Question 1

Decerebration

Answer 1

A surgical procedure that
severs the brain stem, disconnecting the
hindbrain from the forebrain.

Question 2

Melanin-concentrating hormone

Answer 2

One of two peptide neurotransmitters
found in a system of lateral hypothalamic
neurons that stimulate appetite and reduce
metabolic rate.

Question 3

Orexin

Answer 3

One of two peptide
neurotransmitters found in a system
of lateral hypothalamic neurons that
stimulate appetite and reduce metabolic
rate. Also called hypocretin.

Question 4

Neuropeptide Y (NPY)

Answer 4

A peptide
neurotransmitter found in a system
of neurons of the arcuate nucleus that
stimulates feeding and insulin and
glucocorticoid secretion; decreases the
breakdown of triglycerides; and decreases
body temperature.

Question 5

Agouti-related protein (AgRP)

Answer 5

A neuropeptide that acts as an antagonist at
MC4Rs and increases eating

Question 6

Arcuate nucleus

Answer 6

A nucleus in the
base of the hypothalamus that controls
secretions of the anterior pituitary gland;
contains NPY-secreting neurons involved
in feeding and control of metabolism.

Question 7

Paraventricular nucleus (PVN)

Answer 7

A nucleus of the hypothalamus located
adjacent to the dorsal third ventricle;
contains neurons involved in the control
of the autonomic nervous system and the
posterior pituitary gland

Question 8

CART

Answer 8

Cocaine- and amphetamine regulated transcript; a peptide neurotransmitter found in a system of neurons of the arcuate nucleus that inhibit feeding

Question 9

a-melanocyte-stimulating hormone (a-MSH)

Answer 9

A neuropeptide that acts as an
agonist at MC4Rs and inhibits eating
