Q

Simple cuboidal epithelium

A

Secretion and absorption

Ovary surface

Look: circle cells, circle nuclei, circles inside of circles (square cells)

1
Q

Simple squamous epithelium

A

Secretes lubricating substances in serosae

Air sacs of lungs

Look: big cells, thin, light, fried egg

2
Q

Simple columnar epithelium

A

Secretion of mucus, enzymes, and other substances

Lines digestive tract, gallbladder, and excretory ducts of some glands

Look: nuclei on one side of rectangle cell

3
Q

Stratified squamous epithelium

A

Protects underlying tissues in areas subject to abrasion

Epidermis of the skin

Look: just like the photo

4
Q

Areolar connective tissue

A

Wraps and cushions organs

Surrounds capillaries

Look: lines everywhere

Elastic fibers (dark thin lines), collagen fibers (thick light red lines), fibroblasts (nuclei)

5
Q

Adipose tissue

A

Supports and protects organs

Around kidneys and eyeballs

Look: big bubbles, faintly died

6
Q

Reticular connective tissue

A

Form a soft internal skeleton (stroma) that supports other cell types, including white blood cells, mast cells, and macrophages

Lymph nodes, bone marrow, spleen

Look: dark purple, big dark lines

Mast cells (looks like the real cells), reticular fibers (dark thick fibers)

7
Q

Dense regular connective tissue

A

Attaches muscles to bones or bones to bones

Tendons, ligaments

Look: light pink parallel lines, fibroblasts look like dark hyphens

8
Q

Hyaline cartilage

A

Supports and reinforces

Cartilage of the nose, trachea, and larynx

Look: cells floating alone, lighter slide, eyeballs in grape jelly

Chondrocyte in lacunae (eye ball is lacunae, center is chondrocyte)

9
Q

Elastic cartilage

A

Maintains the shape of a structure while allowing great flexibility

Outer ear

Look: hairy eyeballs in grape jelly (hair looks like scribbles)

Elastic fibers (the scribbles or hair), chondrocyte in lacuna (white part of the eyeball)

10
Q

Bone

A

Supports and protects

Bones

Look: brown, tree rings

Central/haversian canal (large central black or white circle), lamellae (rings around the canal), canaliculi (faint squiggly lines that connect one ring to another), osteocytes in lacunae (small black dots on rings)

11
Q

Blood

A

Transport of respitory gases, nutrients, waste, and other substances

In the blood vessels

Look: red cells

Erythrocyte/rbc (pale pink dots), leukocyte/wbc (purple cells)

12
Q

Striated skeletal muscle

A

Voluntary movement

Skeletal muscles attached to bones or skin

Look: striations length wise, no discs

Nucleus (dark dots), striations

13
Q

Striated cardiac muscle

A

As it contracts it propels blood into the circulation

Walls of the heart

Look: dark blue/black

Nucleus (dots), striations, intercalated discs (measure bars)

14
Q

Smooth muscle

A

Propels substances along internal passageways

Walls of hollow organs

Look: kiwi

Nucleus (dark dot in center)

15
Q

Nervous tissue

A

Transmits electrical signals

Brain

Look: coffee stain

Neuron (big dark objects), nucleus (center of neuron), cell processes (connections of neurons), cell body (cells)
