After a review of the lesson, complete the following multiple-choice items.

1. All the following statements about hormones are correct except
   
   
   1. hormones are produced by endocrine glands
   2. hormones travel to target cells in the body
   3. hormones are carried by the circulatory system
   4. hormones are used to communicate between different organisms
      
      
2. The hypothalamus controls the anterior pituitary by means of
   
   
   1. tropic hormones carried by nerve cells
   2. nervous stimulation by the sympathetic nervous system
   3. releasing hormones in the bloodstream
   4. both nervous and hormonal stimulation
      
      
3. All the following statements about the hypothalamus are correct except
   
   
   1. the hypothalamus functions as an endocrine gland
   2. the hypothalamus is part of the central nervous system
   3. the hypothalamus is subject to negative feedback.
   4. the neurosecretory cells of the the hypothalamus terminate in the anterior pituitary
      
      
4. Which of the following glands is controlled directly by the hypothalamus or central nervous system and not the anterior pituitary?
   
   
   1. Pancreas
   2. Adrenal medulla
   3. Adrenal cortex
   4. Posterior pituitary
      
      
5. In humans, the nervous and endocrine systems are similar in that both
   
   
   1. secrete chemical messages
   2. operate at the voluntary and involuntary level
   3. use highly specialized pathways
   4. respond very rapidly to stimuli
      
      
6. The main difference between the endocrine and nervous system is that only the endocrine system
   
   
   1. secretes chemical messengers
   2. is regulated by negative feedback
   3. depends on specialized neurosecretory cells
   4. relies completely on the circulatory system for transport
      
      
7. Compared with the response to a nerve impulse, the response to a hormone is usually
   
   
   1. shorter in duration and more widespread in effect
   2. shorter in duration and less widespread in effect
   3. longer in duration and more widespread in effect
   4. longer in duration and less widespread in effect
