VERIFIED QUESTIONS AND CORRECT
ANSWERS GRADED A+
Histology is __________.
the study of normal structure of tissues
the study of the normal function of cells
the study of the normal function of tissues
the study of the normal structure of cells - ANS-the study of normal structure of tissues
The study of normal tissue structure is called __________.
cytology
biopsy
histology
autopsy - ANS-histology
Which of the following is NOT a tissue type?
,muscle tissue
epithelial tissue
connective tissue
extracellular matrix - ANS-extracellular matrix
Which of these tissue types has the most abundant ECM?
nervous tissue
muscle tissue
epithelial tissue
connective tissue - ANS-connective tissue
As you examine a slide under the microscope, you see multiple cell types surrounded by abundant ECM
and protein fibers. You identify this tissue type as __________.
epithelial tissue
nervous tissue
muscle tissue
connective tissue - ANS-connective tissue
Dr. Riehm shows you an unlabeled tissue slide and says the tissue is very resistant to stretching, tearing,
and compression. He then asks you what you can conclude about the structure of the extracellular
matrix (ECM)
The ECM has many elastic fibers and a fluid ground substance.
The ECM contains only collagen fibers but no ground substance.
The ECM contains collagen fibers embedded in a fluid ground substance.
The ECM has abundant collagen fibers in a gel-like ground substance. - ANS-The ECM has abundant
collagen fibers in a gel-like ground substance.
, Dr. Riehm continued to ask questions about epithelial tissues. He used the eyepiece pointer of the
microscope to mark a structure in an area of normal skin, and you are able to identify the structure as a
sweat gland. Since sweat is secreted onto the skin, you know that sweat glands are __________ glands
and their products have effects on __________ cells.
Endocrine; distant.
Endocrine; local.
Exocrine; local.
Exocrine; distant. - ANS-exocrine, local
Dr. Riehm has asked you to develop some flashcards pertaining to the different cells found in connective
tissue proper. Which one of the following is not a normal resident cell found in connective tissue
proper?
Chondrocytes.
Fibroblasts.
Adipocytes.
Mast cells. - ANS-chondrocytes
While making your flashcards, you see that skeletal muscle cells are multinucleated. Why do skeletal
muscle cells have this property?
Skeletal muscle fibers are formed by the fusion of embryonic chondroblasts.
Multinucleation is an advantage because of skeletal muscle fiber size and the amount of protein
synthesis that takes place in these metabolically active cells.
The original nucleus in a skeletal muscle fiber undergoes repeated rounds of mitosis.
Skeletal muscle fibers are formed by the fusion of osteogenic cells and the nucleus of each osteogenic
cell is retained in the mature muscle fiber. - ANS-Multinucleation is an advantage because of skeletal
muscle fiber size and the amount of protein synthesis that takes place in these metabolically active cells.
