| Question | Answer |
|---|---|
| Cell | Simplest form of life that can exist on its own |
| Cell membrane | Separates cytoplasm from the surrounding external environment |
| Cytoplasm | Gel-like fluid inside of cell that hold organelles in place & gives a cell its structure |
| Organelles | Little organs inside of cell |
| Nucleus | Control center of the cell |
| Ribosomes | Synthesize proteins |
| Endoplasmic Reticulum | Synthesizes proteins & lipids and has rough and smooth types |
| Golgi Body | Packing & shipping for cell - packs, stores &/or ships lipids & protein |
| Mitochondria | Power plant - site for cellular respiration that makes ATP (energy) |
| Lysosomes | Digestive enzymes for waste removal |
| Passive Processes | Process by which particles cross a cell membrane without the cell expending energy |
| Diffusion | Movement of molecules from an area of high concentration to an area of low concentration |
| Filtration | Pressure outside the cell pushing particles across the membrane |
| Osmosis | Moving a solvent from a low gradient to a high gradient |
| Active Processes | Process by which particles cross a cell membrane with the use of a cell’s energy |
| Pinocytosis | Cell drinking |
| Phagocytosis | Cell eating |
| Tissues | Made up of a group of like cells |
| Epithelial Tissue | Tissue that lines and covers |
| Muscle Tissue | Tissue that moves parts of the body |
| Smooth Muscle | Muscle tissue that moves organs |
| Cardiac Muscle | Muscle tissue that moves the heart |
| Skeletal Muscle | Muscle tissue that moves bones |
| Nervous Tissue | Tissue that sends electronic messages through a cell called a neuron |
| Connective Tissue | Miscellaneous category of tissue for tissue that connects throughout the body |
| Liquid Tissue | Lymph, blood, fluids the body makes |
| Osseous Tissue | Bone |
| Fibrocartilage | Dense cartilage found in less moveable areas like the vertebral column |
| Hyaline | Most abundant cartilage in the body and can be found at the ends of long bones |
| Elastic | Highly moveable cartilage that gives shape to parts like the ears and nose |
| Areolar | Most abundant loose tissue in the body also known as superficial fascia |
| Adipose | Fat loose tissue |
| Ligaments | Link bone to bone |
| Tendons | Tie muscle to bone |
| Retinacula | Bands that hold tendons in place in areas like ankles and wrists |
| Irregular | Tissue that makes deep fascia |
| Cutaneous | Membrane that makes skin |
| Mucous | Membrane that lines openings to outside of body and makes mucous |
| Serous | Membrane that lines closed body cavities and makes serous fluid |
| Parietal Membrane | Serous membrane that lines the cavity |
| Visceral Membrane | Serous membrane that lines organs |
| Synovial | Membrane that lines cavities of freely moving joints and makes synovial fluid |
