This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal o...

Central Nervous System White Blood Cells
1,504 wordsThe name itself is revealing: multiple, more than one, and sclerosis, which refers to areas of sclerotic (scarred) tissue. Multiple sclerosis is a demyelinating disease of the white matter of the central nervous system. These areas of sclerosis, also referred to as lesions or plaques, occur in the white matter of the central nervous system. Gray matter consists primarily of nerve cells. Axons (nerve fibers) are the connections between the cell body and the muscles, sensory organs, and primary or...

1,508 wordsThe only multi-cellular animals without a nervous system are sponges. They do not have any nerve cells or sensory cells. Despite this, touch or pressure to the outside of a sponge will cause a local contraction of its body.

Central Nervous System Spinal Cord
888 wordsSpinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
