  • A. Meninges
  • B. Meningeal fluid
  • C. Cerebrospinal fluid
  • D. All of the above

Explanation: Cerebrospinal fluid surrounds the brain and spinal cord, absorbing shocks and reducing the effect of bumps and jolts.

Correct answer: Cerebrospinal fluid
  • A. Medulla
  • B. Pons
  • C. Cerebellum
  • D. All of these

Explanation: The hindbrain includes the medulla, pons, and cerebellum. Together, these structures regulate vital functions, relay information, and help…

Correct answer: All of these
  • A. Medulla
  • B. Pons
  • C. Hypothalamus
  • D. Cerebellum

Explanation: The medulla oblongata narrows downward and continues as the spinal cord, linking the brainstem with the spinal column.

Correct answer: Medulla
  • A. Sympathetic nervous system
  • B. Autonomic nervous system
  • C. Peripheral nervous system
  • D. Central nervous system

Explanation: The peripheral nervous system consists of nerves and ganglia outside the brain and spinal cord, including sensory and motor neurons.

Correct answer: Peripheral nervous system
  • A. Sensory
  • B. Motor
  • C. Mixed
  • D. All of these

Explanation: Cranial nerves can be sensory, motor, or mixed, depending on whether they carry sensory information, motor commands, or both.

Correct answer: All of these
  • A. Alcohol
  • B. Nicotine
  • C. dopamine
  • D. All of these

Explanation: Nicotine acts on postsynaptic nicotinic acetylcholine receptors in the nervous system, including receptors associated with both central…

Correct answer: Nicotine
  • A. Cerebral cortex
  • B. Corpus coliseum
  • C. Cerebral hemispheres
  • D. None of these

Explanation: The cerebral cortex is the outer layer of the cerebrum and is folded into ridges and grooves called convolutions.

Correct answer: Cerebral cortex
  • A. Alcohol
  • B. Nicotine
  • C. Dopamine
  • D. All of the above

Explanation: Nicotine activates the autonomic nervous system, commonly raising heart rate and blood pressure and stimulating gastrointestinal activity…

Correct answer: Nicotine
  • A. Cranium
  • B. vertebral column
  • C. Meninges
  • D. All of the above

Explanation: The skull, or cranium, protects the brain, while the vertebral column protects the spinal cord; both are also enclosed by the meninges.

Correct answer: All of the above
  • A. White matter
  • B. Gray matter
  • C. Cell bodies
  • D. Nerve fibers

Explanation: White matter consists mainly of bundles of myelinated axons, or tracts, which rapidly transmit signals through the nervous system.

Correct answer: White matter
  • A. Ganglia
  • B. Nerves
  • C. Spinal cord
  • D. All of these

Explanation: A ganglion is a cluster of neuronal cell bodies located in the peripheral nervous system.

Correct answer: Ganglia
  • A. Forebrain
  • B. Midbrain
  • C. Hind brain
  • D. Amygdala

Explanation: The midbrain contains the inferior colliculi, involved in auditory relay, and the superior colliculi, which help control visual reflexes…

Correct answer: Midbrain
  • A. Medulla
  • B. Pons
  • C. Cerebellum
  • D. All of these

Explanation: The pons contains neural systems involved in sleep and wakefulness and helps regulate the rate and pattern of breathing.

Correct answer: Pons
  • A. Alzheimer's disease
  • B. Drug abuse
  • C. Epilepsy
  • D. Parkinson's diseases

Explanation: Parkinson’s disease commonly begins in the 50s or 60s, and repeated or severe head trauma can increase risk.

Correct answer: Parkinson's diseases
  • A. Electrocardiogram
  • B. Electroencephalography
  • C. Alcohol tolerance test
  • D. Insulin

Explanation: Electroencephalography, or EEG, records the brain’s electrical activity and can reveal the abnormal discharges associated with epilepsy.

Correct answer: Electroencephalography
  • A. Brain
  • B. Nerves
  • C. Ganglia
  • D. Spinal cord

Explanation: Nerves are bundles of axons, and they may also contain associated dendritic fibers, enclosed in connective tissue outside the central…

Correct answer: Nerves
  • A. Sympathetic nervous system
  • B. Parasympathetic nervous system
  • C. Somatic nervous system
  • D. Peripheral nervous system

Explanation: The vagus nerve is the major cranial component of the parasympathetic system, which also includes fibers arising from the lower spinal…

Correct answer: Parasympathetic nervous system
  • A. Medulla
  • B. Pons
  • C. Cerebellum
  • D. Cerebrum

Explanation: The hindbrain includes the medulla, pons, and cerebellum, whereas the cerebrum is the largest part of the forebrain.

Correct answer: Cerebrum
  • A. Sympathetic
  • B. Parasympathetic
  • C. Somatic
  • D. Peripheral

Explanation: The sympathetic nervous system prepares the body for emergency action through the fight-or-flight response, increasing heart rate and…

Correct answer: Sympathetic
  • A. Medulla
  • B. Pons
  • C. Cerebellum
  • D. Amygdala

Explanation: The cerebellum is especially well developed in birds and contributes to coordinated movement, motor learning, and the retention of learned…

Correct answer: Cerebellum
