Unit 2 Mock
| Question | Answer |
|---|---|
| What are the four types of tissue? | Epithelial, Connective, Muscle, Nervous |
| Epithelial tissue | covers and protects all body surfaces; skin |
| Connective tissue | Binds, protects and serves as framework; cartilage |
| Muscle tissue | contracts producing body movement; gluteus maximus |
| Nervous tissue | sends electrical impulses regulating body functions; brain |
| Melanin | Produced by melanocytes to give skin color, absorb UV light and is in the stratum basale layer |
| Types of melanin | Pheomelanin (red/yellow) and eumelanin (brown and black) |
| Bone structure | Is the internal framework of bones |
| The functions of the bones? | Support, Protect, Movement and anchorage, Mineral storage, and hematopoiesis |
| Short bones | Short and flexible; in tarsals and carpals |
| Long bones | long; In the femur |
| Flat bones | flat protection; scapula, ribs |
| Irregular bones | Are not short, long, or flat. Vertebrae |
| Membrane | 2 layers of tissues that usually produced a fluid to reduce friction. Only located in the connective and epithelial tissues |
| Cutaneous membrane | Covers the body |
| Synovial membrane | Lines the joints |
| Serous membrane | Lines closed body cavities |
| Mucous membrane | Lines organs leading outside the body, produces snot |
| Fibrous joint | Dense connective tissues that connect bones; skull |
| Cartilaginous joint | hyaline cartilage or fibrocartilage connects bones; vertebrae |
| Synovial joint | most complex, allows free movement; elbow |
| Synarthroses | Immovable; skull |
| Amphiarthroses | Slightly movable; vertebrae |
| Diarthroses | freely moveable; elbow |
| Pairs of ribs and where they attach | 7 true ribs; attach to the sternum 3 false ribs; attach to rib 7 2 floating false ribs; do not attach to the sternum but they are attached to the vertebrae |
| How do we name epithelial tissue? | by the number of layers and the shape of the outer most cell. |
| Squamous | Flat |
| Cuboidal | cube shaped |
| Columnar | column shaped |
| Simple | one layer |
| Stratified | 2 or more layers |
| Pseudostratified | Falsely layered (appears to have several but has only one |
| Define the process of DNA sequencing | Process of determining the precise order of nucleotide within a DNA molecule to code genetic information. |
| Why is DNA sequencing important? | DNA sequencing is important for cell reproduction and the replication, transcription , and translation that happens during cell reproduction |
| DNA Original strand, ATC-TAC-CAG | DNA Rep: TAG-ATG-GTC RNA: AUC-UAC-CAG |
| What is the purpose of Sebaceous glands and where are they located? | The purpose of the Sebaceous glands is to release sebum (oil) which helps to prevent water loss and lubricates the skin making it soft and pliable. these glands are in the dermis layer the skin. |
