Q

Goblet cells

A

Cells that make and secrete mucus protein

20
Q

Goblet cells are in what tissues

A

Simple columnar, pseudostratified columnar

21
Q

Connective tissue

A

Connects different body parts: most abundant tissue

22
Q

Connective tissue functions

A

Protecting, supporting, and binding together body tissues

23
Q

General structure of connective tissue

A
  1. Vascular (good blood supply)

2. Surrounded by ECM

24
Q

Structure of the ECM

A

Ground substance composed mainly of water plus proteins and polysaccharides.
(Collagen and elastin)

25
Q

ECM proteins are connected to the cell membranes by

A

Integrin proteins

26
Q

Seven types of connective tissue

A

Bone, dense fibrous tissue, blood, reticular tissue, cartilage, loose connective tissue, hematopoietic

27
Q

Bone structure and function

A

Structure: concentric circles that are bound together by a calcified ECM
Function: support

28
Q

Cartilage tissue is more flexible than bone because it has

A

Less calcification

29
Q

Structure and function of cartilage tissue

A

Structure: made primarily of collagen protein
Function: provide structure with flexibility

30
Q

Three types of cartilage tissue

A

Hyaline, elastic and fibrocartilage

31
Q

Hyaline cartilage

A

Abundant collagen fibers in a matrix with a classy, smooth appearance

32
Q

Hyaline cartilage locations

A

Larynx, trachea, sternum, surfaces of bones at the joints

33
Q

Fibrocartilage

A

Compact cartilage: between the vertebral disks of the spine

34
Q

Elastic cartilage

A

Very loose, flexible cartilage: ear

35
Q

Dense fibrous connective tissue

A

Forms parallel bundles of strong rope like fibers

36
Q

Structure and function of DFCT

A

Structure: tightly woven, very compact collagen fibers; few cells
Function: forms the ligaments, tendons and dermis layer of skin

37
Q

Loose connective tissue

A

Tissue that is less tightly compacted and organized

38
Q

Structure and function of loose connective tissue

A

Structure: has fewer collagen fibers than other tissues and contains more cells
Function: provides packaging, cushioning, and storage

39
Q

Two types of loose connective tissue

A

Areolar and adipose

40
Q

Areolar tissue

A

Structure: has collagen fibers interspersed and a watery, gel like matrix
Location: Lungs, attaches skin to tissues, surrounds blood vessels
Functions: packages organs and provides a storage site for water, salts and minerals

41
Q

Adipose tissue: fat

A

Structure: plump sells filled with fat droplets; cells appear empty
Function: stores fats and cushions organs

42
Q

Blood or vascular tissue

A

Only fluid tissue

Function: connects organs to each other for nutrient flow; has liquid ECM

43
Q

Hematopoietic

A

Bone marrow; contains stem cells and is the site for red blood cell formation

44
Q

Reticular tissue

A

Contains interwoven reticular fibers that form a base of support
Location: lymph nodes and spleen

45
Q

Three types of muscle tissue

A

Cardiac, smooth, and skeletal

46
Q

Nervous tissue

A

Regulates and controls bodily functions and activity; the brain and spinal cord
