Verified step by step guidance

Understand the role of hormones: Hormones are chemical messengers that travel through the bloodstream to tissues and organs, affecting various physiological processes.

Identify typical hormonal effects: Hormones can stimulate mitosis, alter plasma membrane permeability, and induce secretory activity. These are common changes associated with hormonal stimuli.

Consider the nature of skeletal muscle contraction: Skeletal muscle contraction is primarily controlled by the nervous system through electrical impulses, not directly by hormonal stimuli.

Differentiate between direct and indirect effects: While hormones can influence muscle growth and metabolism indirectly, they do not directly activate skeletal muscle contraction.

Conclude the analysis: Based on the understanding of hormonal effects and muscle contraction mechanisms, identify that direct activation of skeletal muscle contraction is not typically produced by a hormonal stimulus.
