- What are the two main body cavities and what is contained in them?
- What is contained in the cranial cavity?
- Describe a disulfide bond?
- Point out cell organelles and name
- What is the cell membrane made up of and what is its function?
- b 1. The dorsal cavity which contains the spinal and cranial cavity
2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
- c 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
- d Contains skull and brain (CNS)
- e covalent bond formed between two atoms of sulfur
(ex: strand of hair maintains its shape)
5 Multiple choice questions
- 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)
- 1. Simple squamous -one layer of flat cells (alveoli of lungs, permits diffusion of gases)
2. Stratified squamous- many layers of cells (epidermis, lining of esophagus and vagina)
3. Transitional- many layers of cells (lining of bladder, permits expansion)
4. Cuboidal- one layer of cube shaped cells (thyroid gland, salivary gland, kidney tubules) excretory
5. Columnar- One layer of column shaped cells (lining of stomach, lining of small intestine and absorbs products in digestion)
6. Ciliated- one lay of columnar cells with cilia on free surfaces (lining of trachea to sweep mucus and dust pharynx and lining of fallopian tube to sweep ovum toward uterus)
- 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)
- Spinal vertebre
- 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 True/False questions
Describe an ionic bond? → Involves loss of electron of one atom and the gaining of an electron on another atom (ex: NaCl or salt)
What are the different kinds of bonding atoms? → - cell membrane
- cytoplasm and organelles
What are the cell organelles and what do they do? → 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.
What is homeostasis? → ability of the body to maintain a relatively stable metabolism and to function normally despite changes
What are the major parts of a cell? → - cell membrane
- cytoplasm and organelles
