Acid
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen ion, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid.
Actin
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.
Action potential
An action potential occurs when the membrane potential of a specific cell rapidly rises and falls.
See Weakness and Action potential
Adenosine diphosphate
Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells.
See Weakness and Adenosine diphosphate
Adenosine triphosphate
Adenosine triphosphate (ATP) is a nucleotide that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis.
See Weakness and Adenosine triphosphate
Brain
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.
Calcium
Calcium is a chemical element; it has symbol Ca and atomic number 20.
Cellular respiration
Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy.
See Weakness and Cellular respiration
Cori cycle
The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
Delayed onset muscle soreness
Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise.
See Weakness and Delayed onset muscle soreness
Eye strain
Eye strain, also known as asthenopia (from Greek a-sthen-opia, ἀσθενωπία), is a common eye condition that manifests through non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision.
Glucose
Glucose is a sugar with the molecular formula.
Glycogen
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria.
HIV
The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans.
See Weakness and HIV
Inflammatory myopathy
Inflammatory myopathy, also known as idiopathic inflammatory myopathy (IIM), is disease featuring muscle weakness, inflammation of muscles (myositis), and in some types, muscle pain.
See Weakness and Inflammatory myopathy
Lactic acid
Lactic acid is an organic acid.
Muscle cell
A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal.
Muscle contraction
Muscle contraction is the activation of tension-generating sites within muscle cells.
See Weakness and Muscle contraction
Muscle weakness
Muscle weakness is a lack of muscle strength. Weakness and muscle weakness are Muscular disorders and Neurological disorders.
See Weakness and Muscle weakness
Muscular dystrophy
Muscular dystrophies (MD) are a genetically and clinically heterogeneous group of rare neuromuscular diseases that cause progressive weakness and breakdown of skeletal muscles over time.
See Weakness and Muscular dystrophy
Myalgic encephalomyelitis/chronic fatigue syndrome
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling chronic illness. Weakness and Myalgic encephalomyelitis/chronic fatigue syndrome are Neurological disorders.
See Weakness and Myalgic encephalomyelitis/chronic fatigue syndrome
Myasthenia gravis
Myasthenia gravis (MG) is a long-term neuromuscular junction disease that leads to varying degrees of skeletal muscle weakness.
See Weakness and Myasthenia gravis
Myosin
Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes.
Nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system.
Nervous system
In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.
See Weakness and Nervous system
Neural coding
Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.
See Weakness and Neural coding
Neurology
Neurology (from νεῦρον (neûron), "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves.
Neuromuscular disease
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit.
See Weakness and Neuromuscular disease
Neuromuscular junction
A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber.
See Weakness and Neuromuscular junction
Organ (biology)
In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function.
See Weakness and Organ (biology)
Pathology
Pathology is the study of disease and injury.
Phosphocreatine
Phosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated form of creatine that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle, myocardium and the brain to recycle adenosine triphosphate, the energy currency of the cell.
See Weakness and Phosphocreatine
Protease inhibitor (pharmacology)
Protease inhibitors (PIs) are medications that act by interfering with enzymes that cleave proteins.
See Weakness and Protease inhibitor (pharmacology)
Pyruvic acid
Pyruvic acid (IUPAC name: 2-oxopropanoic acid, also called acetoic acid) (CH3COCOOH) is the simplest of the alpha-keto acids, with a carboxylic acid and a ketone functional group.
Ritonavir
Ritonavir, sold under the brand name Norvir, is an antiretroviral medication used along with other medications to treat HIV/AIDS.
Sarcoplasmic reticulum
The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells.
See Weakness and Sarcoplasmic reticulum
Serotonin
Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.
Signs and symptoms
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition.
See Weakness and Signs and symptoms
Sliding filament theory
The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement.
See Weakness and Sliding filament theory
Strength training
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve strength and endurance.
See Weakness and Strength training
Substrate (chemistry)
In chemistry, the term substrate is highly context-dependent.
See Weakness and Substrate (chemistry)
Synaptic fatigue
Synaptic fatigue, or short-term synaptic depression, is an activity-dependent form of short term synaptic plasticity that results in the temporary inability of neurons to fire and therefore transmit an input signal.
See Weakness and Synaptic fatigue
