Explanation:
Γ-Aminobutyric acid (GABA) is a non-protein amino acid that is widely present in microorganisms, plants and animals. It is the main inhibitory neurotransmitter in the central nervous system (CNS) of mammals.
It plays the leading role in reducing neuronal excitability throughout the nervous system. In humans, GABA is directly responsible for the regulation of muscle tone.
Although, in chemical terms, it is an amino acid, in the scientific and medical communities they rarely refer to GABA as such because the term "amino acid" by convention refers to the α amino acids and GABA is not. It is also not considered as part of any protein.
In spastic diplegia in humans from an early age, GABA absorption is negatively affected by the nerves damaged by the lesion in the upper motor neurons characteristic of the condition which leads to the development of muscular hypertonia signaled by those nerves that are incapable of absorbing GABA.
Answer:
An isometric training is a static contraction of a muscle.
Explanation:
An isometric training is a type of exercise which involves the static contraction of a muscle where no visible movement in the angle of the joint occur. Isometric exercises helps in maintaining and recovery of strength of our body. They can also build strength, but not very effectively like other exercises. During isometric training, the muscles doesn't change its length and the affected joint doesn't move from its place.
The development of cell theory serves to show the rigorous activities that must be accomplished before a theory can be developed. A scientific theory is a tested and acceptable explanation for a particular observation. A scientific theory usually started as an observation. The observation is use to formulate an hypothesis which is then tested by carrying out an appropriate experiment. If the experiment confirms the hypothesis to be true, then other scientists from different parts of the world will carry out their own experiments in order to confirm the result of the experiment.
When the result of the experiment has been tested continuously for a long time and find to be true, then it becomes a theory. This is the chains of activities which the observations made in cells undergo before it becomes cell theory.
Answer:
C. Endocrine System
Explanation:
Simply put, the endocrine system is a network of glands that secrete chemicals called hormones to help your body function properly. Hormones are chemical signals that coordinate a range of bodily functions. The endocrine system works to regulate certain internal processes.
Answer:
Circulatory System
Explanation:
As soon as 5he digestive system has broken down the foods to their smallest unit, the circulatory system helps to move the nutrient to where they are needed.
Blood is a medium of transport in higher vertebrates and is being pumped by the heart and flows through network of capillaries. Blood also transport oxygen that helps in the breakdown of carbohydrates to produce energy and get rid of waste such as carbondioxide through the excretory system.
