Final answer:
A synapse between an axon ending and another neuron's cell body is called an axosomatic synapse, which is true. Neurons typically have a single axon which branches out to form multiple terminals each capable of forming synapses.
Step-by-step explanation:
The statement that a synapse formed between the axon ending of one neuron and the cell body of another neuron is called an axosomatic synapse is True. In the nervous system, synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. When the action potential reaches the axon terminal, it triggers the release of neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic cell, potentially causing an action potential in that cell. The term 'axosomatic' specifically refers to the synapse between an axon and a soma, or cell body, of another neuron.
Addressing another point, neurons typically have one axon; however, this single axon may branch out multiple times, leading to the formation of numerous axon terminals. Each of these terminals can form a synapse with different target cells, such as the dendrites, soma, or axon of other neurons, or the effector cells in muscles or glands. Therefore, though there is only one axon per neuron, that axon can have multiple terminals creating various synapses.
