Which of the following describes dendrites?

Correct option is A

• Dendrites are the short, branched extensions of a neuron that receive signals from other neurons or sensory receptors. These branches increase the surface area for communication and allow dendrites to receive more information.
• Dendrites play a key role in transmitting electrical impulses to the cell body of the neuron.

• They are typically short and have a highly branched structure to increase their surface area for better signal reception.

• The branching allows the neuron to connect to many other neurons, forming networks within the brain and nervous system.

• Dendrites are essential for synaptic transmission, where neurotransmitters from other neurons are received.

• They are found on the cell body of neurons, extending outward to form connections with axons of other neurons.

• Dendrites help in carrying the signals towards the cell body and are vital for the functioning of the nervous system.

Additional Information:

• Long and branched: While some axons may have long branches, dendrites themselves are typically short and branched.

• Short and unbranched: Dendrites are generally not unbranched, as their branched structure is critical for their function.

• Long and unbranched: This description is typically used for axons, not dendrites. Axons are long and transmit signals away from the cell body.
