|---|---|
| Scientific Study of Life | Biology |
| The study of the structure of an organism and the relationship of its parts | Anatomy |
| tiny spheres of matter so small they are invisable | Atoms |
| The "powerhouses" of cells that provide energy needed by a cell for function, growth and repair | Mitochondria |
| the smallest and most numerous structural units that possess and exhibit the basic characteristics of living matter | Cells |
| "Towards the midline of the body" | Medial |
| Crosswise plane that divides the body or any of its parts into upper and lower parts | Transverse Plane |
| Part of the body that consist of the head, neck, torso and trunk | Axial |
| two or more elements are joined to form chemical combinations | Compounds |
| The number of protons in an atom’s nucleus | Atomic number |
| A chemical bond formed by the sharing of one or more pairs of electrons between the outer energy levels of two atoms | Covalent Bond |
| Large organic molecules important in living organisms | Biomolecules |
| inside of the cell is composed largely of a gel-like substance | Cytoplasm |
| This process of “self eating” | Autophagy |
| one of the largest cell structures , usually occupies the central portion of the cell. | Nucleus |
| The smallest cell fibers | Microfilaments |
| The cell’s internal “feet” are actually little protein structures | Molecular motors |
| functions to support the body and its parts, connect and hold them together, transport substances through the body, and protect it from foreign invaders. | Connective Tissue |
| mem-branes are smooth and slick and secrete a thick and colorless lubricating fluid | Synovial Fluid |
| a rather unique form of very hard connective tissue | Bone |
| basic organizational or structural unit of compact bone is the microscopic | Osteon |
| the superficial, thinner layer of skin | Epidermis |
| The process by which cells in this layer are formed from cells in deeper layers of the epidermis and then filled with keratin and moved to the surface is | Keratinization |
| sometimes called the subcutaneous layer, or superficial fascia ( | hypodermis |
| By about the sixth month of pregnancy the developing fetus is all but covered by an extremely fine and soft hair coat, | lanugo |
| The visible part of a hair is called | Shaft |
| fibrous bands that help hold the various bones together into an organized skeleton | Ligaments |
| medullary cavity is filled with connective tissue rich in fat—a substance | yellow marrow |
| mature, nondividing osteoblasts that have become surrounded by matrix and now lie within lacunae | osteocytes |
| bones of the skeletal system serve as a storehouse for about ______of the body's calcium reserve | 98% |
| forms the forehead and the anterior part of the calvaria or top of the cranium | Frontal Bone |
| Twelve pairs of ribs, together with the vertebral column and sternum, form most of the bony cage known as | Thorax |
| The largest sesamoid bone in the body | Patella |
| larger and stronger and more medially and superficially located of the two leg bones. | Tibia |
