Unit 2: Biological Perspective Review

How does the biological perspective explain human behavior?

• Through cultural influences

• By examining genetic and physiological processes

• By focusing on environmental factors

• Through historical context

How does the endocrine system influence behavior?

• By releasing hormones that affect mood and energy

• By controlling voluntary muscle movements

• By processing sensory information

• By regulating body temperature

How does the nervous system differ from the endocrine system?

• The nervous system uses chemical signals, while the endocrine system uses electrical signals

• The nervous system uses electrical signals, while the endocrine system uses chemical signals

• Both systems use the same type of signals

• The nervous system is slower than the endocrine system

What are the different divisions of the nervous system?

• Central and peripheral

• Sympathetic and parasympathetic

• Autonomic and somatic

• All of the above

How do the three types of neurons differ?

• By their size

• By their function

• By their location in the body

• By their color

What is the role of the different parts of the neuron?

• To store energy

• To transmit and process information

• To produce hormones

• To protect the brain

What happens during each stage of neurotransmission?

• Neurons grow and divide

• Neurons change shape

• Chemical signals are sent, received, and recycled

• Electrical signals are blocked

What happens to the charge of the neuron during each of the stages of neurotransmission?

• It remains constant

• It becomes more positive, then returns to resting state

• It becomes more negative, then returns to resting state

• It fluctuates randomly

What do the 8 different neurotransmitters do?

• They all perform the same function

• They each have specific roles in mood, sleep, and cognition

• They only affect physical movement

• They are not involved in brain function

What methods do we use to study the brain?

• X-rays and ultrasounds

• MRI and PET scans

• Blood tests and biopsies

• Physical examinations
