Muscular System

One theory states that long ago, when men were covered by much more hair than they are today, the erector pili muscles caused the hair to stand up when the body became chilled. The hairs would bunch together and protect the skin from cold, harsh weather.

While you are asleep, your body primarily relies on smooth muscles and cardiac muscles. Smooth muscles are responsible for involuntary functions such as digestion and blood vessel regulation, while cardiac muscles maintain the heartbeat. Additionally, skeletal muscles may experience some activity during REM sleep due to dreaming, but they are generally relaxed to prevent acting out dreams. Overall, most muscle activity during sleep is involuntary and essential for maintaining bodily functions.

Each of the individual muscle fibers in the muscle are contracted when the maximal stimulus is achieved. Dr. H.

A prime mover is the muscle that has the most influence in one direction on the joint it acts on. For example the prime mover in extension of the forearm is the triceps.

Initial treatment predicates an understanding of basic resuscitation. Airway assessment and stabilization is essential for all patients. Supplemental oxygen may be required, and the airway must be repeatedly reassessed, especially if the patient's mental status or vital signs decline.

An intravenous (IV) line should be established, and fluid repletion with normal saline may be initiated if the patient exhibits tachycardia, hypotension, or other signs of poor tissue perfusion (eg, poor capillary refill, cool extremities). Vital signs and cardiac rhythm must be monitored closely because acidosis predisposes to dysrhythmias including tachydysrhythmias and fibrillation.

Established prehospital treatment protocols should be followed, and nonprotocol medications, such as sodium bicarbonate, should be administered only in conjunction with medical control. Transport all patients to the appropriate emergency facility for further management.

EMERGENCY DEPARTMENT CARE

Lactic acidosis is typically associated with tissue hypoperfusion and states of acute circulatory failure. Treatment of lactic acidosis requires identification of the primary illness and directed therapy.

Restoration of tissue oxygen delivery, thereby causing cessation of acid production, remains the primary therapeutic focus. Goal-directed therapy for sepsis is well described and is associated with improved outcomes. Appropriate measures include treatment of shock, restoration of circulating fluid volume, improved cardiac function, identification of sepsis source and appropriate therapy, and resection of any potential ischemic regions.

CONTINUING CARE

In addition to general supportive measures, treatments must be directed at correction of the underlying disorder and may include the administration of appropriate antibiotics, surgical drainage or debridement, chemotherapy for malignancy, discontinuation of potentially causative medications, and dietary modification in inborn errors of metabolism.

PROCEDURES

Aside from resuscitation measures including adequate intravenous access and airway stabilization in all potentially ill patients, hemoperfusion or hemodialysis may be indicated in association with ethylene glycol and methanol poisoning. Dialysis may also be useful when severe lactic acidosis exists in the setting of renal failure or congestive heart failure and additionally with metformin intoxication.

The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.

Skeletal muscles have an 'origin' which is where the muscle starts at and an insertion. For example, the biceps origin is at the shoulder. It's insertion point is the tendon where it attaches to the radius and ulna.

There are also smooth muscles that line the bodies organs and blood vessels.

There is the heart muscle made of cardiac muscle tissue.

skeletal muscles are defined as attached to the bones of the skeleton and make body movement possible. they are also known as striated muscles and they are voluntary muscles, meaning you can control any movement.

It is basically how your body works

It depends on weight and how often you do the curls. If you want size you should be using heavy weights that make it so you have to stop on your eighth or ninth rep. For lean muscle, you want lighter weight and more reps.

Soft is the relaxed form of a muscle. Usually a muscle will get softer if not used for much time. It can also dissolve much faster as body will try to get rid of anything unnecessary or more than needed.

Potassium is the element that is required for normal nerve and muscle function. Bananas are high in potassium and so are broccoli, tomatoes and sweet potatoes.

The posterior deltoid is one extensor of the upper arm.

I believe you are speaking of your lymph node if it hurts and is swollen you may have an infection and need to see a doctor. Most of the time when you have a sinus infection, cold, flu, strep throat etc... the lymph nodes will swell up causing pain. I would suggest seeing a doc for treatment.

The primary function of the biceps muscles is elbow flexion or mowing your arm towards the shoulder. It's secondary function is hand/arm supination, which is the movement of your hand from facing downward to facing upwards.

On the other hand, the triceps' primary function is to straighten the arm or extending the elbow. The triceps' muscles also helps in the movement of the arm towards the body or moving your arm from out to inside or towards the mid line of your body which is called adduction. this secondary function is performed together with the muscle Latissimus Dorsi.

The quadriceps is one of the large muscles in your thigh, so any sport that involves a lot of running would be good for using your quadriceps. Examples would include track and field events, football (soccer or American football or Aussie Rules), rugby, etc.

Cardiorespiratory fitness is the ability of the respiratory systems to efficiently transfer oxygen and nutrients to skeletal muscles.

Proper rings are only formed by smooth mucle and are called sphincters. NB not all sphoncters are proper ring.

they relate because they dont move. ivoluntary muscle means that they dont move. the smooth muscle doesnt move at all only the skeletal muscle does.

Cardiac muscles move your organs. they are the ones that are uncontrollable...

Tendons connect muscles to bone.

It does not necessarily help to reduce weight but it does train the abdominal muscles to sit in a particular position, therefore holding in the stomach area and giving the illusion of a flatter stomach and therefore loss of weight.
