Flashcards in BS Deck (42):
1

Macule

1 Flat, circumscribed discoloration <1cm

2

Patch

1 Flat, circumscribed discoloration >1cm

3

Papule

1 Elevated solid lesion <1cm. Dermal or subdermal

4

Plaque

1 Circumscribed, slightly raised lesion >1cm. May be confluence of papules. Color & surface change

5

Nodule

1 Circumscribed, palpable lesion > 1 cm.epidermis plus dermis, dermis & subcutis of subcutis alone

6

Wheal

1 Itchy, pink or red swelling of the skin. Central pallor, transient.

7

Vesicle

1 Circumscribed collection of free fluid up to 0.5 cm diameter

8

Bulla

1 Circumscribed free fluid >0.5cm. Tense, flaccid or weepy

9

Pustule

1 Leukocytes, may be sterile or purulent. Superficial, heal w/o scar.

10

Erosion

2 focal loss of epidermis, no scarring

11

Ulcer

loss of epidermis- scarring except mucus membranes. Boarders rolled, undermined, punched out

12

Atrophy

2 Thinning and transparency of skin- diminution of epidermis, dermis or both. wrinkling & transparency. Age & steroid use

13

Scales

2 Excess dead epidermal cells- abn keritinzation

14

Crusts

2 Dried exudate- serous, purulent or haemorrhagic

15

Scar

2 Formation of CT implying dermal damage

16

Hypertrophic Scar

2 firm nodules, papules or plaques over original site of injury

17

Keloid

2 Exceeds area of initial injury with web like projections

18

Fissues

2 Linear loss fo epidermis and dermis with sharply defined, vertical walls

19

Purpura

Special- nonblanching extravasation of blood

20

Petechiae

Special- tiny pinpoint purpuric lesions

21

Telangectasia

Special- persistant dilations of small capillaries

22

Eccymosis

Special- larger purpuric patches- noninflammatroy

23

Cyst

Special- encapsulated sac lined with epithelium containing fluid- spherical or oval, resilient by palpations

24

Comedone

Open or closed- aka black head- pilosebacious unit. accumulates pertinacious material

25

Burrow

threadlike tunnel through epidermis

26

Lichenification

reactive thickening of epidermis from repeated rubbing

27

Excoriation

scratching resulting in excavations of epidermis

28

Compact bone

hard, outer shell- gives bone strength- 80% skeletal mass

29

Trabecular bone

honeycomb like tissue in center of bones- active site of remodeling, bone marrow, high surface to volume ratio

30

Periosteum

Outer membrane covering bone, where muscles, ligaments attach

31

Osteoblast

Cells forming bone- lay down matrix by secreting proteoglycans & collagen

32

Osteoclast

Multinucleate cells. resorb & dissolve bone

33

Osteocyte

derived from blast cells- direct bone remodeling and sense mechanical strain

34

Fascia

Dense layers of fibrous CT- cover and connect skeletal muscles & form boundries

35

Superficial fascia

thin layer of adipose tissue underlying dermis- binds skin to bone

36

Deep fascia

binds muscles in muscle group and other internal structures

37

Tendon

fibrous CT connecting muscles to bones

38

Ligament

Band or sheet of strong CT connecting articular ends of bones to limit ROM

39

Cellulitis

Most superficial- infection of skin and subcutaneous tissue. Can spread through lymph

40

Fasciitis

Inflammation of the fascia covering muscle, vessels, nerves and bones

41

Myositis

Deepest- inflammation of the muscle

42

Fascial planes

Compartments of connective tissue. Anatomic highway to spread infection. No blood supply to clear infection
