Differences in transmitter release and number of nerve terminals per motoneuron between two frog muscles.
Recent studies suggest that the number of nerve terminals maintained per motoneuron and perhaps other motoneuron properties (Grinnell and Herrera, 1980a; Grinnell and Trussell, 1983) influence transmitter release. We have examined, in detail, the structure and function of motoneurons innervating two different twitch muscles, the sartorius and the ext. long. dig. IV (e.l.d.) in the adult frog us...
متن کاملThe tight relationship between asymmetric signaling and locational excitability in motoneuron dendrites
Spinal motoneurons possess large, highly branching dendritic structures that contain thousands of synaptic contacts and various voltage-gated ion channels (VGICs). Research has indicated that dendritic arborization and cable properties provide the basis for foundational dendritic processing, which is characterized by direction-dependent signal propagation and location-dependent channel activati...
متن کاملReduced motoneuron excitability in a rat model of sepsis.
Many critically ill patients in intensive care units suffer from an infection-induced whole body inflammatory state known as sepsis, which causes severe weakness in patients who survive. The mechanisms by which sepsis triggers intensive care unit-acquired weakness (ICUAW) remain unclear. Currently, research into ICUAW is focused on dysfunction of the peripheral nervous system. During electromyo...
متن کاملRelationship between Modified Ashworth Scale and Alpha Motoneuron Excitability in Spinal Cord Lesions
Background: Spasticity is one of the major neurological complications occurring in people with Spinal Cord Lesions due to loss of supra-spinal and spinal control over alpha motor neuron activity. Its accurate assessment is necessary for tailoring patient specific rehabilitation program. Clinical assessment is commonly done through Modified Ashworth Scale where in the examiner subjectively judge...
متن کاملControl of soleus motoneuron excitability during muscle stretch in man.
The relative contributions of intramuscular and extramuscular receptors to changes in the reflex excitability of soleus motoneurons, following muscle stretch, have been studied in man. It was found that reflex excitability was decreased by muscle stretch. The extent of the decrease was related to the amount of stretch, irrespective of whether the latter was produced by dorsiflexion of the ankle...
