The dendrites and cell body. Incoming signals from other neurons are received here.
A dendrite (or often a small protrusion from it called a dendritic spine) is the structure of a neuron that is usually the input to the neuron. A synapse is what makes the input to a neuron, via chemical messengers called neurotransmitters. And inputs to a neuron cansometimes be made to the soma (body) of a neuron, or even to the axon. But the dendrites are the "normal" input structures.
Yes, dendrites are the input structures of a neuron.

It is a neuron that is at its resting potential, not stimulated by input from other neurons.
Axons are the output element of a neuron, and dendrites are the input elements of a neuron.
about 10 dendrites
Neural input happens at the dendrites (dendritic tree) of the neuron, but some neurons, notably the sympathetic, can receive input at the axon hillock (where the axon leaves the soma).
The axon hillock and the initial segment
The simplest sense, the all-or-none principle of neuronal firing means that a neuron will either fire or it won't, there is no "half" firing. When a neuron receives excitatory input.
False
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
