Question

multiple choice 2 points

what is the primary site on a neuron for receiving signals from other neurons?

the axon collaterals
the axons
the axon terminals
the cell bodies
the dendrites

Explanation:

Identify the function of each neuron structure

• Axon collaterals: Branches of an axon that allow a single neuron to send signals to multiple destination cells.
• Axons: Long, slender projections that conduct electrical impulses (action potentials) away from the neuron's cell body.
• Axon terminals: The distal ends of axon branches where neurotransmitters are released to transmit signals across synapses.
• Cell bodies (soma): The metabolic center of the neuron containing the nucleus; while they can receive some synapses, they are not the primary specialized receptive site.
• Dendrites: Highly branched, tree-like extensions from the cell body specialized to receive incoming chemical signals (neurotransmitters) from other neurons and convert them into electrical impulses.

Determine the primary receptive site

• Dendrites are structurally and functionally specialized to serve as the primary antenna-like receiving sites for synaptic inputs from other neurons.

Answer:

• The axon collaterals
• The axons
• The axon terminals
• The cell bodies
• The dendrites (Correct answer)
