The release of hormones by Metabolic activities of many tissues and organs
endocrine cells alters the simultaneously
1. Very specific responses to
environmental stimuli
2. Anatomical boundary between the
nervous and endocrine systems
3. Metabolic activities of many tissues
and organs simultaneously
4. Rate at which chemical
neurotransmitters are released
What is the main difference between Endocrine glands discharge their secretions directly
endocrine and exocrine glands? into the bloodstream
1. Endocrine glands discharge their
secretions directly into the
bloodstream
2. Endocrine glands discharge their
secretions through ducts
3. Exocrine glands are controlled
primarily by nerves
4. Exocrine glands secrete hormones
directly into the bloodstream
, Which of the following statements is They require a receptor in the plasma membrane and
true of amino acid-based hormones? employ intracellular second messengers
1. They cross the plasma membrane
and alter the expression of a gene
2. They require a receptor in the
plasma membrane and employ
intracellular second messengers
3. They are synthesized from
cholesterol and enter the cell directly
4. They are lipid soluble so therefore
cannot cross the membrane and
instead employ second messengers
Which one of these hormones is the Testosterone
only hormone that can act on
receptors inside the target cell and
directly activate specific genes?
1. Calcitonin
2. Growth hormone
3. Testosterone
4. Thyroid stimulating hormone
In the second-messenger cascade Binding to specific receptors and employing the
mechanism of hormone action, the services of G proteins and cAMP
hormone functions by
1. Entering the nucleus of a cell and
initiating or altering the expression of
a gene
2. Synthesizing more than one
hormone at a time
3. Binding to specific receptors and
employing the services of G proteins
and cAMP
4. Increasing the basal metabolic rate
in the target organ
