the 4 major regions of the brain
peduncles
Huge tracts that connect pons to cerebellum are Cerebellar _______
cerebral peduncles
Motor tracts on their way down from cerebrum, first time you see them are in cerebrum
Epithalamus, thalamus, hypothalamus
Parts of the Diencephalon
Secondary respiration center, sensory tracts, motor tracts, cerebellar peduncles
Pons are made of
gyrus
bulge b/w sulcus
descending toward spinal cord
in pons all motor tracts are
emotional and breathing
in the limbic system the brain stem
frontal cortex
in the limbic system the cerebrum
thalamus and hypothalamus
in the limbic system the diencephalon
Cerebral peduncles, corpora Quadrigemina
midbrain consist of
Medulla oblongata, pons, midbrain
parts of the brain stem
cardiac, primary respiratory, vasomotor, swallowing, coughing, sneezing, vomiting center
parts/ center of medulla oblongata
varoli
pons are also called
Apneustic center, Pneumotaxic center
what are the two parts of the secondary respiratory center that regulates breathing the way you want to
reproduction, growth, development, water salt balance, metabolism
what happens in the hypothalamus when the nervous system/endocrine system link
Melatunium
what hormone does the pineal gland produce
cerebral cortex
what is the outer layer of cerebrum2-3mm sulcus and gyrus
Central sulcus
what separates frontal lobe from parietal lobe
longitudinal fissure
what separates the cerebrum
basal nucleus
what are the synapses of the cerebrum motor receptors called
projection, commissural, association tracts
what are the three tract in the brain
Epithalamus
(Above) contains pineal Glands
Superior Colliculi
(Above) controls or involve in visual reflexes, skeletal muscle, signal starts here to move eyes *Somatic movement
Inferior Colliculi
(Below) controls Auditory reflexes
Cardiac center
Control center that regulated hart, parasympathic, synapses "Nucleus"
cerebrum
2 hemispheres, contains sulcus and gyrus
Ascending tracts, column white matter
All Sensory tracts located below leading for cerebrum are __________ and are located ________
Descending tracts, column white matter
All motor tracts from above leading to spinal cord are _______ and located _________
reticular formation
Consciousness, focus of attention, sensor filter
ascending toward cerebrum
In pons all sensory tracts are
olfaction pathway
Mammillary bodies are responsible for
Sneezing center
Regulates sneezing
Thalamus
Sensory relay station for synapses on the way up to cerebrum
smell senses
all senses synapses in thalamus except
corpus callosum
connecting tracts of cerebrum
Corpora Quadrigemina
consist of Superior and Inferior Colliculi
Limbic system
controls emotional response
sulcus
cracks b/w gyrus
Taxia
damage to cerebellum disease lack of motor skills/coordination
4 information sources that the cerebellum
descending motor signal, ascending sensory signal from muscles, balance signals from inner ear, visual signal from eye are
hypothalamus autonomic systems controls
detect oxygen, temperature and hunger feeling full, mammillary bodies
Brainstem, diencephalon, cerebellum, cerebrum
four region of the brain from bottom to top
parts of cerebellum
inner tissue called Arbor vitae, coordinates motor actives and balance, utilizes information fro four sources
Parts of Hypothalamus
link between nervous system and endocrine system, location for autonomic system control
somatic movements of the superior Colliculi
make eyes move/optimizes eye, focus, change lens shape and pupil shape
Pineal glands
produce hormone called Melatunium
Vasomotor center
regulated blood pressure
Swallowing center
regulated swallowing
Secondary respiratory center
regulates breathing the way you want to
Coughing center
regulates cough
Primary respiratory center
regulates normal breathing
Vomiting center
regulates vomiting
frontal, parietal, occipital, temporal and insula/center lobes
what are cerebral the lobes
brainstem, diencephalon, cerebrum
the limbic system over lapse
cerebrum, diencephalon, brainstem
the reticular formation over lapse ( top )
Association tracts
tracts in the brain that are different lobes of cerebrum to same side
Commissural tracts
tracts in the brain that are right to left ex. corpus callosum
Projection tracts
tracts in the brain that connects higher to lower ex. cerebrum to any part below thalamus
