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.
