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.
All are made of various specialized neurons. A motor neuron is defined by its efferent function: it carries signals away from the central nervous system. In contrast, afferent nerves carrying signals toward the spinal cord and brain are called sensory neurons.he function of a motor neuron is perfectly suited to the function of muscles. The electrical signal they transmit is either positive or negative. Muscles also have a binary state â contract or relax. Ad.
