Braxton Hicks contractions

fibers called myofibers. These fibers are themselves composed of myofibrils, which are comprised of the ordered arrangement of actin and myosin. These proteins slide past each other in the presence of calcium ions (Ca2+) and ATP resulting in muscle contraction and relaxation (See Figure). The skeletal muscle motor unit consists of a motor neuron and the muscle fibers innervated by the neurons axon terminals. When an action potential reaches the end of the motor…

Concentric contraction is when the muscle gets shorter when you flex your arms for example when you lift a weight/dumbbell towards your body that is a concentric contraction. These are the most common types of occurs in your body as it occurs in most day to day activities. Another example of this is the quadriceps when you do a squat movement when you get down to the bottom is the concentric contraction. Eccentric contraction is where the muscle lengthens when muscle moves so this is the…

muscles are typically found within walls of blood vessels. Smooth muscles can be found in the urinary tract and in lymphatic vessels. The structure, function, and the contractions of the smooth muscles are very different from cardiac and skeletal muscles (e.g., structure non-striated, function moves fluids throughout body, contractions of the muscle constrict.) Smooth muscles are single unit varieties because the whole muscle either contracts or…

by the contraction of the muscle will vary on the length of the muscles at rest. The beginning and end of a contraction will be considered a weak-contraction or too stretched which means the myosin is to close to the Z-discs or the myosin overlaps which does not allow a correct cross-bridge to occur. When the contraction is at regular resting length will produce the greatest force when muscles contract.…

We have over 600 muscles in our bodies that perform a variety of functions. All muscles are made of the same tissue but within our bodies there are 3 different kinds of muscles. There are Cardiac, smooth, and skeletal muscles and each of these is found in different places. Cardiac muscles are in the walls of the heart, Smooth muscles are in the walls of organs, and skeletal muscles are attached to our skeletons. Cardiac and smooth muscles are involuntary used whereas skeletal muscles are…

Premature Ventricular Contractions (Pvcs) Overview- Premature ventricular contractions (PVCs) are abnormal, extra heart-rates that initiate in ventricles, one of your heart's two lower pumping chambers. These additional pulsates disturb your normal heart musicality, in some cases making you feel a flip-flop or skipped beat in your chest. Premature ventricular contractions are extremely normal, mainly it occurs in most of the people at some time. If you are infected by ventricular constrictions,…

after childbirth. Many women start to experience Braxton Hicks contractions in week 23. These random contractions are felt on the top of the uterus and are painless. You may be able to feel them if you place your hands on your tummy. Braxton Hicks contractions usually last for 30 to 60 seconds. You will notice the frequency of such contractions increasing in the weeks to come. It is nature’s way of preparing your body for the actual labor contractions. Changes happening to your baby in week 23…

Stages of Childbirth Childbirth has three stages it progresses through. The first stage, or the beginning of childbirth, begins with effacing and dilating. Dilating is the opening of the cervix. Effacement is the thinning of the cervix to prepare for birth. (1) This is what causes the most pain during childbirth. It is also the longest stage, lasting anywhere from an hour to over a day. To prepare for childbirth doctors may perform an episiotomy, which is a small incision to avoid vaginal…

trimester and can often last for days or weeks on end. It is often defined as ‘false labor’, however, in reality, prodromal labor is an early stage of labor. Contractions during prodromal labor can increase in frequency and severity, similar to ‘true labor’, but they tend to not be regular and consistent. Unlike Braxton Hicks contractions, which can often be lightened with a cool glass of water and putting your feet up, prodromal labor can be exhausting both emotionally and physically. It is…
