C Caveolae replace sarcomere formation. Both actin and myosin are important components of the smooth muscle contractile apparatus much like that of skeletal muscle and cardiac muscle but these do not play a role in calcium sensitivity.
Smooth Muscle Anatomy And Physiology
With muscular dystrophy ________.
. Termed unitary smooth muscle or visceral muscle this type of smooth muscle is the most common observed in the human body forming the walls of hollow organs. Simplesquamous epithelia consist of tall narrow cellsSimple epithelia form impermeable barriers to viruses. These nuclei are found near the center of the cardiac muscle cells.
The muscular system is composed of two different types of muscles. The muscular system is composed of two different types of muscles. View the full answer.
B muscles decrease in size due to loss of fat and connective tissue. O a dephosphorylation of myosin light. Decreased ATP levels would be expected to decrease the ability of calcium levels.
Skeletal muscles which are made of fibers nerves and blood vessels contract in order to make the body move. Based on your observations of skeletal muscle tissue which of the following describes characteristics of skeletal muscle tissue. Select the statement that best describes stem cells.
ATP is required for smooth muscle contraction. They have a rapid onset of contractions. Check out a sample textbook solution See solution Expert Solution Answer Want to see the full answer.
Smooth muscle cells are elastic not striated spindle-shaped and contain a single central nucleus. Stratified squamous epithelia are present where protection from abrasion is important. They cannot exhibit tetanus.
After the action potential When a smooth muscle cell is stimulated to contract what initiates crossbridge cycling inside the cell. A They exhibit spontaneous action potentials. They primarily use anaerobic metabolism.
The answer is a one or two. D Smooth muscle cells have well-developed sarcoplasmic reticulum. During the action potential O d.
They cannot exhibit tetanus. The muscular system is responsible for controlling the actions of smooth and cardiac muscles. A Critical Thinking Questions Why can smooth muscles contract over a wider range of resting lengths than skeletal and cardiac muscle.
Which statement BEST describes how the body moves. Chapter 9 Muscles and Muscle Tissue TB Home. D They depend upon recruitment using the autonomic nervous system.
B They consist of muscle fibers that are structurally independent of each other. The muscular system is composed of muscles tendons and ligaments. D most cases appear in young females.
Once destroyed they are replaced with fibrous scar tissue. -parenchyma of solid organs liver and kidney smooth muscle cells vascular endothelial cells and firbroblasts. The muscular system is responsible for controlling the actions of smooth and cardiac muscles.
They are resistant to fatigue. Which of the following describes the cells of unitary smooth muscle. Which of the following statements describes smooth muscle cells.
AAll muscle action is voluntary or able to be consciously controlled. They have a rapid onset of contractions. Cardiac muscle cells like skeletal muscle cells are made up of sarcomeres that contain actin and myosin filaments which create the dark and light bands called.
The muscular system is composed of muscles tendons and ligaments. Cardiac muscle cells have striations. They have a rapid onset of contractions.
B A calcium-calmodulin complex initiates cross-bridge formation. Which of the following statements describes smooth muscle cells. There are 5 main characteristics of muscle.
Tap card to see. CMuscles always work independently to move parts of the body. Smooth muscle cells are arranged together in sheets and this organisation means that they can contract simultaneously.
Which statement best describes smooth muscle. A most forms do not appear to be inherited. Select the statement that accurately describes the muscular system.
Smooth muscle is composed of sheets or strands of smooth muscle cells. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells. Before the action potential c.
Want to see the full answer. They are resistant to fatigue. Click card to see definition.
A cardiac muscle cell contracts. They primarily use anaerobic metabolism. C muscle fibers degenerate and atrophy.
Which characteristic refers to a muscles ability to react to chemical signals stretch and electrical signals across a plasma membrane. Biology questions and answers. These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins.
The fibers are not striated and cells are indistinguishable from each other. A cells that do not normally divide. Cardiac muscle cells contract autonomously and involuntarily.
Smooth muscles which are made of blood vessels fibers and. Select the statement that accurately describes the muscular system. They are resistant to fatigue.
After the action potential and after the latent period b. The answer is a true. They cannot exhibit tetanus.
They have poorly developed sarcoplasmic reticulums and do not contain T-tubules due to the restricted size of the cells. Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. The fibers are striated and each cell has a single nucleus.
Which of the following statements describes smooth muscle cells. Pseudostratified epithelia consist of at least two layers of cells stacked on top of one another. A Smooth muscle contains the same proteins as cardiac and skeletal muscle.
Single-unit smooth muscle produces slow steady. C They are used for vision and hair raising. BThe three types of muscle tissue are skeletal muscle smooth muscle and involuntary muscle.
Cardiac and smooth muscles are made of muscle fibers nerves and cartilage and are responsible for all movement in the body. They primarily use anaerobic metabolism. Each cell is a spindle-shaped fiber and contains a single nucleus.
Select the correct statement regarding epithelia. No striations are evident because the actin and myosin filaments do not align in the cytoplasm. The cells are interconnected physically and electrochemically to act as a syncytium.
Smooth muscle is involuntary.
