Hyperkalemia is the most immediately dangerous complication of acute renal failure because it can cause fatal cardiac arrhythmias including ventricular fibrillation.

The Trigeminal nerve (CN V) is responsible for motor innervation to the muscles of mastication (chewing). Specifically, the mandibular branch (V3) of the trigeminal nerve innervates muscles such as the masseter, temporalis, and pterygoids. It also provides sensory innervation to the face, but its motor component is critical for jaw movement.

IgA nephropathy (Berger disease) is characterized by mesangial IgA immune complex deposition, presenting with gross hematuria during mucosal infections (within 1-2 days).

Mitochondria are often referred to as the 'powerhouses' of the cell because their primary function is energy production. Through cellular respiration, they generate adenosine triphosphate (ATP), the main energy currency of the cell, from glucose and other fuel molecules. This process is crucial for nearly all cellular activities requiring energy.

High-velocity, low-amplitude (HVLA) thrust is a direct osteopathic manipulative treatment technique. Direct techniques involve moving the dysfunctional body part towards the restrictive barrier, engaging it, and then applying a corrective force. HVLA specifically uses a rapid, therapeutic force of brief duration that travels a short distance within the anatomic range of motion, often resulting in an audible 'pop' or 'click'.

The tenet that 'The body is capable of self-regulation, self-healing, and health maintenance' specifically articulates the osteopathic principle of the body's innate healing capacity. Osteopathic manipulative treatment (OMT) is often aimed at removing somatic barriers to allow this inherent capacity to function optimally. The other options are also core tenets but do not specifically address the self-healing mechanism.
