Endocrine

1.       The endocrine system works closely with the nervous system to: regulate metabolic activities throughout the body and maintain homeostasis.

2.       While the nervous system communicates rapidly through electrical impulses, the endocrine system communicates through: hormones that travel through the bloodstream to target tissues.

3.       Together the endocrine and nervous systems: regulate metabolism, growth and development, energy production, reproduction, stress response, fluid balance, and temperature regulation.

4.       _______are natural chemical messengers produced by specific glands or cells: hormones

5.       Once released into the bloodstream, hormones travel to: target tissues.

6.       Target tissues are tissues that have: receptors that correspond to a specific hormone.

7.        When the hormone binds to the receptor on the target tissue: the tissue responds by changing its activity.

8.       The endocrine system maintains balance in the body through a regulatory mechanism called: negative feedback.

9.       Negative feedback occurs when a hormone is released in response to a: change in the body

10.  During negative feedback, that hormone that is released in response to the change in the body, produces an effect that: counteracts the original change in order to restore homeostasis.

11.  Homeostasis refers to: the constant internal balance that the body attempts to maintain.

12.  Major endocrine glands include: the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and reproductive glands.

13.  The adrenal glands are small glands located: on top of each kidney

14.  adrenal glands are responsible for: producing hormones involved in stress response and metabolic regulation.

15.  The terms hyper and hypo are commonly used when discussing:endocrine disorders.

16.  Hyper refers to: excessive hormone activity or increased function of a gland

hypo refers to: reduced hormone activity or decreased gland function.
