Hormones and Sex - Neuroendocrine System - Regulation of Hormone Levels
6 important questions on Hormones and Sex - Neuroendocrine System - Regulation of Hormone Levels
Hormone release is regulated by three different kinds of signals. Which different kind of signals?
1. Regulation by Neural Signals
2. Regulation by Hormonal Signals
3. Regulation by Nonhormonal Chemicals
Which endocrine gland is the only one not regulated by neural signals?
The anterior pituitary.
By what sort of neurons are endocrine glands in the brain (hypothalamus and posterior pituitary) regulated?
Cerebral neurons.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
By what sort of neurons are those outside the CNS located regulated?
The autonomic nervous system; usually by both the parasympathetic and sympathetic nervous system.
Which two explanations could be merely different aspects of the same hypothetical mechanism?
1. Experiential explanation.
2. Hormonal explanation.
How are hormone levels regulated by hormonal signals?
When tropic hormones influence other hormones, these other hormones will provide feedback to the higher endocrine gland (pituitary or hypothalamus) which will respond to the feedback by sending less/more hormonal signals.
