Muscular System

They should eat more protein and more often and exercise frenquently.

1) Exercise with high rep sets (50-100 reps per set) so your muscles change from the high power to low power type of fiber.

2) Do routine, light jogging for several months. Three times a week, start by doing 20 min. on the treadmill. Then when you build endurance, do an hour on the treadmill (three or four times a week). 3) Eat as little protein as you can. Your body will make up for it by eating your muscles

4) Do this until you get the body you want.

Smooth muscle tissue is able to maintain an even amount of tension for periods of times. This is helpful in its function of expelling the contents of an organ.

The connective tissue itself is called Fascia. It not only surrounds muscles and tendons but also organs, nerves and bones--it basically ties the human body together.

There are three types of fascia which surround muscles. They are named for how 'deep' they are and how much of a muscle they surround. They are:

Endomysium, which surrounds ONE muscle fiber

Perimysium, which surrounds a BUNDLE of muscle fibers

and Epimysium, a sheet of fascia which covers the ENTIRE muscle.

Nerves are also covered with fascia, and the naming scheme for that fascia is similar.

A muscle fiber is made of many contractile units called sarcomeres.

Strap-like muscle that is a weak thigh flexor known as the tailor's muscle is called Sartorius. This is the muscle that connects to the hamstring.

The cardiac muscle cell is self stimulating and will beat.

If peristalsis were to stop, the movement of food through the gastrointestinal tract would be most directly affected. Peristalsis are muscle contractions that take place in the digestive tract.

Orbicularis oculi is a wide flat muscle that encircles the eye.

Cardiac tamponade is a condition caused by rapid buildup of fluid (usually blood, but some conditions cause other fluids to collect) in the pericardial sac (see question below for definition of pericardium).

Small amounts of fluid or fluid that accumulates over a long period of time does not cause problems, but when the fluid volume becomes too high or it accumulates rapidly, the pressure within the pericardium rises and may eventually lead to compression of the cardiac chambers, restricting filling and emptying. This is most prominent in the right sided chambers, specifically the right atrium and ventricle. Restriction of filling results in a decrease in cardiac output and eventually hypotension, shock, and (if uncorrected) death. This is a not uncommon cause of PEA (pulseless electrical activity) in traumatically injured patients.

Signs and symptoms of cardiac tamponade include the classic signs of hypotension/shock, jugular venous distention and muffled heart sounds. Together, these signs bear the eponym "Beck's triad." Not all patients with cardiac tamponade will have all of these signs, however. Clinical suspicion in the appropriate setting still plays a major role in diagnosis. Other signs include those caused by these three core signs - altered mental status, weak or absent peripheral pulses, cyanosis, respiratory distress or failure, diaphoresis, tachycardia as the heart tries to compensate for a decreased output and hypotension, decreased urine output, and others.

Diagnosis of cardiac tamponade is done either on appropriate clinical suspicion in appropriate patients and physical exam or by ultrasound at the bedside. Rapid bedside ultrasound will reveal a large pericardial effusion with compression of the R heart structures, particularly in diastole. This is diagnostic of cardiac tamponade.

Treatment includes pericardiocentesis at bedside, either blindly or ultrasound guided or emergent pericardial window in the OR. In traumatic cases, particularly penetrating trauma, the cause is an atrial or ventricular injury or proximal aortic injury and these treatments will cause only temporary improvement with worsening again upon reaccumulation of blood. In this case, the treatment is thoracotomy and primary repair of the cardiac injury. Emergency thoractomy may be performed in the emergency department as a temporizing measure to give the patient time to make it to the OR when vital signs are lost, but overall mortality is high.

The critical transmitter at the junction where neurons meet skeletal muscles is acetylcholine (ACh). When a motor neuron is stimulated, it releases acetylcholine into the neuromuscular junction, binding to receptors on the muscle fiber's membrane. This binding triggers depolarization of the muscle cell, leading to muscle contraction. Thus, acetylcholine is essential for communication between the nervous system and skeletal muscles.
