The nervous system relies on the function of neurons to relay messages. Neurons are highly excitable and complex cells that differ in structure and send these messages in the form of nerve impulses from one part of the body to another and allow cells to communicate Neurons consist of a single axon, which is responsible for the generation of the nerve impulses, these nerve pulses are also known as action potential. For action potential to stimulate it relies on membrane ion channels. Many channels

modifies the genetics' structure of an organism by making changes to DNA. This new creation of DNA is injected in plants, animals, or humans, in order to create enhanced crops, animals, or prevent genetic diseases. One of the major fields in genetic engineering is the human field. According to Asch, a biochemistry researcher in Canada, the study of genetic modification in humans involves changes in the DNA, in order to prevent disease, alter human body structure, and changes the human him/herself (Asch

that lies between the deep structures of the cerebral hemispheres and the cervical spinal cord. It is divided into three sections: midbrain, Pons and medulla oblongata. The brain stem also connects to the integumentary system because when you break skin which is part of the integumentary signal is sent to your brain that something is wrong.

the spinal cord. Both parts are encased in bone for protection and further protected from shocks by cerebrospinal fluid which circulates throughout the brain and the spinal cord. o The brain responds to information it receives from the rest of the body. Communication within the brain is two-way; (1) the brain receives and processes information and (2) then forwards the information with instructions on how to respond. o In the brain, a network of individual cells called neurons receives information

“Leonardo da Vinci epitomized the Renaissance, living, thinking and creating art and creating technology, that still characterizes that age of discovery. He typified the free spirit and zest for life and nature of the ultimate Renaissance man.” He was an extraordinarily genius who applied the scientific method to every aspect of life, including art and music. His thirst for knowledge did not stop there he also advanced anatomy to unknown levels. Initially, Leonardo learned anatomy from the old Greeks

or properly: the state of being sound in body or mind. Water is the most important and abundant inorganic compound in all living systems. Although humans might be able to survive for weeks without food, without water you would die in a matter of days. Nearly all the body’s chemical reactions occur in a watery medium. Water has many properties that make it such as indispensable compound for life. Nutrients are chemical substances in food that body cells use for growth, maintenance, and repair

Human cloning is the process of somatic cell nuclear transfer to create a human embryo which has the potential to be implanted into a woman's uterus and develop into a child. http://search.proquest.com/docview/274730164?accountid=152046 Pro Con Intro. The debate is usually divided into two issues -- reproductive cloning (creating cloned human beings) and therapeutic cloning (creating cloned human embryos for research and destruction). For now, there is near-universal consensus that we should

What defines us as humans? Calling ourselves human is our way of categorizing ourselves as a superior species. Although we are distinctly different, we should accept that we are in the same family as chimpanzees. Acknowledging that fact doesn't mean you are calling yourself a chimp. For example, a dog isn't a wolf even though they are from the same family. We are humans. What is it about our physical and behavioral traits that enable us to develop uniquely human capabilities? Traits like language
