| Question | Answer |
| Name the membrane that covers the frontal lobe and the three layers comprising them | The meninges are the three layers that envelop the brain and spinal cord. The meninges are the Pia, arachnoid and dura mater |
| Name the liquid between 2 of these membrane layers. | Cerebrospinal fluid fills the subarachnoid space between the arachnoid mater and pia mater. |
| How does Cerebrospinal fluid differ from serum | Cerebrospinal fluid contains a lot less protein near to 1% |
| What are the correct terms for the crests and the grooves on the surface of the brain | The crests are called Gyri and the grooves are called sulci. |
| Name the following brain lobes | 1.Frontal 2. Parietal 3.Occipital 4.Cerebellum 5.Temporal |
| Areas on the brain surface associated with various sensations and actions have been mapped name them | 1.Brocas Area 2.Primary Motor Cortex 3. Central Sulcus 4.Primary Sensory Cortex 5. Visual Cortex 6. Auditory Cortex |
| Which plane of section is viewed here | This is the Mid Sagittal Plane |
| Name the regions labelled 1-11 | 1. midbrain 2. pons 3. medulla 4. cerebellum 5. occipital lobe 6. parietal lobe 7. frontal lobe 8. corpus callosum 9. basal ganglia 10. internal capsule 11. thalamus |
| Which section of the brain is this? | This is the coronal section of the brain |
| Name the areas labelled 1 and 2 and the technique used to get this image | 1.Lateral ventricle 2. Corpus Callosum and Magnetic Resonance Imaging MRI |
| What is the most abundant cell body in area 2 | Oligodendrocyte |
| What is the correct term for the cleft at * | Central Fissure |
| What is this? | This is a Golgi-stained transverse section of spinal cord with attached root. |
| Name structures 1-6 | 1. motor neuron 2. efferent nerve fibres 3. dorsal root ganglion neuron 4. White matter 5. Grey matter 6. afferent nerve fibres. |
| Which 2 numbers indicate the locations of the upper and lower motor neurons in the opening of the mouth | 3. Upper motor cortex and 10. lower pons |
| Which motor tract is involved in the opening of the mouth | Corticobulbar tract |
| State 3 of the numbered locations that contain neurons involved in controlling the action of opening your mouth | 1. Pre frontal Cortex 5. Cerebellum and 8. Basa, Ganglia |
| What is this picture of? | This picture is a mouse sciatic nerve transverse section and shows the white matter. |
| What is the most abundant type of cell body in this picture | Schwann Cell |
| What material forms the dark structures with one labelled red * | Myelin |
| What type of sensation is conveyed by nerve fibres in area R | Pain,itch |
| What type of sensation is conveyed by the nerve fibre marked blue * | Touch, proprioception |
| Identify all the labelled structures | 1.Mitochondria 2.Active zone 3.Synaptic vesicles 4.Presynaptic cell 5.Postsynaptic cell |
| Which of the 2 synapses arrowed is excitatory and which inhibitory and why? | A is excitory and B inhibitory because A is an asymmetric synapse with a post synaptic density |
