Question 10

Meme break

Answer 10

You got this!!

Question 11

Name the epithelia

Answer 11

stratified cuboidal (BOB)

Question 12

Name the epithelia

Answer 12

Simple columnar (CAROL)

Question 13

Name the epithelia

Answer 13

Stratified columnar (JIM)

Question 14

Name the epithelia

Answer 14

Pseudostratified (Alex)

Question 15

What is the function of simple squamous epithelia?

Answer 15

They provide a barrier that fluids and gasses can be exchanged through, and produces serous fluid.

Question 16

Where can you find simple squamous epithelia?

Answer 16

The air sacs of the lungs, inner lining of ventral body cavities and blood vessels, and certain parts of the kidney

Question 17

What epithelia is found in kidney tubules, lower respiratory passages, and many endocrine glands? (Functions include absorption and secretion)

Answer 17

Simple cuboidal epithelia

Question 18

Where are simple columnar epithelia found and what is their function?

Answer 18

Found in digestive tract, uterine tube, gallbladder and certain kidney tubules. They absorb and secrete while also propelling the egg through the uterine tube

Question 19

What epithelium is found in places that need to stretch (ex. bladder) and what does it do?

Answer 19

transitional epithelium

Question 20

Answer 20

Study through it!!

Question 21

What epithelium is found in the nasal cavity, male urethra, and upper respiratory passages, while secreting mucous and propelling it with ciliary motion? (Goblet cells)

Answer 21

Pseudostratified epithelia

Question 22

What is the difference between keratinized stratified squamous epithelia and non-keratinized?

Answer 22

Keratinized epithelia has dead cells at the apical layer, and prevents water loss through skin.

Question 23

Where is keratinized squamous epithelium found? Non-keratinized?

Answer 23

Keratinized is found in the skin (epidermis) and non-keratinized is found on the mouth, vagina, and anal canal.

Question 24

How do stratified squamous cells move upward?

Answer 24

Cuboidal or columnar cells at the bottom are pushed upward due to polarity and mitosis. As they move toward the apical layer, they lose cytoplasm and become squamous.

Question 25

Where are stratified cuboidal epithelia found?

Answer 25

The ducts of the salivary, mammary, and sweat glands

Question 26

What epithelia functions as protection while also secreting and absorbing substances?

Answer 26

Stratified columnar epithelia

Question 27

Endocrine glands produce_______, which are regulatory hormones released directly into the extracellular space.

Answer 27

Hormones

Question 28

Give an example of an endocrine gland.

Answer 28

Thyroid, pituitary, adrenal, ovary, parathyroid, testicle

Question 29

What are the different types of exocrine glands?

Answer 29

Unicellular and multicellular

Question 30

Answer 30

Me after failing even after making this long ass review

Question 31

What do unicellular exocrine glands do?

Answer 31

Secrete mucin using goblet cells

Question 32

Multicellular glands are ________ in __________.

Answer 32

covered; epithelium

Question 33

What are the major classes of connective tissue?

Answer 33

Connective tissue proper, cartilage, osseus (bone), and blood

Question 34

What makes connective tissue?

Answer 34

Extracellular matrix, vascularity (blood supply), structural elements (ground substance, extracellular fibers, and cells)

Question 35

What is the difference between the extracellular matrix and ground substance?

Answer 35

The extracellular matrix is found between cells and delivers nutrients, while ground substance is like a highway for cells to communicate and exchange waste and nutrients.

Question 36

Answer 36

I hate studying

Question 37

What fibers are found in tendons and ligaments and is resistant to pulling forces? (Looks like a handful of uncooked spaghetti)

Answer 37

Collagen Fibers

Question 38

What fibers are found in vocal cords, lungs, skin and blood vessels, lack tensile strength but can stretch and contract. (Coiled)

Answer 38

Elastic fibers (made of elastin)

Question 39

What fibers are composed of collagen and glycoprotein, and provide support around complex organs?

Answer 39

Reticular fibers

Question 40

What is a mesenchymal stem cell?

Answer 40

A cell that can transform into whatever cell is needed. Ex. chondroblast, osteoblast, tenoblast, or irregular connective tissue cell

Question 41

T/F Tendons hold bone to bone and limit movement

Answer 41

False; Tendons hold muscle to bone and enhance movement, while ligaments hold bone to bone and limit movement.

Question 42

Name the classes of cartilage

Answer 42
