Histology Review….woooooo

Don’t kid yourself. You know you love it.

• Lymphocyte• Arrows are platelets

• Dark Red Region?• Long White Arows?• Small White Arrows?

• Hint: Skeletal Muscle• I = Iband (light)• A = Aband (dark)• N = nucleus of muscle cell• F = fibroblast

• Eosinophil

• Above?– Muscle spindle

• Two blue arrows– Intrafusal fibers

Name the types of tissues

• Neutrophil

e

• Red I band (actin)• Blue A band (myosin)• Yellow Sarcomere• M= ? mitochondria

• Little black arrows = intercalated discs

DENDRITES

AXON HILLOCK

• Smooth muscle—longitudinal section

• Monocyte

• Hint: elastic artery

• Yellow Circle? Fasicle (bundle of muscle cells)• Red Arrows? Arteries/veins supplying muscle cells

• Middle Cell = postsynaptic cell• Outer two cells = Presynaptic cells

• Basophil

• N = chondrocytes

• Red arrow= isogenous group

• Yellow arrow? Muscle fiber/cell• Red Arrow? Endomysium

• Blue = unmyelinated axon• Yellow = myelinated axon

• Monocyte

• Hint: this is very high power

• L to R: Neutrophil, Basophil, Eosinophil

• Yellow Arrow:

• M Line• Red Arrow:• Z disc

• Whole Picture B:

• Sarcomere

• NR = node of ranvier

BASALLAMINA

MYELIN

AXON

• Hint: muscular artery

• L: Basophil• R: Lymphocyte

• Pericytes around capillary

• Medium artery (MA) and vein (MV)

• Hyaline Cartilage

• P = ? Pericytes (around capillary)

• Type of tissue and layers

ENDONEURIUM

• Elastic Cartilage (stained for elastic fibers)

• Perichondrium

• Immature (woven) bone

• C = haversian canal• Red = lacunae (for osteocyte)• Green = canaliculi

• Dorsal Root ganglion

• Pseudostratified ciliated columnar epithelium

• A = Osteoclast • B = Osteocyte• C = Osteoblast• D = Osteoid• E = Trabeculus of bone

• Fibrocartilage

• Tissue Type = elastic cartilage• Arrow = elastic fiber

• Simple Squamous Epithelium

• Simple columnar epithelium

Simple columnar epithelium

• Yellow = goblet cell• Red = basement membrane

• Arrows = basement membrane

• RC = zone of reserve cartilage• P = zone of proliferation• H = zone of hypertrophy• C = zone of calcification• B = zone of bone deposition (and cartilage removal)

• Reticular Connective Tissue

• Simple squamous epithelium (protruding nucleus)

• Stratified columnar epithelium

• Simple cuboidal epithelium

• Dense irregular connective tissue

• Arrow = cilia

• Nonkeratinized stratified squamous epithelium

• Elastic cartilage (H&E)• Yellow = chondrocyte• Black = elastic fibers

• Transitional epithelium

DORSAL ROOT GANGLION:NEURON SATELLITE CELL FIBROBLAST

• Loose connective tissue• Red = macrophage• Green = blood vessel• Yellow = fibroblast• Purple = collagen fiber

• Adipocytes

• Tissue type?• White adipose tissue

• Dense regular connective tissue (tendon)

• Fibrocartilage• Chondrocyte

• Plasma Cells (note clock face nuclei)

• Tissue Type = Loose connective tissue• Red = collagen bundle• Black = elastic fiber

• IT = interterritorial matrix• T = territorial matrix• Red = lacunae• Yellow = chondrocyte

(

• Osteon (Haversian system)

• Sympathetic Ganglion
