Central Nervous System (Brain & Spinal Cord)

A stroke that damages Broca's Area in the brain typically results in what condition?

• Inability to understand spoken language, despite increased ability to speak.

• Difficulty producing intelligible words, despite some ability to understand speech.

• Complete loss of short term memory.

• Impaired motor skills and loss of sensation on the right side of the body.

How did James, who suffered from Broca's Aphasia, regain some ability to communicate?

• He learned to communicate through sign language.

• He used a text-to-speech device.

• He relearned to communicate by singing, which activated a different brain region.

• He took a prescription drug that improved his speaking ability but gave him a heart attack.

What does the statement that the brain has "super specific areas that have super specific functions" imply about its organization?

• The brain functions as a single, undifferentiated unit.

• Each region of the brain is responsible for a distinct, specialized function.

• Brain activity is primarily influenced by local environmental factors.

• The brain's functions are randomly distributed across its structure.

What are the primary functions of the Central Nervous System (CNS)?

• Collecting photosynthetic information from the body and transmitting it to chloroplasts within neurons.

• Integrating sensory information and coordinating both conscious and unconscious activity.

• Generating basic muscle reflexes without brain input.

• Producing hormones and regulating metabolism.

What is a key function of the spinal cord, independent of the brain?

• Processing complex thoughts and emotions.

• Conducting two-way neuronal signals between the heart and the lungs.

• Governing basic muscle reflexes and learned patterns like walking.

• Storing long-term memories.

Which of the following provides protection for the brain and spinal cord?

• Only the skull and vertebrae.

• Meninges, cerebrospinal fluid, and bones.

• Skin and muscle tissue.

• Blood-brain barrier only.

Which adult brain structures develop from the five secondary brain vesicles?

• Spinal cord, nerves, and ganglia.

• Brain stem, cerebellum, diencephalon, and cerebral hemispheres.

• Meninges, cerebrospinal fluid, and skull.

• Neurons, glial cells, and synapses.

Which part of the brain is responsible for regulating basic vital involuntary functions such as heart rate, breathing, sleep, and appetite?

• Cerebellum

• Brainstem

• Cerebral Cortex

• Thalamus

Which brain structure processes sensory information and sends out reflexive motor signals, such as tracking a fast-moving object or reacting to a sudden loud sound?

• Pons

• Medulla Oblongata

• Midbrain

• Cerebellum

The diencephalon includes several structures that regulate functions like homeostasis, alertness, and reproductive activity. Which of the following is NOT a part of the diencephalon?

• Thalamus

• Hypothalamus

• Epithalamus

• Cerebral Cortex
