//Multiple Choice


The central nervous system (CNS) consists of\: {
    =Brain and spinal cord
    ~Brain and nerves
    ~Spinal cord and nerves
    ~Nerves and sensory organs
}

The peripheral nervous system (PNS) includes\: {
    ~Brain only
    ~Spinal cord only
    =Nerves and ganglia outside the CNS
    ~Brain and spinal cord
}

What is the function of sensory neurons in the PNS? {
    =To carry information to the CNS
    ~To carry instructions from the CNS to muscles
    ~To connect neurons within the brain
    ~To store memories
}

Which part of the brain is responsible for voluntary actions? {
    ~Cerebellum
    ~Medulla
    =Cerebrum
    ~Hypothalamus
}

What connects the CNS to the rest of the body? {
    ~Brain only
    ~Spinal cord only
    =Peripheral nervous system
    ~Endocrine system
}

//True or False

The CNS is responsible for reflex actions. {T}

The autonomic nervous system is part of the CNS. {F}

The cerebellum is responsible for maintaining balance and coordination. {T}

Sensory neurons carry signals from the CNS to the muscles. {F}

The somatic nervous system controls voluntary movements. {T}

//Fill in the blanks

The __________ nervous system is responsible for processing and interpreting information. {
    =Central
    ~Peripheral
    ~Autonomic
}

The peripheral nervous system is divided into the __________ and autonomic systems. {
    ~Sympathetic
    ~Parasympathetic
    =Somatic
}

The spinal cord acts as a link between the __________ and the peripheral nervous system. {
    =Brain
    ~Sensory organs
    ~Reflex arcs
}

The autonomic nervous system controls __________ actions. {
    ~Voluntary
    =Involuntary
    ~Cognitive
}

The __________ division of the autonomic nervous system is active during stressful situations. {
    ~Parasympathetic
    =Sympathetic
    ~Somatic
}  


//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Central nervous system (CNS) -> Brain and spinal cord
=Peripheral nervous system (PNS) -> Nerves outside the CNS
=Somatic nervous system -> Controls voluntary actions
=Autonomic nervous system -> Controls involuntary actions
=Sympathetic nervous system -> Active during "fight or flight"
}
