Question 1: tendons and ligaments are made mainly of the protein ______

Answer:

collagen

Question 2: Cartilage function

Answer:

Cartilage functions to support and protect.

Question 3: Mast Cells

Answer:

abundant along blood vessels, they secrete a chemical called heparin (an anticoagulant that inhibits blood clotting) and histamine (increases blood flow by vasoldilation).

Question 4: Adipocytes/ Fat Cells

Answer:

store triglycerides

Question 5: Fibers

Answer:

Protein fibers are embedded in the matrix between the cells of connective tissue. They are synthesized by fibroblasts & provide strength & support for tissues.

Question 6: what does adipose tissue look like in tissue section?

Answer:

cells are big, clear looking areas, nucleus is squished to the side.

Question 7: What makes up the matrix of connective tissue?

Answer:

Ground substance & fibers

Question 8: Hyaline Cartilage

Answer:

Most prevalent in the body, light blue in color. it consists of equal collagen to ground substance. Forms articular cartilage in joints, rings in the trachea, tip of nose. as well as most of the fetal skeleton (which slowly turns to bone after birth)

Question 9: What do epithelium typically rest on? (tissue type)

Answer:

nearly every epithelium rests on a layer of areolar tissue, whose blood vessels provide nourishment to epithelium

Question 10: hyalo-

Answer:

glassy (hyaline)

Question 11: Elastic Connective Tissue

Answer:

has branching, elastic fibers. Forms vocal cords & ligaments in spinal cord. Also found in walls of large & medium arteries (esp. the aorta). This allows the walls to expand & retract when a bolus of blood comes through from the heart.

Question 12: tendons are composed of ____

Answer:

dense regular connective tissue

Question 13: Dense Irregular Connective Tissue

Answer:

Collagen fibers run in random directions; this meshwork enables this tissue to withstand stresses that are applied in unpredictable directions. forms lower part of dermis, also forms protective capsules around certain organs (i.e. spleen & kidney)

Question 14: osteocytes & chondrocytes occupy little cavities called ______

Answer:

lacunae

Question 15: Fibrous Connective Tissue

Answer:

any connective tissue with a preponderance of conspicuous fiber, (such as areolar, reticular, dense regular & dense irregular connective tissue)

Question 16: proteoglycans in hyaline cartilage?

Answer:

Proteoglycan aggregates function as minute sponges, capable of trapping large quantities of water. this trapped water allows cartilage to spring back after being compressed.

Question 17: Fibrocartilage

Answer:

more collagen fibers present, running parallel. Very tough cartilage. Found in intervertebral discs (ring of fibrocartilage w a gel-like core), pubic syphysis, menisci in knee.

Question 18: Stroma

Answer:

sponge-like, supporting framework inside a soft organ (like spleen or lymph nodes).

Question 19: plas-

Answer:

formed (plasma)

Question 20: Reticular Tissue

Answer:

a mesh of reticular fibers & fibroblasts that form a structural, sponge-like framework (stroma) in the spleen & lymph nodes. These fibers are so small you must use silver stain to see them.

Question 21: How big are adipose cells

Answer:

they are big! 70-120 micrometers but can be 5 times bigger in obese people (RBC's only 7 micrometers)

Question 22: ecto-

Answer:

outer (ectoderm)

Question 23: Two types of Macrophages?

Answer:

wandering = leave the blood and migrate to infected tissues.fixed = remain in certain tissues of the body

Question 24: How is fibrocartilage distinguished on a tissue section?

Answer:

coarse, readily visible bundles of collagen. "a zillion fibers"

Question 25: Reticular Fibers function

Answer:

Similar to collagen fibers, they provide support & strength & also form the spongelike, supporting framework (known as the stroma) inside soft organs such as the spleen & lymph nodes. Also forms the basement membrane.
