Definition Protein Kinase is an enzyme that modifies other proteins by chemically adding phosphate groups. Expanded Explanation Protein kinases play a vital role in controlling various cellular processes. By adding phosphate groups to proteins – a process called phosphorylation – they regulate protein function. This way, they contribute to numerous cellular operations, including cell division, […]

Definition Homeostasis is a biological process that allows an organism to maintain a stable internal environment despite changes in external conditions. Expanded Explanation Homeostasis is regulated through a complex system of feedback mechanisms that involve the endocrine and nervous systems. These mechanisms adjust physiological processes to maintain optimal levels of temperature, pH, hydration, and nutrient

Definition Bi-level Positive Airway Pressure (BiPAP) actively aids individuals with respiratory conditions, facilitating easier breathing through non-invasive ventilation therapy. Expanded Explanation BiPAP machines deliver pressurized air through a mask to the user’s airways, keeping them open and preventing apneas. The “bi-level” refers to the machine providing two different levels of pressure – a higher pressure

Definition The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats approximately every 24 hours. It can refer to any biological process that displays an endogenous, entrainable oscillation of about 24 hours. Expanded Explanation The “body clock” or circadian rhythm is an internal timing system governing our daily physiological cycles.

Definition Thermoregulation is the process by which an organism maintains its body temperature within certain boundaries, even when the surrounding temperature is very different. Expanded Explanation Temperature regulation involves a balance between heat production and heat loss, ensuring an optimal physiological functioning. It’s crucial in maintaining homeostasis in the body, which is the state of

Definition Obstructive Sleep Apnea (OSA) often interrupts breathing during sleep. This common disorder results from blockages in the upper airways. Expanded Explanation OSA occurs when the muscles supporting the soft tissues in the throat, such as the tongue and soft palate, temporarily relax. This leads to the closure of the airways, restricting the flow of

Definition Total Daily Energy Expenditure (TDEE) refers to the total amount of energy, measured in calories, that a person expends in a day. Expanded Explanation TDEE is the sum of all the energy used by the body throughout the day. It consists of the energy used during rest (Basal Metabolic Rate), physical activity, and food

Definition Thermogenesis is the metabolic process by which organisms produce heat as a result of food metabolism, exercise, or exposure to cold environments. Expanded Explanation It is a crucial physiological process that helps maintain body temperature, contributing to homeostasis. It occurs in three primary forms: exercise-associated thermogenesis (EAT), non-exercise activity thermogenesis (NEAT), and diet-induced thermogenesis

Definition Sleep hygiene refers to a set of habits and practices that are conducive to sleeping well on a regular basis. Expanded Explanation It involves various aspects such as maintaining a regular sleep schedule, creating a restful environment, and managing lifestyle factors that may influence sleep. These practices are critical for ensuring quality sleep, which

Definition Continuous Positive Airway Pressure (CPAP) is a treatment method commonly used for managing sleep apnea, a condition that causes interrupted breathing during sleep. Expanded Explanation CPAP works by continuously delivering pressurized air to the patient’s airway to prevent it from collapsing, which is what occurs in sleep apnea. The pressurized air is delivered through
