Flashcards in Intro to Endocrine Physiology Deck (22):
1

How is the endocrine system different from nervous system

Uses hormones instead of neurotransmitters to signal distant sites in the body

2

How too signals travel in the endocrine system

Through the blood which helps it to circulate long distance

3

What is a hormone

A chemical signal secreted into the blood stream to a ct on a different tissue

4

How is a signal received in a long distant cell

The cell must have the hormone receptor (target cell) in order to have a response

5

Does the same hormone signal the same action in every cell

No, different cells with the same receptor will present different actions

6

What structure releases hormones

Glads and cells within an organ

7

List 5 glands/tissues that release hormones

Pituitary
Pancreas
Hypothalamus
Thyroid
Adrenal

8

How are hormones classified

Based on what they are made of (their precursors/building blocks)

9

What are the 3 main types of hormones

1.Peptide/Protein
2.Steroid
3.Amine

10

What are examples of peptide/protein hormones

Insulin
Hypothalmic hormones
Pituitary hormones

11

What is the precursor for peptide/protein hormones

Amino acids

12

What is the solubility of peptide/protein hormones

Hydrophilic

13

What is the transportation of peptide/protein hormones in blood like

They are able to circulate through the blood with no help

14

For peptide/protein hormones, where is the receptor on the target cell

Surface receptors outside of the plasma membrane

15

What are examples of steroid hormones

Testosterone
Estrogen
Cortisol

16

What is the precursor for steroid hormones

Cholesterol (Fat)
-ring structure

17

What is the solubility of steroid hormones

Hydrophobic
-fat loving

18

What is the transportation of steroid hormones in blood like

They need carrier proteins in order to move steroid hormones through the blood

19

For steroid hormones, where is the location of the receptor on the target cell

Receptors are inside the cell
-intracellular

20

Where are examples of amine hormones

Epinephrin
T3 T4

21

What is the precursor for amine hormones

Tyrosine (an amino acid)

22

What is the solubility of amine hormones

Can either be hydrophobic or hydrophilic
-Those that are hydrophobic like T3&4 have to have protein carriers added in order to be transported through the blood
