Biology Quiz

What do the nervous system and endocrine system help maintain?

• Metabolism

• Homeostasis

• Digestion

• Respiration

How does the nervous system respond to different stimuli?

• Through chemical reactions

• Via electric impulses (action potentials)

• By releasing hormones

• Through physical barriers

What does the nervous system allow for?

• Perceptions, movements, behaviors, and memories

• Blood circulation and oxygen transport

• Nutrient absorption and digestion

• Hormone synthesis and release

What are the two main types of cells that compose the nervous system?

• Neurons and myocytes

• Neurons and neuroglia

• Astrocytes and oligodendrocytes

• Erythrocytes and leukocytes

How many pairs of cranial nerves are there?

• 10 pairs

• 12 pairs

• 31 pairs

• 33 pairs

How many pairs of spinal nerves does the human body have?

• 12 pairs

• 24 pairs

• 31 pairs

• 33 pairs

What is the function of sensory receptors in the nervous system?

• To produce hormones

• To regulate temperature

• To pick up internal and external impulses

• To support the neurons structurally

What type of neurons carry information into the Central Nervous System (CNS)?

• Motor (efferent) neurons

• Sensory (afferent) neurons

• Interneurons

• Effector neurons

What is the role of interneurons in the nervous system?

• They carry information out of the CNS to the effectors.

• They detect internal and external stimuli.

• They are involved in the conscious awareness of stimuli.

• They respond to stimuli by muscle contraction or glandular secretion.

What is the primary function of motor (efferent) neurons?

• Carrying information into the CNS

• Processing information within the CNS

• Responding to stimuli by muscle contraction or glandular secretion

• Detecting internal and external stimuli
