15. Characteristics of Connective Tissue
Connective tissues have varying degrees of vascularity
Some have a few blood vessels and some have many

16. Characteristics of Connective Tissue
Connective tissues also have a nonliving extracellular matrix, consisting of ground substance and fibers

18. anatomy: Structural Elements of Connective Tissue
Connective tissue has three components:
Ground substance – fills the space between cells
Fluids and proteins
Fibers – collagen, elastic, or reticular
Cells – fibroblasts, chondroblasts, osteoblasts, and hematopoietic stem cells

19. anatomy: Structural Elements of Connective Tissue
Connective tissue has three components:
Ground substance – fills the space between cells
Fluids and proteins
Fibers – collagen, elastic, or reticular
Cells – fibroblasts, chondroblasts, osteoblasts, and hematopoietic stem cells

20. anatomy: Structural Elements of Connective Tissue
Connective tissue has three components:
Ground substance – fills the space between cells

Cells – fibroblasts, chondroblasts, osteoblasts, and hematopoietic stem cells

21. anatomy: Structural Elements of Connective Tissue
Connective tissue has three components:
Ground substance – fills the space between cells
Fluids and proteins
Fibers – collagen, elastic, or reticular
Cells – fibroblasts, chondroblasts, osteoblasts, and hematopoietic stem cells

22. Don’t forget to chunk your notes!

23. fibers Collagen: tough; provides high tensile strength
: resist stretching

24. Elastic: long, thin fibers that allow for stretch

25. fibers
Reticular: branched collagenous fibers that form delicate networks
: Strong but allow more “give” than collagen

27. Connective tissue proper: loose
Areolar Connective Tissue
Wraps and cushions organs
Holds and moves tissue fluids
Found in almost every part of the body, especially near epithelial tissues
Skin
Around blood vessels, nerves and organs

28. Connective tissue proper: loose
Adipose Connective Tissue
Commonly called fat tissue
Stores fat (energy), insulates against heat loss, and supports and protects
Found under skin, around kidneys, within abdomen, and in breasts

29. Connective tissue proper: loose
Reticular Connective Tissue
Supports lymphatic system organs
Found in lymph nodes, bone marrow, and the spleen

30. Don’t forget to chunk your notes!

31. Connective tissue proper: dense
Dense Regular
Attaches muscles to bone (Tendons), muscle to other muscles, and bone to bone (ligaments)
Found in tendons, ligaments, and aponeuroses (muscle attachments)

32. Connective tissue proper: dense
Dense Irregular
Protection: Withstands tension in many directions providing structural strength
Found in the dermis (skin layer), submucosa (membranes) of the digestive tract, and fibrous organ capsules (coverings)

33. Don’t forget to chunk your notes!

34. cartilage Hyaline Cartilage
Supports, reinforces, cushions, and resists compression
Forms the costal cartilage (between ribs)
Found in embryonic skeleton, the end of long bones, nose, trachea, and larynx

35. cartilage Elastic Cartilage
Maintains shape and structure while allowing flexibility
Supports external ear (pinna), larynx and the epiglottis

36. Fibrocartilage Cartilage
Provides tensile strength and absorbs compression shock
Found in intervertebral discs, the pubic symphysis, and in discs of the knee joint

37. Don’t forget to chunk your notes!

38. Bone Osseous Tissue Makes up the skeleton Supports Protects
Provides levers for muscular action
Stores calcium, minerals, and fat
Marrow creates blood cells (hematopoiesis)

40. blood Blood Found within blood vessels
Functions in the transport of respiratory gases, nutrients, and wastes
Fights infections
