Question 1

Taking a holistic approach is the idea that __________.

Accepted Answer

The concept that "the whole is always greater than the sum of its parts" is central to a holistic approach, emphasizing the importance of looking at systems or entities as complete wholes rather than merely assemblages of individual components.

Question 2

The biopsychosocial model was initially proposed by __________.

Accepted Answer

The biopsychosocial model, which emphasizes the importance of understanding human health and illness through a combination of biological, psychological, and social factors, was initially proposed by George Engel.

Question 3

The biopsychosocial model is a(n) __________ model of human behavior.

Accepted Answer

The biopsychosocial model is a holistic approach to understanding human behavior and health. It integrates biological, psychological, and social factors, rather than focusing on any single aspect of human function.

Question 4

The "instruction manual" for your body, consisting of your genes, is called your __________.

Accepted Answer

The answer of The "instruction manual" for your body, consisting...

Question 5

An architect builds a home from blueprints that contain the full plan for the layout of the house. In this case, the blueprints are like the __________ of the human, and the house is the __________.

Accepted Answer

The blueprints represent the genetic makeup or "genotype" which determines the characteristics of the house, similar to how a human's genotype determines their phenotype. The house itself is the "phenotype," the physical expression of the blueprint/genotype.

Question 6

When a caregiver provides good nutrition, cuddling, and protection, babies are more resilient to stress. This is a great example of __________.

Accepted Answer

This is an example of epigenetics, which refers to changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence. Good nutrition, cuddling, and protection can influence how genes are expressed, making babies more resilient to stress without altering their DNA.

Question 7

The process of natural selection involves the inheritance of genes, the desire of organisms to survive, and the selective survival of those with characteristics that make them more resistant to dangers in the environment. What else is a critical component of natural selection?

Accepted Answer

Variation in appearance and behaviors among individuals in a population is crucial for natural selection because it provides the raw material upon which natural selection can act. Without variation, there would be no differences in traits for natural selection to "select" for or against based on environmental pressures.

Question 8

Every neuron has five parts: __________.

Accepted Answer

Neurons, the basic units of the nervous system, consist of dendrites (which receive signals), a soma (cell body), an axon (which sends signals), axon terminals (end points of an axon where signals are transmitted to other cells), and a nucleus (which contains the cell's genetic material).

Question 9

Dendrites are covered in __________.

Accepted Answer

Dendrites are covered in receptors, which are specialized for receiving chemical signals from the axon terminals of other neurons during synaptic transmission.

Question 10

Mary steps on a sharp nail. Which neuron is responsible for sending a pain message up her spinal column, where it would then enter into the main area of the cord?

Accepted Answer

Sensory neurons are responsible for transmitting pain signals from the site of injury (in this case, the foot) to the spinal cord and brain, allowing the body to react to harmful stimuli.

Question 11

LaKeisha places her hand on a hot stove and then quickly removes it. Which of the following are responsible for sending a message to the muscles in LaKeisha's hand, resulting in her pulling it away from the hot stove?

Accepted Answer

Motor neurons are responsible for sending signals from the brain or spinal cord to the muscles, causing them to contract and pull the hand away from the hot stove.

Question 12

Which of the following cells mediate the conversation between sensory and motor neurons?

Accepted Answer

Interneurons mediate the conversation between sensory and motor neurons by receiving signals from sensory neurons and relaying them to motor neurons, facilitating the processing and response to sensory information.

Question 13

Three-year-old Candace watches Timmy fall and scrape his knee. She immediately comforts him and provides him with empathy. Candace is using her __________.

Accepted Answer

Candace is using her mirror neuron system, which is involved in empathy and understanding the emotions and actions of others by internally mirroring or simulating their emotional states or actions.

Question 14

During the process of an action potential, the cell moves positively charged ions inside the membrane. This is called __________.

Accepted Answer

Depolarization is the process during an action potential where the cell membrane's potential becomes less negative (more positive) due to the influx of positively charged ions into the cell.

Question 15

Often after playing a point, tennis players take a short break, drink water, wipe sweat off their hands, and prepare to play the next point. This process is very similar to the __________ in the neuron.

Accepted Answer

The refractory period in a neuron is a brief period after an action potential during which the neuron cannot fire another action potential, similar to the short break tennis players take to recover and prepare for the next point.

Question 16

The analogy of a key fitting into a lock is used to describe what process in the brain?

Accepted Answer

The answer of The analogy of a key fitting into...

Question 17

Jacqui was in a car accident and broke her leg. While they were trying to remove her from the car, she did not detect the pain of the broken leg. What neurotransmitter was most likely helping her keep her pain in control so she could get out of the car?

Accepted Answer

Endorphins are neurotransmitters that act as natural painkillers. During stressful or traumatic events, the body can release endorphins to help manage pain and promote a sense of well-being, which could explain why Jacqui did not detect the pain of her broken leg immediately.

Question 18

Glinnis is pedaling her bicycle through the park. She is relying on her __________ nervous system to help her pedal.

Accepted Answer

The somatic nervous system is responsible for voluntary movements, such as pedaling a bicycle, which involves controlling skeletal muscles.

Question 19

One night, Betty is walking home from the gym to her dorm. When she is approached by a strange man who clearly does not belong on campus, her pupils dilate and she gets goosebumps. What part of Betty's nervous system has been activated?

Accepted Answer

The answer of One night, Betty is walking home from...

Question 20

Following a stroke, Felipe struggled to form new memories. When he passed away, the doctor performing the autopsy noticed that much of Felipe's hippocampus was missing from his brain. The doctor concluded that the hippocampus is important in memory formation. This is an example of what technique for studying the brain?

Accepted Answer

The doctor's conclusion about the role of the hippocampus in memory formation based on observations from a single individual's brain after death is an example of a case study. This method involves in-depth investigations of a single subject or event to explore causation and find underlying principles.
