4. Which type of epithelial tissue forms the inner lining of blood vessels?

a) Columnar epithelium
b) Cuboidal epithelium
c) Squamous epithelium
d) Ciliated epithelium

Answer:

c) Squamous epithelium

Explanation:

Squamous epithelium is thin and flat, suitable for lining surfaces involved in passive transport.

5. Which tissue has cells that are capable of contraction and relaxation?

a) Connective tissue
b) Muscular tissue
c) Epithelial tissue
d) Nervous tissue

Answer:

b) Muscular tissue

6. In which type of cartilage is the matrix solid and provides strength?

a) Hyaline cartilage
b) Fibrous cartilage
c) Elastic cartilage
d) Calcified cartilage

Answer:

b) Fibrous cartilage

Explanation:

Fibrous cartilage has a matrix containing white fibrous tissue; it provides strength.

7. Which type of epithelial tissue is responsible for secretion and absorption in the kidney?

a) Squamous epithelium
b) Ciliated epithelium
c) Columnar epithelium
d) Cuboidal epithelium

Answer:

d) Cuboidal epithelium

Explanation:

Cuboidal epithelium lines the tubules of the kidney and is involved in secretion and absorption.

8. The tissue that transports oxygen to various parts of the body is:

a) Muscle tissue
b) Bone tissue
c) Blood
d) Nervous tissue

Answer:

c) Blood

Explanation:

Blood is a connective tissue responsible for transporting oxygen, nutrients, and other substances.

9. Which type of muscle is involuntary and spindle-shaped?

a) Cardiac muscle
b) Skeletal muscle
c) Smooth muscle
d) Involuntary muscle

Answer:

c) Smooth muscle

Explanation:

Smooth muscle is involuntary, non-striated, and spindle-shaped.

10. The type of epithelial tissue that lines the respiratory tract is:

a) Cuboidal epithelium
b) Squamous epithelium
c) Ciliated columnar epithelium
d) Glandular epithelium

Answer:

c) Ciliated columnar epithelium

Explanation:

The respiratory tract has cilia to move mucus, hence lined by ciliated columnar epithelium.

11. The type of joint present in our elbow is:

a) Pivot joint
b) Hinge joint
c) Ball and socket joint
d) Gliding joint

Answer:

b) Hinge joint

Explanation:

Hinge joints allow a back-and-forth motion, as seen in the elbow and knee.

12. Which tissue acts as an insulator and prevents heat loss?

a) Bone
b) Blood
c) Adipose tissue
d) Muscle

Answer:

c) Adipose tissue

Explanation:

Adipose tissue stores fat and acts as an insulator.

13. Which tissue forms the framework of ears and nose?

a) Hyaline cartilage
b) Elastic cartilage
c) Fibrous cartilage
d) Bone

Answer:

b) Elastic cartilage

Explanation:

Elastic cartilage is flexible and maintains the shape of certain structures.

14. Tendons connect:

a) Muscle to bone
b) Bone to bone
c) Muscle to muscle
d) Nerve to muscle

Answer:

a) Muscle to bone

Explanation:

Tendons are strong, fibrous structures that connect muscles to bones.

15. Which type of epithelial tissue helps in diffusion and filtration?

a) Columnar epithelium
b) Cuboidal epithelium
c) Squamous epithelium
d) Ciliated epithelium

Answer:

c) Squamous epithelium

Explanation:

Due to its thin and flat structure, squamous epithelium facilitates diffusion and filtration.

16. In which animal tissue would you find Haversian canals?

a) Cartilage
b) Bone
c) Blood
d) Muscle

Answer:

b) Bone

Explanation:

Haversian canals are found in compact bone tissue.

17. The muscle which is both voluntary and striated is:

a) Cardiac muscle
b) Skeletal muscle
c) Smooth muscle
d) Involuntary muscle

Answer:

b) Skeletal muscle

Explanation:

Skeletal muscle is under voluntary control and shows striations.

18. Which tissue primarily functions in binding other tissues together?

a) Connective tissue
b) Muscular tissue
c) Epithelial tissue
d) Nervous tissue

Answer:

a) Connective tissue

Explanation:

Connective tissue primarily provides support and binds other tissues together.

19. The inner lining of the mouth is made up of which epithelium?

a) Cuboidal epithelium
b) Squamous epithelium
c) Columnar epithelium
d) Ciliated epithelium

Answer:

b) Squamous epithelium

Explanation:

The inner lining of the mouth has protective squamous epithelium.

20. Which tissue provides a site for the storage of fat?

a) Adipose tissue
b) Cartilage
c) Bone
d) Blood

Answer:

a) Adipose tissue

Explanation:
