Understanding the Nervous System and Cell Types

What is the primary function of parietal cells in the stomach?

• Regulate breathing

• Release histamine

• Produce stomach acid

• Coordinate muscle movement

Which cells are known for their role in the inflammatory response by releasing substances like histamine?

• Mast cells

• Neurons

• Parietal cells

• Skeletal muscle cells

What is the main structural feature of skeletal muscle cells?

• Production of myelin sheath

• Single nucleus with no filaments

• Multiple nuclei and filament structure

• Ability to release neurotransmitters

Which part of the nervous system includes the brain and spinal cord?

• Peripheral nervous system

• Central nervous system

• Autonomic nervous system

• Somatic nervous system

What is the role of the cerebellum?

• Processing sensory information

• Coordination of balance and movement

• Regulation of heart rate

• Sleep and wake cycle management

Which system is activated during a 'fight or flight' response?

• Sympathetic system

• Central nervous system

• Peripheral nervous system

• Parasympathetic system

What is the primary function of glial cells?

• Regulation of blood pressure

• Release of digestive enzymes

• Support and protect neurons

• Muscle contraction

What happens during an action potential in a neuron?

• Permanent opening of sodium channels

• Neurotransmitters are digested

• Decrease in neuron's resting potential permanently

• Rapid change in electrical charge along the axon
