Dendrites are branching extensions of C) neurons.
Dendrites are branching extensions of neurons. Neurons are the basic structural and functional units of the nervous system, responsible for transmitting information through electrical and chemical signals. The main components of a neuron include the cell body (or soma), axon, and dendrites.
Dendrites are specialized extensions that protrude from the cell body of a neuron. These dendritic branches receive signals from other neurons or sensory receptors. When a neuron is stimulated, an electrical impulse travels down the axon, the long projection of the neuron, and releases neurotransmitters at the axon terminals. These neurotransmitters then bind to receptors on the dendrites of neighboring neurons, allowing the signal to be transmitted from one neuron to another.
