Central Nervous System (CNS) The CNS is responsible for coordinating and controlling the activities of our body such us control of the muscles and the mental activity. The main organs of the CNS is the brain‚ spinal cord‚ and nerves. These organs mostly consist of Nervous Tissues. http://www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/19588.jpg Nervous Tissues Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia. The main functions of nervous tissues

of the brain and spinal cord. Neurones are found throughout the body with the majority found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of

Neuronal and behavioural changes are closely linked to the environment surrounding animals and humans‚ as well as to their lifestyles. This essay will present some evidence that the nervous system of animals and humans have evolved as to maximize survival‚ by looking at specific elements of the nervous system on a cellular level‚ within the brain regions‚ through functioning pathways‚ systems and finally‚ behaviour

The Nervous System and Aging Sensory changes can influence the way we see‚ hear‚ taste‚ smell‚ and respond to touch and pain. This in turn affects how we experience the world and react to things. A significant sensory change can rob us of many simple pleasures and complicate the tasks of daily living. It may mean reduced mobility‚ increased dependence on others‚ inaccurate perception of the environment‚ reduced ability to communicate and socialize‚ or loss of self-esteem. Sensory changes vary

Bones also work for alternative body systems for example the blood cells develop in their fatty inner tissue (red marrow). The body draws from mineral stores in bones during crucial times of shortage‚ for instance when calcium is needed for healthy nerve functioning. The skeletons key components are ligaments‚ the axial skeleton; this consists of the skull‚ spine‚ ribs‚ and breast bone. The appendicular
