PSYC 1001 Lecture Notes - Lecture 3: Peripheral Nervous System, Central Nervous System, Cerebrospinal Fluid
Document Summary
Neurons (nerve cells) cells that receive and transmit electrical signals. The brain is a network of neurons. 100 billion neurons with 100 trillion connections. The brain is able to engage in complex functions because the nerve cells are organized into modules that work together. The ability to communicate from one nerve cell to another. The brain is a giant interconnected web of nerve cells. Were able to have emotions and memory because the simplistic nerve cells work in modules, in sequence together. The cns is composed of the brain & the spinal cord. The meninges (pronounced men in gees ) a three-layered membrane encasing the brain and spinal cord. The cerebrospinal fluid (csf) the colourless fluid that surrounds the brain and the spinal cord. ^ these are like an airbag in a car, the purpose of them is to protect if you were to get a blow to the head.
