| Abdominal | anterior body trunk inferior to ribs |
| Acromial | Pertaining to the point of the shoulder |
| Anatomical position | erect, feet forward, arms at side with palms facing forward, head facing forward |
| Anatomy | study of body structure |
| Antecubital | front of elbow |
| Axillary | the armpit region |
| Brachial | region of the upper arm |
| Buccal | of or relating to the mouth. |
| Cardiovascular system | the body system that consists of the heart, blood vessels, and blood, and that carries needed substances to cells and carries waste products away from cells |
| Carpal | Pertaining to the wrist |
| Cephalic | Pertaining to the head |
| Cervical | neck region |
| Coxal | the hip region |
| Crural | region of the shin |
| Deltoid | a large triangular muscle covering the shoulder joint and serving to abduct and flex and extend and rotate the arm |
| Diaphragm | Large, flat muscle at the bottom of the chest cavity that helps with breathing |

| Digital | fingers and toes |
| Dorsal | Pertaining to the back |
| Endocrine system | the system of glands that produce endocrine secretions that help to control bodily metabolic activity |
| Excretion | getting rid of waste matter (as urine or sweat but especially feces) discharged from the body |
| Femoral | of or relating to or near the femur or thigh |
| Fibular | lateral side of the leg |
| Gluteal | pertaining to the buttocks or rump |
| Homeostasis | process by which organisms maintain a relatively stable internal environment |
| Inguinal | area where thigh meets body trunk; groin |
| Integumentary system | the skin and its accessory structures such as hair and nails |
| Lumbar | area of back between ribs and hips |
| Lymphatic system | a network of structures which drains fluid from tissue spaces and returns it to the blood |
| Metabolism | The combination of chemical reactions through which an organism builds up or breaks down materials |
| Midsagittal/median | divides the body into equal left and right halves |
| Muscular system | enables movement of the body and internal organs |
| Negative feedback | a mechanism of response in which a stimulus initiates reactions that reduce the stimulus |
| Nervous system | the sensory and control apparatus consisting of a network of nerve cells |
| Nutrients | compounds in food that the body requires for proper growth, maintenance, and functioning |
| Occipital | posterior surface of head |
| Orbital | eye region |

| Patellar | region of the kneecap |
| Pelvic | Pertaining to the pelvis region |
| Physiology | processes and functions of an organism |
| Popliteal | Posterior knee area |
| Positive feedback | A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change |

| Reproductive system | system of organs involved in producing offspring |
| Respiratory system | system responsible for taking in oxygen and releasing carbon dioxide using the lungs |
| Responsiveness | is the organism's ability to sense changes taking place inside or outside the body |
| Sacral | The posterior region between the hipbones |
