Nervous System Quiz

What pathway takes a signal from the sensory organs to the brain?

• Afferent/ Sensory pathway

• Motor Pathway

• Efferent neuron

• Microglia

What ion is needed to depolarize the neuron and cause the action potential

• potassium

• calcium

• sodium

Chemicals contained in tiny vesicles in the axon terminal

• neurotransmitters

• axon terminals

• motor neurons

• efferent nerves

Carry impulses to the CNS from the sensory receptors located all over the body (select all correct answers)

• motor neurons

• sensory neurons

• efferent neurons

• afferent neurons

Allows us to consciously control our skeletal muscles

• somatic / motor neurons

• autonomic / voluntary neurons

• sympathetic nervous system

• IDONTKNOWACARDIA

The structure that transmits the nerve impulse away from the cell body and towards the next nerve cell

• axon

• dendrite

• cell body

The master controlling and communicating system of the body

• Urinary system

• Immune System

• Nervous System

• Muscular System

The part of the nervous system that lies outside of the CNS

• Central nervous system

• Reflex nervous system

• autonomic nervous system

• Peripheral nervous system

Carries impulses from the CNS to effector organs, the muscles and glands

• afferent neurons

• motor neurons

• pain receptors

• brain stem

Regulates events that are automatic or involuntary, such as heartbeat, blood flow, and sweat glands
