NeroMam 3000 mid 1

Nerve Plexus

network of intersecting nerves

golgi staining

silver staining technique (KCrO4/AgNO3)

Immunochemistry

use of fluorescently labelled antibodies to localize protein location (direct or indirect)

Filling

Injection or axonal transport of biocytin, GFP, or neurobiotin

Oligodendrocytes

cell myelinating multiple portions of an axon or multiple axons

Astrocyte

Role in mechanical support, blood pressure regulation, and ion composition

Microglia

Immune cell, reorganize neuronal connections

RMP

-70mV

Threshold

-55 my

Peak

35 mV

NKA

Sodium potassium ATPase (3 Na out to 2 K in)

Axon Hillock

Neck of axon where AP is generated

ESPs/ISPs

Excitatory/Inhibitory post-synaptic potentials

Clear core vesicles

small NTs

Dense core vesicles

Peptides and some biogenic amines

Mechanism of release of NT

influx of Ca, binding of t- and v- snares and synaptogamin, fusion pore formation

Ionotropic receptor

NT binds to channel, causing conformational change to open or close the channel

Metabotropic receptor

Receptor uses a 2nd messenger to induce change (cAMP or cGMP)

Falx cerebri

dura mater between 2 hemispheres of cerebral cortex

Tentorium cerebelli

seperates cerebellum from brainstem

Diaphragma sellae

hole in tentorium sellae for pituitary

Innervation of dura mater

Supratentorium: trigeminal nerve

Infratentorium: cervical and spinal nerves

Arachnoid villi

One way valve into the venous sinuses

Cisterna magna

Conus medullaris

end of spinal cord

cauda equina

11 spinal nerves from L1-coccyx

Filum terminale

modification of pia mater anchoring the end of the spinal cord

Commissures

connect hemispheres

Pre-central gyrus

Frontal lobe, main motor cortex

Post central gyrus

Parietal lobe, main somatosensory cortex

Auditory cortex

on upper portion of superior gyrus of temporal lobe

Calcarine sulcus

Occipital lobe, visual cortex

Cingulate gyrus

limbic lobe around corpus callosum

3 Basal ganglia

caudate nucleus, putamen, globus pallidus

Basal ganglia

important for modulating movement and posture

Sections of internal capsule

anterior lim, posterior limb, genu, retrolentiform

Vermis

longitudinal division of cerebellum into hemispheres

Flocculonodulor

Lobe of cerebellum
