Cerebrum

• grey matter

Cerebrum

• grey matter

Cerebellum

• layering

Choroid Plexus

• ependymal cells present

Neuron

• large, 3 Russian doll circles (nuclear body, nucleus, nucleolus)

Ganglion

• lots of cell bodies surrounded by nothing else (bundle of neurons)

Oligodendrocyte

-white sections are the myelin

Oligodendrocyte

Ependymal cells

Nerve

Nerve

linear and TONS of nuclei ( even though it might looks like dense, regular connective tissue at first... there are too many nuceli).

Astrocyte

-just cell body = just purple dots

Meninges

Appositional growth (perichondrium between connective tissue and cartilage)

Arteriole

-less than 3 fish layers/tunica media

Capillary

Capillary

Elastin/elastic artery

Endocardium

-single endothelial layer next to myocardium

Fibrocartilage

Interstitial growth

Lymphatic vessels

Osteoblast

Osteoclast

Osteoclast

Osteocytes

skeletal

-Striation, long parallel fibers, peripheral nucleus

Skeletal

-Round fibers with peripheral nuclei

Dense, irregular connective tissue

-Nuclei sparse, tons of cytoplasm, random arrangement

Cardiac

-branching with central nucleus

Dense, irregular connective tissue

-Nuclei sparse, tons of cytoplasm, random arrangement

Brown adipose

-small lipid droplets

White adipose

-Looks like bubble wrap, one large lipid droplet, peripheral nucleus

Elastin

Elastin

Recticulin

-Mesh work of thin fibers

Recticulin

Loose connective tissue

-Whirl-like fibers, lots of white space

Dense Regular Connective Tissue

-mermaid hair -linear fibers with oval peripheral nuclei

Dense, irregular connective tissue

-Sparse nuclei, lots of cytoplasm, random whirl-like appearance

smooth muscle

-TONS of Oval nuclei, no striation

• you can tell cardiac and smooth apart because even though they both have central nuclei, smooth muscle will have a lot more nuclei

Smooth muscle

Tightly packed nuclei

Smooth muscle

-Parallel oval nuclei, lots of nuclei, no striation

Cardiac muscle

-Striation, branching

Cardiac muscle

-Branching, striation, central nucleus, intercalated disc on longitudinal section

Nucleus of Fibroblast (fibroblasts are found in connective tissue)

What is the arrow pointing at and what is the cell type?

Collagen fibers within dense, irregular connective tissue

Dense, irregular connective tissue

Dense Regular Connective Tissue

-Dont mind the black/white (look at pattern)

Loose connective tissue

Cardiac muscle

-intercalated discs present

Brown adipose

White adipose

White and Brown adipose

Dense, regular connective tissue

Smooth muscle

-both cross and longitudinal due to tubular organ

Cardiac muscle

Fibroblasts

-within connective tissue

What cell is the arrow pointing at?

Skeletal muscle

Vein and artery

What two structures are present?

Woven Bone (cartilage)

Lamellar Bone (cartilage)

Endochondrial Ossification

Joint

-collagen connective tissue between two bones

Outside= compact Inside= cancellous

What are the outside and inside layers?

Woven Bone (cartilage)

Lamellar Bone (cartilage)

synovial joint

-white is synovial fluid -cells lining are synoviocytes
