100

The skeletal system has 4 components

cartilage, bones, ligaments, tendons

100

cartilage is

avascular

100

bone is what tissue

connective tissue

100
where two or more bones meet

articulation

100

epidermis is composed of

stratified squamous keritanized squamous epithelial tissue

200

functions of skeletal system

support

protection

movement

storage

blood cell production

200

what type of tissue

connective

200

bone contains three types of cells; what are their functions

osteoblasts: make bone

osteocytes: maintain bone

osteoclasts: break down bone

200

three types of functional classifications

synarthrosis

diarthrosis

amphiarthrosis

200

two types of cells located in the epidermis

keratinocytes: produce keratin

melanocytes: produce melanin; found in the stratum basale

300

types of bones

short, long, flat, irregular

300

functions of the three types of cartilage

hyaline: provide smooth surfaces for joints and support

fibro: support

elastic: support with flexibility

300

cell body of osteocytes sit in:

cell processes of osteocytes sit in:

cb: lacunae

cp: canaliculi

300

cartilagenous joints are united:

synovial joints are seperated by:

bones are united by a plate of cartilage

separated by a fluid filled joint cavity 

300

epidermis has two types of skin

thick: palms, finger tips, soles of feet

thin: everywhere else

400

spongy bone has no:

spongy bone is composed of:

no osteons present; composed of trabeculae

400

three types of cartilage

hyaline, fibrocartilage, and elastic

400

extracellular matrix is composed of

osteoids and hydroxyapatites

400

two types of joint capsules

fibrous capsule: outer layer of joint capsule

synovial membrane: lines the inside of the fibrous capsule

400

dermis is made up of two layers

papillary layer

reticular layer

500

major structure of long bones

diaphysis

epiphysis

ephysial lines

periosteum

endosteum

500

found where

hyaline:

elastic:

fibro:

h: end of long bones; ribs

e: external ear; epiglotis

f: pubic symphysis, labrum


500

osteoid and hydroapities are what

hydro: account for hardness of bone

osteoids: secreted by osteoblasts and give bones strength

500

ligaments of the knee

patellar ligament

medical collateral ligament

lateral collateral ligament

anterior cruciate ligament

posterior cruciate ligament

500

layers of the epidermis

stratum corneum

stratum lucidum

stratum granulosum

stratum spinosum

stratum basale
