FAQs on Detailed Overview: Salivary Glands Video Lecture - Biology for Grade 11
| 1. What are salivary glands and their functions? |  |
Ans. Salivary glands are the glands located in the mouth and throat that produce saliva. Saliva helps in the digestion of food, lubrication of the mouth, and protection against bacteria. The three main pairs of salivary glands are the parotid glands, submandibular glands, and sublingual glands.
| 2. What conditions can affect the salivary glands? | |
Ans. Several conditions can affect the salivary glands, including salivary gland infections, salivary gland stones, salivary gland tumors, Sjogren's syndrome (an autoimmune disorder), and salivary gland ductal obstruction. These conditions can cause symptoms like swelling, pain, dry mouth, and difficulty in swallowing.
| 3. How are salivary gland disorders diagnosed? | |
Ans. Salivary gland disorders are diagnosed through a combination of physical examination, medical history assessment, and diagnostic tests. The doctor may examine the size and tenderness of the glands, check for the presence of stones or tumors, and order tests such as salivary flow rate measurement, ultrasound, CT scan, MRI, or a biopsy to confirm the diagnosis.
| 4. What are the treatment options for salivary gland disorders? | |
Ans. The treatment for salivary gland disorders depends on the underlying cause. Infections may be treated with antibiotics, while salivary gland stones may require removal through techniques like sialendoscopy or surgery. Tumors may be treated with surgery, radiation therapy, or chemotherapy. In cases of Sjogren's syndrome, symptomatic relief through medications and lifestyle changes is usually the focus of treatment.
| 5. Can salivary gland disorders be prevented? | |
Ans. While some salivary gland disorders may not be preventable, there are certain measures that can reduce the risk. Maintaining good oral hygiene, drinking plenty of water, avoiding excessive caffeine and alcohol consumption, and avoiding tobacco products can help in reducing the chances of developing salivary gland disorders. Regular dental check-ups and prompt treatment of any oral infections are also important preventive measures.
