and Answers
Hormones from the adrenal medulla increase
blood pressure
heart rate
breathing rate
Secretions that affect only nearby cells are termed
paracrine
Steroid hormones
are soluble in lipids
combine with protein receptor molecules
cause messenger RNA synthesis
The hormone that stimulates calcium deposition into bone is
calcitonin
The pineal gland is
attached to the thalamus.
Which of the following hormones primarily affects the reproductive organs?
Follicle-stimulating hormone
What happens to GH and ADH with age?
levels of GH decrease but levels of ADH increase
The secretion of parathyroid hormone is controlled primarily by the
concentration of blood calcium
Pheromones differ from hormones in that
they are transmitted between members of the same species
Which of the following has both endocrine and exocrine functions?
pancreas
The specificity of hormone action derives from
target cell receptors that are unique for each hormone
A person under stress may have a lowered resistance to infection.
True
Steroid hormones diffuse through cell membranes, then bind with receptors, whereas nonsteroid
hormones bind receptors on the target cell membrane.
