What type of muscles are in the uterine wall?
Uterine muscle cells help make up the myometrium, which is the inner layer of the uterine wall. These muscle cells aid in inducing uterine contractions. They support stromal and vascular tissue as well.
What is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
State the function of the hormones oxytocin?
Dunno what it does in males (if anything). In females, it stimulates lactation, mostly. If given artificially, it can stimulate contraction of the uterus and parturition (doctors use it to induce labor). But it isn't really clear if the pituitary secretes oxytocin on its own to stimulate labor, or if there is some other mechanism that induces labor.
Explain Chemical changes during muscular contractions?
The chemical changes during muscular contractions include conversion of ATP into ADP, break-down of phosphocreatine and muscle glycogen, formation of Fructose diphosphate and lactic acid and resynthesis of creatine phosphate.
What type of muscle can hold prolonged but slow contractions?
Smooth muscle is the type of muscle that can hold prolonged but slow contractions. It is found in the walls of hollow organs, such as the intestines and blood vessels, and operates involuntarily. Smooth muscle contractions are sustained for longer periods compared to skeletal muscle, allowing for functions like the continuous movement of food through the digestive tract.
What neurotransmitter stimulates skeletal muscle contractions?
Acetylcholine
What nutrient is not digested but stimulates intestinal muscle contractions?
The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
What stimulates intestinal muscle contractions?
Nicotien or anything chemical which stimulates the Nicotinic receptors.
From oxytocin and prostagladins which increase uterine muscle contraction?
Oxytocin stimulates the uterine muscles to contract and also increases the production of prostaglandins, which increase the contractions further. Manufactured oxytocin is sometimes given to induce labour if it has not started naturally or it can be used to strengthen contractions to aid childbirth.
What type of muscles are in the uterine wall?
Uterine muscle cells help make up the myometrium, which is the inner layer of the uterine wall. These muscle cells aid in inducing uterine contractions. They support stromal and vascular tissue as well.
What muscle actions would be classified as isotonic contractions?
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
Do muscle contractions cause menstrual cramps?
No, not quite.Prostaglandins are produced which cause the uterine contractions to push out menstrual flow, in a healthy woman this should not be painful. It's when the prostagladins are overproduced that menstrual cramps occur as these cause blood vessels to contract so cut off oxygen to the muscle.
What are the differences between isometric, concentric, and eccentric muscle contractions?
Isometric muscle contractions happen when the muscle stays the same length, concentric contractions occur when the muscle shortens, and eccentric contractions occur when the muscle lengthens.
Which muscle can undergo hyperplasia?
Uterine smooth muscle
Why does eccentric produce more force than concentric?
Eccentric muscle contractions involve the lengthening of the muscle under tension, which allows for greater force production compared to concentric contractions where the muscle shortens. This occurs because the muscle fibers can generate more force during the controlled lengthening process in eccentric contractions, leading to greater tension development.
Are isotonic contractions often preceded by isometric contractions?
Isotonic contractions can be preceded by isometric contractions, especially during activities that require a gradual increase in muscle tension before movement occurs. In isometric contractions, muscles generate tension without changing length, which can stabilize joints and prepare the muscles for subsequent isotonic contractions, where the muscle shortens or lengthens while maintaining tension. However, isotonic contractions can also occur independently, depending on the specific movement and muscle activation patterns involved.
What does the mitochondria do in muscle cell?
Mitochondria in muscle cells produce energy through a process called cellular respiration, generating ATP (adenosine triphosphate) that fuels muscle contractions. This energy production enables muscle cells to sustain prolonged contractions during physical activities.
