TRUE / FALSE
The skin consists of 2 layers:
1. Epidermis (outermost protective layer of dead keratinized epithelial cells).
TRUE / FALSE
The layers of the epidermis, from the OUTER layer to the INNER layer are
Stratum corneum (most outer layer), Stratum lucidum, stratum granulosum & the (inner most)stratum germinativum (basal).
Epidermal cells contain the protein pigment called
What is melanin's function?
Protect against radiation from the sun
inner layer of the skin
What are the 4 things that makeup the Dermis?
Fibrous connective tissue w/blood vessels, sensory nerve endings, hair follicles & glands.
What are the 2 types of sweat glands?
Eccrine & Apocrine
Eccrine sweat glands
They are distributed all over the body (except for the lips, tip of penis and clitoris). Regulates body temperature by releasing a water secretion that evaporates from the surface of the skin.
Apocrine sweat glands
mainly in the armpits & groin area, display apocrine secretion.
release an oily secretion (sebum) through the hair follicles that lubricates the skin & prevents drying.
Oil is produced by
holocrine secretion, in which whole cells of the gland are part of the secretion. *These glands are susceptible to becoming clogged & attracting bacteria, particularly during adolescence.
The appendages of the skin include
hair & nails.
Hair and nails are composed of a strong protein called
What does the body framework consist of?
Bone, cartilage & ligaments, plus the joints between the bones.
Functions of the skeletal system include
support, permission of movement, blood cell formation (hemopoiesis), protection of internal organ, detoxification (removal of poisons), provision for muscle attachment & mineral storage.
Calcium & Phosphorus are minerals stored in the
TRUE / FALSE
Long bones: relatively long, slender; found in the arms, legs, thighs, palms, soles, fingers and toes. Has an irregular epiphysis @ each end, composed of mainly spongy (cancellous) bone & a shaft or diaphysis composed mainly of compact bone.
Short bones: somewhat cube-shaped; of nearly equal length and width.
Flat bones: thin, flat surfaces, no marrow cavity, but spongy bone sandwiched between an upper and lower layer of compact bone.
Irregular bones: complex shapes; notched, or with ridges; not easily classified into any other category. Example: vertebrae; some facial bones (like the ethmoid or sphenoid); pelvic bones = ischium and pubis; calcaneus (heel bone); mandible
Sesamoid bones: develop in tendons where there is considerable pressure, tension or friction.
The cells that form compact bone are called
The axial skeleton / appendicular skeleton
The axial skeleton consists of ___ bones of the skull.
The 28 skull bones are separated into the ___ facial bones and the ___ bones of the cranium.
14 & 14
The facial bones are
2 nasal bones, 2 maxillary bones, 2 zygomatic bones, 1 mandible (the only moveable bone of the skull), 2 palatine bones, 1 vomer, 2 lacrimal bones & 2 inferior nasal conchae
Bones of the cranium
SINGLE occipital, frontal, ethmoid & sphenoid & the PAIRED parietal, temporal & ossicles of the ear (malleus, incus & stapes.
Single bones of the cranium
occipital, frontal, ethmoid & sphenoid
Paired bones of the cranium
parietal, temporal & ossicles of the ear (Malleus, incus & stapes).
Ossicle of the ear are
malleus, incus & stapes
The axial skeleton has how many bones in the vertebal column?
Bones of the vertebra are
The final portion of the axial skeleton consists of the bones of the
thorax, sternum & the 12 pairs of ribs.
How many ribs does the human skeleton have?
12 pairs totaling 24.
The appendicular skeleton
includes the girdles & the limbs.
The upper portion (of the append. skeleton) consists of the
pectoral or shoulder girdle, the clavicle, the scapula & the upper extremity (bones of the arm).
The bones of the arm are
humerus, the radius, ulna, the carpals (wrist bones), the metacarpals (bones of the hand) & phalanges (bones of the finger).
What are phalanges?
bones of the fingers
What are metacarpals?
bones of the hand
What are carpals?
bones of the wrist
Image of the hand bones
The appendicular skeleton includes the ________ girdle or os coxae.
Each of the os coxae consists of a
fused ilium, ischium & pubis.
Bones of the lower extremity include the
femur (thigh bone)
Thank you for viewing my note cards; please leave comments..I enjoy feedback. I got this information right out of the Hesi 2nd edition book I added a lot more info than the book offers. With these notes you won't need the Anatomy portion in the hesi book at ALL!! ;-)
Please add notecards of your own. We need Chemistry & Microbiology~
