test 1: lab 4 Flashcards
Two major ascending tracts in the brain stem, the medial lemniscus which is ___ and spinothalamic which is ___
touch and pressure
pain and temperature
__ regulates cardiovascular system control , respiratory control, pain sensitivity control, alertness, awareness, and consciousness.
reticular formation (in the brain stem)
medulla begins after the __ and includes the __
pons
trapezoid bodies
the midbrain is between the ___ and the pons
mammillary bodies
vagal area
vestibular area
deep to this is the vestibular nuclei
area postrema
(no blood brain barrier → CVO)
reticular formation → arousal, respiratory, cardiac, vasomotor, gastric network
what is the red?
somatic sensory to trigeminal CN5
green?
CN 8 vestibular cochlear
sensory for hearing/balance
blue?
sensory for taste and baroreceptors
nucleus( tractus) solitarius
where is CN3 nuceli
oculomotor → somatic motor
CN 4
somatic motor to trochlear
Trigeminal motor
CN5
motor to branchiomotor
CN 6
abducent
somatic motor
CN 10
parasympathetic (motor) to dorsal motor of vagus
12?
hypoglossal
somatic motor
CN7
motor branchiomotor
facial
where do you find motor nuceli in the medulla
in the medulla cause you can see the 4th ventricle
motor = medial
sensory= lateral
solitary nucelus
green
top= gustatory nucleus (SVA) → CN 7,9,10
bottom= cardiorespiratory nucelus (GVA) → CN 9, 10
found in the medulla
the cardiorespiratory nucleus of the ___ nucleus contains __
solitary nucleus
VA from carotid sinus (BP), and carotid body (blood pH, pCO2, pO2)
green
where do you find special motor to branchial area?
pink
- motor trigeminal nucleus (SVE)
- motor facial nucleus (SVE)
- nucleus ambiguus (SVA)
vestibular nuceli
special sensory afferents
cochlear nuclei
Special sensory afferent
afferent to trigeminal
general somatic afferent
mesencephalic
main sensory
spinal trigeminal
where do you find special efferents in the medulla?
nucleus ambiguus (SVE)
green
solitary nucleus
special afferent
taste rostrally, cardiovascular center caudally
