Quiz on the Body's Nervous System

What is the main function of the body's nervous system as mentioned in the image?

• To control voluntary muscle movements exclusively

• To maintain the body's internal environment within optimal levels/limits

• To process thoughts and emotions

• To regulate blood flow only

According to the image, how does the nervous system maintain homeostasis?

• By digesting food and absorbing nutrients

• By sensing and responding to the surrounding environmental changes

• By circulating blood throughout the body

• By filtering waste products from the blood

What is the first step in the Generalized Pathway of the nervous system's response to maintain homeostasis, as shown in the image?

• Interpretation

• Response

• Stimulus

• Effector action

What does the 'Interpretation' step in the Generalized Pathway involve according to the image?

• The contraction of muscles

• The release of hormones

• Learned and involuntary information governed by the brain and spinal cord

• The detection of environmental fluctuations

What are the effectors in the nervous system's response to maintain homeostasis as indicated in the image?

• Sensory Receptors

• Brain and Spinal Cord

• Muscles and Glands

• Sensory Neurons

What does the Central Nervous System (CNS) consist of?

• Brain and cranial nerves

• Spinal cord and peripheral nerves

• Brain and spinal cord

• Ganglia outside CNS

What is the primary function of the Central Nervous System (CNS)?

• Carries information between body organs and the CNS

• Protects the brain and spinal cord

• Coordinates incoming and outgoing information

• Surrounds and protects the cerebral and also cerebrospinal fluid

What is the role of the Peripheral Nervous System (PNS)?

• Contains nerves of the brain and the spinal cord

• Coordinates incoming and outgoing information

• Carries information between the body organs and the CNS

• Surrounds and protects the cerebral and also cerebrospinal fluid

What do somatic nerves control?

• Heart rate and digestion

• The skeletal muscles, bones, and skin

• The internal organs of the body

• Emotional responses

What are the two types of somatic nerves?

• Sympathetic and Parasympathetic Nerves

• Sensory and Motor Somatic Nerves

• Autonomic and Motor Nerves

• Central and Peripheral Nerves
