Transcript Body Tissues

 Set
up your tabs in your binder
 Who
has something in common with you
PHYSICALLY… Something about the two
of you is very TWIN-LIKE.
 You
will summarize your concept map in
a paper that DESCRIBES tissue.
 There
are four major types of tissue
found in humans, including epithelial,
connective, muscle and nerve tissues.
Epithelial tissue can be broken down into
several types, such as simple squamous
and simple cuboidal tissues. This type of
tissue is known for lining many organs. It
even lines the entire body, since our skin
consists of epithelial tissue.
 Tissues
are groups of cells that are
similar in structure that work together to
perform a specific function.
 There are four main tissue types:
• Epithelium
• Connective tissue
• Muscle
• Nervous tissue
 Epithelium,
or epithelial tissue, forms
the linings, coverings, and glandular
tissue of the body.
• One type of epithelium forms the outer layer of
the skin
• Another type of epithelium lines the air sacs of
the lungs
 Cells
in epithelium are packed tightly
together to form continuous sheets
 Connective
tissue protects, supports, and binds
together other body tissues.
 Connective tissue is made up of different types
of cells in varying amounts of a nonliving
substance around the cells, called the matrix.
 Examples of connective tissue include:
• Bone
• Cartilage
• Adipose tissue (fat)
• Blood


Connective
tissue which is
found mixed
around acini of
mucus secreting
glands. In this
region collagen and
reticular fibers
which stain blue
in this
preparation.
Also connective
tissue cells such
as fibroblasts,
mast cells and
plasma cells
within the
connective
tissue.
 Muscle
tissue is specialized to contract
and cause movement.
 There are three main types of muscle
tissue:
• Skeletal muscle
• Cardiac muscle
• Smooth muscle
 Can
you guess the location and function
of each muscle type?
 Nervous
tissue is composed of specialized cells
called neurons that receive and send electrical
signals in the body.
 Nervous tissue responds to stimuli and
transmits impulses and together with
supporting cells, makes up the brain, spinal
cord, and nerves.
 Use
describe language to summarize
what you learned.
 The graphic organizer uses the phrases
“such as” and “found in”. What other
descriptive phrases can use in your
summary? How will you make your
writing sound more sophisticated?

Use the skull anatomy tutorial presented by GateWay Community College
at http://www.gwc.maricopa.edu/class/bio201/skull/skulltt.htm to
identify the following bones of the skull. Mark these bones on your
Maniken® and on the skeletal system organizer.
Mandible
Maxilla
Zygomatic Process
Frontal Bone
Temporal Bone
Occipital Bone
Parietal Bone

Use the tutorial of the head and neck muscles presented by GateWay
Community College at
http://www.gwc.maricopa.edu/class/bio201/head/head1.htm and
other Internet sources to find the location of the following muscles.
Orbicularis Oculi
Orbicularis Oris
Temporalis
In your laboratory journal, take notes on the basic function or action of
each muscle.
Obtain another copy of the body system graphic organizer (skeletal
view).
Sketch the muscles you researched in Step 12 in pencil on the organizer.
Label the top of the diagram “Muscular System.” Label each muscle you
add to the diagram. Make sure to add a brief statement of function.
Alternatively, you can create a key on a separate sheet of paper.
