You're about to delve into the foundational elements of neurobiology, starting with the neuron's structure and functions. We'll then examine the means by which neurons communicate through synapses and neurotransmitters, concluding with an overview of the nervous system's organisation. Each aspect is vital for comprehending the operations of the brain and nervous system, so let's begin.

Embarking on this journey, we first look at the neuron, the basic unit of the nervous system. Neurons are specialised cells designed to transmit information throughout the body. Understanding the neuron involves recognising its parts, such as the soma, axon, dendrites, and the synaptic terminals, and grasping their functions is paramount.

Next, our attention turns to the synapses, the junctions where neurons communicate with each other. This process involves the release of neurotransmitters, chemicals that cross the synaptic gap to transmit signals between neurons. Grasping the mechanisms of synaptic transmission is key to understanding how thoughts, emotions, and behaviours are generated.

Finally, we review the organisation of the nervous system, which includes the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS encompasses the neural connections outside the CNS. Recognising the structure and function of these systems is essential for a comprehensive understanding of neurobiology.
