Anatomy Review 1, 2, 4, 5, 9 (still study 6, 8 and 12)

Peritoneum

a large, continuous serous membrane that lines the abdominal cavity and covers most of the internal abdominal organs

Visceral

covers the organ

Parietal

covers the surrounding wall of the organ, When this overlaps, it forms the mesentery which 1.Holds the organ, 2. Holds blood supply and 3. Provides lubrication

Greater omentum

greasy apron, wall of fat

Homeostasis balances

deals with interstitial fluid

Necrosis

Triggers inflammation, cells grow and become leaky

Apoptosis

slowly starts shrinking

Ectoderm

epidermis, nervous tissue and sense organs

Mesoderm

Dermis, muscle + connective tissue, most organs

Endoderm

Epithelial linings of tracts, liver, pancreas, thyroid glands

tight junction

runs all the way around the circumference of a cell near its apical surface; seals off the intercellular space from the lumen

gap junction

forms an intercellular passageway directly from one cell's cytoplasm to the neighboring cell's cytoplasm; allows small solutes to be shared by neighboring cells

Desmosome

localized to a small location, analogous to a rivet; holds cells together; does not run around the circumference of a cell

Hemidesmosome

half of a desmosome -one side against the basement membrane

Adhering junction

runs around the circumference of a cell near its apical surface; does not tightly connect two neighboring cells together; allows intercellular fluid movement

Junctional complex

Tight + adhering + desmosome

Lamnia propia

connective tissue layer that the basement membrane sits on

Location of mucous membrane

Nasal, oral, respiratory,

Location of serous membrane

lining closed ventral body cavities

Location of cutaneous membrane

skin

Location of synovial membrane

joints

What is Epiblast

where all three germ layers go through, primary layer that gives rise to entire body

What does keratin form

intermediate fibers

Where does the plasma membrane thicken

Stratum Granulosum

Which layer of the epidermis is the thickest living layer

Stratum spinosum

What layer does keratinization begin in

Stratum Granulosum

Which dermal layer contains collagen fibers

reticular, made up of dense irregular

Steps of epidermal healing

Steps of the healing system

1. Bleeding occurs 2

2. . Blot clot form and leukocytes clean the wound

3. Granulation occurs to form granulation tissue

4. Fibrosis occurs, epithelium regenerates and scar tissue is made

What does the stratum basale contain

Keratinocytes + melanocytes

Stratum spinosum

several layers of keratinocytes, containing a network of intermediate filaments, thickest living part

Statum granulosm

Plasma membrane thickens, keratinization begins here

Epidermal derivatives

Glands, Hair, Nails

Aprocrine gland

Pinching off apical tip

Sabatous gland

Exocytosis, Holocrine gland

Mecrocrine gland

Exocytosis

Synarthroitic

immovable

Diarthrotic

freely movable

Amphiarthrotic

slightly moveable
