Vet Physiology & Anatomy (Cells)
| Question | Answer |
|---|---|
| Anatomy | Deals with the form and structure of the body and its parts - what things look like and where they are located |
| Physiology | Deals with the functions of the body and its parts - how things work and what they do |
| Microscopic anatomy | deals with structures so small we need a microscope to see |
| Macroscopic anatomy- (gross anatomy) | deals with body parts large enough to be seen with the unaided eye |
| Regional anatomy | to study anatomy by individual regions |
| Systemic anatomy | to study anatomy by systems of the body (ex. Nervous system |
| Sagittal- | runs the length of the body divides into left and right not necessarily equal |
| Median | runs the length of the body divides into left and right equally |
| Transverse | across the body that divides into cranial and caudal |
| Dorsal | through the body divides into dorsal and ventral |
| Homeostasis | is the maintenance of a dynamic (activity, energy, and work) equilibrium (balance)in the body. Ex. Road of life, the car is the animal’s body, and homeostasis is all the little inputs and corrections necessary to keep the “car” alive |
| What are the function of Acids and Bases? | Acids and Bases are both electrolytes because when added to water they transmit electricity |
| What is the cytoplasm? | Inner substance of the cell nucleus |
| What is mitochondria? hint: energy snackbar | power house, 95% of energy that fuels cell. High energy cells have more (cardiac cells) |
| Organelles | tiny organs |
| Ribosomes | protein synthesis, envelopes and moves throughout cell |
| Endoplasmic Reticulum (Smooth) | (no ribosomes) active in the synthesis and storage of lipids |
| Endoplasmic Reticulum (Rough) | (ribosomes attached) involved in production of protein |
| Golgi apparatus | receive proteins from ER and modify by adding sugar groups. Then package into vesicles and distribute. |
| Cytoskeleton | Outer layer of cell |
| Cytosol | Fluid of cell |
| Why do cells divide? | Growth, Repair, Cellular Replacement |
| Hypertonic | cells shrivel up, water hating |
| Hypotonic | Red cells puff up, water loving |
| Isotonic | red cells equal |
