Free General Psychology MCQs with Answers

• A. Wundt
• B. Dewey
• C. Darwin
• D. Watson

Explanation: John B. Watson, the founder of behaviorism, emphasized environmental conditioning and argued that behavior could be shaped by experience.

• A. molecular configuration making up chromosomes
• B. germ-cell configurations in genes
• C. atom structure in genes
• D. neural structure in cell bodies

Explanation: DNA is the molecule that carries genetic information and forms the chemical material of chromosomes.

• A. reuptake site
• B. receptor site
• C. synapse
• D. axon terminal

Explanation: A synapse is the junction where one neuron communicates with another, usually by releasing neurotransmitters across a small gap.

• A. organize information
• B. carry information to central nervous system
• C. transmits messages between neurons
• D. transmit messages from motor to interneurons

Explanation: Sensory neurons carry information from receptors, such as those in the skin or eyes, toward the central nervous system.

• A. skeletal nervous system
• B. sympathetic nervous system
• C. limbic system
• D. parasympathetic nervous system

Explanation: The sympathetic nervous system arouses the body during stress or action, increasing heart rate and alertness.

• A. regeneration
• B. accommodation
• C. aphasia
• D. plasticity

Explanation: Brain plasticity is the capacity of neural tissue to reorganize and allow other areas to compensate for damage.

• A. messages
• B. reflexes
• C. both a and b
• D. none of these

Explanation: Neurons are specialized cells that receive and transmit messages through electrical impulses and chemical signals.

• A. axon
• B. autonomic
• C. linear circuit
• D. none of these

Explanation: The autonomic nervous system regulates involuntary functions such as breathing, digestion and heart activity.

• A. dendrite
• B. axon
• C. cell body
• D. synapses

Explanation: The axon is usually the neuron's longest projection, carrying impulses away from the cell body toward other neurons or effectors.

• A. limbic system
• B. skeletal nervous system
• C. central nervous system
• D. autonomic nervous system

Explanation: The autonomic nervous system carries involuntary motor messages to organs such as the heart, regulating heartbeat without conscious…

• A. release neurotransmitters
• B. receive incoming signals
• C. coordinate the activation of parasympathetic and sympathetic nervous system
• D. control pain

Explanation: Dendrites are branching extensions that receive incoming signals from sensory receptors or other neurons and carry them toward the cell…

• A. neurons
• B. nerves
• C. ganglia
• D. glia

Explanation: Neurons are the basic functional cells of the nervous system because they receive, process, and transmit nerve signals.

• A. peripheral
• B. autonomic
• C. central
• D. sympathetic

Explanation: The skeletal, more accurately called somatic, nervous system is a division of the peripheral nervous system and controls skeletal muscles.

• A. dendrite
• B. myelin sheath
• C. ganglion
• D. axon terminal

Explanation: The myelin sheath is a fatty insulating covering around some axons that speeds the transmission of nerve impulses.

• A. glucose absorption
• B. emotions
• C. metabolism
• D. sexuality

Explanation: Thyroid hormones regulate the body's metabolic rate, influencing how quickly cells use energy.

• A. polarization
• B. depolarization
• C. axonal transmission
• D. synaptic transmission

Explanation: Synaptic transmission is the process by which a neuron communicates with another neuron across the synaptic gap, usually by releasing…

• A. influencing the activity of the autonomic nervous system
• B. controlling the release of certain hormones
• C. influencing drivers such as hunger and thirst
• D. all of these

Explanation: The hypothalamus helps maintain homeostasis by influencing the autonomic nervous system, controlling several hormonal releases, and…

• A. interneurons
• B. sensory neurons
• C. motor neurons
• D. afferent neurons

Explanation: Motor neurons carry commands away from the central nervous system to muscles and glands.

• A. neurons
• B. neurotransmitters
• C. dendrites
• D. synapses

Explanation: Neurons are the specialized cells that receive, process and transmit information in the nervous system.

• A. nerves
• B. ganglia
• C. tracts
• D. dendrites

Explanation: Nerves are bundles of axons that extend from the brain and spinal cord through the peripheral nervous system.
