Histology - Exam 2 Assorted Images Flashcards
Caveolae of smooth muscle cell
Hemidesmosomes
Smooth Muscle Fiber Cell - with dense bodies labeled DB and corckscrew nucleus
Red arrows - Ependymal cells (glial cell) line central canal of spinal cord apical surfaces has cilia.
Autonomic Ganglia - Blue arrow - sattelite cell
Desmosome (Macula adherens)
Red arrows-Pyramidal cells. Note processes (less extensive than Purkinje cells), cell body tends to have pyramidal appearance.
Peripheral Nerve
Autonomic ganglia - Peripheral nervous system. Differ from spinal ganglia by having multipolar neurons with dendrites.
Blue Arrows point to PNS Schwann Cells
TIght Junction (zona occludens)
choroid epithelial cell - neuroglia - red arrows indicate RBCs
Dorsal Root Ganglion (large pseudounipolar neurons - look for tightly packed neurons with lots of satellite cells)
Myoepthelial Cells - unlabeled arrow points to them
Purkinje cells (cerebellum) Red arrows -cell bodies (see large dendritic trunk with branches-tree) Blue arrows - axons of the Purkinje cells
Skeletal Muscle - Black Arrows are A Bands (dark staining) BLue arrows are Z lines within A bands
Glial cell (support of nervous system) Red arrows-astrocytes (see fine processes from cell body)
Carcinoma
Multipolar motor neuron in spinal cord. Yellow arrows - dendrites (basophilic material is Nissl substance) Green arrow - axon hillock
CNS Synapse - glutamate (+) GABA (-)
Adenoma
ependymal cells
Gap Junctions, No CAMs, cells connected via Connexion proteins, regulated opening and closing
top to bottom - zona occuludens, zona adherens, and macula adherens (desmosome)
Tight Junction (Zonula occludens, occluding junction) - No CAMS, cells connected by transmembrane proteins. ONce formed, functional polarity established.
Basement Membrane
PNS Sensory ganglia - red arrow points to capsule
