Example Questions
Example Question #163 : Biology
What is considered the primary advantage of endocrine communication (using hormones) throughout the body as compared to neural communication (using neurotransmitters)?
Neurotransmitters often fail to reach their intended targets, while hormones inevitably arrive where they are intended.
The changes to the body created by neurotransmitters are harder to reverse after danger passes than the ones created by hormones.
There is a limited supply of neurotransmitters, while the supply of hormones is virtually unlimited.
The changes to the body induced by hormones last for much longer than those induced by neurotransmitters.
The changes to the body induced by hormones last for much longer than those induced by neurotransmitters.
Hormones, or chemicals released by the endocrine system into the bloodstream for delivery throughout the body, have a much longer lifespan than neurotransmitters, and induce changes to body systems that last for hours, days, or which can even be permanent.
Example Question #1461 : Ap Psychology
Which gland in the body is responsible for influencing levels of excitability via influencing the levels of calcium and phosphates in the bloodstream?
Pineal gland
Thyroid gland
Pituitary gland
Parathyroid gland
Parathyroid gland
The parathyroid gland can also release large doses of parathyroid hormone into the body in response to low blood calcium, a process which may influence the development of osteoporosis.
Example Question #292 : Biology And Sensation
Which of the following is NOT typically symptomatic of an excess of thyroxine (hyperthyroidism)?
Weight gain
Insomnia
Fatigue
Excitability
Weight gain
Hyperthyroidism also causes a reduced attention span and can lead to long-term neurological problems, and is typically treated with medication and (when necessary) surgical intervention. Hyperthyrodism can often result in a loss of necessary body weight, as opposed to weight gain. Hypothyrodism can result in weight gain.
Example Question #1461 : Ap Psychology
One example of a hormone which operates on a positive feedback loop is _____________.
Thyroxine
Oxytocin
ACTH
Testosterone
Oxytocin
Oxytocin works on a positive feedback loop because the actions which oxytocin causes also cause more oxytocin to be produced. This can be seen, among other examples, in the contractions of labor.
Example Question #293 : Biology And Sensation
Neurotransmitters and hormones both send chemical messages. Which of the following best explains the difference between neurotransmitters and hormones?
Hormones are part of the endocrine system and not the nervous system
Hormones are slower than neurotransmitters
Hormones are transmitted through the bloodstream and not between neurons
All of these
All of these
Neurotransmitters and hormones are both types of chemical messages. Because hormones are transmitted through the circulatory system, they take much longer for the messages to be received compared to the nervous system, which sends signals extremely quickly. Different glands secrete hormones in the endocrine system like the pituitary gland and adrenal gland.
Example Question #171 : Biology
Which of the following hormones is associated with bonding, empathy, and trust?
Endorphins
Oxytocin
Dopamine
Testosterone
Oxytocin
Oxytocin is a hormone found in mammals that is associated with bonding, empathy, and trust. Testosterone is also a hormone, but it is associated with sexual development in males. Dopamine and endorphins are both associated with positive feelings, but they are types of neurotransmitters—a different type of chemical messengers—not hormones.
Example Question #295 : Biology And Sensation
A decrease in blood glucose level can be best combatted by doing which of the following?
Eating a snack
Sleeping
Drinking Water
Excercising
Eating a snack
"Eating a snack," specifically one filled with carbohydrates would introduce sugar into the body. After being absorbed into the bloodstream, the levels of glucose in the blood would rise to normal blood glucose levels. All other answer choices do not include a resolution to rectify low blood sugar levels.
