How does the smooth muscle cell function? How could the structure and function of the cell be used to support evolutionary theory? Why is blood classified as connective tissue? In what kind of cells can you find peroxisomes, and how many are in each cell?
How does a skeletal muscle return to its starting length after a contraction? Describe how connective tissue is part of a skeletal muscle. What is the difference between fascia and fascicle of muscle? What is the relationship between the structure and function of the ca...
There are over 600 muscles in your body. They make up over 40 percent of your weight and function in several different capacities. Several thousand small fibers make up every muscle. They aid in everything from lifting a heavy book bag to pumping blood to every part of your body. Some mu...

While fibrous scar tissue is important to support healed tissue early on, its presence later in the process of healing can have a negative effect on muscle function. Scar tissue is fibrous and dense, so it doesn’t stretch and contract like healthy muscle fibers. That means movement and stret...
What is the primary function of the arrector pili muscle? The arrector pili muscle is a tiny muscle connected to each hair follicle and the skin. When itcontracts it causes the hair to stand erect, and a "goosebump" forms on the skin. The hair follicle is a tube-shaped sheath that sur...
mucosal tissueis underpinned by a layer of connective vaginal tissue which work together to produce mucus for a type of vaginal discharge called lubrication. Beneath these is a layer of smooth muscle, which can contract and expand, followed by another layer of connective tissue known as the...
The upper part of the cervix consists mainly of smooth muscle fibers. The lower part is built up of the fibrous connective tissue. The cervix produces mucus that helps carry sperm from the vagina to the uterus, where it can fertilize an egg if the woman is ovulating. When the woman isn...
The airways that bring air into the lungs (the trachea and bronchi) are made of smooth muscle and cartilage, allowing the airways to constrict and expand. The lungs and airways bring in fresh, oxygen-enriched air and get rid of waste carbon dioxide made by your cells. They also help in ...
Describe how acetylcholine, calcium, and ATP are involved in the process of muscle contraction. Explain the smooth graded contraction in skeletal muscle. How does muscle fiber structure relate to muscle contraction? Describe the structure and function of a muscle fiber; summarize the ...
