Lecture 2- Forebrain Flashcards
Types of Glia in the CNS
___________ have a “star like” appearance and can be seen at CNS synapses
maintain an appropriate chemical environment for neuronal signaling
formation of the blood barrier: prevents circulating immune cells, molecules, or pathogens that could interfere with neural function from entering the brain
secrete substances that influence the construction of new synaptic connections
Astrocytes
Types of Glia in the CNS:
________ secretes the myelin sheath
Oligodendrocytes
Types of Glia in the CNS:
________ become resident in the brain during early development and integrate into neural tissue
similar to macrophages
secrete signaling molecules (cytokines) in immune system
modulate local inflammation/influence whether cells live or die
Microglia
Types of Glia in the CNS:
_________ cells produce CSF
Ependymal

post-central
A1: is the primary ______ cortex which helps us _____
auditory
hear
V1: is the primary _____ cortex which helps us see
visual

Brain lateralization is _______ body control and is functionally _________ ex. metacognition
Ex. The R side of our brain controls left field vision and motor skills (vice versa)
contralateral
asymmetric
