Transcript of Neurons

What is a neuron? A neuron is a sepcialized cell that stores information and carries messages within the nervous system and between other body system. What are the parts of a neuron? A neuron contains seven body parts which are, a nucleus, axon, dendrites,myelin sheath, node of ranvier, and shwann cells. This following picture will demonstrate where the body parts are located more precisley. How do neurons transfer messages from one to another? Neural messages are transmitted from one neuron to another by the use of chemicals known as neurotransmitters. There are 2 classes, excitatory and inhibitory. These chemicals are released from the end of one nerve cell, interact with specific receptors. How do neurons transfer messages to skeletal muscles. Neurons tranfer messages to skeletal muscles by
using neurotransmitters, it also uses a motor neuron
to a skeletal muscles which require neurotransmitters
known as acetylcholine

How are neurons in the peripheral
and central nervous systems connected together? The peripheral nervous system, or PNS, consists of the nerves and ganglia outside of the brain and spinal cord. The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs. (The following picture will display the
Peripheral nervous system, and the
second will demonstrate the central
nervous system) THE END !
