How does connective tissue differ from the other three major tissue types? |
Connective tissue often consists of relatively few cells embedded in an extracellular matrix. |
Which of these describes loose connective tissue? |
It is a loose weave of fibers that functions as a packing material. |
Cartilage is found _____. |
at the ends of bones such as the femur |
_____ is the connective tissue specialized for transport. |
Blood |
What type of epithelium would you expect to find covering a surface subject to physical forces? |
stratified epithelium |
What type of epithelial tissue, found in the intestines, absorbs nutrients? |
simple columnar epithelium |
Which of these tissues, found in the lungs, permits gas exchange by diffusion? |
simple squamous epithelium |
What type of epithelial tissue lines kidney tubules? |
simple cuboidal cells |
What type of muscle is responsible for contractions of the digestive tract and arteries? |
smooth muscle |
Cardiac muscle is the only muscle composed of _____ fibers. |
branched |
_____ muscle is attached to bones. |
Skeletal |
A neuron consists of _____. |
A neuron consists of _____. |
Nervous tissue functions _____. |
to sense stimuli |
Which of the following is a correct statement about an organism and its environment? Animals isolated from their environments live longer than those exchanging matter with the environment. |
The interstitial fluid is the exchange medium between body cells and the circulatory system in vertebrate animals. |
The four major categories of tissues are _____. |
nervous, epithelial, connective, and muscle |
Penguins, seals, and tuna have body forms that permit rapid swimming, because |
the shape is a convergent evolutionary solution to the need to reduce drag while swimming |
As body size increases in animals, |
there is a decrease in the surface-to-volume ratio. |
Most of the exchange surfaces of multicellular animals are lined with |
epithelial tissue. |
An example of a connective tissue is the |
blood |
Stratified cuboidal epithelium is composed of |
several layers of boxlike cells. |
Connective tissues typically have |
relatively few cells and a large amount of extracellular matrix. |
The nourishment, insulation, and support for neurons is the result of activity by the |
glial cells. |
Fibroblasts secrete |
proteins for connective fibers. |
Blood is best classified as connective tissue because |
its cells are separated from each other by an extracellular matrix. |
Muscles are joined to bones by |
tendons |
With its abundance of collagenous fibers, cartilage is an example of |
connective tissue. |
In a typical nerve cell, the nucleus is found in the |
cell body. |
All types of muscle tissue have |
interactions between actin and myosin. |
All skeletal muscle fibers are both |
striated and under voluntary control. |
Food moves along the digestive tract as the result of contractions by |
smooth muscle. |
The type of muscle tissue surrounding internal organs, other than the heart, is |
smooth muscle. |
The body tissue that consists largely of material located outside of cells is |
connective tissue. |
