Which best describes the transmission of messages at the synapse?
a.
Hormones are released by pre- and post-synaptic neurons, transmitting messages across the synapse.
b.
Presynaptic neurons release neurotransmitters which travel across the synaptic cleft, binding to post-synaptic receptor sites.
c.
Postsynaptic neurons release neurotransmitters which travel across the synaptic cleft, binding to pre-synaptic receptor sites.
d.
Small nerve filaments bridge the synaptic cleft, transmitting the nerve impulse between primary neurons.
