The dermis‚ or known as the true skin‚ is thick‚ sturdy‚ and contains lots of nerves‚ blood vessels‚ and sweat glands. It protects and repairs injured tissue. This layer holds more collagen‚ which comes from cells called fibroblasts and is one of the strongest proteins found in nature. It gives skin durability and resilience.

fingers between your door‚ are all painful accidents. Pain is the undesirable feeling; the red alert which signals our attention to something unfavorable happening to our bodies. Our bodies can detect pain by nocioceptors. Nocioceptors are special nerve receptors designed for stimuli that are encountered as painful (Benjamin B. Lahey‚ 2009). There are two significant pathways these neural pain messages travel to our brain; fast and slow. The fast and slow pathways are the reason why our bodies

Electrical nerve signals generate the awful symptoms of Parkinson Disease. The neurostimulator works by blocking the abnormal nerve signals that cause tremors and Parkinson Disease Symptoms.

During normal breathing impulses from the Inspiratory Centre stimulate the contraction of external intercostals muscles and diaphragm‚ and inhibit the expiratory system for about 2 seconds. The effect of this is the inflation of the lungs and inspiration. After 2 seconds nerve impulses from the expiratory centre stimulate the internal intercostal muscles and abdominal muscles to contract causing air to

It is connected to wires that are wrapped around the nerve‚ which connects to the brain. It sends electrical impulses to the brain to interrupt the occurrence of a seizure. It gradually worked as they adjusted the device‚ and now I have not had a seizure in a long time. On the other hand‚ it stings when it sends the impulse‚ I cough‚ and lose my voice for a few minutes.

1. A. Homeostasis is defined as a condition of equilibrium in the body internal environment. For example the internal organs‚ behaviors‚ body temperatures. In homeostasis it can be considered as dynamic as it is always changing. The liver‚ kidneys‚ autonomic nervous system and endocrine system‚ and hypothalamus help maintain homeostasis. For example‚ my brother has imbalance homeostasis due to having seizures. Because his brain is not functioning correctly‚ his homeostasis is not balance. B. Medial
