Other questions in this quiz
2. What effect does an enriched environment have on the cerebral cortex?
- It causes the cortical neurons to thicken as the infant is exposed to more sights and sounds.
- The cerebral cortex increases in width with age allowing the infant to absorb more information
- Aids in developing muscle tone and balance
- Aids in developing the infants vision and attention management
3. What is apoptosis and why does it occur?
- Buildings of connections between synapses to 'finely tune' the brains 'circuitry'
- Increase of brain surface; to increase cell stimulation
- Programmed cell death of poorly stimulated neurons; increases efficiency of functioning
- The formation of sulci and gyri to accommodate more neurons
4. What does the process of myelinisation do/improve?
- Produces nerve cells at a rate of 250,000pm
- Adds to the weight of the total brain
- Insulates the cell and improves synaptogenesis (cell communication)
- Allows cells to acquire specialised functions
5. Which two areas govern autonomic functions as well as reflexes
- Automatic nervous system and medulla
- Cerebral cortex and Spinal cord
- Brainstem and midbrain
- Spinal cord and midbrain
