| Anterior (ventral) | Describes the front or direction toward the front of the body. |
| Cerebrospinal fluid (CSF) | A colorless fluid produced by the brain that cushions the brain and spinal cord within the posterior (dorsal) cavity. |
| Coelomic | Cavities that do not open to the outside. |
| Connective tissue | Type of tissue that serves to hold in place, connect, and integrate the body’s organs and systems. |
| Cutaneous membrane | Epithelial tissue made up of stratified squamous epithelial cells that cover the outside of the body; skin. |
| Deep | Describes a position farther from the surface of the body. |
| Distal | A position in a limb that is farther from the point of attachment or the trunk of the body. |
| Epithelial membrane | Epithelium attached to a layer of connective tissue. |
| Frontal plane | Two-dimensional, vertical plane that divides the body or organ into anterior and posterior portions. |
| Homeostasis | The state of steady internal conditions maintained by living things. |
| Inferior (caudal) | A position below or lower than another part of the body proper. |
| Lateral | Describes the side or direction toward the side of the body. |
| Medial | Describes the middle or direction toward the middle of the body. |
| Mucous membrane | Epithelial membranes that line the body cavities and hollow passageways that open to the external environment. |
| Parietal layer | Outermost layer of the pleura that connects to the thoracic wall, mediastinum, and diaphragm. |
| Pericardium | Membrane that separates the heart from other mediastinal structures; consists of two distinct, fused sublayers: the fibrous pericardium and the parietal pericardium. |
| Peritoneum | Serous membrane that lines the abdominopelvic cavity and covers the organs found there. |

| Serous membrane | One of the thin membranes that cover the walls and organs in the thoracic and abdominopelvic cavities. |
| Serous space | The very thin, fluid-filled space between the parietal and visceral layers. |
| Superficial | Describes a position nearer to the surface of the body. |
| Superior (cranial) | A position above or higher than another part of the body proper. |
| Supine | A face-up orientation. |
| Synovial membrane | Thin layer that lines the inner surface of the joint cavity at a synovial joint; produces the synovial fluid. |
| Tissue membrane | Thin layer or sheet of cells that covers the outside of the body, organs, and internal cavities. |
| Visceral layer | Innermost layer of the pleura that is superficial to the lungs and extends into the lung fissures. |
