Epithelial

Tissue composed of layers of closely spaced cells that cover organ surfaces, form glands and serve for protection, secretion and absorption

Tissue with usually more matrix than cell volume, often specialized to support, bind and protect organs

Connective tissue

Nervous tissue

Contains excitable cells specialized for rapid transmission of coded information to other cells

Tissue composed of elongated, excitable muscle cells specialized for contraction

Muscular tissue

Cells of Fibrous connective tissue

1)Fibroblasts- large cells that produce fibers and form matrix



2) Macrophages- large phagocytotic cells, activate immune system



3) Leukocytes


4) plasma cells


5) adipose cells

Tight junction

Completely encircles an epithelial cell near its apical surface and joins it tightly to the neighboring cells.



Like plastic harness on soda cans

A patch that holds cells together, somewhat like the snap on a pair of jeans

Desmosome

Formed by a COnnexon, allow electrical excitation pass directly from cell to cell so cells contract.


NOT in skeletal muscle

Gap junction

Bone tissue: canaliculi

Delicate channels radiate from each lacuna to its neighbors.


Allow osteocytes to connect

Supports and organizes the glandular tissue


Connective tissue framework of gland

Stroma

Parenchyma

Cells that perform tasks of synthesis and secretion: function


Ex: parenchyma of lungs is elasticity

Melanin

Produced by melanocytes but accumulates in the kartinocytes of the stratum basal.


Skin color

Sudoriferous glands

Sweat glands- apocrine and merocrine

Sebaceous glands

Produce oily secretion called Sebum


Open directly Onto skin surface

Only found in external ear canal, where secretion combines with sebum wnd dead epidermal cells to form ear wax

Ceruminous glands

Merocrine sweat glands

Widely distributed over the entire body.


Abundant on palms, soles and forehead.


Cool the body through sympathetic nervous tissue

Functions of skin

Protection, containment, heat regulation, sensation and vitamin D

Functions of skin

Protection, containment, heat regulation, sensation and vitamin D

Epidermis layers

1.) stratum basale- push cells up


2.) stratum spinosum- clear


3.) stratum granulosum- flatten cells, destroyed living cells


4.) stratum Lucidum- regeneration


5.) stratum Corneum- cells fall off


(Come let's get sun burned)

Keratinocytes

The building blocks of tough fiberous protein keratin.


Waterproofing to hair, nails, skin

Langerhan cells of skin

Ingest unwanted invaders

Merkel cells

Combine with nerve endings to create a sensory receptor for touch

Thick skin

5 epidermal layers


(Palms of feet and hands)

Thick skin

5 epidermal layers


(Palms of feet and hands)

Thin skin

4 epidermal skin

Dermis

1.) papillary layer- areolar connective tissue, form ridges( finger prints)


2.) reticular layer- makes up 80% of dermis. Dense irregular


3.) hypodermis- adipose tissue, insulation, shock absorption

Jaundice

Liver disorder

Jaundice

Liver disorder

Vitamin D

Required to produce new bone cells

Hair structure

1) shaft- keratinization is complete


2.) root- keratinization is still happening

Eccrine sweat glands

Palms, forehead, feet


Coiled, tube leads to outside skin

Eccrine sweat glands

Palms, forehead, feet


Coiled, tube leads to outside skin

Apocrine gland

2,000 glands, start at puberty.


Groin, armpits


Secrete fat/protein. Oder.

Hair growth

Grows from dermal papilla.


1.) Anagen phase- growing, pushes out old hair


2.) categen phase- dying, growth stops, detaches from dermis papilla


3.) telogen phase- resting, lasts 6 months, cannot be repaired, dull

Round/ flat hair

More groups of protein, more hair will curl.



Shapes of follicle


Round- straight hair


Flat- curly hair
