What is the substance released into the synaptic cleft?
Neurotransmitters are the substances released into the synaptic cleft. They are chemical messengers that transmit signals across the synapse from one neuron to another.
Can you describe the difference between a neurotransmitter and a hormone?
Neurotransmitters are chemical messengers that transmit signals between neurons in the nervous system, while hormones are chemical messengers that regulate various bodily functions and are released into the bloodstream by glands.
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.
What is the difference between a hormone and a neurotransmitter in terms of their functions in the body?
Hormones are chemical messengers that travel through the bloodstream to regulate various bodily functions over longer periods of time, while neurotransmitters are chemical messengers that transmit signals between nerve cells in the brain and nervous system for more immediate and localized effects.
How is a hormone different from a neurotransmitter in terms of their mode of action in the body?
Hormones are chemical messengers released into the bloodstream to affect distant target cells, while neurotransmitters are released at synapses to transmit signals between nerve cells. Hormones act more slowly and have longer-lasting effects, while neurotransmitters act quickly and have more localized effects in the nervous system.

Why are hormones called chemical messengers?
I believe they are called chemical messengers because of their function and the fact it is a chemical. They travel through the blood and target cells respond to hormones often because of their structure. I have read in a science book (McDougal Littell 's Human Biology) that they are called chemical messengers because they are made at one location and function at another.
What type of chemical messeger will act locally on nearby cells?
Local chemical messengers that act on nearby cells are known as paracrine signals. These molecules are released by cells and affect neighboring cells within a short distance, facilitating communication and coordination of responses in tissues. Examples of paracrine signals include growth factors and cytokines. Unlike hormones, which travel through the bloodstream to target distant cells, paracrine signals exert their effects locally.
Are neurons chemical messages sent to the brain?
Neurons themselves are not chemical messages; rather, they are specialized cells that transmit electrical impulses. When a neuron communicates with another neuron, it releases neurotransmitters, which are chemical messengers that cross the synapse to relay information. These neurotransmitters can influence the activity of the receiving neuron, ultimately affecting how signals are processed in the brain. Therefore, while neurons send signals, the chemical messages are the neurotransmitters they release.
Intracellular chemical signals known as second messengers?
Second messengers are small molecules that transmit signals inside cells, amplifying and regulating the cellular response to the original stimulus. Common examples include cAMP, calcium ions, and IP3. They are crucial in cellular communication and are involved in a wide range of signaling pathways.
Hormones and secretions of the nervous system are chemical messengers that?
Both hormones and secretions of the nervous system are chemical messengers that help regulate various bodily functions. Hormones are produced by glands and released into the bloodstream to target distant organs, while nervous system secretions like neurotransmitters act locally at synapses to transmit signals between neurons. Both systems work together to maintain homeostasis and coordinate responses to internal and external stimuli.

What sends chemical messengers though the body?
The endocrine system is responsible for sending chemical messengers, known as hormones, throughout the body. Hormones are produced by various glands, such as the pituitary, thyroid, and adrenal glands, and they travel through the bloodstream to target organs and tissues. These messengers regulate numerous physiological processes, including metabolism, growth, and mood. Additionally, the nervous system can also send chemical signals through neurotransmitters to communicate between neurons and other cells.

How are neurotransmitters different from the impulses that travel along the bodies of nerve cells?
no you give an answer im the one that asked the question
