holes that go down through layer of skin
transititonal epithelium
bladder, ureters
Stratified squampus non keratinized epithelium

Trachea - CT below basement membrane,
Brush border
Trachea - cilia on the columnar cells
Simple tubular gland cells
Skin - those holes for sweat gland
Simple acinar gland cells
Scalp - attached to hair follicles, big
Comound tubuloacinar
submandibular gland - Mucus is the clear one - serous is the pinker one. Pancreas - Islets, lighter stained area
Compound acinar
Mammary glands - not the ducts, circular
Dense regular connective tissue
Tendon - parallel collagen with fibroblast in row.
Dense irregular CT
skin, skalp- betweens hairs, scalp is best.
Dense irregular CT fibroblast
scalp - tiny almond shaped nucleus
Areolar tissue (Loose ct)
Skin - wispy threads between adipose or around sweat glands, go for fat
Adipose tissue
skin - big empty cells
Elastic
Artery slide - the rickrack.
Hyaline cartilage
Trachea - stained glass
Isogenous group
Trachea - chondrocytes in group
Chondrocyte in lacunae
Trachea - lacunae is clear part, chondrocyte is dark
Perichondrium
Trachea - darker stained cartilage on the edges
Chondroblasts
Trachea - would be just medial to the perichondrium, in chondrogenic layer
chondrogenic layer
Trachea- just medial to perichondrium
Elastic cartilage
Ear or epiglottis - disorderly, lots of dark stained squiqqlty bits
fibrocartilage
Interveterbral disk - Peacock feathers - fibers are more parallel. Less floaties than elastic, but more than hyaline
compact bone
ground bone
Halversian canal
Ground bone - big hole in middle
Interstitial lamellae
Ground bone - where the separate circles meet in triangle
volkesman canal
Ground bone -from one halversian canal to other
canaliculi
Ground bone - the spokes or cracks that radiate outward
Lamellae
Ground bone - rings around the halversian canal
lacuna
Ground bone - black speck
Circumferential lamellae
ground bone -
Periosteum
Developing bone - dark line outside the bright pink bone collar
endosteum
Developing bone - inner surface cells of the dark pink collar
osteoblasts
Developing bone - speacks in the outer layer of the while inner marrow islands
Osteocytes
Developing bone - embedded in the dark red matrix, collar
diaphysis
Developing bone - shaft
Compact bone developing
Developing bone - dark read collar
marrow cavity
developing bone - white open spaces inside
Epiphysis
developing bone - the cartilage bubbles
Erythrocytes
RBC - blood slide or in other arterys or veins 7-9
neutrophil
Blood - commone, multi lobed pale 10-15
esinophil
Blood - unconnon, looks like pink lungs 12-15
basophil
Blood - rare , supper dark with granules. 10-15
lymphocytes
Blood - common , nucleus is supper dark and takes up all the space
Monocytes
Blood - uncommon, horeshoe shapped - biggest
Platelet
Blood - makes small speks
Ventral horn
Spinal cord - rounded end
Motor neurons
Spinal cord, ventral horn - bigger more distinct cells
Motor neuron axons
spinal cord, don?t have nissl substance
nissl substance
Spinal cord, motor neuron - grainy part of cytoplasm
dorsal horn
Spinal cord, pointy horn -
central canal
Spinal cord - in the middle
Ependymal cells of spinal cord
Spinal cord, linning central canal
dorsal root ganglion
Spinal cord - not every slide, white matter outside cord
pia matter
Spinal cord, between the halves - direclty touching cord
arachnoid matter
Spinal cord, between halves, the fiberous part, outside pia matter
pyramidal cells
Cerebral cortex - they are in gray matter pointing to surface
molecular layer
Cerebellar cortex - grey outermost layer
Purkinje layer
cerebellar cortex - grey middle layer between molecular and granular layer
Granular layer
cerebellar cortex - grey innermost layer, below purkinje
Fasicle
Nerve slide - bundle of axons surrounded by perineurium
mylenate process
Nerve slide, longitudinal- mylein has endoneureum on it
node of ranvier
Nerve slide, longitudinal
ganglion plexus
Jejunum or stomach, large area of the lighter stained bubbly looking
myofibrile
skeletal muscle - tiniest visible strand of muscle, make up muscle fiber
striations
skeletal muscle - stripes
endomycium
skeletal muscle - around the muscle fibers which are bundles of myofibrile
