The correct answer is:
It is the part of a neuron that carries information to the cell body.
To understand what a dendrite is, we need to first understand the structure of a neuron. Neurons are specialized cells in the nervous system that transmit information through electrical and chemical signals.
A neuron consists of three main parts: the cell body (also called the soma), the axon, and the dendrites. The cell body contains the nucleus and other organelles necessary for the neuron's functioning. The axon is a long, thin projection that carries information away from the cell body to other neurons, muscles, or glands. The dendrites, on the other hand, are shorter, highly branched projections that receive information from other neurons and transmit it towards the cell body.
So, a dendrite is the part of a neuron that carries information to the cell body. It plays a crucial role in receiving signals and transmitting them towards the cell body for further processing.
