Correct answer: C. Sarcolemma
- A. Nucleus
- B. Axon
- C. Sarcolemma
- D. Cytoplasm
Explanation
The term "sarcolemma" specifically refers to the cell membrane of muscle cells (muscle fibers). It is not used to describe the cell membrane of nerve cells (neurons). Neurons have their own specialized cell membrane, but it is not referred to as sarcolemma.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
