- 1Name the 4 lobes each hemisphere of the brain is divided into?Frontal, Parietal, Occipital, Temporal
- 2What is neural plasticity?It is the ability of neutrons to change their structure and function as a result of environmental and genetic factors
- 3What is hemispheric lateralizationThis refers to the relatively large location of a certain function on one hemisphere or the other
- 4What nervous system prepares your body for flight or fight?The sympathetic nervous system
- 5Name the parts of the peripheral nervous systemAutonomic, Somatic, Sympathetic, Parasympathetic
- 6What part of the brain allows or prevent messages being passed on to the higher brain centresReticular formation
- 7Name the parts of the central nervous systemThe brain and spinal chord
- 8What is GABA? Gamma-Amino Butyric acidIt inhibits nerve transmission in the brain, calming nervous activity.
Alcohol as an agonist stimulates the activity of GABA - 9Chemicals that produce changes in consciousness, emotion, and behaviour are called what drugs?Psychoactive drugs
- 10At rest a neutron has more ---- ions outside and more ---- ions insideNa, K
- 11The neurotransmitter Endorphin is the best known...NEUROMODULATOR: they have a more widespread and generalized effect on synaptic transmissions.
It increases feeling of well-being and reduces pain. - 12PET (Positron emission tomography) scans are able to measure:neurotransmitter activity, metabolism, blood flow, brain activity
- 13The neurotransmitter acetylcholine is involved in?Memory and muscle activity
- 14Which disorder are related to the malfunctioning of the neurotransmitter serotonin?Depression, sleeping, eating disorders
- 15Functions of the cerebellum?muscle movement coordination, memory and learning
- 16Limbic system?Coordinates motivational and emotional urges, involved in memory, two key structures are hippocampus and amygdala
- 17Glial cells?Support nerve cells, absorb toxins, produce nutrient for neurons.
Non-neuronal cells that maintain homeostasis, form myelin, and provide support and protection for neurons in the central nervous system and peripheral nervous system.
