Question

match the word on the left to the correct definition/function on the right.
dendrite choose
axon choose
myelin sheath choose
synapse choose
cell body choose
options (from dropdown): that receives messages from other neurons, the gap that a message has to cross to get from one neuron to the other, a fatty substance that helps to speed up the transmission of the message, produces energy that fuels the activity of the cell, sends messages to other neurons

Explanation:

• Dendrite: In neuron structure, dendrites are the parts that receive signals (messages) from other neurons.
• Axon: Axons are responsible for sending (transmitting) messages to other neurons (either other neurons, muscles, or glands).
• Myelin Sheath: It is a fatty (lipid - rich) substance that insulates the axon and helps in speeding up the transmission of neural impulses (messages).
• Synapse: It is the small gap (junction) between two neurons (or a neuron and an effector cell) across which a message (neurotransmitter - carried signal) has to cross.
• Cell Body: The cell body (soma) of a neuron contains the nucleus and other organelles and is responsible for producing energy (through processes like cellular respiration in mitochondria) that fuels the cell's activities.

Answer:

• dendrite: that receives messages from other neurons
• axon: sends messages to other neurons
• myelin sheath: a fatty substances that helps to speed up the transmission of the message
• synapse: The gap that a message has to cross to get from one neuron to the other
• cell body: produces energy that fuels the activity of the cell
