Question

Which of the following stimuli can commonly activate or inhibit neurons?

A) Mechanical pressure

B) Changes in temperature

C) Chemical neurotransmitters

D) Changes in atmospheric pressure

Answer 1

Mechanical pressure, chemical neurotransmitters, and changes in temperature can commonly activate or inhibit neurons.

Step-by-step explanation:

Neurons can be activated or inhibited by various stimuli. The following stimuli commonly activate or inhibit neurons:

1. Mechanical pressure: Neurons can respond to physical pressure, such as touch or vibration. For example, when you touch something hot, your skin's sensory neurons are activated and send signals to your brain.
2. Chemical neurotransmitters: These chemicals are released by neurons and can either excite or inhibit other neurons. For example, the neurotransmitter dopamine can excite certain neurons involved in neurological processes.
3. Changes in temperature: Neurons can also respond to changes in temperature. For instance, thermoreceptor neurons in your skin can be activated by hot or cold temperatures, sending signals to your brain.
