Question 2

Neurons are to the nervous system what ____ are to the endocrine system.

Accepted Answer

Hormones are to the endocrine system what neurons are to the nervous system. Both hormones and neurons are chemical messengers that transmit signals throughout the body.

Question 4

Jacelyn is wandering through a national park when she sees a bear lumbering toward her.As her fight-or-flight reaction is triggered,what hormones are being released in her body in response to the perceived threat?

Accepted Answer

ACTH (adrenocorticotropic hormone) and cortisol are released in response to stress and perceived threat, such as encountering a bear in the wild. These hormones help prepare the body for fight or flight by increasing heart rate, blood pressure, and glucose levels, while also suppressing non-essential functions such as digestion and immunity. Melatonin and progesterone are hormones involved in sleep and reproductive processes, and would not be released in this scenario. Estradiol and testosterone are sex hormones with various roles in the body, but not specifically related to stress response. Insulin and corticosteroids are involved in glucose metabolism and inflammation, respectively, but again, are not the primary hormones released in response to perceived threat.

Question 6

Scientists have just discovered a new hormone that appears to have very specific effects.This specificity of effects is most likely due to ____.

Accepted Answer

The specificity of the new hormone's effects is most likely due to its unique receptors on the target organs. Receptors are proteins on the surface of cells that bind specific hormones, and the specific shape of the receptor determines which hormones can bind and exert their effects on that cell.

Question 7

In the nervous system,neurotransmitters are the main means of communication between neurons.The main means of communication between organs in the endocrine system is by ____.

Accepted Answer

Hormones are the main means of communication between organs in the endocrine system. Hormones are produced by glands and secreted into the bloodstream, where they can travel to target cells in distant organs or tissues to elicit a response. Cytokines are signaling molecules that are important in the immune system, but they are not the main means of communication between organs in the endocrine system. The thalamus is a part of the brain that is involved in relaying sensory information, but it is not directly involved in communication between organs in the endocrine system.

Question 8

While babysitting one night,you receive a phone call from someone who says,in a really weird voice,"I am coming to get you! I am coming to get you!" Just then,the lights in the house flicker out! As you are alone,your heart starts beating faster,you begin to perspire,and you are covered in goose bumps.You have just experienced the ____.

Accepted Answer

The symptoms described are characteristic of the fight-or-flight syndrome, which is the body's acute stress response to a perceived threat, preparing you to either fight or flee.
