Q

Stratified with upto 10 layers of variable, roughly cuboidal cells that distort to squamous shape when stretched, function for stretch as in urinary bladder lining

A

Transitional epithelium

24
Q

what type of tissue is this
-most abundant and widely distributed tissue in body

A

Connective tissue

25
What are 5 types of connective tissue
-Fibrous tissue -Bone tissue -Cartilage tissue -Blood tissue -Hematopoietic tissue
26
What kind of tissue: loose aleolar, adipose (fat) reticular and dense
Fibrous tissue
27
compact and cancellous (spongy) tissue
Bone tissue
28
Hyaline, fibrocartilage and elastic tissue
Cartilage tissue
29
What are 3 types of Fibrous connective tissue
1: Loose fibrous connective tissue 2: Adipose (fat tissue) 3: Reticular tissue
30
Fibrous glue (fascia) that holds organs together and facilitates communication among organs, collagenous and elastic fibers
Loose fibrous connective tissue (Areolar)
31
white fat stores lipids (triglycerides), brown fat produces heat, both types regulate metabolism Adipocyte is cell type
Adipose (fat) tissue
32
Delicate net of supportive collagen fibers, as in bone marrow, spleen and lymph nodes
Reticular tissue
33
bundles of strong collagen fibers, densely packed
Dense fibrous tissue
34
Parallel collagen bundles, eg is Tendon
Regular dense fibrous tissue
35
Chaotic, swirling collagen bundles, eg: deep layer of skin
Irregular dense fibrous tissue
36
Matrix is collagen bundles is encrusted with calcium mineral crystals Osteocyte is cell type
Bone tissue
37
3 Types of bone tissue
1: Compact bone 2: cancellous bone 3:Bone marrow
38
Made of cylindrical osteons, forms outer wall of bones
Compact bone
39
Made up of thin crisscrossing beams of matrix, also called spongy bone
Cancellous bone
40
Matrix has consistency of gristlelike gel Chondrocyte is cell type
Cartilage tissue
41
moderate amount of collagen in matrix, forms a flexible gel
Hyaline cartilage
42
Matrix is very dense with collagen, forms very tough hard gel
Fibrocartilage
43
Matrix has some collagen with elastin, forms a soft elastic gel
Elastic cartilage
44
matrix is fluid plasma, functions are transportation and protection, contains red blood cells, white blood cells and platelets
Blood tissue
45
Blood forming tissue with a liquid matrix
Hematopoietic tissue
46
Contracts to provide movement or stability, produces body heat
Muscle tissue
47
attaches to bones, also called striated voluntary, control is voluntary, striations apparent when viewed under a microscope
skeletal muscle tissue
48
Also called striated involuntary, composes heart wall, ordinarily cannot voluntarily control contractions
Cardiac muscle tissue
49
Also called non striated (visceral) or involuntary, no cross striation, found in blood vessels and other tube shaped organs
smooth muscle tissue
50
Rapid communication between body structures and control of body functions
Nervous tissue
51
impulse conducting cells
Neurons
52
2 types of processes of all neurons
axon and dendrite
53
carries nerve impulse away from the cell body
Axion
54
recieve signals from other neurons
Dendrites
55
Supportive and connecting cells
Glia (neuroglia)
