Brain bee - cells

What are efferent vs afferent neurons?

Answer explanation

Afferent - sends info to brain from the PNS

Efferent - sends into the body from the CNS

List the 6 glial cells

Answer explanation

- Astrocytes (CNS only)

- Ependymal cells (CNS only)

- Microglia (CNS only)

- Oligodendrocytes (CNS only)

- Schwann cells (PNS only)

- Satellite cells (PNS only)

What is grey matter made of?

• Neuron axons
• Neuron cell bodies (nuclei)

What is white matter made of?

• Neuron axons
• Neuron cell bodies (nuclei)

Why is white matter white?

• Myelin sheaths

• Cytoskeleton

Components of a neuron

• Dendrites

• Cell body

• Axon

• Terminals

• Myelin sheath

Function of astrocytes?

Answer explanation

- Transport of nutrients/waste from neurons

- Manages microenvironment

- Astrogliosis

- Acts as a buffer reserve of energy

- Controls blood flow in capillaries
