Q

Under psychological or emotional
stress (cold/fright), autonomic nerve
endings stimulate the arrector pili

Q

 Simple, branched, acinar (rounded) glands
 Opens to the neck follicle
 Present at the lips, glans penis, labia
minora, tarsal glands of the eyelids,

A

Sebaceous glands

17
Q

Secretes SEBUM
 Coats surface of hair and helps them from
drying and becoming brittle.
 Prevents excessive evaporation of water
from the skin, making it soft and pliable

A

Sebaceous hland

18
Q

 Releases sweat, or perspiration
A. ECCRINE SWEAT GLANDS present when?
B. APOCRINE SWEAT GLANDS present when?

A

Sudoriferous glands

present at birth
develop during puberty only

19
Q

______________________
: sweat that evaporates
the skin before it is perceived as moisture
 _______________________: Sweat that is excreted in larger amts and seen as moisture on the skin

THIS IS PRT OF ECCRINE SWEAT AND

A

Insensible perspiration

Sensible perspiration

20
Q

Release sweat in response to emotional stress such as fear or embarrassment (palms, soles and axilla)

A

EMOTIONAL SWEATING/COLD SWEAT:

21
Q

Simple, coiled, tubular glands
 Axilla, groin, areola of breasts, bearded regions around the face
of adult males.
 SECRETORY PORTION: Deep dermis and upper subq layer
 EXCRETORY PORTION: Hair follicles
 Appears milky and yellowish in color

A

APOCRINE SWEAT GLANDS

22
Q

Apocrine sweat interacts with bacteria, bacteria metabolizes the components causing the MUSKY ODOR, thus called BODY
ODOR.

A

just get it

23
Q

 Modified sweat glands in the external ear
 Produces waxy lubricating secretion
 SECRETORY PORTION: Subcutaneous layer
 EXCRETORY PORTION: Surface of EAM/ducts of sebaceous

A

Ceruminous Glands

24
Q

yellowish combination of
ceruminous and sebaceous sweat glands
 Provides a sticky barrier to impede the entrance of foreign bodies
and insects
 Waterproofs the canals and prevents bacteria and fungi to form

A

Cerumen/Earwax

25
Q

● Tightly packed, hard, dead,
keratinized epidermal cells

A

B.???: nail body that may
extend past the distal end of the
digits
C.???- nail that is buried in
the fold of the skin

A

NAIL ROOT/ PLATE

FREE EDGE

NAIL ROOT

27
Q

D.???: whitish, crescent area of
the proximal end of the nail body
E.???: secures the nail
to the fingertip
F.???: skin below the nail
plate that extends from the lunula and
hyponychium (lacks granulosum)

A

LUNULA

HYPONYCHIUM

NAIL BED

28
Q

real name of nails

A

Onychia / Onychium

29
Q

G.???:
occupies the proximal border of
the nail and lacks corneum

H.??? Portion of
the epithelium proximal to the nail
root

A

EPONYCHIUM/CUTICLE

NAIL MATRIX:

30
Q

● Edges of the wound usually involved only slight
damage to superficial epidermal cells.
● COMMON: ABRASION (portion of the skin is
scraped away), MINOR BURNS
