Exam 5: Protecting and Maintaining the Adult Nervous System

Point out biological problems would be difficult to solve if the "brain-in-a-vat" experiment were ever tried in real life. Some of these would include:

Choose whether the event below describes necrosis or apoptosis. -__________ minimizes damage to neighboring cells

Choose whether the event below describes necrosis or apoptosis. -__________ cell ruptures and releases contents in an uncontrolled manner

Differentiate between oligodendrocytes and Schwann cells.

Which of the following can weaken barriers in the brain?

There is considerable evidence that immune cells can enter the CSF. One theory as to why these same cells cannot readily cross into the brain parenchyma is because ____________________ prevent their crossing or reduce their effectiveness.

What is true of the lateral ventricles?

Decide which of these cells (NEURON, NON-NEURON, or BOTH) is described by each statement below. _______________ can employ a variety of metabolic pathways to synthesize glucose _______________ uses glycolysis and oxidative phosphorylation to generate ATP _______________ must uptake glucose from extracellular environment _______________ can use lipids and amino acids as an energy source

Necrosis

The subarachnoid space lies between the arachnoid membrane and the _________________.

Identify the problem associated with an understanding of adaptive immunity as it relates to neural tissue.

The brain volume significantly expands over the first 9 months after a human is born. What is most likely responsible for this change in brain volume?

Predict what would happen in the arachnoid membrane if the cells of the arachnoid barrier were exposed to a drug that limited their ability to form membrane-bound vacuoles.

Examine Figure 23B. In the text As a result of blockage, which of the following has happened?

In order to determine whether a cell has recently divided

Which of the following is true of the innate immune response?

What is true about a subdural hematoma?

Match the event with the type of immunity -________________ slow response to a novel (new) antigen

Place the following events in order regarding the regulation of blood flow to active brain regions by writing 1-4 in the blank spaces. _____ many neurons become active, releasing glutamate as a neurotransmitter _____ calcium levels rise in astrocyte endfeet _____ blood vessels dilate _____ astrocytes detect glutamate via glutamate receptors

Identify which of the following is true of the adaptive immune system?
