Adrenaline, also known as epinephrine, is a vital hormone and neurotransmitter involved in the body’s fight-or-flight response. It plays a crucial role in regulating cardiovascular function, metabolism, and stress responses. This detailed note explores the synthesis, biological roles, and clinical significance of adrenaline. Synthesis of Adrenaline Adrenaline is synthesized from the amino acid tyrosine through … Read more
Definition of Adrenal Gland The adrenal glands, also known as suprarenal glands, are small, triangular-shaped endocrine glands located on top of each kidney. They play a crucial role in producing hormones that regulate metabolism, immune response, blood pressure, stress response, and other vital functions. Â Detailed Anatomy of the Adrenal Gland 1. Location and Structure: … Read more
The endocrine system is a complex network of glands that secrete hormones to regulate various bodily functions, including metabolism, growth, reproduction, and homeostasis. Hormones are chemical messengers that travel through the bloodstream to target organs or tissues, where they elicit specific physiological responses. Here is a detailed note on the classification of hormones and their … Read more
Definition Emergency drugs are medications that are administered in critical or life-threatening situations to address immediate medical needs. These drugs are crucial in various healthcare settings, including emergency departments, intensive care units, and pre-hospital care, where rapid intervention is essential to stabilize patients and prevent further harm. Categories of Emergency Drugs 1. Cardiac Arrest and … Read more
Definition: Shock is a critical medical condition characterized by inadequate blood flow and oxygen delivery to tissues and organs, resulting in impaired cellular function. It is a life-threatening emergency requiring prompt intervention to restore perfusion and prevent organ failure. Classification 1. Vasopressors Vasopressors are a class of medications that constrict blood vessels and raise blood … Read more
The regulation of blood glucose levels is a complex and tightly controlled process involving several hormones. The two primary hormones responsible for maintaining blood glucose homeostasis are insulin and glucagon, both produced by the pancreas. 1. Insulin Source: Produced by beta cells in the pancreas. Function: Stimulates glucose uptake by cells, particularly in the liver, … Read more
Neurotransmitters are chemical messengers that play a crucial role in transmitting signals across synapses in the nervous system. These signaling molecules transmit information from one neuron to another or from neurons to target cells (e.g., muscles or glands). Neurotransmitters can be classified based on various criteria, and each type has specific properties. Here’s a classification … Read more
Epinephrine, also known as adrenaline, is a hormone and neurotransmitter that plays a crucial role in the “fight or flight” response of the sympathetic nervous system (SNS). The adrenal glands, situated on top of each kidney, produce it and release it into the bloodstream in response to stress or danger. Uses 1. Anaphylaxis Treatment: Epinephrine … Read more
The adrenal glands are a pair of small, triangular-shaped glands situated atop each kidney. Comprising two distinct parts—the adrenal cortex and adrenal medulla—the adrenal glands play a crucial role in the body’s response to stress and contribute to various physiological functions. Hormones Produced by the Adrenal Glands Adrenal Cortex Hormones: 1.Cortisol: A glucocorticoid that regulates … Read more
Anti-adrenergic drugs, also known as adrenergic antagonists, are a class of medications that work by inhibiting the actions of norepinephrine and epinephrine, the neurotransmitters that activate adrenergic receptors. Doctors use these drugs to block or counteract the effects of the adrenergic system, reducing the impact of sympathetic nervous system stimulation and treating various medical conditions. … Read more
