Select the correct sequence of organs in the alimentary canal of cockroach starting from mouth:
| 1. | Pharynx → Oesophagus → Ileum → Crop → Gizzard → Colon → Rectum |
| 2. | Pharynx → Oesophagus → Crop → Gizzard → Ileum → Colon → Rectum |
| 3. | Pharynx → Oesophagus → Gizzard → Crop → Ileum → Colon → Rectum |
| 4. | Pharynx → Oesophagus → Gizzard → Ileum → Crop → Colon → Rectum |
The type of epithelial cells which line the inner
surface of fallopian tubes, bronchioles and small
bronchi are known as :-
1. Squamous epithelium
2. Columnar epithelium
3. Ciliated epithelium
4. Cubical epithelium
The terga,sterna and pleura of the cockroach body are joined by:
1. cementing glue
2. muscular tissue
3. arthrodial membrane
4. cartilage
The function of the gap junction is to?
| 1. | Perform cementing to keep neighbouring cells together |
| 2. | Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules |
| 3. | Separate two cells from each other |
| 4. | Stop substances from leaking across a tissue |
Which type of tissue is correctly matched with its location?
| Tissue | Location | |
| 1. | Areolar tissue | Tendons |
| 2. | Transitional epithelium | Tip of nose |
| 3. | Cuboidal epithelium | Lining of stomach |
| 4. | Smooth muscle | Wall of intestine |
| 1. | Presence of a boat shaped sternum on the 9th abdominal segment |
| 2. | Presence of caudal styles |
| 3. | Forewings with darker tegmina |
| 4. | Presence of anal cerci |
The male and female cockroaches can be distinguished by their:
1. size
2. wings
3. anal styles
4. color
Which of the following statements is not correct with respect to the epithelial tissue?
1. It covers the external surface of the body and the internal surface of many organs.
2. The neighbouring cells are held together by cell junctions and there is very little intercellular material.
3. The epithelial cells rest on a cellular basement membrane that separates it from underlying connective tissue.
4. There is no blood vessel supplying the nutrients to the epithelial cells.
