Flashcards in 022014 3 Neurohistology Deck (22):
Function and location of purkinje cells?
motor neuron in cerebellum
inhibit motor function of surrounding neurons by releasing GABA
Function and location of pyramidal cells?
motor neuron in cerebrum
excite surrounding neurons by releasing glutamate
inhibit surrounding neurons by releasing GABA
Function and location of alpha motor neurons (lower motor neurons)?
motor neuron in brainstem and spinal cord
innervate skeletal muscle fibers, aiding in contraction
Function of interneurons.
release GABA to inhibit surrounding neurons
This cell type is the largest glia, has euchromatic nucleus, no visible nucleolus, and secretes GFAP.
This cell type functions to scavenge for neurotransmitters, tell endothelial cells to form BBB, is involved in glial scar formation, secretes cytokines, and becomes reactive and increases GFAP following CNS trauma/alzheimer's.
What cell type is infected by HIV?
Grey or white matter is 80% lipid?
What cells form the brain-CSF barrier, are ciliated in order to move CSF, and originate from neural tube?
Where are sympathetic fibers located? parasympathetic?
CN 3, 7, 9, 10, S2-S4
What are the components of the choroid plexus?
The dura is similar to what connective tissue layer of the peripheral nervous system?
The arachnoid is similar to what connective tissue layer of the peripheral nervous system?
The pia is similar to what connective tissue layer of the peripheral nervous system?
The middle meningeal artery is located in what space?
The superior sagittal sinus is located in what layer?
Bridging veins are located in which space?
What space contains the CSF?
What neurotransmitter activates sweat glands?
What type of neuron is found mostly in the PNS, is sensory, has a single axon that bifurcates, and has no dendrite?
What type of neuron is usually found in the PNS, has one axon, one dendrite, and is special sensory?
