B & C
All answers listed
What is the name of the neuroglia that doesn't allow substances to cross the blood brain barrier?
Oligodendrocytes
Microglia
Astrocytes
Ependymal cells
Which neurotransmitter regulates muscle tone and emotional responses?
Acetylcholine
Dopamine

Epinephrine
All of the following are true about grey and white matter in the spinal cord, except:
Regions called horns contain grey matter
Grey matter passes information up and down the spinal cord
White matter is arranged in columns
Tracts consist of white matter
Each dermatome sends sensory signals through
A single left spinal nerve or right spinal nerve, but not both
A single nerve plexus
A segment of the spinal cord that corresponds to a plexus
A single pair of spinal nerves
Why can spinal reflexes occur more quickly than premeditated actions?
Reflexes utilize different motor neurons
Reflexes actions do not involves the central nervous system
The signal for spinal reflex is processed in the spinal cord rather than the cerebrum
Sensory information travels faster during a reflex action
The function of the medulla oblongata involves controlling involuntary functions such as respiration, digestion, circulation with some contribution to emotions.
The main functions of the midbrain are all except
Vision
Hearing
Motor control
Smell
Thermoregulation
Alertness

Thalamus
Pons
Medulla
Somewhere in the brain

2, 4, 5, 10
1, 2, 3, 8
Sympathetic nerves arise from the:
Thoracic and lumbar spinal cord
Brain stem and sacral spinal cord
Cervical and thoracic spinal cord
Cerebrum and brain stem
Meissner corpuscles can detect all of the following, except
Pressure

The somatic nervous system (SNS) is different from the autonomic nervous system (ANS) in which way?
SNS nerves carry only motor signals
SNS motor neurons do not synapse at ganglia
The SNS is responsible for all muscle tissue contraction in the body
The SNS does not relay tactile sensory information
