[Stress and the salivary glands]
Summary
Induced stress causes morphological changes in rat salivary glands. The submaxillary gland is more sensitive to cold stress, while the sublingual gland shows greater sensitivity to immobilization stress.
Area of Science:
- Histology
- Endocrinology
- Physiology
Context:
- Stress impacts physiological systems.
- Salivary glands play roles in homeostasis.
- Understanding stress-induced gland changes is crucial.
Purpose:
- To investigate stress-induced morphological alterations in rat sublingual and submaxillary glands.
- To differentiate gland sensitivity to various stressors.
Summary:
- General adaptation syndrome was induced in Wistar rats using cold and immobilization.
- Animals were assessed 48 hours and 10 days post-stress.
- Histological analysis revealed differential sensitivity: submaxillary glands to cold, sublingual glands to immobilization.
Impact:
- Provides insights into the differential impact of stressors on salivary gland morphology.
- Highlights the submaxillary gland's vulnerability to cold.
- Suggests the sublingual gland is more susceptible to immobilization-induced changes.

The Sympathetic Nervous System
Overview
Hypothalamic-Pituitary Axis
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
Anatomy of the Adrenal Glands
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
Physiological Foundation of Stress
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Stress Response System
The stress response system, also known as the fight-or-flight response, is the body's automatic physiological reaction to perceived threats. Hans Selye introduced the concept of General Adaptation Syndrome (GAS) to describe the predictable pattern of changes that occur in response to stress. GAS consists of three sequential stages: alarm, resistance, and exhaustion. This model helps explain how chronic stress can contribute to health problems.
