Connective Tissue Extra Credit

ground substance and protein fibers

The ECM of connective tissue is composed of?

leukocytes and erythrocytes

What components of blood are visible in your image?

branching fibers and lots of extracellular matrix

What do you see in this reticular connective tissue?

chondrocytes

What is the term for the cells that make up cartilage?

fibrocartilage has many visible fibers, but hyaline does not.

What major difference do you note in your observation of hyaline cartilage (shown below) and fibrocartilage?

dermis of the skin (dense irregular connective tissue)

Where would you find this tissue?

Loose: areolar, reticular, and adipose Dense: dense regular, dense irregular, and elastic tissue Supporting: elastic cartilage, compact bone, hyaline cartilage, and fibrocartilage Fluid: blood

Which categories do these tissue fit into?

external ear and epiglottis

Which of the following are locations where elastic cartilage is found?

branching reticular fibers are visible in reticular connective tissue, but not areolar connective tissue

Which of the following best describes a difference between reticular and areolar connective tissues?

a group of large round cells with thin nuclei on the periphery of each cell

Which of the following best describes adipose connective tissue?

groups of concentric rings (lamellae) with darkly stained central canal within each osteon. cells (osteocytes) are flattened and separated within the rings.

Which of the following best describes compact bone (connective) tissue?

tightly packed, irregular shaped collagen fibers extending in multiple directions

Which of the following best describes dense irregular connective tissue?

tightly packed, parallel collagen fibers

Which of the following best describes dense regular connective tissue?

the many elastic fibers allow for stretching to recoil

Which of the following best describes why elastic connective tissue is found in the wall of the aorta, trachea, and vocal cords?

Lacuna; There are many of the dark oval structures present. The lacunae house osteocytes in living bone tissue.

Which of the following structures are most abundant in the field of view of compact bone at 400X total magnification?
