| Cell | Basic unit of life |
| tissue | A group of similar cells that perform the same function. |
| Organs | Groups of tissues that work together to perform a specific function or related functions |
| organ system | group of organs that work together to perform a specific function |
| epithelial tissue | A body tissue that covers the surfaces of the body, inside and out |
| nervous tissue | A body tissue that carries electrical messages back and forth between the brain and every other part of the body. |
| muscle tissue | Tissue made of cells capable of contracting to produce movement |
| connective tissue | provides support for your body and connects all its parts |
| integumentary system | consists of skin, hair, and nails |
| Epidermis | outermost layer of skin |
| Dermis | middle layer of skin |
| hypodermis | the innermost layer of skin that insulates the body, acts as a protective padding, and stores energy |
| Muscular System | allows movement of the body and internal organs |
| voluntary muscle | muscle that can be consciously controlled |
| involuntary muscle | muscle that is not under conscious control |
| skeletal muscles | attached to the bones of the skeleton and make body motions possible |
| tendons | Connect muscle to bone |
| smooth muscles | involuntary muscles that work in internal organs |
| cardiac muscle | Involuntary muscle tissue found only in the heart |
| Cartilage | strong connective tissue that supports the body and is softer and more flexible than bone |
| bone | Dense, hard connective tissue composing the skeleton |
| Periosteum | A dense outer membrane covering the surface of bones |
| compact bone | dense, hard layers of bone tissue that lie underneath the periosteum |
| spongy bone | Layer of bone tissue having many small spaces and found just inside the layer of compact bone. |
| bone marrow | A soft tissue inside the bone that produces blood cells |
| joints | where two bones meet |
| ligaments | Connect bone to bone |
| pivot joint | rotating bone turns around an axis |
| gliding joint | allows one bone to slide over another |
| hinge joint | hinges at a central point and permits motion in only one plane |
| ball-and-socket joint | a joint where the rounded surface of a bone moves within a depression or on another bone so it can rotate in a circle |
| only in the heart | Where is cardiac muscle found? |
| volundary | What kind of muscle do you have control over? |
| phosphorus and calcium | minerals that make bones hard |
| attached to bones | Where is skeletal muscles found? |
| internal organs | Where is smooth muscle found? |
