Concept explainers
Match the tissues in column A with the characteristics in column B. Place the letter of your choice in the space provided. (Some answers may be used more than once.)
To match:
The term from column A to the correct description in column B.
Introduction:
The connective tissue is a type of animal tissue. It has a mesoderm origin. The connective tissue plays an important role in insulation, protection, support and movement of substances. The major connective tissues are lymph, bone, cartilage, and blood.
Answer to Problem 2.1A
The table below represent the correct match from the Column A to Column B.
Column A | Column B |
a. Adipose | 2. Functions as a heat insulator beneath the skin. |
b. Areolar connective | 5. Binds the skin to underlying organs |
c. Blood | 3. Contains a large amount of fluid and transport wastes and gases |
d. Bone (compact) | 4. Cells in a solid matrix arranged around the central canal |
e. Dense irregular connective | 9. Main tissue of dermis |
f. Dense regular connective | 6. Main tissue of tendons and ligaments |
g. Elastic cartilage | 1.Forms framework of the outer ear |
h. Elastic connective | 10. Occurs in some ligament attachments between vertebrae and larger artery walls |
i. Fibrocartilage | 8. Pads between vertebrae that are shock absorbers |
j. Hyaline cartilage | 7. Forms flexible part of nasal septum and ends of long bones. |
k. Reticular cartilage | 11. Forms supporting tissue in walls of thymus and spleen |
Explanation of Solution
- The adipose tissue consists of fat-storing cells called adipocytes. These cells conserve energy as fat. The adipose tissue cushions and provide the heat (insulation) to the body. Hence, this can be correctly matched with 2.
- The areolar tissue is named because of its airy appearance. It connects skin to underlying tissues. Hence, it can be correctly matched with 5.
- Blood is a fluid connective tissue. It consists of plasma and transport gases and wastes. Hence, it can be correctly matched with 3.
- Bone is a kind of dense connective tissue. The solid matrix is responsible for the rigidity of bone. The cells present in solid matrix arranged themselves around the central canal. Hence, it can be correctly matched with 4.
- The dense irregular connective tissue is the main tissue of the dermis. The underlying layer of the epidermis is called dermis. Hence, it can be correctly matched with 9.
- The dense regular connective tissue consists of parallelly arranged collagen fibers. It consists of type I collagen fiber. This tissue is mainly present in tendons and ligaments and provides high tensile strength. Hence, it can be correctly matched with 6.
- The elastic cartilage is highly flexible connective tissue. It is present in the pinnae (outer ear). Hence, it can be correctly matched with 1.
- The elastic connective tissue is a modification of dense connective tissue. It is made up of elastic fibers. The ligament attachment between the artery wall and vertebrae consists of elastic connective tissue. Hence, it can be correctly matched with 10.
- The fibrocartilage is the strongest tissue that is present in the intervertebral. The fibrocartilage works as a shock absorber. Hence, it can be correctly matched with 8.
- Hyaline cartilage is present at joint surfaces. It is commonly present in the nose, trachea, ends of long bones and ribs. Hence, it can be correctly matched with 7.
- Reticular tissue consists of reticular fibers. It acts as a supporting tissue around the lymph nodes, spleen and kidneys. Hence, it can be correctly matched with 11.

- If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the intervalarrow_forwardWhat percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent.
