You've sort of got it backwards: axon terminals initially release neurotransmitters into the synaptic cleft, from where they diffuse across the cleft and fit into receptor sites on ligand-gated sodium ion pores on the dendrites, causing those pores to open, allowing sodium ions into the dendrite, resulting in a change in the voltage of the dendrites membrane, which initiates the propagation of the signal along the dendrite and soma towards the axon hillock, where it may trigger an action potential in the axon.
However, after the neurotransmitters have done their job at the dendrites, they can be "released" by the dendrites , as in let go of, to be re-absorbed, re-cycled, re-used by the axon terminals.
The axons "give" the neurotransmitters to the dendrites as chemical messengers to convey the signal, and the dendrites "give them back" after the message has been received and conveyed onward.
An axon sends signal from dendrites to terminals to release neurotransmitters
The post-synaptic part of a neuron in humans is typically referring to the dendrites and cell body (soma). These structures receive signals from other neurons via neurotransmitters released at synapses.
Receptor sites on the membrane of a neuron's dendrites receive neurotransmitters, which are chemical messengers released by neighboring neurons. When these neurotransmitters bind to their specific receptors, they can initiate changes in the neuron's electrical state, leading to either excitatory or inhibitory signals. This process is essential for synaptic transmission and plays a crucial role in neural communication and processing information.

Dendrites are the extensions of a neuron that receive signals from other neurons. They are responsible for transmitting electrical impulses towards the cell body of the neuron.
Not really, but sort of, eventually. Initially they receive neurotransmitters which are originally released by axon terminals into the synaptic cleft; then, after they have done their job of opening ligand-gated ion pores to allow sodium ions into the dendrite, which initiates a graded potential in the dendrite, they are then released so they can be re-absorbed and re-used by the axon terminals as new impulses reach the axon terminals.But functionally it is the axon which releases neurotransmitters, when an action potential causes it, so that dendrites can receive them. The dendrites only "release" them after their job is done, so they can be re-used.
Dendrites are the beginning of action potentials as they are formed and then propagate through a neuron. At the synapse, the dendrites receive the incoming signal from neurotransmitters released at the terminal of the previous neuron.

Receive, fundamentally, but then subsequently release when its job is done. The axon releases neurotransmitters into the synaptic cleft, where they diffuse across and fit into the receptor sites on ligand-gated ion pores located on the dendrites, where they act to open the ion pores so as to initiate the propagation of the neural signal along the dendrite ; however, those same receptor sites subsequently do release the neurotransmitters, so they can be re-absorbed and re-used by the axon terminals to pass neural signals to the dendrite as subsequent action potentials reach the ends of the axons.
Dendrites are the part of a neuron which receives chemical messages (neurotransmitters) through synapses.Mostly the dendrites receive messages from other neurons, but the cell bodies of neurons also receive direct synaptic inputs from other cells.
The post-synaptic part of a neuron in humans is typically referring to the dendrites and cell body (soma). These structures receive signals from other neurons via neurotransmitters released at synapses.
No, a dendrite is not bordered by a synapse. A synapse is a junction between two neurons where communication occurs by the release of neurotransmitters. Dendrites are the branching structures of a neuron that receive signals from other neurons through these synapses.
Dendrites are the branched projections of a neuron that receive signals from other neurons. They contain receptors that detect neurotransmitters released by neighboring neurons. The main function of dendrites is to integrate and transmit these signals to the cell body of the neuron.
In general, but not always, dendrites receive neurochemical information from neurotransmitters released by axons. Dendrites are branched extensions of the neuronal cell body, or soma, that receive information from other neurons. The dendrite is the post-synaptic portion of many synapses within the nervous system that contains synaptic receptors that bind to neurotransmitters and respond by excitation or inhibition of the membrane potential.
Receptor sites on the membrane of a neuron's dendrites receive neurotransmitters, which are chemical messengers released by neighboring neurons. When these neurotransmitters bind to their specific receptors, they can initiate changes in the neuron's electrical state, leading to either excitatory or inhibitory signals. This process is essential for synaptic transmission and plays a crucial role in neural communication and processing information.
The dendrites of the neuron receive most of the incoming signals from other neurons. These dendrites act as the primary site for receiving neurotransmitters released by neighboring neurons.
