Epigenetics involves changes in DNA sequence, while brain plasticity refers to the brain's ability to reorganize its structure and function.

Epigenetics refers to changes in gene expression without altering the DNA sequence, while brain plasticity is the brain's ability to reorganize its structure and function.

Epigenetics is the study of brain functions, while brain plasticity is about genetic mutations.

Epigenetics and brain plasticity are the same concepts, both referring to changes in the brain's structure.

the absorption by a presynaptic nerve ending of a neurotransmitter that it has secreted.

the process of breaking down neurotransmitters in the synaptic cleft

the release of neurotransmitters into the synaptic cleft

the binding of neurotransmitters to receptors on the postsynaptic neuron

a neural pathway responsible for reflex actions, which are involuntary and automatic responses to stimuli

a type of muscle contraction that occurs in response to voluntary movement

a brain structure that processes sensory information before it reaches consciousness

a sequence of events that leads to the formation of memories

Nature refers to the biological and genetic factors we inherit from our parents, while nurture encompasses the experiences and influences we encounter throughout our lives.

Nature is solely responsible for our personality, while nurture has no impact.

Nurture is about our genetic makeup, while nature is about our upbringing and environment.

Nature and nurture are two terms that mean the same thing.

a process where a cell's membrane potential becomes more negative

a process where a cell's membrane potential becomes more positive

a process that increases the rate of action potentials

a process that decreases the permeability of the cell membrane

sympathetic and parasympathetic divisions

central and peripheral divisions

somatic and autonomic divisions

afferent and efferent divisions

a type of carbohydrate that provides energy to cells.

a lipid that serves as a structural component of cell membranes.

a nucleic acid involved in protein synthesis.

A crucial hormone and neurotransmitter involved in the body's 'fight-or-flight' response

A type of vitamin essential for energy production

A common pain reliever used in headaches

A hormone that regulates blood sugar levels

A neurotransmitter and hormone that plays a crucial role in the body's stress response, regulating arousal, attention, and sleep.

A type of white blood cell involved in immune response.

A hormone that primarily regulates blood sugar levels.

A neurotransmitter that inhibits pain signals in the brain.

A neurotransmitter and hormone that plays a crucial role in the brain's reward system, influencing motivation, pleasure, and movement.

A type of protein that helps in muscle contraction.

A vitamin that is essential for bone health.

A mineral that aids in oxygen transport in the blood.

the process where a neuron's membrane potential returns to its resting state after it has become more positive

the process of a neuron's membrane potential becoming more positive than its resting state

the process of a neuron's membrane potential becoming negative after an action potential

the process of a neuron's membrane potential remaining constant during stimulation

The CNS includes the brain and spinal cord, while the PNS is responsible for communication between the CNS and the rest of the body.

The CNS is responsible for voluntary movements, while the PNS controls involuntary actions.

The CNS processes sensory information, while the PNS only transmits motor signals.

The CNS is the body's main processing center, while the PNS acts as a communication network.

A neurotransmitter that inhibits nerve transmission in the brain

A type of hormone produced by the pancreas

A protein that helps in muscle contraction

economic status, political environment, and technological advancement

A type of hormone that regulates metabolism

A neurotransmitter, a chemical messenger in the brain and nervous system that transmits signals between nerve cells and other cells

A protein that helps in muscle contraction

A vitamin essential for immune function

sensory neurons, interneurons, and motor neurons

sensory neurons, glial cells, and motor neurons

interneurons, sensory receptors, and motor neurons

sensory neurons, interneurons, and sensory neurons

refers to the idea that a nerve or muscle cell's response to a stimulus is either a full, complete response or no response at all, regardless of the stimulus's strength.

is the concept that all stimuli produce a proportional response in nerve or muscle cells.

indicates that nerve and muscle cells can only respond to strong stimuli, ignoring weaker ones.

suggests that muscle cells can only contract partially, depending on the strength of the stimulus.

a delay in responding to a second stimulus when it is presented shortly after a first stimulus

a period of time when a neuron is unable to fire again

the time taken for a muscle to relax after contraction

The ability of a material to allow fluids to pass through it.

The degree to which boundaries between different psychological roles, domains, or even social groups, are considered permeable or fluid.

The measure of how easily a substance can be compressed.

The extent to which an object can be divided into smaller parts.
