Neuroanatomy Quiz: Test Your Knowledge
Welcome to the Neuroanatomy Quiz! This quiz is designed to help you evaluate your understanding of the fundamental concepts of neuroanatomy based on slides 20-32.
Participants will encounter a variety of questions covering topics such as:
- Basic brain structures
- Glial cells and their fun
ctions - Protective membranes of the brain
- Brain divisions and their significance

Fatty structures that wrap around the neurons, Schwann cells
Fatty structures that send projections out to wrap around axons, Oliodendrocytes
Which one of the following statements is untrue for glial cells?
They help regenerate neurons
They facilitate the conduction of messages down the neuron
They are innate structures that protect the axon

True
False
What are the physical structures that protect the brain from mechanical injuries? (numerous answers)
Skull

The blood brain barrier
The blood brain barrier provides chemical protection for our brains. It cannot combat mechanical injuries but it can prevent harmful chemicals from entering the brain.
The blood brain barrier provides chemical protection for our brains. It cannot combat mechanical injuries but it can prevent harmful chemicals from entering the brain.
The blood-brain barrier forms tightly packed cells along the blood vessel walls of the central nervous system in order to prevent entry of many large molecules. This can be helpful as it prevents harmful chemicals from damaging the brain but can also serve as unhelpful when trying to introduce helpful molecules into the brain to combat disease/ disorders.
