| Sagittal Plane | vertical plane that divides the human body into left and right sections |
| Anatomy and Physiology? | Anatomy is the study of body structure, whereas physiology deals with body function |
| Compound | Two or more elements are joined to form chemical combinations called compounds. |
| Element | An element is said to be “pure” in the sense that it cannot be broken down or decom-posed into two or more different substances. |
| Nitrogen | Component of all proteins and nucleic acids |
| Major elements of the body | oxygen (O), carbon (C), hydrogen (H), and nitrogen (N) |
| Gland cells | Release substances such as hormones, enzymes, mucus, and sweat |
| Immune cells | Recognize and destroy “non-self” cells such as cancer cells and invading bacteria |
| Cytoplasm | A Gel-Like substance that the inside of a cell is largely composed of |
| Muscle tissue | Produces movement; it moves the body and its parts. |
| Epithelial tissue | Outer layer of the skin, lining of the respiratory, digestive, urinary, reproductive tracts, and glands of the body. |
| Connective tissue | Supports the body and its parts, connect and hold them together, transport substances through the body, and protect it from foreign invaders. |
| Ectoderm | Epidermis of skin Tooth enamel Lens and cornea of eye Outer ear Nasal cavity Facial bones Skeletal muscles in head Brain and spinal cord Sensory neurons Adrenal medulla |
| Mesoderm | Dermis of skin Circulatory system Many glands Kidneys Gonads Muscle Bones (except facial) Adrenal cortex |
| Melanocytes | Contribute colored pigments to the skin and serve to decrease the amount of ultraviolet (UV) light that can penetrate into the deeper layers of the skin. |

| Stratum corneum | The most superficial layer of the epidermis. It is composed of very thin squamous (flat) cells, which at the surface are usually dead, and shedding. |
| Hematopoiesis | This is the blood cell formation, which is a vital process carried on by red bone marrow, or myeloid tis-sue. |
| Short bones | Wrist (carpal) and ankle (tarsal) bones |
| Sesamoid bones | Usually develop in the tendons close to the joints, The patella (kneecap) is the largest sesamoid bone |
| Axial skeleton | Made up of 80 bones, 74 upper body (skull, ribs, sternum, and vertebral column) and 6 tiny bones in the ear. |
