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 |

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 |

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 |
