The neuron and nervous system Show Introduction to neurons and glia. How the structure of a neuron allows it to receive and transmit information. The neuron and nervous systemBiology is brought to you with support from the Amgen Foundation What relays signals from the neuron to other cells?Neurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered.
Which part of the neuron sends signals?Neurons receive signals in a short antennae-like part called the dendrite, and send signals to other neurons with a long cable-like part called the axon. An axon can be up to a meter long. In some neurons, axons are covered with a thin layer of fat called myelin, which acts as an insulator.
What part of the neuron receives information from other neurons to relay it to the cell body?Dendrites. Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface area of the cell body. These tiny protrusions receive information from other neurons and transmit electrical stimulation to the soma.
What relays signals across the synapses between neurons?A neurotransmitter is a chemical that relays signals across the synapses between neurons. Neurotransmitters travel across the synaptic space between the terminal button of one neuron and the dendrites of other neurons, where they bind to the dendrites in the neighbouring neurons.
