Final answer:
Nerve impulses are conducted via both electrical and chemical means. Electrical conduction happens through changes in electrical potential along a neuron, while chemical conduction involves neurotransmitters crossing a synapse.
Step-by-step explanation:
Means by which nerve impulses are conducted include both electrical and chemical mechanisms. Electrical conduction occurs when an impulse travels along the neuron's membrane due to a change in electrical potential. On the other hand, chemical conduction occurs at the synapse, where neurotransmitters are released from one neuron and bind to receptors on another neuron, transmitting the signal across the synaptic gap.
As part of the sensory transduction process, stimuli from the environment are converted into electrical signals by sensory organs, which are then transmitted via the nervous system. These signals can be propagated either through electrical synapses, which allow direct, rapid transmission, or through chemical synapses, which involve the release of neurotransmitters and are slightly slower but more versatile.
