Explanation
Nerve transmission is primarily a chemical process. The correct answer is B.
Nerve transmission, also known as synaptic transmission, involves the release of neurotransmitters from the axon terminal of a presynaptic neuron, which then bind to specific receptors on the dendrites or cell body of a postsynaptic neuron. This chemical interaction causes an electrical signal, called an action potential, to be generated in the postsynaptic neuron, which then travels down the axon of the neuron and continues the transmission of the nerve impulse.
While there are mechanical and physical aspects involved in nerve transmission, such as the movement of ions across the neuronal membrane and the generation of an electrical charge, the primary mechanism of nerve transmission is through the release and binding of neurotransmitters, which is a chemical process. Additionally, nerve transmission is a biological process because it involves the interaction between living cells, specifically neurons and their supporting cells, and is mediated by the biological structures and processes within these cells.
