dendrites
A branched fiber that extends outward from the main cell body and carries information into the neuron. axon In a nerve cell, an extended fiber that conducts information from the soma to the terminal buttons. Information travels along the axon in the form of an electric charge called the action potential. terminal buttons
Tiny bulblike structures at the end of the axon, which contain neurotransmitters that carry the neuron's message into the synapse.
action potential vs. resting potential action potential
The nerve impulse caused by a charge in the electrical charge across the cell membrane of the axon. When the neuron "fires", this charge …show more content…
-LOWER LEVELS OF ALL 3 NEUROTRANSMITTERS HAVE HIGHER RATES OF AGGRESSION
Endorphins
-Resemble opiate drugs in structure and effects.
-Contribute to pain relief and to some pleasurable emotions.
-Morphine- agonist
Difference with Somatic and Autonomic nervous system (Peripheral )
Somatic Nervous System
Made up of nerves that connect to voluntary skeletal muscles and to sensory receptors.
-Consists of neurons that communicate between the body and the brain
Peripheral Nervous System
Made up of all those nerves that lie outside the brain and spinal cord.
Difference between afferent and efferent neurons (Somatic Nervous System)
Efferent Neurons
-Motor neurons
-Neurons that carry messages from the spinal cord or brain to muscles and glands
Afferent Nerve Fibers
-Neurons that carry messages from sense organs to spinal cord
-Sensory neurons
Difference between sympathetic and parasympathetic system (Autonomic Nervous System)
Parasympathetic Decision
Branch of the Autonomic nervous system that conserve bodily resources.
Sympathetic Division
Branch of the Autonomic nervous system that mobilizes the body's resources for
