Question

Which of the following are general features of all connective tissues? (There may be more than one correct response.)

- Epithelial cells

- Protein fibers in an extracelluar matrix

- Inter-calculated disk 

- Lacunae 

- Striations

- Ground Substance in an extracelluar matrix 

- Specialized cells 

Answer 1

Of the following seven features, only four are associated with connective tissues.

1. Protein fibers and a ground substance in an extracellular matrix provides structure and rigidity to the connect tissue and acts as a medium for substances to pass through.
2. Lacunae are the cavities in bone which is the most rigid connective tissue.
3. Specialized cells consisting of red and white blood cells are associated with the blood.

Epithelial cells are a part of the epithelial tissue that covers the body surface and organs.

Inter-calculated disks and striations are features of muscle tissue.
