Q
  • -ducts of large glands

- -rare in body

A

Stratified cuboidal and columnar

23
Q
  • most abundant tissue in body
  • highly vascular for most types
  • have matrix between cells
  • bears weight, stretches
  • high rate of mitosis
  • protects, support
  • matrix can absorb large amounts of water and store it
A

Characteristics of Connective Tissues

24
Q

Is water with protein fibers, the consistency of the fibers determines the tissue

A

Matrix

25
Q

-bone cells sit in Lacunae (spaces) surrounded by a hard matrix of calcium salts and collagen

A

Bones (Osseous tissue)

26
Q

-more flexible than bone

A

Cartilage

27
Q

Types of Cartilage

A
  1. Hyaline
  2. Fibrocartilage
  3. Elastic
28
Q
  • found in the larynx, ribs to the sternum

- covers ends of bones

A

Hyaline

29
Q

-disks between vertebrae

A

Fibrocartilage

30
Q

-ear

A

Elastic

31
Q

-collagen is main fiber in matrix, fibroblasts produce it

A

Dense connective tissue (dense fibers)

32
Q

Types of connective dense tissue

A
  1. Tenuous

2. Ligaments

33
Q

-connect bones to muscles

A

Tenuous

34
Q

-connect bones to bones, move stretchy than tendons

A

Ligaments

35
Q

-more cells and fewer fiber than the above tissue has

A

Lose Connective Tissue

36
Q
  • soft, pliable, crush ions and protects body organs
  • holds organs in position and together
  • inflammation occurs when this tissue soaks
  • up fluid, causes sweeping –Edema
A

Areolar Tissue

37
Q
  • most of the cell is an oil droplet
  • hips, breasts, kidneys, eye sockets, under skin
  • not equally distrusted throughout

3 Jobs

  1. Energy
  2. Insulation
  3. Shock absorption
A

Adipose

38
Q
  • interwoven fibers

- found in lymph nodes, spleen, bone marrow

A

Reticular connective tissue

39
Q

-matrix is plasma

A

40
Q

Red Blood Cells

-carries O2 and CO2

A

Erythrocytes

41
Q

White blood cells

- fights invaders

A

Leukocytes

42
Q

Platelets

-clotting blood

A

Thrombocytes

43
Q
  • *Muscle Fibers

A

Neurons (nerve cell)

49
Q

-carry information from senses toward the brain and spinal cord

A

Sensory

50
Q

-carry information from the brain and spinal cord to a muscle (then it moves) or to a gland (then it secrets something)

A

Motor

51
Q

-sort information with in the brain or spinal cord

A
