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
The medulla oblongata is responsible for:
Cognitive processing
Visual interpretation
Involuntary functions like breathing and heart rate
Voluntary movement
