This document contains a quiz on topics related to the nervous system, including nervous tissue histology, membrane potentials, synapses, neurotransmitters, and other fundamentals. It asks multiple choice questions on these topics and provides explanations for the answers. The questions cover topics such as the cells involved in myelination, ion gradients during resting potentials, the phases of action potentials, and classifications of neurotransmitters.
Human Anatomy is fundamental to every medical and healthcare professional. However, the science of anatomy and effects of stroke are also extremely useful to anyone interested in understanding more about the human body. In this course, you’ll gain an understanding of the basic concepts of anatomy and learn to ‘dissect’ the human body with a logical approach through
