Q

What is the difference between non target, target, tropic and non-tropic

A

Target means its targeting a specfic area, no target means its going to all cells, tropic means that it is targeting another endocrine gland that will release another hormone due to stimulation form the orignal hormone. non tropic means it doent release another hormone after this

Q

What is the difference between positive feedback and negative feedback

A

positive feedback is continious increasing of the product

negative feedback decreases and increases as needed - the product inhibits the production of the hormone when there is too much product.

-Hypersecretion?
- draw its negative feedback loop

A
  • thyroid

  • lowers blood calcium levels by increasing movement of calium from blood to bones
  • Hyposecretion: high blood calcium levels
  • Hypersectrion: Low blood calcium levels
24

- function?
- Hyposecretion?
-Hypersecretion?
- draw its negative feedback loop

A
  • Thyroid
  • non target - most cells - and non tropic
  • manges the bodys metablosim by increasing the rate of metabolism by speeding up cellular respiration and increases glucose usage and oxygen consumption
  • Hyposecretion: Crentenism and Myxedema
  • Hypersecretion: graves disease, protruding eyes
25
Parathyroid - Where is it relased from? - tropic? - target? - function? - Hyposecretion? -Hypersecretion? - draw its negative feedback loop
- parathyroid - node son the thyroid - target and non tropic - targest the blood, bones, kidneys and small intestine - increases blood calcium levsl by increasing the release of calium from bones to blood and increasing calcium reabsorption by the kidneys and small intestine
26
Aldosterone - Where is it relased from? - tropic? - target? - function? - Hyposecretion? -Hypersecretion? - draw its negative feedback loop
- Adrenal cortex - targets the kidneys - non tropic - raises blood pressure by increasing sodium reabsorbtion. - Hyposecretion: low sodium levels and low blood pressure - Hypersecretion: high sodium levels and high blood pressure

35
What are the types of diabetes mellitus
Type 1 : Autoimmune disorder where the body cannot produce enough insulin Type 2: Body may resist the effects of insulin or not produce enough according to your diet Gestational: When a woman has high blood glucose levels during pregnancy
36
Describe Diabetes Insipudis
When you body struggles with water retention by not producing enough adh or the kidneys stop responding to it - it makes you feel thirtsy even when youre not and you will produce large amounts of urine
37
What thes difference and similarity between adh and aldosterone
adh is for water retantion and aldosterone is for sodium retention, they both increase bllod volume and therefore blood pressure
38
What are Anabolic Steriods , how are they used psoitively and negatively and what are theyre side effects
- they can be used to treat hormone imablances and diseases that cause muscle loss like cancer and aids - body builders and atheletes abuse steriods to gain advantage - they can cause paranoia, aggression, delusions, impaired judgement and mania
39
What is Growth hormone, how are they used psoitively and negatively and what are theyre side effects
They can be used for children that are defecient in HGh and soemtimes some adults peoples exploit it when trying to gain muscles - used in agriculture to gain muscles mass can worsen cardiovascular disease, hypertension and abnormal growth of organs
40
What is recombiant DNA technolgoy and how is it used
Technology that can produce synthetic hormones EX: insulin - endocluase is used to isolate a specfic segment of humane genome that codes for a hormone - restriction enzyme is used to make an opening in the plasmid of the bacteria - ligase glues the human gene and bacteria - the bacteria will procreate and create the hormone and it can be harvested
41
How can MRIS and CTSCANs be used
To idenitdy tumours on endorcrine glands - tumours may affects the release of hormones
42
How can Urinalysis be used
24 hours urine collection to test for hormones
