Nervous System
Central Nervous System (CNS) - The brain and spinal cord
Peripheral Nervous System (PNS) - The nerves connecting tissues to CNS, Impulse relay.
Neurons and Neuralgia make up nervous tissue.
Neurons transmit impulses
Neuralgia support neurons
Neuron Body
Neurons- Nervous system cells that transmit impulses between one and other.
Axon- Conducts nerve impulses within Myelin Sheath, or nerve fiber. Dendrites- Extensions connecting to other cells, either neurons or tissue cells. Send signals between CNS and tissues.
Types of Neurons
Sensory Neurons- Relay impulses from sensory receptor to the CNS.
Motor Neurons- Relay impulses away from CNS to tissues or glands creating a response.
Impulses
Action Potential- Na and K pump change in polarity across an axonal membrane as the nerve impulse occurs, in an "all or none" manner.
Resting Potential- the Axon is not using Na and K pump to conducting an impulse. The inside of the neuron is more negative (polarity) than the outside of the neuron.
Synapse- the Dendrite terminal or cell body of a neuron conducts at this point. This point of communication between the two neurons uses neurotransmitters that are stored in the synaptic vesicles.
CNS
Spinal cord- Center of spinal column and serves as a "highway" for all communications.
Brain- Computes impulses and determines the response send back information for response.
PNS
Somatic system- Skin tissue, skeletal tissue, and tendons that receive information from an external sensory receptor. The information is transmitted to the CNS.
Autonomic system- Automatically controls cardiac, smooth muscles, and glands. The sympathetic and parasympathetic nervous system
Sensation Response
Sensory receptors respond to our environment
Sensory receptor cells trigger action potential
Using taste, smell, vision, hearing, and equilibrium sensory receptors transmit impulses to CNS.
