Glucocorticoid secretion increases in response tostress. Which of the following
hormones will cause the adrenal gland to releaseglucocorticoids?
Growth hormone (GH)
adrenaline
Anti-diuretic hormone (ADH)
ACTH
During the Endocrine Ed simulation, what hormone secretionincreased when the
lights were turned out allowing Ed to sleep?
a.ACTH
b.adrenaline
c.thyroid stimulating hormone (TSH)
d.melanin
During labor, the baby's head pushes against the mother's cervixcausing nerve
impulses to transmitted to the brain to stimulate release ofoxytocin from the
pituitary gland into the blood stream. Increased levels of oxytocinin the blood
stream stimulate uterine contractions which results in the baby'shead pushing
against the mother's cervix. The process repeats causing more andmore
oxytocin to be released into the blood stream stimulating strongerand more
frequent contractions.
Is this an example of negative feedback?
a.Yes
b.No
Which of the following accurately describes the typicaltransmission of an
electrical signal through a neuron?

d.dendrite>cell body>axon
Which of the following is defined as a small gapbetween transmitting and
receiving neurons?
a.cell body
b.axon
c.synaptic terminal
d.synaptic cleft

When you performed the \"ruler catching\" experiment, which of thefollowing
accurately describes the muscles used to catch the ruler?
a.sensory receptors
b.integration centers in the brain
c.effector cells
When a response \"skips\" the integration process where the brainmakes a decision about

other words, if a response to a stimulus is made involuntarywithout conscious thought,
how would the relay system used by the nervous system bedescribed?
