define tissue
a group of cells of similar type that work together to serve a
common function
TERM 2
what are the four primary tissues?
DEFINITION 2
epithelial, connective, muscle , nervous
TERM 3
define epithelial
DEFINITION 3
covers the body surfaces ; lines cavities and organs; forms
glands
TERM 4
define connective tissue
DEFINITION 4
provides support and protection for organs; serves as a
storage for fat; participants in our immunity
TERM 5
define muscle tissue
DEFINITION 5
responsible for body movement; & fluids through the body
define nervous tissue
conducts nerve impulses through the body
TERM 7
what are the three basic shapes of epithelial
cells?
DEFINITION 7
squamous , cuboidal, columnar
TERM 8
define simple squamous epithelial
DEFINITION 8
flattened cells, allows for diffusion of materials and can
provide a slick surface to reduce friction ; lining of heart and
blood vessels, air sacs of lungs
TERM 9
define stratified squamous epithelial
DEFINITION 9
multiple layers of flattened cells, protection against abrasion,
infection, and drying out; lining of mouth esophagus and
vagina and outer layer of the skin
TERM 10
define simple cuboidal epithelial
DEFINITION 10
cube shaped cells; secretion, and absorption, kidney cells
define adipose tissue
under skin, around kidneys and heart ; stores energy ,
insulates , cushions organs (loose connective tissue)
TERM 17
define connective tissue
DEFINITION 17
tightly woven tissues, found in ligaments , tendons , and the
dermis (bone and muscle are attached)
TERM 18
define cartilage
DEFINITION 18
tough but flexible , serves as a cushion between bones ;
lacks blood vessels and nerves
TERM 19
what are the three types of flexibility?
DEFINITION 19
hyaline, elastic, fibrocartilage
TERM 20
what is hyaline cartilage?
DEFINITION 20
ends of long bones and parts of the ribs, nose, trachea,
bronchi, and larynx; support and flexibility; smooth surface
for joint movement
what is elastic cartilage?
flexible, elastic fibers, external ear and the epiglottis
TERM 22
what is fibrocartilage?
DEFINITION 22
withstand pressure, discs in the intervertebral spaces and the
knee joints
TERM 23
what is bone?
DEFINITION 23
supports and protects internal movements; facilitates
movement; stores lipids(in yellow marrow) , calcium , and
phosphorus , produces blood cells (in red marrow)
TERM 24
define skeletal muscle tissue
DEFINITION 24
obvious striations , multiple nuclei per cell
TERM 25
define voluntary
DEFINITION 25
attaches muscle to bones for voluntary movement of body
what are tight junctions?
leak proof seal; found between cell lining the urinary and
digestive tracts
TERM 32
what are adhesion junctions?
DEFINITION 32
allows for stretching of cells without coming apart; allows for
cells to slide slightly relative to each other , found between
skin cells
TERM 33
what are gap junctions?
DEFINITION 33
have small holes connecting the cytoplasma of adjacent cells
; allow for exchange of ions between cells ; rapid
communication of electrical impulses in cardiac cells
synchronizing electrical activity thus contraction; found
between cardiac muscle cells
TERM 34
define membrane
DEFINITION 34
sheets of empithelium supported by connective tissues
TERM 35
the four types of tissues
DEFINITION 35
mucous, serous, synovial, cutaneous(skin)
define ventral cavity
thoracic cavity, abdominal cavity, the diaphragm separates
them; anterior; front of body
TERM 37
define dorsal cavity
DEFINITION 37
cranial cavity(encloses the brain), spinal cavity (houses the
spinal cord) posterior back of body
TERM 38
what are the A B C D signs of malignant and
melanoma?
DEFINITION 38
A- asymentry ; B= border irregularity ; C= color variation ;
D= diameter larger than a pencil
