in the body.” Once the chemical reaches the brain, it starts to over-activate certain parts of the brain. This can temporarily lead to: altered senses, changes in mood, impaired body movement, difficulty with thinking and problem solving, impaired memory, hallucinations, delusions, and psychosis. The THC can also have a long-term impact on the development of the brain. Marijuana can impair an individual’s thinking, memory, and learning functions. The brain can no longer make connections between…

Peer Assessment 2 Choose one out of paracrine signalling, endocrine signalling, autocrine signalling and direct signalling and describe brie y the process by which this occurs. The Endocrine signalling occurs over long distances in the body and the signal is sent through the blood. Firstly, the cell inside the pituitary gland sends hormones into the blood stream over a long distance and once it gets reaches to a cell with the right receptor, the hormones will attach themselves to the receptor…

Various studies have revealed that specific interventions and therapies after a spinal cord injury can lead to the recovery of movement, even after severe paralysis. When the spinal cord, a thin bundle of nervous tissue, is damaged, signals from the brain that usually travel down the nerves spinal cord to the muscles are interrupted. The nerve fibers in these descending pathways are broken or destroyed and they undergo reorganization to regenerate essential pathways such as those involved…

Spina bifida is a type neural tube defect where the bones of the spine don’t form properly around part of the baby’s spinal cord. There are three types of spina bifida: spina bifida occulta, meningocele, and myelomeningocele. Spina bifida occulta is the mildest and most common form of spina bifida. It is also called hidden spina bifida. There is usually a small gap in the spine, but no opening or sack on the back. It can be recognized by a tuft or clump of hair, a dimple, or a birthmark where…

Along with Steinert, Batten and Gibb were the first to report on what is now known as DM1. Batten and Gribb describe two cases of what they termed myotonia atrophica. Patient 1 was a 37-year-old male while patient 2 is a 56-year-old male. In both cases, the authors note wasting of the sterno mastoids, vastus internus and forearm muscles. Both showed a weakness of the orbicularis paperbarum and stiffness in the jaws and tongues as well as initiation of walking. There was lack of or sluggish…

(AD). Physiologically, AD involves damage to brain cells and their eventual death. It is a progressive and irreversible disorder with no identifiable treatment or real understanding of the mechanisms and molecular determinants involved in the disease process. A majority of the destruction that occurs in AD takes place in parts of the brain that are vital for memory, such as the cortex. In addition, AD is characterized by additional changes in the brain. These include the formation of tangles and…

Subsequently, the categories, in the most basic manner, are episodic and procedural. Episodic for example, is remembering a present given to you. It is a singular event that holds personal…
