1. places of exit= thorax and lumbar areas (thoracolumbar nervous system)
autonomic nervous system a. sympathetic nervous system
-
occipital lobe
involved in vistion
-
temporal lobe
involved in audition ( hearing ) and olfaction (smell)
-
parietal lobe
involved in somethesis (pain , touch, pressure, and temp) taste, and kinesthesis (limb position )
-
frontal lobe
involved in abstract thinking speech and initation of voluntary movement
-
1. diencephalon
2. telencephalon
2 parts of the Forebrain
-
thalamus
the "great relay center" of the brain. all the senses except olfaction send impules to the thalamus on the way to the cortex
-
hypothalamus
regulates the autonomic nervous system controls many basic drives (hunger and thirst)influences endocrine secretions controls the internal enviornment (body temp)
-
1. thalamus
2.hypothalamus
2 parts of the diencephalon
-
midbrain
connects the hindbrain and the forebrain
-
cerebellum-
involved in motor coordination
-
pons
connect the medulla to higher brain areas
-
medulla
pons
cerebellum
3 parts of the hindbrain
-
hindbrain
midbrain
forebrain
3 parts of the brain
-
medulla
"vital center" of the brain controls heart beat blood pressure and breathing
-
Central nervous system
spinal cord
- 1. mediates reflexes
- 2. conducts impuleses to and from the brain.
-
preganglionic fiber-
oes from the brain or spinal cord to a collateral ganglion. is relativily long secretes ACH Parasympthetic nervous system
-
postganglionic fiber
- goes from the collateral ganglion to the organ to be innervated is realitivly short, secretes ACH
- Parasympthetic nervous system
-
Parasympthetic nervous system
functions
conservation and storage of bodily resourses very active after eating
-
cranial and sacral areas (cranlosacral nervous system)
- Parasympthetic nervous system
- places of exit
-
preganglionic fiber
- goes from the spinal cord to the synamptic chain. is relatively short, secretes ACH
- autonomic nervous system a. sympathetic nervous system
-
postganglionic fibers
- goes from the sympathetic chain to an organ to be innervated is relatively short secretes ACH
- nervous system a. sympathetic nervous system
-
autonomic nervous system a. sympathetic nervous systemfunctions
mobalization of bodily resourses "fight" or "flight"
-
gyrus
mountain in hemisphere
-
sulcus or fissure
vallies in hemisphere
-
basal ganglia
involved in motor coordination (affected in parkinsons disease)
-
limbic lobe
part of the anatomical substrate for emotions
-
hippocampus
- involved in memory (transferring from short term to long term)
- destroy => memory deficits
-
Amygdala
- an excitatory structure
- destroy => tameness, docility or placidity
-
septum
- an inhibitory structure
- destroy => rage
-
reticular formation
- overlaps the forebrain, midbrain, and hindbrain
- this part of the brain alerts and arouses the cortex
- many drugs (sleeping pills and stimulants) act on this part of the body
-
cerebral hemispheres
basal ganglia
limbic lobe
hippocampus amygdala and septum
- 3 parts of the telencephalon
- 3 divisons of the 3rd one
