17
Q

Totipotent

A

Embryonic cells that can differentiate to any type of cell

18
Q

Ectoderm

A

Outer embryonic layer which the epidermis and nervous tissues derive from

19
Q

Mesoderm

A

Middle embryonic layer where connective and muscle tissues derive from

20
Q

Endoderm

A

Inner embryonic layer where most digestive and respiratory tracts derive from

21
Q

Synovial Membrane

A

Connective tissue that lines joints and tendons

22
Q

Epithelial Membrane

A

Epithelial and connective tissues attached

23
Q

Cutaneous Membrane

A

Term for skin

24
Q

What is the basement membrane?

A

Formed by basal and reticular lamina they protect tissues from mechanical stress

25
Q

Simple Squamous Epithelium

A

Thin layer that allows substances to pass through diffusion and filtration, air sacs of lungs, lining of the heart, blood vessels are examples

26
Q

Simple Cuboidal Epithelium

A

Type of epithelial cell that creates ducts and glands, secreting and absorbing

27
Q

Simple Columnar Epithelium

A

Epithelial cells that make tissues in the bronchi, uterus, and digestive tract. They absorb and secrete mucous and enzymes

28
Q

Pseudostratified Columnar Epithelium

A

Tissues that line the trachea and respiratory tract, secrete

29
Q

Stratified Squamous Epithleium

A

Lines esophagus, mouth and vagina and protects against abrasion

30
Q

Stratified Cuboidal Epithelium

A

Protective tissues that make sweat glands, salivary glands, and mammary glands

31
Q

Stratified Columnar Epithelium

A

They secrete and protect, making the male urethra and ducts of glands

32
Q

Transitional Epithelium

A

Allow for expansion of urinary organs, lines bladder and urethra

33
Q

Endothelium

A

Thin membrane that lines the inner walls of the heart and blood vessels

34
Q

Membranes that cover and protect internal organs:

A

Mesothelium

35
Q

Goblet Cell

A

Secrete mucin and create protective layers of mucus

36
Q

Endocrine Glands

A

They are ductless and secrete hormones that travel through blood

37
Q

Exocrine Glands

A

Ducts that have secretions released to the body surface, mucous, sweat, oil

38
Q

Multicellular Glands

A

Composed of a duct and secretory unit, they are supported by connective tissues and supply blood and nerve fibers

39
Q

Unicellular Glands

A

Consist of mucous and goblet cells, they are in epithelial linings of intestines and respiratory tract to lubricate with mucin

40
Q

Atrophy

A

Wasting away of a body tissue
