he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals

NERVOUS SYSTEM The nervous system consists of the brain‚ spinal cord‚ sensory organs‚ and all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

Neurons and nervous systems Communication around the body Neurons - the basic building blocks of the nervous system‚ soecialised to communicate info around the body Three different types of neurons sensory neurons (afferent) : transfer info from the body to the brain Motor neurons (efferent) : transmit info from brain to the body Interneurins : communication b/w sensory and motor neurons Structure communication with a neuron Communication within neurons is an electrochemical process

NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

Skiing Adventure Allison Fickey ENG 101 Instructor Everett Reed 1 February 2014 The memory of Allison’s first Ski Trip to Snowshoe with her boyfriend‚ Dillon and his family still remained some of her best memories. Preparing their ski equipment seemed just like trying to get a very hyper ADD child to focus. The weather had already picked up‚ and it was hard to pull through the already freezing mess. But the time they spent skiing on the cold mountain slopes

-We have 2 parts in our nervous system: The central nervous system (CNS) is the nerves in our brain and spinal chord. The peripheral nervous system (PNS) is a network of nerve cells in the rest of our body. -Our nervous system detects stimuli and allows us to react to them. -Stimulus: a change‚ action or occurrence in the environment that can cause an organism to respond. Eg. Light‚ noise‚ pressure… How do we detect stimuli? -We have sensory organs that detect particular stimuli eg. Skin What

The protective sheaths around the brain & the spinal cord The meninges consist of three layers: the dura mater‚ the arachnoid mater‚ and the pia mater. The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. Layers of Meninges Dura Mater – means hard mother‚ the outermost w/c is tough & flexible. It surrounds & supports the large venous channels carrying blood from the brain toward the heart. Arachnoid membrane – the middle layer‚ so named because
