Question

1. what part of the brain helps turn short - term memories into long - term memories?

○ cerebellum
○ hippocampus
○ brainstem
○ spinal cord

1. what are neurons?

○ muscles in the brain
○ brain cells that send electrical messages

Explanation:

Question 1

To determine the brain part for converting short - term to long - term memories, we analyze each option:

• Cerebellum: Mainly for motor control and balance, not memory conversion.
• Hippocampus: Known to be crucial for the formation and conversion of short - term to long - term memories.
• Brainstem: Regulates basic life functions like breathing and heart rate, not memory conversion.
• Spinal cord: Part of the peripheral nervous system for signal transmission, not involved in memory conversion.

To define neurons, we analyze the options:

• Muscles in the brain: Neurons are not muscles; muscles are for movement.
• Brain cells that send electrical messages: Neurons are specialized cells in the nervous system that transmit electrical and chemical signals.

Answer:

B. Hippocampus
