Biology: Action Potential and Spinal Cord Essay - 2528 Words.
The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex. It is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes.
First to develop is the neural plate followed by formation of a neural groove in the neural plate very shortly. This is then followed by joining of the edges of the neural groove to form a neural tube, which later develops into the brain at the frontal part while the following part develops into the spinal cord.
Essay On Spinal Cord Injury 1476 Words 6 Pages Background and Rationale: Spinal cord injury (SCI) is a devastating and debilitating condition caused by a traumatic blow to the spine.
The neural arch is form from the mesenchymal cells surrounding the neural tube while those cells in the body wall form the costal processes that form ribs in the thoracic region. Chondrification begins in week six. Ossification begins before birth and end during the 25th year.
Spina bifida is caused by the malformation of the spinal cord. The disease is also called neural tube defect. The condition can be sever or mild. The mild spina bifida is common than the sever one.
Spina bifida is when a baby's spine and spinal cord does not develop properly in the womb, causing a gap in the spine. Spina bifida is a type of neural tube defect. The neural tube is the structure that eventually develops into the baby's brain and spinal cord.
Primary (mechanical) phase. The primary phase essentially involves the mechanical disruption of the normal architecture of the spinal cord. Damage to neurons glial cells, and demyelination of spinal tracts leads to anatomical discontinuity.() The extent of the initial impact and degree of neuronal damage is the most crucial determining factor in functional outcome.
