blanks with the words connective tissue or
epithelial tissue.
A. The connective tissue consists
of many cells with little intercellular substance.
B.
The epithelium tissue
is penetrated by blood vessels.
C. Connective
tissue does not cover body surfaces or line passageways and cavities, but is more
internally
located; it binds, supports, and protects.
D. Rewrite these sentences and fill in the
blanks with the connective tissue
types elastic, fibrous, or hyaline.
A.
Fibrous tissue is found where strength and rigidity are needed, as in discs between
vertebrae and the symphysis
pubis
B.
Hyaline is the white, glossy cartilage covering ends of bones (articular),
covering ends of ribs (costal),
and giving
strength to nose, larynx, and trachea.
C.
Elastic tissue provides strength and flexibility, as in external part of the ear.
E. Rewrite these sentences and fill in the
blanks with the muscle tissue types cardiac,
smooth, or skeletal.
A.
The cardiac muscle tissue
forms the walls of the heart.
B. The skeletal muscle tissue
is attached to the bone
C. Smooth muscle tissue has spindle shaped cells and is tapered at the end.
D. Cardiac muscle tissue contains
intercalated discs and gap junctions.
E. Smooth muscle tissue is found in
walls of intestine, urinary bladder, and blood vessels.
F.
Skeletal muscle tissue
cells are multinucleate.

C. Your
Personal Bones
I
chose the rib cage to write about that I have some experience with. The rib
cage surrounds the vital organs such as the heart and lungs. There are twelve
ribs on each side. I studied this in science class in grade school. Also I
experience my 9th ribs on the right side frequently slipping out of
place.
On the
top of the rib cage is the clavicle that joins the ribs to the shoulder.
In the center of the rib cage connecting the two sides is the sternum.
Going out from the sternum is the false ribs that connect to the true
ribs. At the bottom of the rib cage not even connected to it are two floating
ribs.
For the bone structure
that I wanted to explore I chose the foot. The foot has many bones that enable
it to be flexible. At the back of the
foot moving forward there is the calcaneus that makes up the heel. The
bone on top of the calcaneus is the talus these both carry most of the
weight of the foot. Moving forward is the cuboid bone this is connected
to the calcaneus it is barely underneath the talus. On top of the cuboid bone
is the navicular bone it connected to the talus. In front the navicular
bone are the cuneiform bones; then comes the metatarsophalangeal
bones and finally the phalanges that make up the toes.
