-Fibrous tissue
-Bone tissue
-Cartilage tissue
-Blood tissue
-Hematopoietic tissue

26

loose aleolar, adipose (fat) reticular and dense

A

Fibrous tissue

27
Q

compact and cancellous (spongy) tissue

A

Bone tissue

28
Q

Hyaline, fibrocartilage and elastic tissue

A

Cartilage tissue

29
Q

What are 3 types of Fibrous connective tissue

A

1: Loose fibrous connective tissue
2: Adipose (fat tissue)
3: Reticular tissue

30
Q

Fibrous glue (fascia) that holds organs together and facilitates communication among organs, collagenous and elastic fibers

A

Loose fibrous connective tissue (Areolar)

31
Q

white fat stores lipids (triglycerides), brown fat produces heat, both types regulate metabolism
Adipocyte is cell type

A

Adipose (fat) tissue

32
Q

Delicate net of supportive collagen fibers, as in bone marrow, spleen and lymph nodes

A

Reticular tissue

33
Q

bundles of strong collagen fibers, densely packed

A

Dense fibrous tissue

34
Q

Parallel collagen bundles, eg is Tendon

A

Regular dense fibrous tissue

35
Q

Chaotic, swirling collagen bundles, eg: deep layer of skin

A

Irregular dense fibrous tissue

36
Q

Matrix is collagen bundles is encrusted with calcium mineral crystals

A

Bone tissue

37
Q

3 Types of bone tissue

A

1: Compact bone
2: cancellous bone
3:Bone marrow

38
Q

Made of cylindrical osteons, forms outer wall of bones

A

Compact bone

39
Q

Made up of thin crisscrossing beams of matrix, also called spongy bone

A

Cancellous bone

40
