Understanding the Central Nervous System

What are the two main components of the Central Nervous System (CNS)?

• Heart and Brain

• Spinal Cord and Peripheral Nerves

• Brain and Spinal Cord

• Brain and Nerves

Which part of the brain is responsible for controlling voluntary muscle movements?

• Cerebellum

• Medulla Oblongata

• Cerebrum

• Hypothalamus

The protective membranes that cover the brain and spinal cord are known as:

• Meninges

• Periosteum

• Epidermis

• Myelin Sheath

What is the primary function of the cerebellum?

• Regulating heart rate

• Processing sensory information

• Balancing and coordinating movement

• Controlling breathing

Which part of the CNS acts as the primary 'relay station' for sensory information?

• Spinal Cord

• Thalamus

• Pons

• Medulla Oblongata

The blood-brain barrier is important because it:

• Helps in the synthesis of neurotransmitters

• Protects the brain from harmful substances in the blood

• Regulates the flow of cerebrospinal fluid

• Facilitates the passage of oxygen and nutrients to the brain

What type of cells form the myelin sheath in the Central Nervous System?

• Schwann Cells

• Astrocytes

• Oligodendrocytes

• Microglia

The area of the brain primarily responsible for the regulation of homeostasis is the:

• Cerebrum

• Cerebellum

• Hypothalamus

• Hippocampus

Which of the following is a function of the spinal cord?

• Producing cerebrospinal fluid

• Conducting sensory information to the brain

• Synthesizing neurotransmitters

• Regulating blood pressure

The process by which the brain interprets and organizes sensory information is known as:

• Homeostasis

• Myelination

• Perception

• Reflex action
