what are the four parts of the central regulation ?
- visceral control
- somatic sensory
- sympathetic efferent
- efferent to skeletal muscles
the visceral controls what? and has what three structures?
the brainstem
- hyopthalamus
- thalamus
- limbic
what happens when efferent signals go the muscles?
SPLINTING
- somatic reflex causes overlying muscle to contract -trys to build a wall to protect the system
what happens to the somatic sensory areas?
sends signals to the corticla (conscious) sensory area likely to be interpreted as referred pain
what happens to the sympathetic efferents?
autonomic reflex shuts down inflammed visceral organs
where is the pre ganglionic located?
in the spinal cord or brainstem
where is the post ganglionic located?
in periphery
name three differences between the somatic and autonomic system:
control (regulation)
organs fx w/o neural input
peripheral nerve pathways
control (regulation)
somatic has conscious
autonomic has non conscious
organs fx w/o neural input
somatic = no autonomic = yes
peripheral nerve pathway
somatic = one autonomic = usually two (with synapse
tell me three great things about the somatic
- has conscious control
- organs cant fx w/o neural input
- has one peripheral nerve pathway
tell me three great things about the automatic system?
- has nonconscious control
2.can fx w/o neural input
3 .usually has two (with synapse) peripheral nerve pathways
your post ganglionic cell can be called a
reference point
you pre ganglionic fx
to be close together w/ cell body to create a synapse
