• C. Respiration
• D. Vasodilation

Answer: (B)

Verified step by step guidance

1. Understand the problem: The question is asking for the term that describes the process by which a muscle is stimulated by an impulse transmitted by a motor nerve. This involves the interaction between the nervous system and the muscular system.
2. Review the options provided: The terms are 'Ossification,' 'Innervation,' 'Respiration,' and 'Vasodilation.' Each term has a specific meaning in Anatomy & Physiology, so we need to identify the one that matches the described process.
3. Define each term: 'Ossification' refers to the process of bone formation. 'Innervation' refers to the supply of nerves to a specific body part, including the transmission of impulses to muscles. 'Respiration' refers to the process of gas exchange in the lungs and tissues. 'Vasodilation' refers to the widening of blood vessels.
4. Match the correct term to the description: The stimulation of a muscle by an impulse transmitted by a motor nerve is a process that involves the nervous system sending signals to the muscle fibers, which is described by the term 'Innervation.'
5. Conclude the reasoning: Based on the definitions, 'Innervation' is the correct term because it directly refers to the connection and communication between nerves and muscles, enabling the transmission of impulses for muscle stimulation.
