|---|---|
 name the 6 branches of science | anatomy, physiology, histology, embryology, pathology, biology |
| anatomy | the study of the structure of the body and the relationship of the parts |
| physiology | the study of the normal functions and activities of organisms |
| histology | the study of the structure, composition, and function of normal cells and tissues |
| embryology | the study of the origin and development of an organism. From conception to birth. |
| pathology | the study the changes to normal structure and function of living things caused by disease |
| nucleus | spherical, centrally located "brain" of the cell. |
| nuclear membrane | encloses and protects the nucleus |
| cytoplasm | jelly-like substance containing fibers that support the cell |
| Golgi Apparatus | consists of small sacs, believed to manufacture carbohydrates and combine them with proteins |
| mitochondria | organelle with small sacs thought to provide the energy for the cell |
| lysosomes | sacs containing enzymes that digest molecules and particles for the cell. |
| endoplasmic reticulum | canals consisting of smooth and rough portions where the ribosomes containing RNA attach. |
| 4 types of tissue | epithelial, connective, muscle, nerve |
| 5 types of epithelial tissue | endothelium, mesothelium, simple, stratified, pseudostratified |
| endothelium | type of epithelial tissue that surrounds the heart, blood, and lymph vessels. |
| mesothelium | type of epithelial tissue that covers the surfaces of serous membranes. |
| simple epithelial tissue | type of epithelial tissue that has one layer of cells |
| stratified epithelial tissue | type of epithelial tissue that has three or more layers |
| pseudostratified epithelial tissue | type of epithelial tissue that has one layer but appears to have more. |
| 7 types of connective tissue | bone, cartilage, dense fibrous, loose arieolar, reticular, adipose, hematopoietic |
| bone | type of connective tissue that is hard, unbendable, supports the body |
| reticular | webike connective tissue that supports the nerves and capilaries |
| loose, arieolar | type of connective tissue that is elastic and stretchable, connects adjacent body structures |
| dense fibrous tissue | type of connective tissue that is strong and bendable, found in tendons and ligaments |
| adipose | type of connective tissue that is fatty, pads and protects |
| cartilage | type of connective tissue that is firm and bendable |
| hematopoietic | type of connective tssue that produces blood, found in the bone marrow and lymphatic system |
| 3 types of muscle tissue | skeletal, smooth, cardiac |
| skeletal muscle tissue | type of muscle tissue that is striated and voluntary |
| smooth muscle tissue | type of muscle tissue that is smooth and involuntary |
| cardiac muscle tissue | type of muscle tissue that is striated but involuntary |
| nervous tissue | composed of nerve cells, nerve fibers, and supporting tissue called neuralgia |
| 9 body systems | skeletal, cardiovascular, respiratory, integumentary, urogenital, gastrointestinal, nervous, muscular, endocrine |
| skeletal system | body system that is the framework of the body, supports organs, attachment place for muscles |
| muscular system | body system that permits motion and movement. |
| cardiovascular system | body system that transports blood, includes the lymphatic system |
| respiratory system | body system that absorbs oxygen and removed carbon dioxide |
| integumentary system | body system that incudes the skin, hair, nails, sweat, sebaceous glands. |
| urogenital system | body system that provides for reproduction and urine excretion |
| nervous system | body system that processes stimuli and enabes the body to act and respond |
| endocrine system | body system that manufactures hormones |
| gastrointestinal system | body system that digests and absorbs food and excretes waste. |
