Anatomy 5 Flashcards
Functions of the nervous system
Sense external and internal environments, integrate sensory information, coordinated involuntary and voluntary activities
Control prefor effectors
What somatic system controls is
Skeletal
Automatic nervous systems
Involuntary
Basic functions of a unit is called
Neuron
Axon parts
Axon hillock connects axon to cell body
Synapse is side of
Communications
Because lack of anturals the central nervous system the
Neurons can’t divide
Ineral receptors that monitor are
Inside
Proceral receptors position for
Joints
Bi polar
One axon one dentrite
Multi polar (most common)
One axon many dentrites
Neuron cell body of peripheral nervous system are clustered in
Ganglia
Astrocite functions
Maintain the blood-brain barrier, absorb access neuro transmitter, respond to neuro damage and form 3 deminition framework of central nervous system
Alegondeno cites
Make up mythlon seeth of central nervous system
Microgleia
Are fegocites
White matter
Mylonated
Gray matter
Unmylonated
Statilite cells
The Gleno cells in the peripheral nervous system
When electrical and chemical forces together it is
Electrical chemical radiant
Absolute fractory period
When action potential begins until another action potential is enicasted
Minimal stimulus
That triggers action potential is called threshold
Continuous propagation
Goes all entire length
Posterior root ganglia
Contains sensory neurons
31 spinal cord segments for spinal nerves they contain
Sensory and motor neurons
