How do the conduction velocities of unmyelinated axons compare to myelinated axons?
Unmyelinated axons have slower conduction velocities compared to myelinated axons. Myelinated axons are able to conduct nerve impulses faster due to the insulation provided by the myelin sheath.
The interior of the is white due to the high concentration of myelin-sheathed axons?
Cerebrum
The majority of backaches are due to?
The majority of backaches are due to poor posture and weak supporting muscles.
The interior of the is white due to the high concentration of myelin sheathed axons?
The white matter in the central nervous system appears white due to the high concentration of myelinated axons. Myelin, a fatty substance that surrounds nerve fibers, has a white color and helps speed up the transmission of signals between neurons. This white appearance contrasts with the gray matter, which contains cell bodies and unmyelinated axons.
What is known as the enlargement in the bulk of an organ that is not due to tumor?
hypertrophy
How do nerves get damaged?
Nerves can get damaged due to physical injuries that directly impact the nerves, due to infection by pathogens such as meningococcal bacteria or poliovirus, or due to exposure to poisons such as mercury.
Which type of axon will velocity of action potential conduction be the fastest?
Myelinated axons with a larger diameter will conduct action potentials the fastest due to saltatory conduction, where the action potential jumps from one node of Ranvier to the next, skipping the myelin-covered regions. Smaller-diameter and unmyelinated axons will conduct action potentials more slowly.
What does it mean if the burn still hurts after a week?
Pain travels through nerves. Therefore, the pain you feel is likely due to damaged nerves at the site of contact.
Can to much headbanging to rock music kill brain cells?
Some spread myth that headbanging, "will tear axons in your brain and cause brain cells death." Headbanging can contribute to brain damage but its will be due stroke or maybe concussion but claiming that headbanging tear axons is a joke
What has the author H S Carter written?
H. S. Carter has written: 'On causalgia and allied painful conditions due to lesions of peripheral nerves' -- subject(s): Causalgia, Nerves, Peripheral, Peripheral Nerves, Wounds and injuries
