What are the 4 main types of tissues |
Epithelial, Muscle, Connective, Nervous |
|
|
Epithelial tissues 2 |
squamous, columnar |
|
|
example of squamous tissue |
skin |
|
|
example of columnar tissue |
lining o lungs and digestive system |
|
|
description of epithelial tissues |
closely packed cells in one or more layers |
|
|
function of squamous tissue |
protection |
|
|
function of columar tissue |
protection and reduce friction (secrete mucus) |
|
|
Muscle tissues |
cardiac, smooth, skeletal |
|
|
cardiac tissue example |
heart |
|
|
smooth tissue example |
intestines |
|
|
skeletal tissue example |
biceps |
|
|
description of muscle tissue |
long bundles of cells (fibers) that shorten and lengthen |
|
|
cardiac tissue function |
involuntary and tireless movement |
|
|
smooth tissue unction |
involuntary movement |
|
|
skeletal tissue function |
voluntary movement |
|
|
connective tissues (4) |
bone, tendon, blood, fat (adipose) |
|
|
bone examples |
femur |
|
|
tendon example |
achilles |
|
|
blood example |
red blood cell |
|
|
fat (adipose) example |
under skin |
|
|
description of connective tissue |
cells surrounded by a matrix (matter in which specialized structures are embedded) |
|
|
Bone function |
support |
|
|
tendon function |
join muscle to bone |
|
|
blood function |
distribution of substances |
|
|
fat (adipose) function |
insulation and protection |
|
|
nervous tissue |
nerves |
|
|
nervous tissue description |
long, thin cells with branches that can conduct eleectrical impulses |
|
|
nervous tissue function |
sensory, communication, coordination |
|
|
How does epithelial tissue relate to function (6) |
thin flat multilayered easily replaced if/when damaged minimized damage to a few small cells rather than one large cell like body armor can shed cells easily if damaged |
|
|
How does muscle tissue relate to its function (5) |
long thin bundled together can contract and stretch to produce and allow for movement can have a few or many work together to increase from if needed |
|
|
how does nerve tissue relate to its function (3) |
long thin branched to allow for many connections and increase contact or communication with many cells at once |
|
|
how does connective tissue relate to its function |
various structures due to variety of function eg red blood cell - flat concave disks easily slide past one another |
|
|
why are squamous epithelial cells susceptible to cancer? |
they are exposed to the environment and contact more carcinogens |
|
|
why can adult stem cells be prone to becoming cancerous |
because there are more cells in mitosis, more errors may occur |
|
|
what possible affects could adult stem cells be prone to getting cancer cause |
metastasis - can infect other cells/healthy cells and spread through the blood |
|
|
general shape of a muscle cell |
long, narrow |
|
|
why are muscle cells shaped due to their function |
constantly contracts and extends |
|
|
why do red blood cells not have nuclei |
more hemoglobin and increased function do not divide, created in bone marrow |
|
|
why does skin not have nuclei |
do not divide due to exposure to the environment and damage |
|
|
which tissue forms membranes? |
connective |
|
|
which tissue allows for the movement of limbs and for organ movements within the body |
muscle |
|
|
which tissue uses electrochemical signals to carry out its function |
nerve |
|
|
which tissue supports and reinforces body organs |
connective |
|
|
which tissue may absorb and or secrete substances |
epithelial |
|
|
which tissue is the major controlling system of the body |
nervous |
|
|
which tissue has cells that shorten to exert force |
muscle |
|
|
which tissue forms endocrine (hormone) and exocrine (salivary, mucous) glands |
epithelial |
|
|
which tissue allows you to smile, grasp, swim, ski and throw a ball |
muscle |
|
|
which tissue surrounds and cushions body organs
|
connective |
|
|
which tissue forms the bone |
connective |
|
|
which tissue forms the brain and spinal cord |
nervous |
