Which part of a neuron receives signals?

The part of a neuron that receives signals is the dendrites. Dendrites are tree-like structures that extend from the neuron and are primarily responsible for gathering information from other neurons and sensory receptors. They have specialized receptors that bind to neurotransmitters released from neighboring neurons, allowing for the transmission of signals across the synaptic gap.

When a neurotransmitter binds to receptors on the dendrites, it can generate an electrical impulse within the neuron. This process is crucial for neural communication, as it determines whether the neuron will generate its own signal, known as an action potential, which then travels down the axon to transmit the information to other neurons or muscles.

The other parts of a neuron have different functions: the cell body contains the nucleus and organelles, the axon transmits signals away from the cell body to other neurons or muscles, and the myelin sheath serves as an insulating layer that enhances the speed and efficiency of signal transmission along the axon.
