Nervous system By : Dylan aguilar
All the organs of the nervous system • Brain • Spinal cord • Sensory organs • All the nerves
All the functions of the nervous system • The nervous system only has 2 functions • The central nervous system {cns} is made up of the brain and the spinal cord. It is in a medial position and is responsible for interpreting incoming information and issuing instructions based on past experiences • The peripheral nervous system, which lies outside of the cns. It contains 2 main division: the somatic nervous system and the autonomic nervous system. The somatic system sends message from the cns to the skeletal muscles. The autonomic system transmits messages from the cns to the smooth muscles, the cardiac muscles, and certain glands
other Body systems it works with and how they work together • Endocrine system- control the creation of specific hormones and enzymes • Skeletal system- Bones provide calcium that is essential for the proper functioning of the nervous system. • Muscular system- Receptors in muscles provide the brain with information about body position and movement. • Urinary system-the bladder sends sensory information to the brain • Respiratory system- the brain moniters respiratory volumes blood gas levels • http://www.biology4kids.com/files/systems_nervous.html • https://faculty.washington.edu/chudler/organ.html
How does the body system works • The nervous system is a network of cells called neurons which transmit information in the form of electrical signals. Your brain has around 100 billion neurons, and each communicates with thousands of others – as many connections as in the world's telephone system, the biggest machine on the planet. Neurons communicate with each other at special junctions where chemicals help to bridge the gap between one neuron and the next. • http://www.sciencemuseum.org.uk/whoami/findoutmore/yourbrain/howdoesyourbrainwork/howdoesyournervoussystemwork.aspx
What are neurons and how they communicate • The human brain contains about 100 billion neurons. A neuron consists of a cell body containing the nucleus, and special extensions called axons and dendrites • Neurons communicate with each other using axons and dendrites. When a neuron receives a message from another neuron, it sends an electrical signal down the length of its axon. At the end of the axon, the electrical signal is converted into a chemical signal, and the axon releases chemical messengers called neurotransmitters • http://www.nichd.nih.gov/health/topics/neuro/conditioninfo/Pages/parts.aspx
