An action potential (also known as a nerve impulse or "spike" when in a neuron) is a series of quick changes in voltage across a cell membrane. An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. [1] This depolarization then causes adjacent locations to similarly depolarize.
Achilles' Wrath is a concert piece by Sean O'Loughlin. [99] Temporary Like Achilles is a song on the 1966 double-album Blonde on Blonde by Bob Dylan; Achilles Last Stand is a song on the 1976 Led Zeppelin album Presence. Achilles, Agony and Ecstasy in Eight Parts is the first song on the 1992 Manowar album The Triumph of Steel.
Agamemnon (Ἀγαμέμνων), King of Mycenae, supreme commander of the Achaean armies whose actions provoke the feud with Achilles; elder brother of King Menelaus. Ajax or Aias (Αίας), also known as Telamonian Ajax (he was the son of Telamon) and Greater Ajax, was the tallest and strongest warrior (after Achilles) to fight for the Achaeans.
When a reflex arc in an animal consists of only one sensory neuron and one motor neuron, it is defined as monosynaptic, referring to the presence of a single chemical synapse. In the case of peripheral muscle reflexes (patellar reflex, achilles reflex), brief stimulation to the muscle spindle results in contraction of the agonist or effector ...
Time course of neuronal action potential ("spike"). Note that the amplitude and the exact shape of the action potential can vary according to the exact experimental technique used for acquiring the signal. Biological neuron models, also known as spiking neuron models, [1] are mathematical descriptions of the conduction of electrical signals in ...
Rheobase is a measure of membrane potential excitability. In neuroscience, rheobase is the minimal current amplitude of infinite duration that results in the depolarization threshold of the cell membranes being reached, such as an action potential or the contraction of a muscle. [1]
A weekly shot form of Leqembi, given as two consecutive injections, could simplify use of the groundbreaking Alzheimer's treatment, potentially allowing patients to receive the drug at home ...
Later on in life, Achilles is killed by Paris when he is shot in his vulnerable spot, the heel. This is where the term "Achilles' heel" is derived from. Peleus gave Achilles to the centaur Chiron, to raise on Mt. Pelion, which took its name from Peleus. In the Iliad, Achilles uses Peleus' immortal horses and also wields his father's spear.
