Question: For a signal to travel from a neuron across a synapse and stimulate a response, the postsynaptic target cell must: be able to receive signals through the bloodstream. have receptor proteins for the signal released by the neuron. be a neuron. have an intracellular neural network to connect to the body's nervous system.

Nerve signals travel in the following manner: A dendrite of a sensory neuron receives the signal; its cell body transmits the signal to a motor neuron's axon, and the signal is sent to the target. b. An axon of a motor neuron receives the signal; its cell body transmits the signal to a sensory neuron's dendrite, and the signal is sent to the target. c. Efferent neurons conduct nerve impulses toward the cell body of sensory neurons, which send them on to interneurons and, ultimately, to afferent motor neurons. d. A dendrite of a sensory neuron receives the signal; the cell's axon transmits the signal to an interneuron, and the signal is transmitted by efferent neurons to effectors. The axons of oligodendrocytes transmit nerve impulses to the dendrites of astrocytes.
Adi S.
The junction between two communicating neurons is called a _____________; there is a _________ _________ between them across which the impulse must be conveyed. Synaptic transmission it the process by which the impulse in the presynaptic neuron is transmitted across the synaptic cleft to the postsynaptic neuron. When an impulse reaches the synaptic knob of an axon, synaptic __________ release chemicals called __________ into the synaptic _________. These chemicals react with specific receptors on the postsynaptic membrane.
Sri K.
Transmission of the nerve impulse across a synapse is accomplished by a. the release of $\mathrm{Na}^{+}$ at the presynaptic membrane. b. the release of neurotransmitters at the postsynaptic membrane. c. the reception of neurotransmitters at the postsynaptic membrane. d. Both a and c are correct.
