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.
Therefore, when a signal reaches the relay neuron from the sensory neuron, the relay neurons will directly send a signal to the motor neurons.   The main function of neuron cells are to carry signals.   There are three types of neurons.Sensory, relay, and motor neuron. Sensory neurons carry signals from the r â¦ eceptors in our body (e.g. thermal, pressure etc.) to the relay neurons, which are found in our spinal cord.Relay neurons then send signals along the spinal cord to the brain.herefore, when a signal reaches the relay neuron from the sensory neuron, the relay neurons will directly send a signal to the motor neurons.   The main function of neuron cells are to carry signals.   There are three types of neurons.
