Neural Cells Flashcards
The majority of immune cells cannot
Cross the blood-brain barrier
Conduction potential velocity increases with
- Increased axon diameter
- Myelination
Gangliosides are found on
Schwann Cells
What is the function of Ependymal cells?
They help form the barrier that holds in and produces CSF
What is the most common cell type in the brain?
Astrocyte
What are the functions of Astrocytes?
- Structural
- Metabolic
- Regulatory
- Repair
The majority of the nervous system arises from the
Ectoderm / Neural Crest Cells
Microglia arise from
Monocytes
Monocytes arise from which germ layer?
Mesoderm
The microglia arise from which embryonic layer?
Mesoderm
The DRG contains pseudounipolar neurons, in which
Two branches of a single axon act as one
Astrocytes are involved in the
Strengthening the blood brain barrier
Which term describes the cell membrane potential of a neuron at rest?
Polarized
What is the function of the sodium-potassium pump?
- Pulls K+ ions in
- Removes Na+ ions from cell
When a membrane is at rest, sodium ions are more concentrated
Outside of the neuron
