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.
Sensory Neurons: Sensory neurons carry signals from the outer part of the body into the central nervous system. Motor Neurons: Motor neurons carry signals from the central nervous system to the outer parts of the body. Afferent/Efferent Pathways. Sensory Neurons: Sensory neurons follow the afferent pathway.
