Which of the following IS part of the peripheral nervous system?
The nerves
A person comes into the emergency room with a head injury. After the injury they have problems being aware of their body if they close their eyes. Given what you know about neuroanatomy, which of the following brain regions was most likely damaged?
Parietal Lobe
A person is diagnosed with a primary brain tumor. Which of the following cells COULD NOT have produced the brain tumor?
Neuron & Schwan cells
Animal brains are labeled how?
dorsal (top), ventral (bottom), rostral (front), caudal (back) for the head.
Human brains are labeled how?
superior (top), inferior (bottom), anterior (front), posterior (back) for the head.
If the neural tube does not form correctly, which of the following would NOT develop normally?
Ventricles & Brain
Which type of study best describes a research study in which a subject’s performance on a cognitive task while in a brain scanner is compared with the age of the subject?
Correlational
Which of the following is NOT CORRECT about ASYMMETRICAL cell division?
a. It serves as a way for progenitor cells to make cells of the peripheral nervous system
b. It serves as a way for one progenitor cell to divide into two additional progenitor cells
Which of the following is an example of a metaphor for the function of radial glia?
A ladder
True or false: Neurotrophic factors are toxic to neurons?
False
Based on what you how about the function of different brain structures, direct damage to which of the following would MOST likely to be fatal immediately/quickly? Hindbrain, Forebrain, Midbrain
Hindbrain- basic functions, such as keeping your heart beating
During development, if you isolate a neuron (i.e., put it somewhere ‘by itself’) and it does NOT differentiate into a specific type of neuron, this would indicate that the neuron uses which type of cell differentiation?
Chemicals released from neighboring cells.
In an experimental manipulation, before a group of rats were timed running in a maze, half the rats in a study were given caffeine and half were not. In this study, what is the dependent variable?
How long it takes the rats to run through the maze.
True or false: If you damage the dorsal part of your spinal cord, you would have problems controlling your muscles?
False
True or false: the Ventricular zone contains mature (differentiated) neurons.
False
