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

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.

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

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

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

Muscles in hollow viscera primarily behave as _____ unit smooth muscles

_____-unit smooth muscle systems respond to hormones and other circulating systems

_____ is an exception to Sherrington's law of reciprocal innervation
