Q

Epithelium characteristics

A

Cells fit closely together Tissue layer always has one free surface The lower surface is bound by a basement membrane Avascular- (have no blood supply) Regenerate easily if it is nourished

Q

Pseudostratified

A

Single layer but some cells are shorter than others Often looks like a double cell layer Sometimes ciliated such as in the respiratory tract

18
Q

Two elements of tissues

A

Ground substances- mostly water along with adhesion proteins and polyscchrides molecules Fibers produced by cell

19
Q

Bone( osseus tissue)

A

Composed of bone cells in lacunae( cavities) Hard matrix of calcium salts Large numbers of collagen fibers Used to support and protect body

20
Q

Hyaline cartilage

A

Most common Composed of: abundant collagen fibers Rubber matrix The entire fetal skeleton is made of this

21
Q

Fiber cartilage

A

Highly compressible And example: forms cushion like discs between vertebrae

22
Q

Dense connective tissue

A

Main matrix element is colleges fibers Cells are fibroblasts Ex: tendons and ligaments

23
Q

Tendons

A

Muscle to bone

24
Q

Ligament

A

Bone to bone

25
Q

Areolar

A

Most widely distributed tissue Soft and pliable Contains all fiber types Can soak up excess fluid

26
Q

Adipose

A

Matrix is an Areolar Tissue in fat globules Many cells contain large lipid deposits Functions: Insulate body Protects some organs Serves as site of fuel storage

27
Q

Reticular connective tissue

A

Delicate network of interwoven fibers Forms stroma( internal supporting network of): Lymph nodes Spleen Bone marrow

28
Q

Blood

A

Blood cells surround by fluid matrix Fibers visible during clotting Functions as transport vehicle for material

29
Q

Function of muscle tissue

A

Produce movements

30
Q

Skeletal muscle

A

Can be controlled voluntarily Cells attached to connective tissue Cells are striated Cells have more than one nucleus

31
Q

Cardiac muscle

A

Found only in the heart Function is to pump blood involuntarily Cells attached to other cardiac muscle cells are intercalated disks Cells are striated One nucleus per cell

32
Q

Smooth muscle

A

Involuntary muscle Surrounds hallow organs Attached to other smooth muscles cells No visible striations One nucleus per cell

33
Q

Nervous tissue

A

Neurons and support cells or neuroglial cells Functions to send impulses to other areas of the body

34
Q

Regeneration

A

Replacement of destroyed tissue by same kind of cells

35
Q

Fibrosis

A

Repair by dense fibrous connective tissues(scar tissue)

36
Q

Capillaries become what during tissue repair

A

Permeable and they introduce clotting proteins to wall off injured area

37
Q

Second and third step of tissue repair

A

Formation of granulation tissue Regeneration of surface epithelium

38
Q

Tissues that regenerate easily

A

Epithelial tissue Fibrous connective tissue Bone

39
Q

Tissue that regenerate poorly

A

Skeletal muscle

40
Q

Tissues that are replaced largely by scar tissue

A

Cardiac muscle Nervous tissue within brain and spinal chord

41
