physiology 9

exam 9

Bipolar neurons primary sensory neuron, present in most special sensory pathways.
Bipolar neurons are located where all are in the head.
where are cell bodies for bipolar neurons located: taste, hearing, vestibular function peripheral ganglion. w/in head structures
where are cell bodies for bipolar neurons located: vision retina. no ganglion
primary sensory neuron if a sense organ is present, the bipolar neuron the cell body contacts
pseudo-unipolar neuron most common peripheral primary sensory neuron. one axon that bifurcates
pseudo-unipolar neuron cell bodies found in dorsal root (spinal) ganglion. sensory ganglia of some cranial nerves
pseudo-unipolar neuron functions proprioception, touch, pain, temp, pressure, chemical irritants
the cerebral cortex receives and processes most somatic senses. plans and initiates conscious voluntary movements
basal nuclei location deep w/in the cerebral hemispheres and close to midline.
basal nuclei has many connections with what UMN centers.
basal nuclei function orchestrate and assemble more complex motor tasks
pyramidal tracts corticospinal tracts
extrapyramidal tracts all motor tracts from brain to SC. sensing what you aren't aware of but body is
diencephalon is composed of what brain regions thalamus and hypothalamus
diencephalon rostral brainstem
medulla contain reflex centers
pons contains what cranial nerves V, VI, VII, VIII
Midbrain certain cranial nerve reflexes
cerebellum grey matter receives and processes proprioceptive, motor, and vestibular signals.
the cerebellum outputs to where UMN centers
cerebellum coordinates movements, adjusts tone, and helps maintain balance
grey matter interneurons and motor neurons
white matter three funiculi. traxts-axon bundles
funiculi contain ascending sensory and descending UMN tracts
chemical synapses NT or "Ligand" released by "pre-synaptic" cell. unidirectional.
ionotropic receptors directly induces the opening of an ion channel that is associated w/ that receptor
Metabotropic receptors NT binds a receptor that is coupled w/ a protein
Acetylcholine PNS. excitatory. Neuromuscular junction. Autonomic ganglia.
Glutamate CNS. excitatory. AMPA receptor dominates. NMDA receptor secondary
Glycine CNS. inhibitory
GABA CNS. inhibitory
Norepinephrine a1 receptor increased contraction of smooth muscle.
Norepinephrine a2 receptor decrease NE release pre-synaptically in both CNS and PNS.
Norepinephrine B1 and B2 receptor increase cAMP mediated IC events. either excitatory or inhibitory
NT categories 1.Acetylcholine 2.Biogenic amines 3.amino acids 4.neuropeptides

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.
