large branched glands usually
opening through the hair sheaths along with
sebaceous glands
-cerumen/earwax

CERUMINOUS

– transmits impulses
from soma to synapse

Axon

1st major skin region (outside

EPIDERMIS

is the process by which stimulus causes a response which will increase the stimulation * “Intensifies” * “promotes further change” * Stops only when stimulus is remove

POSITIVE FEEDBACK

This type of tissue all develop from the mesenchyme found in the embryo. The cells are loosely arranged and are supported by a solid or liquid matrix.

CONNECTIVE TISSUE

- layers with cells slightly separated by tissue fluid but joined by delicate extensions of cytoplasm (skin strength and flexibility

STRATUM SPINOSUM

translucent layer where nails originate. Palms and soles

STRATUM LUCIDUM

Strands of tightly - packed dead and keratinized cells originating from the hair follicle

HAIR

Short branching shape Have few striations, single nucleus /two nucleus

STRIATED INVOLUNTARY MUSCLE OR CARDIAC MUSCLE

(outermost layer of the skin) * Thin, scaly-look like, flattened on the surface, fried-egg appearance with rounded nucleus.

SQUAMOUS EPITHELIUM

Spindle in shape of cells, one nucleus located at the center, absent of striations

SMOOTH INVOLUNTARY MUSCLE OR VISCERAL MUSCLE

– specialized for production of germ cells. Source: gonads (ovary and testis)

GERMINAL EPITHELIUM

(lining of kidney tubules) * Dice shape, square-like shape with large and spherical nucle

CUBOIDAL EPITHELIUM

This tissue lines outer and inner surfaces of the body. In most types of epithelial tissue, the cells are compactly arranged and rest on a basement membrane

EPITHELIAL TISSUE

is the process when the receptor detect change and initiate response that will go against the change. * Reverse * Reduce the change * “bringing back again

NEGATIVE FEEDBACK

specialized connective tissue which transports substances

BLOOD

fibers in the matrix are compactly arranged

DENSE CONNECTIVE TISSUE

self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal forsurvival.

HOMEOSTASIS

supporting cells which has the following

Neuroglia

This tissue is specialized for the reception of stimuli and transmission of impulses.

NERVOUS TISSUE

specialized for secretion Source: glands

GLANDULAR EPITHELIUM

the cell body containing the nucleus

Soma

milk secreting, compound alveolar glands which fully develop only during pregnancy

MAMMARY

This tissue is specialized for contraction

MUSCULAR TISSUE

produced by melanocytes

Melanin:

type of gland small alveolar glands usually formed close to hairs absent on palms and soles sebum/oil

SEBACEOUS

process in which new cells (with keratin) push old cells to surface. 40- 56 days for new cells to reach surface

Keratinization:

dead cells that are shed off at intervals; responsible for variations in skin thickness

STRATUM CORNEUM

made up of one layer of cells but of different heights, thus showing a stratified appearance. Source: inner lining of trachea

PSEUDO STRATIFIED

tubular coiled glands that open in sweat pore on the surface of the skin secreting a clear fluid o Much more numerous o Most abundant in palms, soles, & forehead

ECCRINE

state of balance in the body

HOMEOSTASIS

The brain

INTEGRATOR

made up of more than two layers of cells. Source: epidermis
