Daily Practice Sheet - 202: Neural Control and Coordination

The document contains a daily practice sheet with 14 multiple choice questions about neural control and coordination. It tests knowledge of topics like neurotransmitters, membrane potentials, reflexes, parts of the eye and ear, and parasympathetic innervation. For each question, the correct answer is provided. The questions cover topics like the chemicals released at synapses, ion distribution and membrane potentials, mechanisms maintaining resting potential, organs controlled by the sympathetic and parasympathetic systems, structures involved in reflexes, areas of the brain associated with emotions, layers of the eyeball, glands in the ear canal, parts of the inner ear responsible for hearing, identification of eye structures, labeling parts of the middle ear, identifying scalae of the coch
