According to Albany University, nerve cells have a distinctive long, thin shape because they must be able to transmit impulses over long distances. Nerves pick up electrical impulses from all over the body, and these impulses must travel along an unbroken path to reach the brain.Continue Reading
Centre of the Cell Science Lab explains that nerve cells in the body can reach up to 40 inches in length. Nerve cells in the brain are much shorter but have many branching pathways that also allow them to cover a lot of area.
According to Brown University, the unique shape of nerve cells plays a role in their inability to reproduce.Learn more about Nerves
The function of the myelin sheath is to facilitate the conduction of electrical impulses through the nerve cells. The myelin sheath is made out of a modified plasma membrane that is wrapped around the nerve axon in a spiral pattern.Full Answer >
Sensory neurons receive impulses and carry messages from the sense organs to the brain. Once the brain receives this information, it sends new information to the motor nerves to tell them what actions to perform.Full Answer >
The BBC describes a reflex arc as the nerve pathway through which neural impulses travel to cause a quick autonomic response known as a reflex. Reflexes are not something people think about, rather, they are impulsive reactions to stimuli.Full Answer >
The sensory system is responsible for detecting stimuli from the outside world and transferring nervous impulses to the correct portion of the brain or spinal column to allow the body to react. The sensory system consists of the eyes, ears, nose, tongue, skin and their associated nerves.Full Answer >
