origin of PSNS in CNS Cranium, sacral spinal cord
origin of SNS in CNS Thoracic, lumbar spinal cord
organs with only SNS innervation sweat glands, arterioles
PSNS in heart SA node, AV node
SNS in heart SA node, AV node, myocardium
PSNS neural pathway cr nerves, sacral nerves
SNS neural pathway spinal nerves to ganglia, then splanchnic nerves to viscera
PSNS and SNS NT pre ACh and N2
PSNS NT post Ach and M
SNS NT post Norepi and a,B adrenergic
location of PSNS ganglia near or in innervated organs
location of SNS ganglia paravertebral chain g. mesenteric g.
CNS reg of ANS UMN signals from brainstem control centers monitor, modify ANS LMN
Effects of PSNS stim on SA node of heart protein phos, open K channel (GIRK). Hyperpolar cell
effects of SNS on heart cAMP mediated activation of protein kinases w/tissue actions, increase IC Ca
Tapetum is located in what type of animal scotopic animals
function of tapetum increase photon reception in very low light conditions.
why vet sp. see better in dim light 1. increase # rods 2. increase rod/cone ration 3.have tapetum
what cone types do dogs have B, Y
Graded release of Glutamate gradual increase in glutamate release w/ progressively darker conditions, gradual decrease in release w/ progressively brighter condition.
how can a hyper photoreceptor cell result in downstream activation of a bipolar cell bipolar cells have metabotropic GPCR. hyperpolar in response to glutamate. reduction of glutamate release by receptor 'disinhibits' bipolar cell and it is activated.
ionotropic GLU receptors stimulatory
metabotropic GLU receptors inhbitiory
on center produce response to light
off center produce response to dark
what characteristic of photoreceptor cells allows resolution of small changes in light intensity in a visual image convergence of multiple rods to single bipolar output. graded response of glutamate NT release
why do vet sp. fields of view differ from humans orbit orientation and dev of lateral vs medial fields of reception
what field of vision predominates in domestic animals medial retinal field (lateral vision)
where do g. cell axons first synapse: vision lateral geniculate nucleus
where do g. cell axons first synapse: PLR Pretectal nucleus
what layer is b/w the retinal layer and sclera pigmented layer
what causes "red eye" in pictures presence of pigmented layer in human. presence of tapetum w/ no pigmented layer in dog
how is the vestibulospinal tract stim vestibular nuclei facilitate LMN to ispilateral extensors
how does the vestibulospinal tract stim LMN ipsilateral extensors, inhibits ispilateral flexor and contralateral extensor
what sense organ is stim by tilting the head to one side while standing macula of saccule and utricle
what sense organ is stim by forward acceleration macula of saccule and utricle
what senes organ is stim by head turning or rotation to one side christa ampullaris of semicircular canals
why is "endolymph flow" in the semicircular canals relative inertia of the endolymph while bony cranium and semicircle canals are moving
where is the crista ampullaris located and what are the components one per semicircle canal located at one end of each of the canals
how are hair cells stim deformation of stereocilia open K channels (or close them depending on direction), depolar release glutamate, stim 1st order neuron
where is the macula and what are the components detector of static position. hair cells attach to basement mem, sterocilia embedded in gelatinous otolithic mem
what vestibular nucleus has connection w/ CN III, IV, VI Medial vestibular nucleus
function of CN III and CN VI when head moving keep eyes on target via Medial rectus and lateral rectus m. respectively.
function of CN IV when head moving keeps head oriented to target
clinical signs if dog has right vestibular lesion Nystagmus w/ slow portion toward head. head tilt toward lesion. circlin/ falling toward lesion side
what lobes of the verebellum receive and send vestibular signals to and from vestibular nuclei Flocculonodular lobes
what g. contains first order vestibular neurons for the vestibular system? location? vestibular g, adjacent to semicircular canals
components of vestibular portion of inner ear 1. bony labyrinth 2.membranous labyrinth 3.utricle 4.saccule 5.christa ampullaris 6.macula
components of ampullaris hair cells, cupula
components of macula hair cells, otoliths in gelatinous mem
components of auditory portion of inner ear 1.bony cochela-scala vestibule 2.scala tympani 3.membranous cochlear duct-vestibular mem 4.basilar mem 5.oval window 6.round window 7.hair cells 8.tectorial mem
similarities b/w peripheral auditory system and peripheral vestibular sysmtem both use hair cells and detect motion or sound by deformation of stereocilia
pathway of resonance 1.ear drum 2.malleus, incus, stapes 3.oval window 4.perilymph 5.vestibular mem 6.endolymph 7.tectoral mem 8.basilar mem
where are high frequencies detected along the cochlea proximal to oval window
where are low frequencies detected along the cochela towards helicotrema (apical portion)
what g. contains first order cochlear neurons for auditory system spiral g
where is the second order neuron for the auditory system cochlear nuclei, olivary nuclei of brainstem
where are most of the auditory relay nuclei for the auditory system spiral g, brainstem
creation of "odor map" 1. multiple different receptor types (1st order) 2.collect at individual mitral cells (2nd order)
mitral cells 2nd order olfactory neuron
how is transmission of olfactory signals to the cerebral cortex different from that of other somatic ad special sense bypass thalamus
where is the primary olfactory cortex piriform cotex
what taste sensations utilize ionotropic receptors sour, salty
what taste sensations utilize metabotropic receptors bitter, sweet, umami
where are the second order neurons for taste solitary nucleus of medulla
what makes up the choroid plexus modified ependymal (epi) cells. create ultafiltrate which is CSF
What are the primary components of CSF Water, Na, Cl, HCO3, K, CO2, O2, vit, select lg molecules.
how is CSF formed osmotic diffusion (water+electrolytes) and active transport of select lg molecules.
how does CSF exit the CNS Subarachnoid villi in dorsal sagittal sinus
primary functions of CSF mechanical protection, maintain appropriate chem balance for CNS
What makes up the blood brain barrier capillary endothelium and foot processes of astrocytes.
