Quiz-Nervous System (Grade 8-9)

Which part of the nervous system is known as the body's processing center?

• Peripheral Nervous System (PNS)

• Sensory Nervous System

• Central Nervous System (CNS)

• Autonomic Nervous System

What are the primary components of the CNS?

• Brain and spinal cord

• Nerves and muscles

• Sensory receptors and neurons

• Bones and muscles

The PNS is mainly responsible for:

• Processing information

• Interpreting sensory input

• Relaying signals between the CNS and the body

• Protecting the brain and spinal cord

Where are sensory neurons located?

• In the brain

• Dorsal root ganglion of the spinal nerve

• Ventral root ganglion of the spinal cord

• Muscles

Motor neurons are located in the:

• Skin

• Dorsal root ganglion

• Ventral root ganglion of the spinal cord

• Sensory organs

What type of neuron carries impulses from sensory organs to the CNS?

• Motor neuron

• Sensory neuron

• Interneuron

• Bipolar neuron

The cerebrum's frontal lobe is primarily involved in:

• Visual processing

• Cognitive functions like planning and reasoning

• Balance and coordination

• Regulating breathing

Which part of the cerebrum is responsible for sight and visual memory?

• Frontal lobe

• Parietal lobe

• Temporal lobe

• Occipital lobe

The parietal lobe is involved in:

• Hearing and smell

• Processing touch and spatial awareness

• Balance and coordination

• Autonomic functions

What is the primary function of the cerebellum?

• Thought and memory

• Balance, posture, and coordination

• Sight and visual processing

• Breathing regulation
