- What areas do connective tissue membranes cover?
- What are the cell organelles and what do they do?
- What is the formula for glucose?
- What is the cell membrane made up of and what is its function?
- What is a positive feedback mechanism?
- a meninges line the cranial and spinal cavities and cover the brain and spinal cord. They "line" and "cover".
- b ER or endoplasmic reticulum- are tubules that transport materials necessary for cell function within the cell.
Ribosomes- are very small structures made of protein and ribosomal RNA and are found on the surface of rough ER.
Proteasome- is a barrel shaped organelle made of enzymes that cut protein molecules apart.
Golgi apparatus- are flat, membranous sacs where carbohydrates are synthesized and are packed with other materials for cellular secretion.
Mitochondria- are oval organelles bound by a double membrane where cell respiration takes place and site of ATP production.
Lysosomes- are single membrane structures that contain digestive enzymes and eat dead cells and bacteria .
Centrioles- are a pair of rod shaped structures outside the nucleus that spindle fibers during cell division.
Cilia and Flagella- are thread-like projections through the cell membrane that can sweep materials across cell surface and flagellum provide mobility of the cell.
Microvilli- are folds of the cell membrane that increase surface area of membrane when needed. They are good for absorption of nutrients as well.
Cytoskeleton- are the framework and support of the cell. Made of microfiliaments.
- c C6H12O6
- d outer boundary of a cell made up of phospholipids, cholesterol and proteins.
its main job is to protect the cell and acts as a barrier for communication and assists in transport
- e the response to stimuli does not stop but rather keeps the sequence of events going. (requires an external brake)
EX: cervical stretching during childbirth
5 Multiple choice questions
- a watery solution (cytosol) of minerals, gases, organic molecules and cell organelles are found. it gives the cell its shape
- A buffer system is a chemical or pair of chemicals that minimizes changes in pH by reacting with strong acids or strong bases
(ex: buffer bonds to H+ ions when body fluid is becoming too acidic or release H+ ions when fluid becomes too alkaline)
- requires ATP to move molecules from an area of lesser to an area of greater concentration.
(Example: sodium pumps to move Na+ out of the cells)
- A genetic code for protein
- A solution with the same salt concentration as in cells
5 True/False questions
What are the two types of epithelial membranes? → Serous membranes: line some closed body cavities and cover the organs in those cavities (thoracic and abdominal cavities) CAVITIES THAT AREN'T OPEN TO AIR
Mucous Membranes: line the body tracts that have openings to the environment and have a mucous membrane to keep the lining of the cells wet (vagina, trachea, esophagus and stomach)
Review the types of cells by shape →
What is contained in the cranial cavity? → Contains skull and brain (CNS)
What is homeostasis? → Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
What are the two main body cavities and what is contained in them? → 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
