Which one of the following is not a sensory structure in cockroach?
1 Antennae
2 Eyes
3 Anal cerci
4 Maxillary palps
5 Proventriculus
Explanation:
: Antennae - one of a pair of slendermovablesegmental sensory organ on the head of insect used for sensing odors. - Eyes- A compound eye is a visual organconsist of thousands of ommatidia. - Anal cerci- the \(10^{\text {th }}\) segment of the abdomen contain anal cerci serve as sensory organs but can also used for defence or mating. Maxillary palp- These palps serve as organ of touch and taste in feeding. Proventriculus - The opening of crop is called peritoneum/ proventriculus. It plays a role in digestion.

The lateral sclerite in cockroach is called as:
1 palpiger
2 arthrodial membrane
3 pleuron
4 pellicle
Explanation:
C Lateral sclerite in cockroach is called pleuron. It is a parts of exoskeleton of cockroach which protect the body and prevent loss of water from body. - Dorsal surface of exoskeleton covered by chitinous plate called tergum. - Ventral surface of exoskeleton covered by sternum. - Tergum and sternum connected with the help of pleuron in lateral side.

Which one of the following is the true description about an animal concerned?
1 Rat - Left kidney is slightly higher in position than the right one
2 Cockroach
3 Earthworm
4 Frog 10 pairs of spiracles ( 2 pairs on thorax and 8 pairs on abdomen. The alimentary canal consists of a sequence of pharynxoesophagusstomachgizzard and intestine Body divisible into three regions-headneck and trunk
Explanation:
B There are 10 pairs of spiracles in cockroach. Two pairs are thoracic in which first pair is known as mesothoraciclying infront of the mesothorax between the bases of first and second pair of legs and are the largest. The second pair is called metathoracic. - Abdominal spiracles are eight pairs. The first pair is dorsal in position and lies on the lateral margins of the first abdominal tergum. The remaining are situated on the sides of their corresponding segments in the pleura between the terga and sterna. - Spiracles are mean for intake of fresh air and release of foul air.

Arrange the ganglia of autonomous nervous system of cockroach in correct sequence from anterior to posterior end.
1 \(\mathrm{A}-\mathrm{C}-\mathrm{D}-\mathrm{B}\)
2 \(\mathrm{A}-\mathrm{D}-\mathrm{C}-\mathrm{B}\)
3 \(\mathrm{B}-\mathrm{C}-\mathrm{D}-\mathrm{A}\)
4 B-D-A-C
Explanation:
A (a) Frontal ganglion- This is small median ganglion located dorsally upon the pharynx just in front of the brain. (c) Hypocerebral ganglion- This is also a small median ganglion located dorsally upon the oesophagus behind the brain. (d) Visceral ganglion- This is located mid-dorsally upon the crop at about its middle. (b) Proventricular ganglia- Last ganglia in the nervous system. It is present on the gizzard.
