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 |
