Tissue

Question 1

CNS regeneration

Answer 1

microglia - stem cells of the brain

Question 2

Muscle satellite cells

Answer 2

myosatellite cells (stem cells)

Question 3

Primary stem cell in connective tissue

Answer 3

Myosatellite cells pg.293

Question 4

Autophagy

Answer 4

Cell activity regulation

Question 5

Adipose tissue

Answer 5

Fatty tissues (areolar tissue can transform into adipose)

Question 6

Epithelial tissue

Answer 6

Epithelia - cells that cover external or line internal surfaces
glands -structures that produce fluid

Question 7

Edema

Answer 7

Swelling

Question 8

Three kinda of epithelia

Answer 8

Squamous, Cuboidal, Columnar (from appearance) pg.120

Question 9

Collagen

Answer 9

Flexible as rope, strong as steel pg130 (connective tissue fiber)

Question 10

Tissue repair

Answer 10

Division of stem cells

Question 11

What release causes inflammation

Answer 11

Mast cells pg.172

Question 12

Skin response to injury (what causes bleeding)

Answer 12

Mast cells release histamine,heparin, and prostaglandin, causing inflammation, (increased blood flow, pain), inflammation subsides, regeneration occurs

Question 13

Function of fibrocartilage callus

Answer 13

Matrix of dense fibers;
Absorbs shock, resists compression, prevents damage (bone to bone) limits movement

Question 14

Steps of tissue reconstruction

Answer 14

Inflammation
Migration
Proliferation
Scarring

Question 15

Malignancies from skin layers

Answer 15

Most cancers found in epithelial cells. Mutations in the nucleus can prevent recognition of cancer cells for apoptosis.

Question 16

Types of fracture

Answer 16

Open (compound) closed (simple) pg.201

Question 17

What closes epiphyseal plates

Answer 17

puberty causes cartilage to become narrow and seal creating an epiphysial line

Question 18

Maturation stage of wound healing

Answer 18

Scarring pg172

Question 19

Fx of ependymal cells

Answer 19

Type of neuroglia that protect and support neurons in the brain and spinal cord.
Ex: lines fluid filled passageways in brain and spinal cord

Question 20

Fx of oligodendrocyes

Answer 20

Form the myelinated sheath around the axon of a nerve cell (myelin are called internodes)

Question 21

Fx of microglia

Answer 21

Found in the CNS; remove cell debris, waste, and pathogens via phagocytosis

Question 22

Differentiation of skeletal muscle

Answer 22

Epimysium-outer layer, collagen, connected to deep facia
Perimysium- divides muscle into fascicles (compartments) collagen, nerves, and blood supply the fascicles
Endomysium - inside the fascicle, surrounds muscle cells; contains the stem cells needed for repair
