Muscle and Cross Section Cells
Before submitting your written response, check that: It compares three specific muscles in the human body that vary in muscle tissue type in terms of: Presence or absence of striations (5 points) Size, shape, and arrangement of fibers (5 points) Function/s resulting from the muscle contraction (5 points) Relationship of muscle cell properties to muscle function (10 points) The table is clear, well-organized, written in complete sentences, correct language use, etc. (0 to 5 points) Slides: Are there striations across the width of the muscle cells?
Number of Nuclei? What are the size, shape, and arrangement of fibers? What function occurs as a result of the contractions in the selected muscle? (see page 3 of the lesson) What is the relationship between structure and function in the selected muscle? (see page 3 of the lesson) Muscle – Human Cardiac Yes, there are striations across the width of the Human Cardiac Muscle cells. There is one nucleus. The fibers are striated and branched with the single nucleus. The sizes of the fibers are quite large, actually.
Muscle and Cross Section Cells Essay Example
As a result of the contractions in the Human Cardiac Muscle cells, it keeps your heart beating. A good thing about this is, the tissue can be controlled involuntary therefore you do not have to worry about the way your heart beats. The relationship between the structure and function of the Human Cardiac Muscle cells is, in the structure, the fibers are branched together connected to the single nucleus, while the function of the tissue is to pump blood throughout the whole body. Intestines – Outer Wall Detail(smooth muscle)
No, there are no striations across the width of the Outer Intestine Wall cells. There is one nucleus. The fibers are not striated, and the fibers are short. The sizes of the fibers are quite small; smaller than the skeletal cells in fact. As a result of the contractions in the Outer Wall Intestine cells, it allows your muscles to move without thought. Meaning, you do not have to actually consciously think about each way your muscles move. In turn, this result in the allowance of the muscles to contract is involuntary and requires no thought.
The relationship between the structure and function of the Outer Wall Intestine cells is, in the structure, the fibers are short and not striated, while since the cells are “smooth cells” this allows the function of the cells to be involuntary and is composed in the lining of the organ. The contractions of the cells allow the organ to keep blood, fluids, and necessary nutrients to flow throughout the organ. Slide 1:Muscle- Skeletal Longitudinal Section and Slide 2:Muscle-Skeletal Cross Section
Yes, there are multiple striations across the width of the Muscle-Skeletal Longitudinal Section of the cells and the Muscle-Skeletal Cross Section cells. There are several nuclei in both cells. The fibers in both cells are striated, and the fibers are long and each muscle cell is fused to one another. This is why so many nuclei are included. Also, the fibers are almost threadlike, with dark and light colored striations. As a result of the contractions in the Muscle- Skeletal Longitudinal Section cells and the Muscle- Skeletal Cross Section cells, it allows your muscle to be able to contract in response to nerve stimuli.
This means that the movements of most of these muscles are not involuntary, you can control them. Therefore, once the stimulation stops, the muscles relax. The relationship between the structure and the function of the Muscle-Skeletal Longitudinal Section and the Muscle-Skeletal Cross Section cells is, in the structure, the cells are striated and elongated like a threadlike structure, also fused together with other muscle cells explaining the multiple nuclei. While the function of the muscle cells is to voluntary move muscles in your body. This is the caused by the control of your actions that cause your muscles to “move” essentially.
