Q

Where is loose CT?

A

Beneath epithelial that cover tubes and cavities
Adipose Tissue is an example

23
Q

What is the purpose of loose connective tissue?

A

Site of immunological defense
Wbcs can move to CT form blood vessels

24
Q

How does loose CT look?

A

Messy with space ish

25
Q

What is dense irregular Tissue?

A

Thick collagen fibres in all directions

26
Q

Where is dense irregular Tissue found?

A

Skin dermis
Digestive tract
Capsuel of organs

27
Q

What is the function of dense irregular Tissue?

A

Able to withstand tension in many directions

28
Q

What 2 things can you see in dense Tissue?

A

Nuclei of fibroblasts
Collagen fibres

29
Q

What is dense regular tissue?

A

Closely packed unidirectional collagen fibres
Little vascularity

30
Q

Where is dense regular Tissue found?

A

Tendons and ligaments

31
Q

What is the function of dense regular connective tissue?

A

Attachment of muscles and bones
Withstand tensile strength when pulled in 1 direction

32
Q

What does ECM contain?

A

Fibres
Ground substance
Tissue fluid

33
Q

Whay fibres are present in connective tissue?

A

Collagen
Reticular
Elastic

34
Q

Where is elastic fibre found?

A

Aorta

35
Q

Where is reticular fibre found?

A

Lymph nodes

36
Q

Where eis collagen fibres found?

A

Tendons

37
Q

What are fixed (permanent) cells in ECM?

A

Fibroblasts
Macrophages
Adipocytes
mast cells

38
Q

What are transient cells in connective tissue?

A

WBCs

39
Q

What do fibroblasts do?

A

Synthesis collagen and ECM

40
Q

What are the types of muscle cells?

A

Skeletal
Cardiac
Smooth

41
Q

What do skeletal muscle have?

A

Lots of contractile protein
Multinucleated
Striated
Voluntary
Peripheral nuclei

42
Q

What do cardiac muscle have?

A

Involuntary
Heart
Single nucleated
Intercalated discs
Semi striated
Branched
Highly ordered

43
Q

What do smooth muscle have?

A

Muscle fibres
Single nucleated
Organs
Involuntary
Non Striated
Randomly ordered

44
Q

What are the 4 main aprts of a nerve?

A

Axon
Dendrites
Cell body
Terminals

45
Q

How are most glands formed?

A

Invagination of secretory epithelium into CT

46
Q

Structure wise
What is the difference between experience and endocrine glands?

A

Exocrine remains in contact with epithelium by ducts so the epithelium makes a U shape
(Stays connected to parent epithelium)

Endocrine looses contact so it can be secreted into a blood vessel making an O shape

47
Q

Give an example of a unicellular galnd

A

Goblet cells

48
Q

What are globular glands called?

A

Acinar

49
Q

What are the 2 types of exocrine glands?

A

Serous and mucous

50
Q

What is the difference between Serous and mucous glands

A

Serous secretes watery enzyme rich scetrion
Mucus is proteoglycan rich

51
Q

How to identify mucous secreting cells from serous ones?

A

Mucous ones have a paler staining with a peripheral nucleus

Serous are darker with a central nucleus

52
Q

What are the methods of exocrine secretion?

A

Apocrine pinches off the cell
Holocrine cell dies
Merocrine secrets it out

53
Q

What are myoepithoial cells?

A

Epithelial cells with contractile tissue to help expel secretions from gland lumens
