Chapter2 Flashcards
Learn about the nervous system and brain
The Nervous system consists of two major systems
Central nervous system and Peripheral nervous system
The Central nervous system consists of two components
the brain and spinal cord
the peripheral nervous system consists of two major components
somatic nervous system and autonomic nervous system
The Autonomic nervous system consists of two systems
Sympathetic and Parasympathetic nervous system.
The central nervous system is..
the part of the nervous system that consists of the brain and spinal cord.
the peripheral nervous system is…
the part of the nervous system that enables nerves to connect the central nervous system with the muscles, organs, and glands.
what are the four parts of a nuron
dendrites, cell body, the axons, and the terminal buttons.
The dendrites
are the short branch like extensions. they detect signals from neighboring neurons.
in the cell body
info from other neurons is gathered and integrated.
terminal buttons
knoblike structures at the end of the axon
synapse
where communication occurs between neurons
action potential
neural impulse that travels down axon and causes release of neurotransmitters into synapse
three steps to neural communication
transmission, reception, integration
neurotransmitters
chemicals that carry information from one neuron to another
acetylcholine
motor control over muscles
