Neural stimuli

Definition

Neural stimuli are signals from the nervous system that trigger hormone release from endocrine glands. These stimuli often involve neurotransmitters that directly influence hormone secretion.

5 Must Know Facts For Your Next Test

1. Neural stimuli often involve the hypothalamus and sympathetic nervous system.
2. The adrenal medulla is a key gland activated by neural stimuli to release adrenaline.
3. Neurotransmitters such as norepinephrine can act as neural stimuli.
4. Neural stimuli allow for rapid response to stress through hormone release.
5. Hormones released due to neural stimuli can affect various body systems, including cardiovascular and metabolic functions.
