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 hormone stimulates smooth muscle contraction?
Oxytocin is a hormone that stimulates smooth muscle contraction, particularly in the uterus during childbirth and in the mammary glands during breastfeeding. It is produced in the hypothalamus and released by the posterior pituitary gland. Additionally, other hormones like prostaglandins also play a role in promoting smooth muscle contractions in various physiological processes.
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.
The muscle lengthens during?
The muscle lengthens during a process called eccentric contraction. In this type of contraction, the muscle generates force while being elongated, such as when lowering a weight or during the downward phase of a squat. Eccentric contractions are important for activities that require controlled movement and help to build muscle strength and stability.
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.
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 stimulates intestinal muscle contractions?
Nicotien or anything chemical which stimulates the Nicotinic receptors.

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 does the non pregnant uterine wall mostly consist of?
The non-pregnant uterine wall primarily consists of three layers: the endometrium, myometrium, and perimetrium. The endometrium is the inner lining that undergoes cyclical changes during the menstrual cycle. The myometrium is the thick middle layer composed of smooth muscle, responsible for uterine contractions. The perimetrium is the outer layer that provides structural support.
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.
