The metabolic process providing my energy while I was walking at an easy pace is aerobic metabolism. During aerobic metabolism‚ mitochondria absorb from the surrounding cytoplasm these molecules: ADP‚ phosphate ions‚ O2‚ and organic substances like pyruvate. These molecules go through the citric acid cycle. The electron

of the disease varies with each person. A. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease according to the ALS Association that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die‚ the ability of the brain to initiate and control

Mandibular bone fracture is the tenth most common fracture in the human body and second most of the facial bones next only to nasal bones. Among the mandibular bone fractures‚ condylar region is the most frequent site accounting for about 25-35 %.1 Condylar fractures are usually the result of a direct blow to the chin or to the lateral side of the jaw caused by Road traffic accidents‚ violence‚ accidental falls and sporting injuries

These organ systems are dependent on each other to keep the human body in homeostasis. For example‚ the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of the brain‚ nerves and spinal cord. It is the fast acting control
