Psychology and the Nervous System

What are neurotransmitters?

• Hormones released by the endocrine system.

• Electrical signals transmitted between neurons.

• Chemical messengers between neurons.

• Proteins responsible for muscle contraction.

How does brain plasticity affect learning and memory?

• Brain plasticity only affects memory, not learning.

• Brain plasticity allows the brain to change and adapt, facilitating learning and memory.

• Brain plasticity has no effect on learning and memory.

• Brain plasticity hinders learning and memory.

What is the function of the central nervous system?

• The function of the central nervous system is to digest food.

• The function of the central nervous system is to regulate body temperature.

• The function of the central nervous system is to produce hormones.

• The function of the central nervous system is to process and coordinate information.

What are the two main divisions of the peripheral nervous system?

• sensory nervous system and motor nervous system

• central nervous system and autonomic nervous system

• sympathetic nervous system and parasympathetic nervous system

• somatic nervous system and autonomic nervous system

What is the role of sensory neurons in the nervous system?

• They transmit motor information from the central nervous system to the body.

• They transmit sensory information from the body to the central nervous system.

• They regulate the body's internal functions.

• They are responsible for cognitive processes in the brain.

Which neurotransmitter is associated with pleasure and reward?

• serotonin

• dopamine

• acetylcholine

• norepinephrine

How does brain plasticity contribute to recovery from brain injuries?

• Brain plasticity allows the brain to reorganize and form new connections after injury, enabling recovery.

• Brain plasticity can actually hinder recovery from brain injuries.

• Brain plasticity only occurs in children, not adults.

• Brain plasticity has no impact on recovery from brain injuries.

What are the major components of the central nervous system?

• stomach and intestines

• heart and lungs

• liver and kidneys

• brain and spinal cord

What are the functions of the autonomic nervous system?

• Controls involuntary bodily functions

• Regulates conscious bodily functions

• Coordinates voluntary movements

• Controls sensory perception

How do sensory neurons transmit information to the brain?

• Through magnetic signals

• Through mechanical signals

• Through electrical signals

• Through chemical signals
