1. Neuros an Glia Flashcards
Phrenology
The idea that personality traits could be read based on bumps on your skull (prevalent in 19th century)
Brodmann’s areas
52 areas divided based on cell types since 1903
Name all finally developed sections of the brain
Medulla, ponds, cerebellum (hindbrain), midbrain, diencephalon and telencephalon (forebrain)
metencephalon
ponds and cerebellum
myelencephalon
medulla
prosencephalon
diencephalon and telencephalon
Explain the ventricular system
Consists of the lateral ventricle (big ones in the middle), drains through the foramen of monroe into the 3rd ventricle in the diencephalon and drains into the 4th ventricle (between ponds/medulla and cerebellum) through the cerebral aqueduct
Gyrencephalic versus lissencephalic Brain
Wrinkled versus smooth brain
Evolution of the human brain
Overall we see a decrease in the size of the olfactory system and an increase in the size of the PFC and the temporal lobes
Important structures in the Development of the Nervous Systemin Vertebrates
The notochord, the neural tube (becomes the CNS) and the neural crest (becomes the PNS)
First neuronal cell type in development
Radial glia, but divides into Cajal-Retzius cells
Melanocytes
Melanocytes are melanin-producing neural crest-derived cells. Could be at the root for skin-related tumors
Neuron-type you can’t find in the mammalian nervous system
uni-polar neurons
bi-polar cells can be found
e.g. in the retina
