Skin glue is a special type of medical adhesive. It joins the edges of a wound together, while the wound starts to heal underneath. Doctors and nurses may use skin glue to close wounds instead of other methods, such as: 1  stitches (sutures)  skin staples.
Efferent nerve fiber. In the peripheral nervous system, an efferent nerve fiber is the axon of a motor neuron. The nerve fiber is a long process projecting far from the neuron's body that carries nerve impulses away from the central nervous system toward the peripheral effector organs (mainly muscles and glands). A bundle of these fibers is called a motor nerve or an efferent nerve.
Impulses that are sent along neurons are called action potentials. An action potential (also known as an impulse) is the electrical current that travels the length of an axon when a neuron has been stimulated. At rest the membrane inside of a neuron has a negative charge. This is called the resting membrane potential.. axon. The dendrites receive impulses from sensory receptors or other neurons and send them towards the cell body, which contains the nucleus. Impulses are then conducted along the axons full length away from the cell body to connect with the dendrites of another neuron, muscle, organ or gland of some kind.
