E) The eye seeing an image
Resting Membrane Potential
The electrical potential difference across the plasma membrane of a cell in its resting, non-excited state.
Muscle Fiber
An individual muscle cell, known for its elongated form, which contracts to generate movement or maintain posture.
Conducting Neuron
Neurons that transmit electrical impulses throughout the nervous system, facilitating communication between different parts of the body.
- Understand the electrical properties of muscle cells, including action potentials, resting membrane potential, and the role of ion channels.
