Question 1

Accepted Answer

SSRIs are commonly prescribed for depression.

Question 2

Human eggs and sperm each contain 23 ________, which are composed of long strands of ________.

Accepted Answer

Human eggs and sperm are haploid cells, each containing 23 chromosomes. These chromosomes are made up of long strands of DNA.

Question 3

The ________ of a neuron contain ________ that house neurotransmitters, the chemical messengers of the nervous system.

Accepted Answer

The terminal buttons of a neuron contain synaptic vesicles, which are small sacs that house neurotransmitters, the chemical messengers that neurons use to communicate with each other.

Question 4

A(n) ________ is the electrical signal that typically moves from the neuron's cell body down the axon to the axon terminals.

Accepted Answer

An action potential is the electrical signal that travels along the axon of a neuron, from the cell body to the axon terminals, facilitating neuronal communication.

Question 5

The ________ nervous system is responsible for stimulating digestion and causing the bladder to contract.

Accepted Answer

The parasympathetic nervous system is part of the autonomic nervous system responsible for rest and digest functions, including stimulating digestion and causing the bladder to contract.

Question 6

A particular electrical signal being transmitted to a neuron is sufficient to generate an action potential. If the magnitude of the incoming electrical signal is doubled, the action potential will ________.

Accepted Answer

Action potentials are all-or-nothing events; their strength, speed, or duration does not change with the magnitude of the incoming signal once the threshold is reached.

Question 7

Hyperpolarization means that the ________.

Accepted Answer

Hyperpolarization occurs when the membrane potential becomes more negative than the resting potential, often due to the efflux of potassium ions or the influx of chloride ions.

Question 8

The ________ is the difference in charge between the intracellular and extracellular space of a neuron.

Accepted Answer

The membrane potential is the difference in electric charge between the inside and outside of a neuron's cell membrane, which is crucial for the transmission of nerve impulses.

Question 9

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

Accepted Answer

Scavenger vesicles specifically for collecting excess neurotransmitters left over from neurotransmitter release do not exist as a recognized mechanism for dealing with excess neurotransmitters in the synaptic cleft. The primary processes for handling excess neurotransmitters include breakdown into inactive fragments, drifting away from the synapse, and reuptake by neurons or glial cells.

Question 10

In a resting state, sodium (Na⁺) is at a higher concentration outside the cell and potassium (K⁺) is more concentrated inside the cell. During an action potential, the sodium levels ________ inside the cell.

Accepted Answer

During an action potential, sodium channels open, allowing Na+ ions to flow into the cell, thereby increasing the sodium concentration inside the cell.

Question 11

Changes in behavior and cognitive processes over time are studied by ________.

Accepted Answer

Evolutionary psychologists study changes in behavior and cognitive processes over time, focusing on how evolutionary principles such as natural selection influence human behavior and mental processes.

Question 12

________ is a neurotransmitter with roles in pleasure and pain modulation.

Accepted Answer

Beta-endorphin is a neurotransmitter involved in pain relief and can also induce feelings of pleasure, fitting the description provided.

Question 13

________ asserts that our genes set the boundaries within which we can operate, and our environment interacts with our genes to determine where within those boundaries we will fall.

Accepted Answer

The concept of "range of reaction" asserts that our genetic makeup establishes the limits of our potential development and that our environment then interacts with these genetic potentials to determine where within those limits we actually fall. This concept emphasizes the interplay between genetics and environment in shaping our abilities, characteristics, and behaviors.

Question 14

The myelin sheath is made from ________.

Accepted Answer

The myelin sheath is made from glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. These cells wrap around axons to provide insulation and facilitate the rapid transmission of electrical signals.

Question 15

The space between two neurons is called the ________.

Accepted Answer

The space between two neurons is called the synapse. It is where the transmission of signals between neurons occurs.

Question 16

Which two neurotransmitters have roles in appetite suppression?

Accepted Answer

Dopamine and norepinephrine are involved in regulating appetite, with roles in promoting feelings of satiety and suppressing hunger.

Question 17

The theory of ________ states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.

Accepted Answer

The theory of evolution by natural selection, proposed by Charles Darwin, explains how organisms that are better adapted to their environment tend to survive and reproduce, while those less adapted are more likely to die off.

Question 18

Wendy's mother has blue eyes and her father has brown eyes. The allele for brown eye color is dominant (B) to the allele for blue eye color (b), but Wendy has blue eyes. Therefore, Wendy's ________ must be ________ and her father's must be Bb.

Accepted Answer

Wendy's genotype must be bb because she has blue eyes, which is a recessive trait. This means both of her parents must have contributed a b allele. Her father must be heterozygous (Bb) to have brown eyes but still carry the allele for blue eyes.

Question 19

The two major divisions of the nervous system are the ________ and ________.

Accepted Answer

The nervous system is broadly divided into two major divisions: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which comprises all the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

Question 20

The ________ nervous system is responsible for responses such as pupil dilation, increased heart rate, and increased respiration.

Accepted Answer

The sympathetic nervous system is part of the autonomic nervous system and is responsible for the body's 'fight or flight' responses, including pupil dilation, increased heart rate, and increased respiration.
