The Brain and Nervous System
Across
- 2. The type of neuron that receives information from the muscles and organs within the body and transfers the messages to the central nervous system.
- 5. Combines the information from the neuron's many dendrites and sends it down the axon.
- 7. A thin extension of the cell that receives information from other cells.
- 8. The entire network of nerves located outside the central nervous system.
- 10. The nervous system that sends messages between the CNS and the internal muscles and organs to regulate automatic functions.
- 11. The nervous system consisting of the spinal cord and brain.
- 12. The thin, tube-like part of a neuron that transmits the neural information from the soma down to the axon terminals.
- 14. The nervous system responsible for carrying sensory messages to the CNS and motor messages from the CNS.
- 16. Callosum, the band of nerves that connects the left and right hemisphere.
- 17. ____________________ specialisation: the understanding that the left side of the brain controls different functions to the right side.
- 18. The type of neuron that only exists in the central nervous system.
- 19. The lobe of the brain responsible for planning, organisation, goal setting and personality.
- 20. The lobe of the brain responsible for processing visual information.
Down
- 1. An individual nerve cell that receives, processes and/or transmits information to other cells.
- 3. The main feature of this lobe is memory. It also contains the Primary Auditory Cortex.
- 4. ______________ sheath: protects the axon and enables the message to pass quickly from the soma to the axon terminals without interference from other neurons.
- 6. The long, thin bundle of nerve tissue that extends from the base of the brain to the lower back.
- 9. Primary __________________________ Cortex which is responsible for touch sensations. More space is allocated the the sensitive areas of the body.
- 13. The type of neuron that transfers the message from the central nervous system to the skeletal muscles to cause movement.
- 15. Axon _______________________ are small branches at the end of a neuron that contain neurotransmitters, which are released into the synaptic gap and are received by another neuron's dendrites.
