Verified step by step guidance

Identify the primary functions of muscle cells and nerve cells. Muscle cells are specialized for contraction, which allows movement and force generation. Nerve cells, or neurons, are specialized for transmitting electrical signals, which facilitate communication within the nervous system.

Understand the structural differences that support these functions. Muscle cells contain proteins like actin and myosin that enable contraction. Nerve cells have long extensions called axons and dendrites that help in transmitting signals over distances.

Consider the presence of synaptic vesicles. These are found in nerve cells at the synapse, where they release neurotransmitters to communicate with other neurons or muscle cells. Muscle cells do not contain synaptic vesicles.

Examine the role of the myelin sheath. This is a fatty layer that insulates nerve cell axons, speeding up the transmission of electrical signals. Muscle cells do not have a myelin sheath.

Evaluate the involvement in sensory perception. Nerve cells are directly involved in sensory perception as they transmit sensory information to the brain. Muscle cells do not play a direct role in sensory perception.
