possible solution on this student’s addiction. I do also suggest that not only the students should do this but also all the employee who are working on this school should also do drug testing.

As a student I strongly believe that the school is our second home. Like our parents they are concerned on what are going in our life. Whether we are on right or destructive path… for the benefits of other students and also us we must all agree that this specific test must be one of the requirements in entering a certain university. Thank you!!!

inhibition test

Polypeptide hormone secreted by the hypophysis that selectively suppresses the secretion of pituitary follicle stimulating hormone. The molecule has two subunit and is a product of the gene family that includes TGF . There are two forms, A and B, the subunit being shared with activin.

Things To Learn:

TGF (Transforming Growth Hormone)- these are proteins secreted by transformed cells that can stimulate growth of normal cells.


Bone morphogenetic proteins – these are non-collagenous factors and they arebelieved to be proteins that occur in demineralised bone and stimulate osteogenesis.

Adenohypophysis

For many years,
Anterior Pituitary Gland or Adenohypophysis
Consists of two parts
The pars distalis
And the pars tuberalis

It secretes hormones that regulate body activities
From growth to reproduction
Stimulated by releasing hormone
And suppressed by Inhibition

Five types of pituitary cells are seen
On the anterior division they have been
They secrete seven hormones respectively
To maintain the balance of humanity

HGH or Human Growth Hormone
Secreted by Somatotrophs that is mainly responsible
For the secretion of insulin growth factor
To enhance body growth stimulation
A X- factor on the circulation

Gonadotrophs secrete two hormones
The follicle and luteinizing hormones
They both act on the gonads
To stimulate estrogen and progesterone
On the maturation of oocytes they are responsible
To stimulate sperm production
And secretion of testosterone

Lactotrophs secrete prolactin
That promotes milk secretion
By the mammary gland that is a hero
Without this woman's breast
They are sure zero


Adrenocorticotropic secreted mainly
To control the production of cortisol completely
And glucocorticoids in the outer portion of the adrenal gland
We proudly say that Corticotrophs is the "MAN"

Lastly for the final promotion
I introduce to you Mr. Thyrotrophs
It is the professional and only hope
To stimulate synthesis of T3 and T4 in the thyroid.


Now you have to know Anterior Pituitary clearly
On this little poem written by a student in CC
Now it is time for a farewell
To the five little anterior cells - soldier
I hope that will be a big help in our course
And to this five little cells
Let's give them a round of applause

questions about anterior pituitary gland+(the Answers)

1. What hormones are released by the anterior pituitary gland?

Adrenocorticotropic hormone, thyroid hormone, growth hormone, prolactin, luteinizing hormone, follicle stimulating hormone

2. How does the hypothalamus control both anterior and posterior pituitary functioning?

The two pituitary lobes are the dual origin of the hypothalmus. The posterior pituitary lobe is part of the brain and is a "downgrowth" of hypothalmic tissue and maintains a neural connection with the hypothalmus through a nerve bundle called the hypothalamic-hypophyseal tract. This arises from neurons of the hypothalmus. These cells synthesize two neurohormones and transport them along their axons to the posterior pituitary. Then these neurons "fire" they release the stored hormones into a capillary bed in the posterioir pituitary for distribution throughout the body.

3. What lies directly above the pituitary gland?

the hypothalamus


4. The pituitary gland rests in a depression of the base of the skull, which is called the _________?

sella turcica

5. Blood from the pituitary drains into what vein?

hypophyseal portal vein

6. Why is the pituitary gland referred to as the master gland in the human body?


Because it regulates all the hormones that cause the other organs to work.

7. What is the hormones responsible for sex hormones reproduction?

Luteinizing hormone

8. Hormone responsible for milk production?

prolactin

9. Hormone that secrete thyroid hormones?

thyroid stimulating hormone

10. Hormone that secretes Glucocorticoid?

Adrenocorticotropic hormone

Case Analysis

A female 44 yrs old - for the last 3 years she have suffered a progression of symptoms from hair loss, dry skin, fatigue, dizziness, constipation, erratic heavy periods, muscle aches & pains, foggy head, memory failure. She have seen endless doctors & specialists - mainly at her own expense - because she would not accept their diagnosis that she was depressed or it was simply her age! Her thyroid blood tests are all within the normal range. But after the consultaion with her Doctor she found out the she was a Hypothyrodism.

1.What is the recommended test to be taken to know if she is actually a Hypothyrodism?
2. If all of her blood tests are all within normal does it means that she don't have the disease?
3.Is there are possible treatment for this kind of disease? if yes, what are they?

A major organ of the endocrine system, the anterior pituitary, also called the adenohypophysis, is the glandular, anterior lobe of the pituitary gland. The anterior pituitary regulates several physiological processes including stress, growth, and reproduction.
Its regulatory functions are achieved through the secretion of various peptide hormones that act on target organs including the adrenal gland, liver, bone, thyroid gland, and gonads. The anterior pituitary itself is regulated by the hypothalamus and by negative feedback from these target organs.

The anterior pituitary is composed of multiple parts:
The pars distalis, or "distal part", comprises the majority of the anterior pituitary and is where the bulk of pituitary hormone production occurs. Occasionally, "pars distalis" is incorrectly used as a synonym for the anterior pituitary.
Pars tuberalis

The pars tuberalis or "tubular part", forms a sheath extending up from the pars distalis and wrapping around the pituitary stalk. Its function is poorly understood.
Pars intermedia
The pars intermedia, or "intermediate part", sits between the pars distalis and the posterior pituitary and is often very small in humans

Major Hormones Secreted by Anterior Pituitary Gland
Adrenocorticotropic hormone- Secretion of glucocorticoids
Thyroid-stimulating hormone- Secretion of thyroid hormones
Follicle-stimulating hormone- Growth of reproductive system
Luteinizing hormone- Sex hormone production
Growth hormone- Promotes growth; lipid and carbohydratemetabolism
Prolactin- Secretion of estrogens/progesterone; milk production
