Karten in diesem Stapel (38)
- 1Golgi StainTechnique used to visualise silhouettes of individual cells
- 2Nissl StainTechnique used to visualise cell bodies of a selected area
Cresyl Violet is the dye used to stain - 3Electron MicroscopyMethod of scanning a cell to see very detailed neuronal structure using electron-absorbing substances to project onto a photographic film
- 4Neuroanatomical Anterograde Tracing TechniquesForward tracing paths of axons projecting AWAY from cell bodies that are taken up by cell bodies
- 5Neuroanatomical retrograde tracing methodsBACKWARD tracing that investigates pathways of axons INTO the cell bodies
- 6Vertebrate nervous system three axesAnterior - Posterior
Dorsal - Ventral
Medial - Lateral - 7Brain DorsalUp
- 8Brain VentralDown
- 9Brain PosteriorRight
- 10Brain AnteriorLeft
- 11SuperiorTop of primate head
- 12InferiorBottom of primate head
- 13Proximal DirectionCloser to CNS
- 14Distal DirectionFurther away from CNS
- 15Grey MatterMainly composed of cell bodies and unmyelinated interneurons
- 16Spinal Cord White MatterLargely of myelinated axons
- 17Major Divisions of the Brain1. Telen (top)
2. Dien
3. Mesen
4. Meten
5. Mylen - 18TelencephalonLargest division of the human brain and involves the most complex processes
Cerebral Cortex (four lobes)
Fissures
Limbic System
Basal Ganglia - 19Cerebral CortexConvoluted gray matter with fissures that divide the hemispheres into lobes
- 20Gyrusridges between fissures and sulci
- 21Postcentral Gyrussensations of the body
- 22Superior Temporal Gyrushearing and language
- 23Inferior Temporal Cortexidentifies complex visual patterns
- 24Medial temporal cortexcertain kinds of memory
- 25Neocortexnew cortex, makes up 90% of human cerebral cortex. Consists of 6 layers (I to VI)
- 26Pyramidal Cellslarge, multipolar neurons with large dendrites and a very long axon
- 27Stellate Cellssmall, star-shaped interneurons (little or no axon)
- 28Hippocampus(Part of Myelencephalon)
plays a part in memory (particularly spatial location)
Located in medial temporal lobe - 29Limbic SystemLimbic means 'ring' - circles the thalamus
regulation of motivated behaviours
amygdala
cingulate cortex
septum - 30AmygdalaInvolved in emotion - particularly fear
- 31Basal GangliaRole in performance of voluntary motor responses
Caudate forms a circle with a centre called the putamen
Together they are the striatum - 32DiencephalonComposed of the thalamus and hypothalamus
- 33ThalamusLocated on top of brain stem
Involved in sensory and motor relay and regulation of consciousness and sleep - 34Thalamic sensory relay nucleireceive signals from sensory receptors and transmit them to appropriate areas of sensory cortex
- 35Hypothalamusplays a role in regulation of several motivated behaviours(eating sleep and sexual behaviours)
regulating the release of hormones from the pituitary gland - 36Mesencephlanondivided into tectum and tagmentum
- 37Metencephlanoncerebellum and pons
- 38Mylencephalonor Medulla
tracts carrying signals between the rest of the brain and the body
