What do excitatory neurotransmitters do to the likelihood of the postsynaptic neuron firing an action potential?

They increase the likelihood

They decrese the likelihood

They dont change the likelihood

They first decrease and then increase the likelihood

The myelin sheath serves to:

Speed up action potential propagation

Two of these answers are correct

Increase the size of the action potential

Allow the neural signal to change direction

The frontal lobe has three regions

Some information from the visual cortexis projected to the temporal lobe

The primary somatosensory cortex is located near the primary motor cortex

Someone with Wernicke's aphasia has difficulties with the production of speech

Damage to the basal gangia is implicated with Huntington's disease

The amygdala

Is part of the hypothalamus

Produces hormones for sexual differentiation

Two of these answers are correct

Is involved in positive emotions such as laughter

Is involved in fear, anger and disgust

Axons carry

Information to the dendrites

Information to the nucleus

Information away from the glial cells

Information away from the cell body

The multipolar neuron consists off

1 axon and many dendrites branching from the soma

1 axon and 1 dendrite branching from the cell body

1 axon extending from the soma and no dendrites

Which "type" of neuron receives messages from sensory organs and delivers them to the CNS?

Which of the following statements about the spinal cord is true?

Two of these answers are correct

It is part of the CNS

Only transports motor information to the muscles

It has a core of grey matter surrounded by white matter

Which lobe of the brain is involved in touch and sensation?

Frontal

Temporal

Parietal

None of these lobes

Which of the following statements about the autonomic nervous system is not true?

Sympathetic nervous system is fight or flight

None of these answers is true

Associated with involuntary control of body movement

Neurons are excitatory only

Which of the following is not true

ECT is a form of brain imaging

Galen believed in "animal spirits"

Ions cross freely the membrane of a neuron at rest

There are 12 cranial nerves

The neuron membrane is a lipid bilayer

An action potential occurs when

Depolarization causes voltage-gated calcium channels to close

Depolarization causes voltage-gated sodium and potassium ion channels to open

Depolarization causes voltage-gated sodium channels to open and potassium channels to shut

Hyperpolarization causes voltage-gated sodium and potassium ion channels to open
