1. the cockroach does not have nervous system.
2. the head holds a small proportion of a nervous system while the rest is situated along the ventral part of its body.
3. the head holds a 1/3rd of a nervous system while the rest is situated along the dorsal part of its body.
4. the supra-oesophageal ganglia of the cockroach are situated in ventral part of abdomen.

Cuboidal epithelium with brush border of microvilli is found in

1. Ducts of salivary gland
2. Proximal convoluted tubule of nephron
3. Eustachian tube
4. Lining of intestine

Goblet cells of alimentary canal are modified from

1. Columnar epithelial cells
2. Compound epithelial cells
3. Squamous epithelial cells
4. Chondrocytes

Select the correct sequence of organs in the alimentary canal of cockroach starting from mouth:

1. Pharynx Oesophagus Gizzard Ileum Crop Colon Rectum
2. Pharynx Oesophagus Ileum Crop Gizzard Colon Rectum
3. Pharynx Oesophagus Crop Gizzard Ileum Colon Rectum
4. Pharynx Oesophagus Gizzard Crop Ileum Colon Rectum

The ciliated epithelial cells are required to move particles or mucus in a specific direction. In humans, these cells are mainly present in:

1. Eustachian tube and Salivary duct
2. Bronchioles and Fallopian tubes
3. Bile duct and Bronchioles
4. Fallopian tubes and Pancreatic duct
