Question

endocrine glands secrete hormones directly into * 2 points
synaptic gaps
the bloodstream
sensory neurons
dendrites

sophia came home late. as she reached to turn on the kitchen light, her * 2 points hand brushed against something unexpected. her adrenal glands, as part of the “flight - or - flight” response, released epinephrine and norepinephrine, which increased her heart rate and blood pressure. even after she realized it was just a curtain, her excited feelings lingered. this example illustrates
how chemicals can amplify or block a neurotransmitters activity
the all - or - none response in neural firing
that endocrine messages tend to outlast the effects of neural messages
how a myelin sheath insulates and increases the speed of the neural messages

Explanation:

1. Endocrine glands secrete hormones directly into the bloodstream to reach target cells throughout the body. Synaptic gaps are for neurotransmitter release in the nervous - system, sensory neurons are for transmitting sensory information, and dendrites receive signals from other neurons.
2. In the second example, Sophia's adrenal glands released hormones (epinephrine and norepinephrine) as part of the "fight - or - flight" response. Even after the initial threat was identified as non - existent (just a curtain), the effects of these hormones (excited feelings) lingered, showing that endocrine messages tend to outlast the effects of neural messages. Neural messages are fast but short - lived compared to the more long - lasting hormonal effects.

Answer:

1. the bloodstream
2. that endocrine messages tend to outlast the effects of neural messages
