accounts for only 5 percent of skin
cancers
→ Arises from melanocytes

A

hair

15
Q

The central core of the hair, consisting of large cells and air spaces.

A

Central Medulla

16
Q

2 types of Sweat (Sudoriferous) Glands

A

Eccrine Glands
Apocrine Glands

17
Q

Surrounds the medulla; composed of several layers of flattened cells.

A

Cortex

17
Q

Located in the axilla and perineum.

Ducts empty into hair follicles in the armpit and genitals

Begin to function at puberty

Release sweat that also contains fatty acids and proteins (milky or yellowish color), which can develop an odor when bacteria decompose it

Play a minimal role in body temperature regulation

A

Apocrine Glands

18
Q

Part projecting from the skin.

A

Shaft

18
Q

Part of hair enclosed in the follicle.

A

Root

18
Q

The outermost layer of the hair, formed by a single layer of overlapping cells. This is the most heavily keratinized region of the hair, providing strength and helping to keep the inner layers compacted.

A

Cuticle

19
Q

Central medulla (core), cortex (bulky layer), and cuticle (outermost layer). The cuticle provides strength and can cause split ends when worn out.

A

Layer

20
Q

Associated hair structures

folli-bag)

Composed of an epithelial root sheath and fibrous sheath

Hair follicles are present in most skin areas except for specific regions like the palms and soles. The density and orientation of hair follicles vary by ethnicity.

A

hair follicle

21
Q

Supplies blood vessels to the hair bulb, the deepest part of the hair follicle.

A

Hair Papilla

22
Q

connects to the hair follicle to pull hairs upright when we are cold or frightened

A small band of smooth muscle cells that os connected to the hair follicle

When contracted, pull the hair upright and cause goosebumps.

A

Arrector Pili Muscle

23
Q

Produced by melanin granules depostode by melanocytes.

A

Hair Color

24
Q

We form all 8 million hair follicles by the 22nd week of fetal life.

true or false

A

false

We form all 5 million hair follicles by the 22nd week of fetal life.

A

rich blood supply in the underlying dermis.

26
Q

The tip of the nail that extends beyond the finger or toe.

27
Q

Skin folds that overlap the borders of the nail.

A

Nail Folds

27
Q

The thick proximal nail fold, also known as the eponychium, that covers the base of the nail.

A

Cuticle

27
Q

The stratum basale of the epidermis extends beneath the nail, responsible for nail growth.

A

Nail bed

27
Q

The thick, proximal area beneath the cuticle where nail growth occurs.

A

Nail Matrix

27
Q

Cover body surfaces
Line body cavities
Form protective sheets around organs

A

skin and body membranes

27
Q

skin and body membranes are classified to two tissue types:

A

epithelial membranes
connective tissue membranes

27
Q

Can be cutaneous (skin), mucous, or serous membranes.

A

epithelial Membranes:

27
Q

Example includes the synovial membrane.

A

Connective Tissue Membranes:

27
Q

Are considered as simple organs
Also called covering or lining membranes

A

EPITHELIAL MEMBRANES

27
Q

EPITHELIAL MEMBRANES contain: 2

A

Epithelial tissue layer
Connective tissue layer

28
Q

A dry membrane
Covers the body surface
Outermost protective boundary

A

Cutaneous Membrane

29
Q

construction of Cutaneous Membrane

A

epidermis and dermis

29
Q

: Composed of keratinized stratified squamous epithelium.

A

Epidermis

30
Q

: A protein in the epidermis that makes skin water-resistant.

A

Keratin

31
Q

: Primarily dense fibrous connective tissue.

A

dermis

32
Q

Moist membranes

Line all body cavities that open to the exterior body surface

Nasal cavity

Respiratory Tract

Adapted for absorption or secretion

A

Mucous Membrane

32
Q

Loose connective tissue beneath the mucosal epithelium.

A

Lamina Propria:

33
Q

Line open body cavities that are closed to the exterior of the body

A

Serous Fluid

34
Q

Loose areolar connective tissue only (no epithelial tissue)

Line fibrous capsules surrounding joints
- Line bursae
- Line tendon sheet

Secretes lubricating synovial fluid to cushion organs during muscle activity, preventing friction in joints.
