Q

EPITHELIAL TISSUE EASY TO FIND BECAUSE…

A
  • Cells are closely packed
  • Cells are attached to a basement membrane
  • Located at surfaces (skin), Cavities, Glands, Veins and Bladder
  • Avascular (Dont have a direct blood supply)
  • Connected by junctions

Q

JUNCTIONS

4 TYPES

A

Tight - Prevent liquid from flowing between cells
Gap - Transport Ions between cells

Desmosomes - Attach cells side by side for strength Hemidesmosomes - Keep cells attached to the basement membrane

Q

EPITHELIAL CLASSIFICATION

A

Simple E. - Only a single layer of cells. Common where secretion and absorption take place

Stratified E. - Multiple layers of cells ares exposed to Mechanical or Chemical damage (Your mouth, nose, Ear) Exposed to outside

Q

LAYER + SHAPE

SIMPLE

A

Simple Squamous - Found in the lining of cavities, blood vessels, and lung air sacs

Simple Cuboidal - Found in the glands very good at secreting things

Simple Columnar - Found in stomach and intestines
Good protection, Secretion and Absorbing

Q

LAYER + SHAPE

STRATIFIED

A

Stratified Squamous - Surface of the skin, lining of the mouth, throat, anus, vagina. Provides protection to high damage areas

Pseudostratified Ciliated Columnar - Lungs, mostly Bronchi (Air Passages) Moves mucus and dust out of Bronchi and Trachea

Transitional - Found in Bladder, Very stretchy (Allows bladder to fill w/ liquid)

Q

GLANDS

2 MAJOR PARTS

A

Glands are made of simple Cuboidal Epithelial cells and they secrete substances

Exocrine - Surface of body

Endocrine - Surface of blood

Q

3 TYPES OF EXOCRINE GLANDS

A

Merocrine - Cell stays normal and they secrete outside of them (SWEAT GLANDS)

Holocrine - Where cell dissolves and secretes onto your skin (SEBACEOUS GLANDS)

Apocrine - Top of cell dissolves and secretes out (MAMMARY GLANDS/BREAST)

Q

CONNECTIVE TISSUE PROPER

3 FIBERS

A

Collage - Makes them strong

Elastic - Makes them stretchy

Reticular - Makes nets/mesh work structures

17
Q

CONNECTIVE TISSUE PROPER

TYPES

A

Loose

Dense (Regular and Irregular
/ \
Tendons = muscle to bone) (Ligaments = bone to bone)

18
Q

LOSE TISSUES

3 TYPES

A

Aresolar - Cushions beneath the skin and organs

Adipose - Cushioning and energy storage (Fat tissue)

Reticular - Makes up around spleen and live (Supports)

19
Q

FLUID CONNECTIVE TISSUE

2 TYPES

A

Blood

Lymph

20
Q

SUPPORTING CONNECTIVE TISSUE

2 TYPES + CELLS

A

Cartilage - Chondrocytes

Bone - Osteocytes

21
Q

CARTILAGE

3 TYPES

A

Fibrocartilage - Discs between vertebral, Menisci (Knee Pads), Pubic symphysis

Hyaline - Located in tips of bones, Trachea and Bronchi

22
Q

MEMBRANES

A

Are protecting linings and may secrete

Are formed by combining Epithelial and Connective Tissue

23
Q

4 TYPES OF MEMBRANES

A

Mucous - (Secrete Mucus)(Find in openings of body)
Serous - (Linings of cavities)(Reduce friction between cavity walls and organs. Protection from damage)
Cutaneous - (Skin)
Synovial - (Found in Joints, Fluids that help them move better)

24
Q

INFLAMMATION

A

When tissue get injured they go through inflammation

25
Q

4 STAGES OF INFLAMMATION

A
  • Swelling
  • Heat
  • Redness
  • Pain
26
Q

2 OUTCOMES W/ INFLAMMATION

A

Regeneration (Fix)

Fibrosis (SCAR)

27
Q

NECROSIS

A

Tissue destruction from cells being injured or killed

28
Q

MUSCLE TISSUE

3 TYPES & CELL NAME

A

Specialized in contraction, helps things move

Skeletal (Skeleton Move)(Striated and Voluntary)
Cardiac (Heart Move)(Striated, Involuntary & Gap Junction)
Smooth (Organs Move)(Non-Striated & Involuntary)

Myocytes

29
Q

NEUTRAL (NERVOUS) TISSUE

2 TYPES OF CELLS

A

Specializes in spreading electrical impulses throughout your body

Neurons - Transmits action potentials

Neuroglia - Support neurons help and protect

30
Q

DIAGRAM OF NEURON

A

Consists of a body and a Axon (Tail)

Sticking off the body is Dendrites (signals are received)
