Nerve and Muscle Physiology — Flashcards

Stretch reflex:The basis of Jendrassik manouvre is that muscle stretch due to _____-motor neuron stimulation, increases the rate of firing of Ia afferent fibres from the muscle spindle

Peroneus tertius acts during the _____ phase of gait along with extensor digitorum longus and tibialis anterior (muscles) to produce dorsiflexion of the foot

Activation of the _____ adrenergic receptor causes contraction of the intestinal and bladder sphincter muscles

Sympathetic stimulation increases the activity of _____ via phosphorylation/inhibition of phospholamban

Withdrawl reflex:In the _____ reflex, the contraction occurs immediately after applying the stimulus and the after-discharge is smaller.

Withdrawl reflex:When a painful stimulus is applied to the body, the flexor withdrawal (on _____lateral side) and the crossed extensor reflexes (on contralateral side) are stimulated.

In a normal person, lateral buttok traction test will lead to _____ of sphincter

Muscles in hollow viscera primarily behave as _____ unit smooth muscles

Changes in muscle strength at the onset of muscle contraction due to repeated stimulus known as _____ effect

_____ is a result of stretch reflex-inverse stretch reflex sequence
