Question

question 5
what function does a dendrite serve?

○ they receive most of the synaptic contacts from other neurons.
○ they serve as a protective layer over the axon.
○ they release chemicals into the synapse.
○ they are a semipermeable membrane that encloses the neuron.

Explanation:

• Analyze each option:
• Option 1: Dendrites are the parts of a neuron that receive signals (synaptic contacts) from other neurons. This matches their function.
• Option 2: The protective layer over the axon is the myelin sheath, not dendrites. Eliminate.
• Option 3: Neurotransmitters (chemicals) are released from the axon terminal, not dendrites. Eliminate.
• Option 4: The semipermeable membrane enclosing the neuron is the cell membrane, not specific to dendrites. Eliminate.

Answer:

A. They receive most of the synaptic contacts from other neurons.
