Unit 2 Anatomy

2. Comprised of fat cells, have large vacuoles, insulates body
4. Collagen fibers are arranged in one direction, provides tensile strength like a rope, found in tendons and ligaments
6. Lots of collagen, parallel running (cartilage)
8. Often two layers of cuboidal cells, rare, found in salivary and mammary glands
11. Contracts voluntarily, striated, controlled by somatic nervous system, connected to bones of skeleton (Muscle Tissue)
12. Osteoblasts create this, bone tissue
14. single layer of tall closely packed cells, secrete mucus for protection and absorption of substances, lining of digestive tract
15. Made by hematopoietic cells, makes blood
16. Contracts Involuntarily- non striated- found in walls of stomach, uterus, etc. (Muscle Tissue)
17. flat layer of cells that is thin and permeable, rapid diffusion of materials, blood vessels and lung tissues.
20. Provides flexible cushioning, found between vertebrae and in arteries
22. Collagen fibers are arranged in many directions, provides strength, found in capsules around organs
23. Columnar cells on the free surface, rare, larynx and male urethra.

1. Contains reticular fibers, which create a stiff framework that supports other cells
3. Thick layer provides protection for underlying layers, epidermal layer of skin
5. free surface cells vary on appearance, based on stretching of tissue. Urinary bladder
7. Glassy, firm ground substance with lacuna (cartilage)
9. Produces cartilage, produced by chondroblast
10. Produced by fibroblasts, connective tissue proper
13. Cell nuclei are found at different levels, so it appears stratified, though it is not. Secretion and absorption, upper respiratory tract
18. single layer of cube shaped cells, secretion and absorption of substances, found in kidney
19. Osteocytes secrete ground substances, fibers, collagen, and fluids, spongy or compact (tissue)
21. Contracts involuntarily, striated, found in heart, activate by brain or hormones (Muscle Tissue)
