20 Questions
How does the nervous system primarily function?
Using neurotransmitters to influence body tissues
What is the main function of the pituitary gland in the endocrine system?
To 'tell' other glands in the body what to do via neural and hormonal pathways
How do tissue and organ responses to endocrine hormones compare to those induced by neurotransmitters?
They are slower but more prolonged
What is the role of the hypothalamus in the endocrine system?
To tell the pituitary gland to start or stop making hormones
Which component of the endocrine system binds specifically with other molecules to trigger specific physiological changes in a target cell?
Receptors
What is the integrative center of the endocrine system?
Hypothalamus
Which gland is actually an extension of the hypothalamus?
Posterior pituitary
How does the hypothalamus exert hormonal control at the anterior pituitary gland?
By producing effector hormones
What regulates the endocrine system by inhibiting hormone overproduction?
Negative feedback system
What may result from defects in endocrine function?
Inflammation of glands
What are the 3 major components of the endocrine system?
Glands, hormones, and receptors
Which gland acts as the integrative center of the endocrine system?
Hypothalamus
What type of feedback occurs through an axis established among the hypothalamus, pituitary gland, and target organ?
Negative feedback
What may result from defects in endocrine function?
Hypersecretion or hyposecretion of hormones
In response to stimulation, what type of molecules bind specifically with receptors to trigger specific physiological changes in a target cell?
Hormones
What is the main function of the posterior pituitary gland in the endocrine system?
To produce and store effector hormones from the hypothalamus
What is the main difference in the means of control between the endocrine and nervous systems?
The endocrine system uses hormones, while the nervous system uses neurotransmitters
Which gland acts as the 'master gland' of the endocrine system?
Pituitary gland
How do tissue and organ responses to endocrine hormones compare to those induced by neurotransmitters?
Endocrine hormone responses are slower and longer than neurotransmitter responses
What connects the endocrine system with the nervous system and instructs the pituitary gland to start or stop making hormones?
Hypothalamus
Explore the differences between the endocrine and nervous systems in regulating body functions, including the means of control, speed of control, and the impact on body tissues. Understand the use of neurotransmitters in the nervous system and hormones in the endocrine system.
