Question

1. the ability of a skeletal muscle to receive and respond to a nerve impulse is known as ___.

automaticity
contractility
sensitivity
excitability
clear all

Explanation:

• Automaticity refers to the ability of certain cells (like cardiac pacemaker cells) to initiate electrical impulses on their own, not related to skeletal muscle responding to nerve impulses.
• Contractility is the ability of muscle to shorten and produce force, but it doesn't directly address the reception and response to a nerve impulse.
• Sensitivity is a more general term and not the specific property for a skeletal muscle's response to a nerve impulse.
• Excitability is the property of a skeletal muscle (and other excitable tissues like nerve) to receive and respond to a stimulus (such as a nerve impulse).

Answer:

excitability
