Nerve and Muscle Physiology — Flashcards

_____ motoneuron lesions may cause hypo-reflexia

The _____ in neurons, known as Nissl bodies, synthesize peptide neurotransmitters for secretion

_____ of the knee is brought by the action of vastus medialis muscle.

Stretch reflex:Input from the muscle spindle afferents _____ and II, activate the alpha motor neurons, which innervate the extra-fusal fibres

Autonomics _____ Ach receptors are ligand-gated Na+/K+ (ion) channels

In the muscle stretch reflex, stretch increases afferent impulses via _____ and II nerve fibers

A sustained contraction with little expenditure of energy is made possible by a _____ mechanism in smooth muscle

Stretch reflex:Activation of _____ motor neurons leads to direct contraction of the muscle

Post-ganglionic sympathetic neurons utilize _____ as a neurotransmitter in sweat glands

Stretch reflex:Activation of _____ motor neurons leads to indirect contraction of the muscle
