122 Chapter Five Histology Can You Synthesize What You've Learned? 25. For each of the microscope slide? (Circle yes or no for each) a. cross section of the humerus (the arm bone) Yes b. cross section of the large intestine c. cross section of a pinky finger d. cross section of a small blood vessel e. cross section of a ureter (-0.5 cm in diameter) Yes ne) Yes No Yes No Yes No Yes No No s very flexible. Given what is known about the 26. A scientist is interested in developing a tissue that can resist stretch in multiple directions, yet also remains very flexible properties of human tissues, describe how the scientist might design such a tissue. Cartilage is unique as a connective tissue in that it is avascular. What limitations does avascularity impose on cartilage as a tissue? 28. Two of the surface modifications of epithelial cells, microvilli and cilia, are commonly confused with each other. In the space below, describe how you would teach a fellow student to distinguish between these two surface modifications 9. Most tumors arise in cells that are constantly undergoing cell division, or mitosis (for example, skin cells).A patient has recently been diagnosed with a brain tumor. What type of cell did the tumor most likely arise from-a neuron or a glial cell? A patient has recently been diagnosed with an osteosarcoma. In the space below, explain what cells this tumor most likely arose from and why.

Explanation / Answer

25) The standard microscopic slide has a length of 75 mm, width of 25 mm and a thickness of 1 mm.

a) diameter of humerus is 60 mm. It cannot fit its entirety on microscopic slide.

b) diameter of large intestine is 3 inches. So, it cannot be fit in single microscopic slide.

c) The cross section of pinky finger will be less than 20 mm. So, it can fit in microscopic slide.

d) The cross section if small blood vessel is around 5-10 mm. So, it can fit in microscopic slide.

e) The cross section of ureter is 5 mm. So, it can fit in microscopic slide.
