| Central Nervous System | receiving, processing, and responding to sensory information. |
| Peripheral Nervous System | sending information from different areas of your body back to your brain, as well as carrying out commands from your brain to various parts of your body. |
| Medulla | located at the base of the brain stem, it controls basic life-support functions like heartbeat and breathing. |
| Pons | allows for the right and left hemispheres of the brain to exchange information about the senses, including sensory input and function. |
| Cerebellum | attached to the rear of the brainstem. It helps coordinate voluntary movements and balance. |
| Thalamus | the brain’s sensory switchboard, located on top of the brainstem. It directs messages to the sensory receiving areas in the cortex. |
| Hypothalamus | neural structure lying below the thalamus. It helps regulate many of the body’s maintenance activities, such as eating, drinking, and body temperature, and is linked to emotion. It maintains homeostasis. |
| Corpus Callosum | large band of neural tissue that connects the two brain hemispheres and allows them to communicate with each other |
| Frontal | located at the front of the brain, associated with; reasoning, planning and judgment |
| Parietal | located in the middle upper section of the brain, associated with; pressure, touch, and pain |
| Temporal | located on the bottom sides of the brain, associated with; sound interpretation and the language we hear |
| Occipital | located at the back lower portion of the brain, associated with; interpreting visual stimuli and information. |
| Association Areas | integrate information from different receptors or sensory areas and relate the information to past experiences. |
| Hormones | chemical messengers released from endocrine glands that travel through the blood system to influence the nervous system to regulate behaviors such as aggression, mating, and parenting of individuals |

| Chromosomes | carries the genetic, or hereditary, traits of an individual |
| Perception | The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events |
| Sensation | The process by which our sensory receptors and nervous system receive stimulus (information) from the environment |
| Absolute Threshold | The minimum amount of stimulation needed to detect a particular stimuli |
| Sensory Adaptation | the way our senses adjust to different stimuli |
| Retina | to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition. |
| Rods | Light/Dark |
