Glucocorticoid secretion increases in response to
stress. Which of the following
hormones will cause the adrenal gland to release
glucocorticoids?
Growth hormone (GH)
adrenaline
Anti-diuretic hormone (ADH)
ACTH
During the Endocrine Ed simulation, what hormone secretion
increased 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 cervix
causing nerve
impulses to transmitted to the brain to stimulate release of
oxytocin from the
pituitary gland into the blood stream. Increased levels of oxytocin
in the blood
stream stimulate uterine contractions which results in the baby's
head pushing
against the mother's cervix. The process repeats causing more and
more
oxytocin to be released into the blood stream stimulating stronger
and more
frequent contractions.
Is this an example of negative feedback?
a.Yes
b.No
Which of the following accurately describes the typical
transmission of an
electrical signal through a neuron?
a.cell body>dendrite>axon
b.axon>dendrite>cell body
c.axon>cell body>dendrite
d.dendrite>cell body>axon
Which of the following is defined as a small gap
between transmitting and
receiving neurons?
a.cell body
b.axon
c.synaptic terminal
d.synaptic cleft
Fill in the blanks with the correct word(s).
In the central nervous system (CNS), neurons bundled together are
called Blank 1.[ ]
. In the peripheral nervous system (PNS), neurons bundled together
are
called Blank 2 [.]
When you performed the "ruler catching" experiment, which of the
following
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 brain
makes a decision about
how to respond to a stimulus, how would we describe this action by
the nervous system? In
other words, if a response to a stimulus is made involuntary
without conscious thought,
how would the relay system used by the nervous system be
described?
a.neural integration
.b.motor neuron output
c.sensory input
c.spinal reflex arc
Glucocorticoid secretion increases in response to stress. Which
of the following
hormones will cause the adrenal gland to release
glucocorticoids?
Ans: ACTH Adrenocorticoropic hormone released from hypothalamus and initiate the adrenal gland to release metobolic hormones
During the Endocrine Ed simulation, what hormone secretion
increased when the
lights were turned out allowing Ed to sleep?
Answer: melanin: a hypothalamic peptide hormone maintains the behaviour, mood, sleep wake cycle

Is this an example of negative feedback?
b.No
This is positive feedback process. till the pressure receptors in birth canal feels the pressure of baby sends the positive signal and amplifies the release of hormon oxytocin
Which of the following accurately describes the typical
transmission of an
electrical signal through a neuron?
First neurone attaches dendrites as signal receptor, signal goes to cell body then axon then again to other dendrite so ans is Dendrite- cell body-axon
Which of the following is defined as a small gap between
transmitting and
receiving neurons?
Synaptic cleft: a gap between axon terminal and dendrite membranes and transmits signals using neurotransmitter and corresponding receptors
In the central nervous system (CNS), neurons bundled together
are called [Tracts]
. In the peripheral nervous system (PNS), neurons bundled together
are
called [nerve.]
