Question

Which of the following statements about the cells of the mucous membrane lining your breathing tubes if false? they manufacture secretory products they form an abrasion resistant covering they are cuboidal or columnar in shape Othey carry cilia that sweep mucus up and out of the respiratory system Question 6 1 pts Which of the following is not true of a typical skeletal muscle? it can be contracted at will it is attached to bones by tendons it can be enlarged by exercise its individual cells can sustain contractions longer than smooth muscle cells can

Answer 1

5 . The answer is ------- they form an abrasion resistant covering .

Explanation :

The nasal mucous membrane is not resistant to abrasions. One of the complication of the intubation is nasal abrasion. Mucous membrane are vulnerable for abrasion .

While the other options are correct.

• Mucus membrane lining the nasal tubes manufacture secretory products. They are made up of cubodial or columnar epithelial cells and they carry cilia that sweep mucus up and out of respiratory tract.

6 . The answer is ----- its individual cells can sustain contractions than smooth muscle can.

Explanation :

Smooth muscle can sustain contraction for  longer period of time than skeletal muscle.

While the other options are correct.

• Skeletal muscle is voluntary muscle and can be contracted by our will and can be strengthened and enlarged by exercise and they are connected to bones by tendons.

Thank you.
