Pd 4-DeAyndria and Micaela Podcast 3-Integ System Part 2.MP3

Javon-Pd 4-Integ System Podcast 2.MP3

Wednesday-10/4...CW: Finish labeling the Integumentary system and introduce the hair and nails...

HW: Review appropriate  text sections and always check webpage...

Thursday-10/5...CW: Skin and Hair Diagrams completed...Diagram completed for a grade...

HW: Final grade of 1st Quarter tomorrow...

***Video link on skin disorders below...

Skin cancer:

Benign-doesn't spread, non-fatal-needs to be removed

Malignant-fatal-spreads (called Metastasis)!!!

Eczema below-caused by??????

Tuesday-10/2...CW: diagram of integ system.....

3 Layers: Epidermis...Dermis...Hypodermis (adipose fatty layer)...

Epidermis: dead skin-hair-melanocytes-keratinocytes...

***Stratum granulosum and stratum germinosum are interchangeable names for the same 3rd layer on quiz...

Dermis:?????????????

Hypodermis?????????????

https://youtu.be/8v_YeDkrR9c

HW: read ch 6 and check webpage...Increase your study time to 1 hour if you are having trouble with material....

Bedsores:Decubitus ulcer-in dermis to dermis from not turning patients who have poor circulation...Know this!

For Diagram on Wednesday: Draw and Label the following:

In Dermis: Pacinian Corpuscles: pressure receptors

                    Meissner's Corpuscles: touch(tactile) receptors

                   Arrector Pili Muscles: produces goosebumps on skin

                  Papillary and Reticular Layer-one is superior to the other...

In Hypodermis (same as Subcutaneous): Adipose fat tissue...

BE PREPARED TO LABEL NAILS AND HAIR ON THURSDAY! DO NOT 'COPY' MY PICTURES BY PASTING THEM...

The objective in this Anatomy class is to build a body knowing structures-functions-and their location...by drawing them and memorizing 'EVERY' System...

memorization is aN INTEGRAL ROLE IN aNATOMY CLASS...

***All Students: Read the page on Skin Cancer 

(p. 121)...The mildest form of skin cancer from epidermal cells is called Basal Cell Carcinoma)carcinoma = cancer)...That is the type I have on my head: Know for test-it does not metastasize...Then the next serious one is squamous cell and the worse one-metastatic melanoma...bad news...

FOR HAIR LABELING: Know Hair Shaft, Hair Root, Sebaceous Gland, Arrector pili muscle, hair follicle (follicle surrounds the root)...

The hyponychium is the area of epithelium, particularly the thickened portion, underlying the free edge of the nail plate on the nail.

***The Toe below is identical to fingernail anatomy:

Know: Nail plate-nail bed Eponychium(cuticle) Nail root, Matrix, Lunula, Free Edge

Monday-10/2:...CW: Happy October...

Make-up quizzes today...

Intro to Integumentary system (skin)...short video and layers of skin...

HW:  read ch 6 text and always check webpage...

Below is video link from today...Watch it...

**Try Quizlet for amazing memory games and my study flashcard sets...It is for 'student memory retention.....My user name is katman 3...let me know if I can help you with it...

Key vocabulary:

 Keratin:  waterproof protein in epidermis produced by keratinocytes-                                                keeps the skin moist...

Melanin-pigment of skin color produced by Melanocytes in bottom                          epidermis...

Tactile (Touch) receptors-in Dermis

Vascular: Blood vessels in dermis

Avascular: Without blood vessels

Adipose: fat tissue(Subcutaneous)

Sudoriferous (Sweat) glands-Dermis

Sebaceous (Oil) glands-Dermis

Dermal Papillae (Fingerprints) in Dermis

Arrector Pili: Muscle in Dermis that causes 'Goosebumps'

Pressure receptors: Pacinian corpuscles

Tactile: Meissner's corpuscles

Sebaceous glands-oil

Sudoriferous glands(sweat): 2 types:

*** Apocrine-Eccrine

Apocrine glands develop in areas abundant in hair follicles, such as your armpits and groin, and they empty into the hair follicle just before it opens onto the skin surface. When your body temperature rises, your eccrine glands secrete fluid onto the surface of your skin, where it cools your body as it evaporates.

***The  thickest layer of the epidermis is the stratum spinosum-layer 4...

If you wish to stay ahead, here are Dermis layer structures we will add tomorrow:

1. Arrector pili muscle(Goosebumps)

2. Sebaceous(oil) gland

3. Sudoriferous (sweat) glands

4. Hair Follicles

5. Nerve cells

6. Meissner corpuscles(tactile) receptors

7. Dermal papillae(Fingerprints)

8. Papillary layer(near epidermis): loose conn. tissue

9. Reticular layer: lower dermis of dense connective tissue

10. Blood vessels-arteries, veins , capillaries
