| Question | Answer |
|---|---|
| What are the 6 Neuroglia? | Astrocytes, microglia, ependymal, oligodendrocytes, satellitealls |
| What makes up the Nervous System | Central Nervous System and Peripheral Nervous System |
| What makes up the Central N.S | Spinal chord and the Brain chord |
| What makes up the Peripheral N.S | Motor Nuerons and Sensory Neurons |
| What makes up Motor Neurons | Autonomic N.S(involuntary: impulses) and Somatic N.S (Voluntary: rest/digest) |
| What makes up the Autonomic N.S | Sympathetic N.S and Parasympathetic N.S |
| What is a tract? | Bundles of processes in the Central N.S |
| What is a nerve? | Bundles of processes in the Peripheral N.S |
| What is Acetycholine | Excitatory to skeletal muscles, excitatory or inhibitory to visceral effectors |
| What is Dopamine | Excitatory or inhibitory depending on the receptor type bound |
| What is GABA | Generally inhibitory, Direct action |
| What is Glutamate | Generally excitatory, Direct action |
| What is Glycine | Generally inhibitory, indirect action via 2nd messenger |
| What is Norepinephrine | Excitatory or inhibitory depending on receptor type bond, indirect action |
| What is Serotonin | Mainly inhibitory, indirect action via second messengers, direct action at S-HT3 receptors |
| Why is Saline applied to a resting neuron? | It would provide information about how a neuron responds to the solvent solution. |
| When the neurotransmitter glutamate is applied to the neuron, how does it's activity change? | Glutamate stimulates the neuron and causes it to generate more electrical impulses |
| How does the application of two neurotransmitters, glutamate and GABA, change the activity of the Neuron? | GABA is present in high enough concentration to override the effects of glutamate |
| Do all neurotransmitters affect a neuron in the same way? | No, they have opposite effects on the neurons activity |
| What is another way to call meninges? | Arachnoid layer |
| Pia mater is? | Internal of the brain, clings to the brain |
| Periosteum? | Attached to the inner surface of the skull (Inside brain) |
| Meningal layer? | Outer covening of the brain (outside brain) folds inwards in several areas. |
| Motor output is the | Ventral |
| Sensory output is the | Dorsal |
