Compare and contrast epidural and subdural hemorrhages.

Epidural hemorrhages:

Epidural hemorrhage causes the laceration of middle meningeal artery. Temporal bone is mainly associated in this type of hemorrhage. Individual may suffer from loss of consciousness. Neurosurgery is important to treat the epidural hemorrhages.

Subdural hemorrhage:

Subdural hemorrhage causes the rupture of bridging veins. Dura matter of brain is  mainly associated in this type of hemorrhage. Individual may suffer from minor head trauma. Neurosurgery is important to treat the epidural hemorrhages as well.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

it takes hundreds of years to become stable.

if you have another question lmk.
