What is the primary function of a dendron?

• A. To transmit impulses away from the cell body
• B. To carry impulses towards the cell body of a neuron
• C. To protect the neuron from damage
• D. To store neurotransmitters

Answer: (B)

The primary function of a dendron is to carry impulses towards the cell body of a neuron. Dendrons, which are extensions of the neuron's cell body, play a crucial role in receiving signals from other neurons or sensory receptors. The structure of dendrons is designed to increase the surface area available for synaptic contacts, allowing them to effectively integrate and process incoming information. This helps in transmitting the electrical impulses, known as graded potentials, that lead towards the neuron's cell body, where they can be processed and possibly result in an action potential if the threshold is met. Understanding this role highlights the importance of dendrons in the overall function of the nervous system, as they facilitate communication between neurons and contribute to the processing of information.
