1. Two almond-shaped nuclei deep within the temporal lobe, involved in decision-making, memory, and emotional responses, particularly negative emotions.

2. The ventricles communicate via five foramina. This lateral foramen is a paired structure, that allows the CSF to flow between the ventricles and subarachnoid space.

3. A long slender projection of a neuron, that conducts electrical impulses, known as action potentials, to other neurons, muscles, and glands.

4. The brainstem is an area located at this part of the brain, that contains structures vital for involuntary functions such as heartbeat and breathing.

5. When both sides of the brain are activated, it is described as being this activated, ensuring good balance, and good motor skills.

6. This lies on top of the pons, behind the brain stem. It helps control posture, balance, and the co-ordination of voluntary movements.

7. This is the largest part of the brain, divided into left and right hemispheres. It controls intelligence, memory, personality, emotion, speech, and ability to feel and move.

8. This nucleus, part of the medulla oblongata, carries fine touch and proprioceptive information to the thalamus and cerebellum.

9. The CNS processes the received information, and co-ordinates and influences the activity of all parts of the bodies, of all multicellular animals, except sponges and these.

10. A chemical released in the brain that allows you to feel pleasure, satisfaction, and motivation, and helps nerve cells to send messages to each other.

11. The surface of the cerebrum is highly irregular, composed of sulci and these folds, which increase the surface area of the cerebrum.

12. It is divided into three groups of nuclei (anterior, middle, posterior), and these three zones (periventricular, medial, lateral). It regulates the stress response, metabolism, and reproduction.

13. A substance that sheathes the axons, which gives them a distinguishable white colour.

14. The process by which new neurons are formed in the brain. Glial cells are believed to be a type of stem cell, involved in this process.

15. Nerve (cranial nerve I) that transmits information about odours, from the upper section of the nasal cavity, to these bulbs on the base of the brain.

16. Only arthropods, cephalopods, and vertebrates have a true brain. Primative structures exist in these, commonly known as velvet worms, gastropods and lancelets.

17. A stalk that attaches the cerebrum to the brainstem. It is made of a mass of nerve fibres, and there is one on each side of the brain.

18. This matter adheres to the surface of the brain, and spinal cord, respectively. It contains numerous blood vessels that nourish the surface of the CNS.

19. The autonomic nervous system controls both skeletal and smooth muscle, whether it is changing the metabolism of glucose in skeletal muscles or causing these parts of the eye to dilate.

20. The medulla oblongata is the most inferior part of the brainstem. It regulates autonomic activities related to cardiac, respiratory, this, and vasomotor functions.

21. An axon is the long part of the body of the nerve cell, that carries impulses away from the cell. These structures, that extend from the cell body, are called dendrites, and carry impulses from the synapses to the cell body.

22. The CNS consists of two organs, the brain and spinal cord. The spinal cord is a long pipe-like structure arising from the medulla oblongata, consisting of a collection of nerve fibres, running through the vertebral column of this.

23. The PNS is made up of cranial and spinal cord nerves. The nerves, known as efferent motor neurons, are those which innervate muscles with these, from the somatic nervous system.

24. Most animals that exhibit bilateral what, have a complex brin, that is located in the head, which si part of a well-developed nervous system?

25. In the CNS these are gaps, that allow signals to pass from one neuron to another, and are key to the brain’s memory function.
