Brain Anatomy
Across
- 2. The long part of a neuron by which the cell sends information
- 5. A portion of the brain involved in creating and filing new memories.
- 7. The study of how environmental factors like diet, stress and post-natal care can change gene expression
- 10. The boundary separating the inside contents of a cell from its surrounding environment.
- 12. Is involved in attention, emotional responses, and many other functions.
- 14. The brain’s “fear hub,”
- 15. A change in the code for a gene, which may be harmless or even helpful, but sometimes give rise to disabilities or diseases.
- 16. A structure within a cell that contains DNA and information the cell needs for growing, staying alive, and making new neurons.
- 18. The substance filling a cell, containing all the chemicals and parts needed for the cell to work properly.
- 19. neurotransmitter that regulates many functions, including mood, appetite, and sleep.
- 20. nerve cell that is the basic, working unit of the brain and nervous system,
- 21. Transmission of signal from the cell body to the synaptic terminal at the end of the cell’s axon.
- 23. point of contact for receiving impulses on a neuron, branching off from the cell body.
- 24. A chemical produced by neurons that carries messages to other neurons.
Down
- 1. neurotransmitter involved in controlling movement, managing the release of hormones, and aiding the flow of information
- 3. An electrical communication signal sent between neurons by which neurons communicate with each other.
- 4. most common neurotransmitter in a person’s body, which increases neuronal activity,
- 6. highly developed area at the front of the brain that, in humans, plays a role in executive functions
- 8. A segment of DNA that codes to make proteins and other important body chemicals.
- 9. axis A brain-body circuit which plays a critical role in the body’s response to stress.
- 10. Contains the nucleus and cytoplasm of a cell.
- 11. The “recipe of life,”
- 13. imaging technique that uses magnetic fields to take pictures of the brain’s structure.
- 17. tiny gap between neurons, where nerve impulses are sent from one neuron to another.
- 22. network of neurons and their interconnections.
