Q

what is the function of simple columnar epithelium in the lining lumen of stomach and intestines ?

A

they help with secretion and absorption, also goblet cells release a mucin to aid in this process

Q

why is tissue psuedostratified named this?

A

named because at first glance it looks like it has multiple layers but it only has one layer that is attached to the basement layer

Q

what is the function of Ciliated Psuedostratified Epithelium in the bronchi and trachea?

A

the Cilia help propel dust particles and foreign materials away from the lungs, and nasal cavity and help move stuff through the trachea

Q

What is the shape of transitional epithelium

A

varies on appearance depending if its stretched or relaxed the basale layer will appear to be cuboidal, when stretched the apical layer will look more squamous

17
Q

why is it important that transitional epithelium stretch?

A

because this tissue is usually lining urinary bladder and ureters it is important that it stretches to prevent the toxins from urine to seep put into the body and other tissues and organs

18
Q

What are the different cell types that can be found in connective tissue

A 
Fibroblasts ( in most connective tissue)
Chondrocytes ( cartilage)
Osteocytes ( in bone)
Adipocytes ( adi[ose tissue)
Reticulocytes (Reticular tissue)
19
Q

What are the different types of fiber?

A

Collagen: Thick fibers which provide tensile strength
Elastic: Fibers which have the ability to stretch and recoil
Reticular
; short branching fibers which provide a supportive framework (stroma) for other cell types

20
Q

Name the cell that is found in Adipose connective Tissue

A

Adipocytes

21
Q

What is stored in Adipocytes

A

Fat

22
Q

What is the function of adipose connective tissue in the hypodermis?

A

it acts as an insulator to slow heat loss through skin

23
Q

What cells are found in Arreolar connective tissue ?

A

Fibroblasts

24
Q

What are the fibers present n Arreolar connective tissue?

A

elastic fibers and collagen fibers (minimal amount), they are arranged randomly

25
Q

where is arreolar connective tissue located?

A

you can see this formed as packaging around organs, around capillaries and in the hypodermis

26
Q

What is the cell type located in Dense Regular connective tissue

A

Fibroblasts

27
Q

What types of fibers are in dense regular tissue?

A

Collagen fibers, arranged parallel

28
Q

What is the location that dense regular connective tissue can be located?

A

tendons and ligaments

29
Q

What is the cell type that can be located in Dense Irregular Connective tissue?

A

Fibrolasts

30
Q

Does Dense Irregular connective tissue contain fibers?

A

Yes, it contains collagen fibers arranged randomly

31
Q

Where can dense irregular connective tissue be located?

A

dermis of the skin, fibrous capsule around organs and joints

32
Q

What is the cell type that is located in Elastic connective tissue ?

A

fibroblasts

33
Q

What fibers are located in elastic connective tissue?

A

elastic and collagen

34
Q

what location can you find elastic connective tissue

A

in the wall of the aorta, ligaments attached to vertebrae in the neck

35
Q

what cell type is located in reticular connective tissue?

A

fibroblasts and leukocytes

36
Q

What fibers are present in Reticular connective tissue

A

reticular fibers, that are arranged randomly

37
Q

where can the reticular connective tissue be located?

A

spleen, lymph nodes, bone marrow
