Question 15

Several types of fixed and
wandering cells

Answer 15

Connective Tissue

Question 16

Abundant amount of Extracellular Matrix

Answer 16

Connective tissue

Question 17

Support (underlying our epithelial tissue is our connective tissue, providing the necessary nutrients that the epithelium needed for metabolism) and protection

Answer 17

Connective Tissue

Question 18

is characterized by close cell apposition and presence at a free surface

Answer 18

Epithelium

Question 19

whether arranged in a single layer or in multiple layers, are always contiguous with one another

Answer 19

Epithelial cells

Question 20

they are usually joined by specialized cell-to-cell junctions that create a barrier between the free surface and the adjacent connective tissue

Answer 20

Epithelium

Question 21

The__________________ between epithelial cells is minimal and devoid of any structure except where junctional attachments are present

Answer 21

intercellular space

Question 22

Cell shapes include:

Answer 22

 Squamous (flattened)
 Cuboidal (almost have equal sides)
 Columnar (they are taller than they are wide)

Question 23

Layers are described:

Answer 23

 Simple (single layer)
 Stratified (multiple layers)
 Pseudostratified (stratified because iba iba ang height ng cell making their nuclei in different levels, giving an impression that they’re multiple layers but they’re only a single layer because they’re from only one base)

Question 24

three germ layers includes:

Answer 24

Ectoderm
Mesoderm
Endoderm

Question 25

is the outermost of the three
germ layers.

Answer 25

ectoderm

Question 26

major classes of ectoderm

Answer 26

– surface ectoderm
– neuroectoderm

Question 27

SURFACE ECTODERM gives rise to:

Answer 27

– epidermis and its derivatives (hair, nails, sweat glands,
– Sebaceous glands
– Parenchyma and ducts of the mammary glands),
– cornea and lens epithelia of the eye
– enamel organ and enamel of the teeth
– components of the internal ear
– adenohypophysis (anterior lobe of pituitary gland)
– mucosa of the oral cavity
– lower part of the anal canal.

Question 28

NEUROECTODERM gives rise to:

Answer 28

– the neural tube and its derivatives, including components of the central nervous system, ependyma (epithelium lining the cavities of the
brain and spinal cord), pineal body, posterior lobe of pituitary gland (neurohypophysis), and the sensory epithelium of the eye, ear, and nose;
– the neural crest and its derivatives, including components of the peripheral nervous system..

Question 29

is the middle of the three primary
germ layers of an embryo.

Answer 29

Mesoderm

Question 30

Mesoderm gives rise to:

Answer 30

– Connective tissues
– Striated muscles and smooth muscles
– Heart, blood vessels, and lymphatic vessels
– Spleen
– Kidneys and gonads
– Mesothelium
– Adrenal cortex

Question 31

is the innermost layer of the three germ layers forming the wall of the primitive gut and gives rise to epithelial portions or linings of the organs arising from the primitive gut tube in primitive embryo

Answer 31

Endoderm

Question 32

Derivatives of the endoderm include:

Answer 32

– alimentary canal epithelium
– extramural digestive gland epithelium
– lining epithelium of the urinary bladder and most of the urethra;
– respiratory system epithelium
– thyroid, parathyroid, and thymus gland epithelial components
– parenchyma of the tonsils
– lining epithelium of the tympanic cavity and auditory (Eustachian) tubes.
