Where is the pyramidal decussation (decussation of the pyramids)?
Which of the following statements is NOT true regarding typical muscle fibers?
They have multiple synapses made by axons from multiple motor neurons
Where are the cell bodies for neurons that synapse with and initiate contraction of the biceps muscle in the arm?
spinal cord ventral horn
What does α-bungarotoxin bind?
Which of the following is in the wall of the lateral ventricle?
Some neurons with their cell bodies in the striatum use dopamine as their neurotransmitter. Death of these neurons results in Parkinson's disease. True or false

cerebellar granule cells
Which of the following is NOT a common symptom of cerebellar pathology?
involuntary flailing of the trunk and limbs
Which of the following nuclei receives a major input from cerebellum and sends axons that synapse with lower motor neurons?
Which of the following is a major source of axons that leave the cerebellum (i.e. output of the cerebellum)?

Which type of movement is most essential for reading a street sign when you are walking down the street?
Which is NOT true regarding the vestibulo-ocular reflex?
It requires vision for its response speed.
A condition characterized by uncontrolled oscillatory movements of the eyes that often results in decreased visual acuity is:
infantile nystagmus syndrome
Where are axons from autonomic neurons in the intermediolateral cell column of the thoracic spinal cord likely to synapse?
An injury to the upper spinal cord can result in permanent constriction of the pupil. This is due to loss of ...
sympathetic control to iris muscles
Stressful situations activate the sympathetic nervous system, which affects numerous functions. Which of the following changes would be expected with a sudden stress?
inhibition of digestion
If a person's blood pressure was too high, you might consider giving them a drug to block signaling by what neurotransmitter?
The conscious perception of bloatedness or gas in the colon involves sensory information relayed from the thalamus to what area of cortex?
Which of the following features characterize non-REM sleep?
The reticular formation is a primitive system of neurons and pathways located in all of the following structures EXCEPT the ...
The primary role of the reticulo-spinal neurons is to
maintain posture, balance and muscle tone.
Prolonged wakefulness most likely would be produced by
blocking adenosine receptors in the brain.
In healthy individuals, vasopressin and oxytocin are released into the systemic (general) circulation from ...
nerve terminals in the posterior pituitary.
A blow to the head that completely severs the pituitary stalk most likely would result in ...
loss of the milk-ejection reflex.
Which of the following are characteristics of hypothalamic control of anterior pituitary function?
Hypothalamic releasing hormones are transported to the anterior pituitary via a specialized portal vein.
Which of the following statements concerning the suprachiasmatic nucleus (SCN) is FALSE?
The SCN requires light entrainment to maintain rhythmicity.
Social jet lag ...
refers to a mismatch between your "internal clock" time and your "social clock" time.
Which of the following is a symptom of Korsakoff's Syndrome?

Post Traumatic Stress Disorder
Effective pharmacological treatment of depression would include drugs that act by ...
decreasing reuptake of serotonin from the synaptic cleft.
A patient is disoriented, displays no memory of recent events and responds to questions with complete fabrication. A brain image most likely would show degeneration of the ...
Which of the following statements is NOT true regarding the visual field?
The reading visual field is narrower than the peripheral visual field because rod photoreceptor cells are abundant only in the center of the retina.
Which of the following statements is TRUE regarding measuring the reaction time?
The first nucleus in the central nervous system that conveys the visual (image forming) information is in the diencephalon
