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
