Which statement best describes why neurons and muscle cells are different in their function?

• A. Neurons store energy, while muscle cells generate electrical impulses.
• B. Neurons produce hormones, while muscle cells regulate body temperature.
• C. Neurons are responsible for digestion, while muscle cells are involved in respiration.
• D. Neurons transmit electrical signals, while muscle cells contract to produce movement.

Answer: (D)

Verified step by step guidance

1. Understand the primary functions of neurons and muscle cells: Neurons are specialized cells that transmit electrical signals throughout the nervous system, enabling communication between different parts of the body. Muscle cells, on the other hand, are specialized for contraction, which allows for movement and support of bodily functions.
2. Recognize the role of neurons in the nervous system: Neurons are responsible for processing and transmitting information via electrical impulses. This is crucial for sensory perception, motor control, and cognitive functions.
3. Identify the function of muscle cells in the muscular system: Muscle cells, or myocytes, contract in response to neural signals, leading to movement. This contraction is essential for locomotion, posture maintenance, and various involuntary movements such as heartbeats and peristalsis.
4. Differentiate between the types of signals involved: Neurons primarily deal with electrical signals, which are rapid and allow for quick communication. Muscle cells respond to these signals by converting them into mechanical force through contraction.
5. Conclude with the correct statement: Neurons transmit electrical signals, facilitating communication and coordination within the body, while muscle cells contract to produce movement, supporting various physiological functions.
