nervous and endocrine system
the part of the human central nervous system that controls breathing is the
medulla
the mechanism that regulates the secretion of hormones by the endocrine glands is called
negative feedback
organ that releases homeostasis
pancreas
the hormones insulin and glucagon are produced by the
pancreas
which structure contains specialized cells that are secrete the hormones insulin and glucagon
pancreas
a very high level of calcium in the blood suggests function of the
parathyroid
which structures secrete hormones that influence proper bone structure and development
pituitary and parathyroid
which process would most likely be affected if the part of the cerebrum was damaged
reasoning and speech
which is the first structure stimulated in a reflex arc
receptor
in multicellular organisms, cells must be able to communicate with each other. structures that enable most cells to communicate with each other are known as
receptor molecules
which is a correct route of an impulse in a reflex arc
receptor-sensory neuron-interneuron-motor neuron-effector
what does the spinal cord control
reflex actions
which is NOT an endocrine gland
salivary gland
in order to stimulate an effector in a toe, which pathway does a nerve impulse follow after it is initiated at a receptor
sensory neuron--interneuron-- motor neuron (S.I.M)
effectors are the best described as
structures that respond to stimuli
which statement describes a feedback mechanism involving the human pancreas
the level of sugar in the blood is affected by the amount of insulin in the blood
a person's rate of metabolism is regulated by a hormone secreted by the
thyroid
which gland could become enlarged due to a lack of iodine in the diet (goiter)
thyroid
which gland produces parathormone, which regulates the metabolism of calcium
thyroid
a neurotransmitter is best described as
a chemical that helps to relay impulses
what will most likely result if a diabetic injects an overdose of insulin
a dangerous drop in blood sugar levels
a substance directly involved in cellular communication within the human body is
a hormone
a change in the external or internal environment of an organism is known as
a stimulus
which structure secretes the substance it produces directly into the bloodstream
adrenal gland
what do adrenal glands produce
adrenaline
in a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through
an interneuron
which portion of the central nervous system coordinates motor activities and aids in maintaining balance
cerebellum
loss of memory as a result of an accident would indicate damage to the
cerebrum
diabetes is a disease associated with extremely low levels of insulin, a hormone which controls sugar levels in the blood. people with diabetes would be considered to have malfunctions in which human system
endocrine
which hormone stimulates activity in the ovaries
follicle stimulation
the body normally responds to low concentrations of sugar in the blood by secreting
glucagon
insulin is a molecule, produced by the endocrine system, which regulates sugar concentration in the blood. most likely, insulin is a
hormone
neurons are to neurotransmitters as endocrine glands are to
hormones
the part of the brain that is most directly related to the endocrine system
hypothalamus
hormone responsible for homeostasis
insulin
which hormone aids directly in reducing the sugar level of the blood
insulin
