HUMAN AS A COMPLEX ORGANISM The human body is a complex system of cells‚ most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve: deriving energy from food‚ protection against injury‚ internal coordination‚ and reproduction. The continual need for energy engages the senses and skeletal muscles in obtaining food‚ the digestive system in breaking food down into usable compounds and in disposing

counterbalance the additional adrenaline‚ the brain produces a neurotransmitter called GABA which is the most important inhibitory neurotransmitter in the central nervous system. It helps the neurons mend after transmission‚ and decrease anxiety and stress. GABA is a significant mood modulator and has inhibitory effects upon the nervous system. (NeuroGenesis‚ 2011) Glutamate is the major excitatory neurotransmitter in the brain which is necessary for learning and memory. When glutamate is at a low level

The nervous system is affected because the motor neurons will stop working which makes it harder for the muscular system to do its job. The nerve cell make an important chemical called dopamine which sends signal to the brain for movement without the nervous system the body will be hard to move because if the dopamine can’t end the signal the body can’t move which can be very difficult. The muscular system permits movement and circulate blood if the muscular system stop working it can

what affect the nervous system play? What about the effects of fear‚ aggression and anxiety they have on the specified behavior? Regulatory behavior is defined as efforts of organisms which are aimed at achieving physiological balance by maintaining basic‚ primary needs. The nervous system functions in conjunction with regulatory behavior. However the nervous system has two parts. They are the central nervous system and peripheral nervous system. The central nervous system is the basic

If the stimulation exceeds the cell’s threshold‚ a new impulse begins. 7. The autonomic nervous system regulates activities that are involuntary. 8. I don’t know. I’m really tired. Maybe. 9. The hypothalamus is the brain structure that acts as a control center for recognition and analysis of hunger‚ thirst‚ fatigue‚ anger‚ and body temperature

Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are

Lemon Grass Lemon Grass is a magical herb that is very useful in many ways. It have lots of benefits if uses in right direction and proper way. A 2005 study by Ben Groin University of the Negev found that the oil from lemon grass caused cancer cell death. According to the Sun Star Network‚ lemon grass may have diuretic properties and can help with digestion. Lemon grass can also help you lose weight‚ particularly when mutual with a well diet and regular physical movement. Health Benefits of Lemon

disorder named after George Guillain (1876- 1961) and Jean Barre (1880- 1967)‚ who were the first people to describe and start to understand the disorder. GBS is a disorder in which the immune system attacks part of the peripheral nervous system‚ which is made up of nerves that extend out from the central nervous system. There are multiple names for this disorder for example it may be called‚ Acute Idiopathic Polyneuritis‚ Acute Inflammatory Demyelination‚ and Landry- Guillain-Barre syndrome. Guillain-

This is accomplished by stroking the skin with a firm movement and by manipulating the muscles. These movements are executed over the body as a whole. The intention is to move everything towards the heart. This increases movement of the internal systems of the body‚ and provides better results of the massage.

cholinergic nerves. Acetylcholine is found in both the peripheral nervous system and the central nervous system. Acetylcholine can also be found in the autonomic nervous system and is the only neurotransmitter used in motor division of the somatic nervous system. In the peripheral nervous system acetylcholine plays a role in skeletal muscle movement‚ as well as in the regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved in the sleep-wake
