- A. occipital lobe
- B. parietal lobe
- C. temporal lobes
- D. reticular formation
Explanation: The occipital lobe contains the primary visual cortex, so damage there can cause partial blindness.
Correct answer: occipital lobe- A. activity
- B. sleep and arousal
- C. motor behavior
- D. higher reasoning
Explanation: The pons helps regulate sleep and arousal and also relays signals between brain regions.
Correct answer: sleep and arousal- A. the number of neurons in the brain
- B. electrical impulses from the brain
- C. chemical activity in the cranial nerves
- D. direct electrical stimulation and activation of the brain
Explanation: An EEG detects the brain's electrical activity through electrodes placed on the scalp.
Correct answer: electrical impulses from the brain- A. limbic system
- B. thalamus
- C. corpus callosum
- D. cerebellum
Explanation: The cerebellum is a small, folded structure attached to the rear of the brainstem.
Correct answer: cerebellum- A. synapse
- B. myelin sheath
- C. refractory period
- D. action potential
Explanation: An action potential is the brief electrochemical signal that travels along a neuron's axon.
Correct answer: action potential- A. Part of one's inherited structure
- B. Learned by experience
- C. Can be modified by environments
- D. All of the above
Explanation: Instinctive behavior is innate, meaning it is rooted in an organism's inherited biological structure rather than acquired through…
Correct answer: Part of one's inherited structure- A. Instinct
- B. Taxis
- C. Learning
- D. Kinesis
Explanation: Instinctive behaviour is especially valuable for animals that mature quickly and receive little or no parental teaching because it is…
Correct answer: Instinct- A. Kinesis
- B. Taxis
- C. Reflex
- D. Instinct
Explanation: Taxis is a directed movement toward or away from a stimulus, such as movement toward light or away from a harmful chemical.
Correct answer: Taxis- A. chemical; electrical
- B. acetylcholine, catecholamine
- C. dendrite; axon
- D. electrical; chemical
Explanation: The nerve impulse travelling within a neuron is primarily electrical, whereas communication across the synaptic gap is usually chemical…
Correct answer: electrical; chemical- A. uptake
- B. uploading
- C. regarding
- D. reuptake
Explanation: Reuptake is the process by which the presynaptic neuron takes neurotransmitters back from the synaptic cleft, helping terminate or…
Correct answer: reuptake- A. amounts of DNA and RNA
- B. types of neurotransmitters on either side of the nerve cell membrane
- C. types of neurons inside and outside the nerve cell membrane.
- D. concentrations of ions on either side of the nerve cell membrane
Explanation: The resting charge across a neuron’s membrane arises because ions such as sodium and potassium are unevenly concentrated inside and…
Correct answer: concentrations of ions on either side of the nerve cell membrane- A. soma; somatic membrane
- B. nucleus; nucleic dampers
- C. dendrite; dendritic arcs
- D. axon; axon terminals
Explanation: An axon carries impulses away from the cell body and usually branches into axon terminals, which form connections with other neurons.
Correct answer: axon; axon terminals- A. hypothalamus
- B. pituitary
- C. CNS
- D. midbrain
Explanation: The hypothalamus connects the nervous system with the endocrine system by regulating the pituitary gland, which then influences many other…
Correct answer: hypothalamus- A. Aphasia
- B. Broca's area
- C. Wernicke's area
- D. Agnosia
Explanation: Broca’s area supports speech production, including the grammatical organization and pronunciation of spoken language.
Correct answer: Broca's area- A. mimic the effects of neurotransmitters
- B. stimulate the production or hormones
- C. control heartbeat and breathing
- D. provide nutrients to interneurons
Explanation: Glial cells support neurons by supplying nutrients, maintaining their environment, and providing insulation and protection; interneurons…
Correct answer: provide nutrients to interneurons- A. muscles and glands
- B. skeletal joints
- C. axon terminals
- D. all vital organs
Explanation: Neurotransmitter receptors occur not only on neurons but also on muscles and glands, allowing neural signals to produce movement or…
Correct answer: muscles and glands- A. hypothalamus
- B. thalamus
- C. cerebellum
- D. cerebral cortex
Explanation: The cerebral cortex is far more developed and complex in humans than in a carp, supporting advanced perception, language, reasoning, and…
Correct answer: cerebral cortex- A. peripheral nervous system
- B. central nervous system
- C. afferent nervous system
- D. vascular nervous system
Explanation: The peripheral nervous system includes all neural structures outside the brain and spinal cord, including both the somatic and autonomic…
Correct answer: peripheral nervous system- A. prescription-only drugs
- B. synapses
- C. neurotransmitters
- D. beta blockers
Explanation: These substances can act as neurotransmitters, chemical messengers that transmit signals between neurons or from neurons to muscles and…
Correct answer: neurotransmitters- A. chemical; electrical
- B. electrical; mechanical
- C. electrical; chemical
- D. mechanical; electrical
Explanation: An action potential carries information electrically along a neuron, whereas communication across the synaptic gap usually uses chemical…
Correct answer: electrical; chemical
