Genetics
The chance of developing a certain trait or condition increases due to our genetic code
What is genetic predisposition?
Individual nerve cells
What are neurons?
Neurons that take information from the senses to the brain
What are sensory neurons?
Neurons that take messages and send them to different parts of the brain
What are interneurons?
The system of glands that secrete hormones
What is the endocrine system?
Our genetic code
The environment we grow up in
What is nature?
What is nuture?
A neuron in its resting state
What is resting potential?
What is the central nervous system?
Consists of all nerves in body that aren't included in the central nervous system
What is the peripheral nervous system?
Controls most of human thought and behavior
What is the brain?
Material that makes up chromosomes.
What is DNA?
Neurotransmitter in charge of motor movement and alertness
Neurotransmitter in charge of mood control
Neurotransmitter in charge of pain control
What is dopamine?
What is serotonin?
What are endorphins?
Controls voluntary muscle movement
What is the somatic nervous system?
Controls the automatic functions of our body
Ex: heart and lungs

Carries messages to the stress response system
What is the parasympathetic nervous system?
Coordinates habitual muscle movements.
Involved in the control of our blood pressure, heart rate, and breathing.
Controls metabolic functions. Ex: hunger, thirst, and libido
Vital to our experiences and emotion.
What is the cerebellum?

What are chromosomal abnormalities?
The space between the terminal buttons of one neuron and the dendrites of the next neuron
What is synapse?
Neural pathways that control reflexes
What are reflex arcs?
Involuntary, automatic reactions to a stimulus
What are reflexes?
