Q

What are connective tissues derived from?

A

Embroynic tissue called mesenchyme.

23
Q

What are some of the main functions of connective tissues?

A

They bind structures together. Provide support and protection, fill spaces, store fat and transport blood cells.

24
Q

Differences between epithelial cells and connective tissues?

A

Connective tissue cells are not as close together as epithelial cells are and are often widely scattered in an abundance of a noncellular extracellular matrix.

25
Q

What is the extra cellular matrix in regards to connective tissue?

A

The extracellular matrix varies in quantity and form depending on the specific tissue type and is like a filler material between the cells.

26
Q

What do the cells of connective tissue produce and secrete?

A

Two components of the extra cellular matrix known as the ground substances and fibers.

27
Q

What is the ground substance?

A

The ground substance varies from a liquid to a semisolid to a solid and has functions in support and as a medium for substances to move between cells and blood vessels.

28
Q

What are the fibers of the extracellular matrix?

A

They consists of fibrous proteins including collagen, elastic and reticular.

29
Q

What do the fibers provide?

A

The fibers provide the binding properties within the tissue and between the organs.

30
Q

Describe collagen fibers :

A

Collagen fibers are thick threads, the most abundant of the three types and are white in unstained tissues.

31
Q

Describe elastic fibers :

A

Elastic fibers form complex networks of a highly branched protein called elastin.

32
Q

Describe reticular fibers :

A

Reticular fibers are fine threads of highly branched collagen with glycoprotein.

33
Q

Forms framework of outer ear

A

Elastic Cartilage

34
Q

Functions as heat insulator beneath skin

A

Adipose

35
Q

Contains large amounts of fluid and transports nutrients, wastes, and gases

A

Blood

36
Q

A

Bone (compact)

37
Q

Binds skin to underlying organs

A

Areolar connective

38
Q

Main tissue of tendons and ligaments

A

Dense Connective Tissue (regular)

39
Q

Forms the flexible part of the nasal septum and the ends of long bones

A

Hyaline caritlage

40
Q

Pads between vertebrae that are shock absorbers

A

Fibrocartilage

41
Q

Occurs in some ligament attachments between vertebrae and larger artery walls

A

Elastic connective tissue

42
Q

Forms supporting tissue in walls of thymus and spleen

A

Reticular connective tissue

43
Q

Main tissue of dermis

A

Dense irregular

44
Q

Cells in a fluid gel-like matrix with parallel collagen fibers

A

Dense regular

45
Q

Contains loose arrangement of elastic and collagen fibers

A

Elastic connective

46
Q

What is an osteoblast?

A

immature bone cells

47
Q

What is an osteocyte?

A

mature bone cells

48
Q

What is the cutaneous membrane?

A

Cutaneous membrane, or skin, is an organ system consisting of a keratinized squamous epithelium (epidermis) firmly attached to a thick layer of dense irregular connective tissue (dermis)

49
Q

What is a mucous membrane?

A

Mucous membranes line body cavities that open to the exterior, such as those of hollow organs of the digestive, respiratory, and urogenital tracts

50
Q

What is serous membrane?

A

Between the visceral and parietal membranes, thin fluid

51
Q

What are endocrine glands?

A

Produce hormones: regulatory chemicals that they secrete by exocytosis directly into the extracellular space
Ductless glands

52
Q

What are exocrine glands?

A

Secrete their products onto body surfaces (skin) or into body cavities:

53
Q

What are the three skin pigments?

A

Melanin, Carotene, Hemoglobin
