| Question | Answer |
|---|---|
| What are the levels of organization in the human body (smallest to largest)? | 1. Atom 2. Molecule 3. cell 4. tissue 5. organs 6. organ system 7.organism |
| How do cells work together to form tissues, organs, and organ systems? | through a building-block system of increasing complexity, moving from individual microscopic units to full living bodies |
| What are the four major types of tissues? | Epithelial tissue, connective tissue, muscle tissue, and nervous tissue |
| What is the primary function of the epithelial tissue? | Covers and protects body surfaces and lines organs and body cavities |
| What is the primary function of the connective tissue? | Supports. connects, protects, and binds other tissues together |
| What is the primary function of the muscle tissue? | produces movement by contracting |
| What is the primary function of the nervous tissue? | receives and transmits electrical signals to communicate and control body functions |
| Where can the epithelial tissue be found? | lining internal cavities, hollow organs, and blood vessels |
| Where can the connective tissue be found? | Bones and Skeleton |
| Where can the muscle tissue be found? | attached to bones, inside the walls of hollow organs, and within the heart |
| Where can the nervous tissue be found? | the brain |
| What does a histologist do? | prepares and stains tiny slices of body tissue so doctors can see them under a microscope and diagnose diseases like cancer |
| What is an example of a task a histologist might do? | cuts thin slices of tissues samples and mounts them onto a glass slide for analysis |
| how does examining tissues under a microscope help doctors identify diseases and abnormalities | shows cellular structures and abnormalities that are invisible to the naked eye |
| when someone has Bell palsy what tissue is affected and why does Bell palsy cause problems with facial movement? | Bell's palsy affects the facial nerve and the surrounding nerve tissues. Bell's palsy causes problems with facial movement because this specific nerve acts as the "electrical cord" that carries signals from your brain to the muscles in your face |
