Anatomy and Physiology
| Question | Answer |
|---|---|
| Tissues | group of cells with common embryonic origin with cimilr structure and function |
| 4 types of tissue | epithelial, connective, nervous, muscle |
| epithelial tissue classification | distinguishable by form based on function and location. (1st name # of layers. 2nd name shape) |
| Epitheleal facts | -avascular (no blood) but innervated (nerves) -apical-basal polarity |
| simple squamous function and location | transportation. capillaries |
| simple cuboidal function and location | secretion. testicles. |
| simple columnar function and location | secretion & absorption. digestive tract |
| pseudostratified columnar function and location | secretion and movement.Trachea |
| stratified squamous function and location | protection against abrasion. Vagina |
| Stratified cuboidal function and location | protection and secretion. Sweat glands |
| stratified columnar function | protect and secrete. |
| Transitional function and location | stretches. Bladder |
| Neurons | Thinking cells= action potential |
| glial cells/neuroglia | support |
| muscular tissue cells | -muscle fibers -myocyte |
| Skeletal muscle characteristics | -voluntary -striated -a lot of nuclei |
| cardiac muscle function and characteristics | -pumps blood -involuntary -striated |
| Smooth muscle function and characteristics | -involuntary -non-striated |
| skeletal muscle function and location | -movement -in bones |
| smooth muscle function and location | -motility (movement within body) -digestive tract |
