Answer: 2) Facilitates gluconeogenesis and lipolysis
Explanation: Cortisol, a glucocorticoid hormone, plays a key role in the fight-or-flight response by mobilizing energy stores. It stimulates gluconeogenesis in the liver and promotes lipolysis in adipose tissue, increasing the availability of glucose and fatty acids for energy production during stressful situations.

1. It is associated with platelet-specific autoantibodies: This statement is true. ITP is characterized by the presence of autoantibodies that specifically target and destroy platelets, leading to thrombocytopenia (low platelet count).

2. It causes a prolonged bleeding time: This statement is true. In ITP, the low platelet count results in a prolonged bleeding time, as there are fewer platelets available to form a clot.

3. It is often controllable by immunosuppressive treatment: This statement is true. ITP can often be managed with immunosuppressive therapies, such as corticosteroids, intravenous immunoglobulin (IVIG), or other immunosuppressive agents, to help increase platelet counts.

4. It causes more prolonged hemorrhage than hemophilia: This statement is not true. While both ITP and hemophilia can lead to bleeding, the mechanisms are different. Hemophilia is a clotting factor deficiency, which can lead to more severe and prolonged bleeding episodes, especially after trauma or surgery. In contrast, ITP primarily affects the number of platelets rather than the clotting factors. Therefore, the bleeding in hemophilia can be more severe and prolonged compared to that in ITP.

Periodontal packs are primarily used for their antimicrobial, haemostatic, and splinting properties. While they provide a good antimicrobial environment and can aid in haemostasis, they are not typically used for pain elimination. The main purpose of a periodontal pack is to deliver medication directly to the periodontal pocket and help stabilize the gum tissue around the teeth. Pain relief is generally managed through other means such as analgesics or local anesthetics.

The Campbell line is an important anatomical reference line used in radiology, particularly in the context of the occipitomental view (also known as the Water's view). This line is drawn from the outer canthus of the eye to the midpoint of the maxillary sinus and is used to assess the position of the maxillary sinuses and other related structures in the skull.
