Fenestrated?
What is it and where is it found? |
Capillaries are fenestrated this means that they will have little holes because many of the molecules that need to pass through the capillary are large.

|
What are the fat soluble Hormones?
|
-Estrogen
-Progesterone -Testosterone -Cortisol -Aldosterone -Thyroxin --> odd ball |
|
|
Fat VS. Water
Fat Soluble hormones |
-Bound hormone
-Effective longer -Carrier molecule -gene activation -hydrophobic |
|
|
Fat VS. Water
Water Soluble Hormones |
-un-bound hormone
-NO carrier protein -Less effective -cAMP activation -Hydrophilic |
|
|
what are the 3 types of control mechanisms for hormones?
|
-Nervous
-Humeral -Hypothalmic/pituitary axis mechanism |
|
|
Nervous control of hormones
|
Every endocrine gland is controlled by your nervous system and all are supplied with neurons (sympathic and parasympathic)
|
|
|
Humeral control of hormones
|
Unique control relationship where 2 hormones will work together one hormone will raise other hormone will lower
- if a raise in a hormone affects a totally different hormone this is also a humeral relationship |
|
|
Hypothalmic/pituitary axis mechanism control of hormones
|
-How most of our hormones are controlled
-Relationship between the hypothalamus and the pituitary |
|
|
Pituitary anatomy
|
- it is held i a boney confine of the skull (protection)
-The infundibulum of the pituitary is twisted in life |
|
|
Anterior pituitary
|
- Adenohypothosis
-Endocrine part - Epithelial tissue that is glandular in nature |
|
|
Posterior pituitary
|
- Nerohypothosis
-Nervous system part -Nervous tissue will come from the brain tissue |
|

Super Optic
|
in the posterior pituitary
it is important in regulating how much water you have in your body Will make ADH Neurosceratory cell |
|
|
ADH
|
target cell is the kidney
will bind to the receptor to make aqua pores |
|
|
Aqua Pores
|
allow some of the water that would have been take out as urine to go back into your body and into your blood stream
|
|
|
Neurosceratory cells
|
-look like motor neurons
-have a long axon like structure -NOT a blood vessel |
|
|
Perinventricular cells
|
-Make and store oxytocin
|
|
|
Prolactin
|
-Made in anterior pit
-Plays a role in producing milk |
