Draw a neat, labeled diagram of salivary apparatus of cockroach.

The diagram of the salivary apparatus of a cockroach consists of various parts that help in the production and secretion of saliva. The main components include:

1. Salivary Glands:
   • The cockroach has three pairs of salivary glands—two pairs of sublingual glands and one pair of labial glands.
   • These glands secrete saliva that helps in the digestion of food.
2. Salivary Ducts:
   • The saliva from the glands is collected and carried through the salivary ducts to the mouth cavity.
   • The ducts are connected to the salivary glands and are responsible for transporting the saliva to the oral cavity.
3. Salivary Reservoir:
   • The saliva is stored in the salivary reservoir before being secreted into the mouth.

Steps to draw the diagram of salivary apparatus of cockroach.:

1. Draw the head of the cockroach with a clear labeling for parts like the mouth.
2. Inside the head, draw three pairs of salivary glands. Two of them should be drawn beneath the mouth, and the third one near the labium (lower lip).
3. Connect these glands with salivary ducts leading toward the mouth.
4. Show the salivary reservoir located near the glands.
5. Label all the components like the salivary glands, ducts, and reservoir appropriately.
