Which of the following statements is not true?
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
3 axons extending from the soma and many dendrites
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

Efferent neuron
Interneuron
Afferent neuron
Motorneuron
None of these answers are correct
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

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

The cochlea is a snail-shaped structure of the middle ear
The intracellular fluid is on the inside of the neuron
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
