How do neurotransmitters differ from hormones in terms of their functions and modes of action within the body?

Neurotransmitters are chemical messengers that transmit signals between nerve cells, while hormones are chemical messengers that regulate various bodily functions. Neurotransmitters act locally at synapses, while hormones travel through the bloodstream to target cells.


How do hormones differ from neurotransmitters in terms of their mode of action and physiological effects?

Hormones are chemical messengers that travel through the bloodstream to target cells, affecting a wide range of physiological processes over a longer period of time. Neurotransmitters, on the other hand, are released by neurons to quickly transmit signals across synapses in the nervous system, leading to more immediate and localized effects.


What are the differences between photo receptors and signal receptors?

Photoreceptors are specialized sensory cells that detect light and convert it into electrical signals, primarily found in the retina of the eye. In contrast, signal receptors are a broader category that includes various types of receptors that detect chemical signals, such as hormones or neurotransmitters, and initiate a cellular response. While both types of receptors are essential for communication within organisms, photoreceptors are specifically tuned for light detection, whereas signal receptors can respond to a wide range of stimuli. Their mechanisms of action and the types of signals they respond to differ significantly.


How do the functions of the endocrine system differ from those of the nervous system?

The endocrine system uses hormones to regulate bodily functions over a longer period of time, while the nervous system uses electrical signals to control rapid responses.


Which hormone is most similar to oxytocin in chemical structure?

Vasopressin is the hormone most similar to oxytocin in chemical structure. Both hormones are nonapeptides, containing nine amino acids, and differ by only two amino acids in their structure.


What symptoms can chemical exposure cause?

Symptoms differ from a chemical to other.


How does the endocrine system differ from the nervous system in terms of communication and regulation within the body?

The endocrine system uses hormones to communicate and regulate bodily functions slowly over time, while the nervous system uses electrical signals to communicate quickly for immediate responses.
