The epidermis is composed of a columnar epithelium. 5. After a cartilage cell becomes trapped in a lacunae, it is called a chrondrocyte.Explanation / Answer
1. Located retroperitoneally- Kidneys
2. Position of the shoulders relative to the sternum- Lateral
3. Permits the light to enter the specimen- Iris diaphragm.
4. Contains the brain and spinal cord- Dorsal cavity
5. The position of the nose relative to the mouth- Superior.
6. Mounting for objectives- Revolving nosepiece.
7. Sharpens the resolution of the specimen- Fine adjustment.
8. The breast is located in this region.- Pectoral
9. Objective is usually marked 10X- Ocular
10. Divides the body in equal left and right sides - Midsaggital.
11. Objective used to first focus on the specimen- Low power objective
12. Chromosome align at the equator- Metaphase
13. Epidermal region of keratohyalin and melanin granules- Stratum granulosum
14. Contains the navel- Umbilicus region
15. Central canal of concentric lamellae in compact bone- Haversian system
16. Epidermal layer of dead cells on the surface of the skin- Stratum corneum.
17. Secretes fluids not exposed to outside- Serous
18. Division of cytoplasm following nuclear division- Cytokinesis
19. Lines the respiratory tract- Pseudostratified
20. Ions with a positive charge- Cation
21. Pale, crescent shaped area at the base of a nail- Lunule
22. Spindle shaped or satellite cells that form connective tissue- Fibroblast
23. An epidermal layer found only in thick skin- Stratum lucidum
24. The simplest chemical units of matter - Atoms
25. The serous membrane lining the abdominal cavity- Peritoneum
True/Flase.
1. False- Jaundice occurs due to the misfunctioning of liver.
2. True.
3. False. Epidermis and dermis are both full of collagen
4.False
5. False- hyaline cartilage is chondrocytes trapped in lacunae.
