  • A. The central nervous system includes the nerves through which the central nervous system interacts with the rest of the body
  • B. The peripheral nervous system includes the brain and the spinal cord
  • C. Afferent or sensory nerves carry information to the central nervous system from sensory neurons and regulate glandular secretion
  • D. Efferent or motor nerves extend out from the central nervous system to the organs

Explanation: Efferent, or motor, nerves carry commands away from the central nervous system to muscles and glands.

Correct answer: Efferent or motor nerves extend out from the central nervous system to the organs
  • A. Cell body, dendrites, axon
  • B. Cell body, nerves, axon
  • C. White matter, cell body, nerves
  • D. Internal body, external body, nerve branches

Explanation: A typical neuron has a cell body, dendrites, and an axon. Dendrites receive signals, the cell body maintains the neuron, and the axon…

Correct answer: Cell body, dendrites, axon
  • A. Dendrite
  • B. Neuron
  • C. Brain
  • D. Spinal Cord

Explanation: The neuron is the basic structural and functional unit of the nervous system because it receives, processes, and transmits information.

Correct answer: Neuron
  • A. Cell bodies
  • B. Non-myelinated nerve fibers
  • C. White matter
  • D. both a & b

Explanation: Spinal-cord gray matter contains neuronal cell bodies and many unmyelinated fibers, whereas white matter is mainly composed of myelinated…

Correct answer: both a & b
  • A. Forebrain
  • B. Midbrain
  • C. Hindbrain
  • D. All of these

Explanation: The forebrain includes the cerebrum, limbic system, and thalamus, making it the largest and most complex major brain division.

Correct answer: Forebrain
  • A. Thalamus
  • B. Cerebrum
  • C. Limbic system
  • D. All of the aboveTry Nootropic Supplements

Explanation: The thalamus acts as a major relay station, directing most incoming sensory information to appropriate areas of the cerebral cortex.

Correct answer: Thalamus
  • 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.
