Describe the basic functions of transitional tissue. – Answer ☑️STRETCHING
,Differentiate between neural and endocrine signal strength conveyance –
Answer ☑️Endocrine: Concentration of hormone
Neural: Frequency of impulse
What are the three ways hormone release is controlled? – Answer ☑️- Humoral
- Hormonal

Describe up regulation – Answer ☑️Upon binding to a hormone, a cell will produce more
receptors for that hormone
Describe down regulation – Answer ☑️Upon binding to a hormone, a cell will destroy
existing receptors for that hormone

What two organs are largely responsible for removing hormones from the system? –
Answer ☑️Kidneys: Filter hormones out
Liver: Breaks hormones down
Briefly describe synergistic hormones. – Answer ☑️Hormone A + Hormone B = Larger
effect than the simple summation of the two hormones (almost like they are multiplied by
one another)
Briefly describe permissive hormones. – Answer ☑️Hormone A requires the presence of
