16
Q

Where is mesenchyme found and what’s its function?

A

Fetus and embryo. Gives rise to all other types of connective tissue

17
Q

What are the two types of loose connective tissue?

A

Areolar and Adipose

18
Q

What type of matrix is in areolar tissue and what cells are present?

A

Gel-like and fibroblasts, macrophages, mast cells and some WBC

19
Q

Where can you find areolar tissue?

A

Under epithelial tissue, packages organs and surrounding capillaries

20
Q

What is the structure of adipose tissue?

A

Has a matrix and highly vascularized

21
Q

Where can you find adipose tissue

A

In spaces between organs and surrounding blood vessels

22
Q

What are the two types of dense connective tissue?

A

Dense regular and dense irregular connective tissue

23
Q

What is the difference between loose and dense connective tissue proper?

A

Dense has thicker fibers and fewer cells

24
Q

What are two examples of dense connective tissue proper

A

Tendons and ligaments

25
Q

What is the only connective tissue without blood vessels?

A

Cartilage

26
Q

What is the function of cartilage? Mature connective tissue (supportive)

A

Supports, reinforces, cushions and resist compressive stress

27
Q

What is the structure of bone? Mature connective tissue (supportive)

A

Hard, calcified matrix. Contains collagen fibers and osteocytes. Very well vascularized

28
Q

What is the function of bone? (connective tissue)

A

Supports and protects, provides levers for the muscles. Stores calcium, minerals and fat.

29
Q

what are the cells in blood, fluid mature connective tissue?

A

Lymphocytes and erythrocytes

30
Q

what is the structure of lymph, fluid mature connective tissue?

A

Liquid matrix, no red blood cells and clear/white fluid.

31

A

Skeletal, cardiac and smooth

32
Q

What is the structure of skeletal muscle tissue?

A

Striated, long and cylindrical. Nucleus pushed to the outsides

33
Q

Where is skeletal muscle located?

A

Attached to bones or occasionally to the skin

34
Q

What is the structure of cardiac muscle?

A

Branched, striated with intercalated discs

35
Q

Where is cardiac muscle located?

A

The walls of the heart

36
Q

What is the structure of smooth muscle?

A

Spindle shaped with no central nuclei, arranged in sheets

37
Q

What is the function of smooth muscle?

A

Propels substances or objects along internal passage ways.

38
Q

Where is smooth muscle located?

A

In the walls of hallow organs

39
