Answer
Neurotransmitters are chemical messengers that transmit signals across a chemical synapse, such as between neurons, while neurohormones are hormones that are produced by neurosecretory cells and released into the bloodstream.
Solution
a
Location of action: Neurotransmitters act at the synapse between two neurons, whereas neurohormones are released into the bloodstream and can affect distant target cells
b
Mode of release: Neurotransmitters are released from the presynaptic neuron in response to an action potential, while neurohormones are released from neurosecretory cells into the circulatory system
c
Types of target cells: Neurotransmitters typically target the postsynaptic neuron or muscle cells, whereas neurohormones can target a variety of cells throughout the body
Key Concept
Neurotransmitters and neurohormones are both involved in communication within the body but differ in their mechanisms of action and range of effect.
Explanation
Neurotransmitters are involved in rapid signaling between neurons at synapses, while neurohormones have a broader and often longer-lasting effect by traveling through the bloodstream to reach various organs and tissues.
