Muscular System

The smooth muscle found in the muscularis layer of the intestines is found in layers.

There are some radial muscles that exist in the eye. Radial muscles have a similar structure to that of spokes on a bike, radiating outward from their source. The extraocular muscles of the eyes connect to the eye in several different locations around it to allow movement in different directions according to which extraocular muscle contracts.

you use your quadriceps all the time. You never stop using them, even if you are sitting you are always moving.

Sleep deprivation can lead to psychosis or even death. You need sleep to consolidate your memories and even to maintain a healthy body weight.

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.

to walk on it you should relax or use cruthes to guide yourslef around The worst thing to do would be to keep using the muscle when you already know it's torn. You damage the muscle more if you keep applying pressure to it. The best thing to do is to rest, add ice, apply compression, and elevate the muscle. If it's really bad, you should see a doctor.

Myasthenia gravis is an autoimmune disease marked by muscle weakness and fatigue. The symptoms are activated when the immune system produces antibodies that interfere with the transmission of nerve signals to skeletal (voluntary) muscle. As a result, the affected muscles cannot contract normally.

Muscle glycogen is an important fuel for contracting skeletal muscle during prolonged

strenuous exercise, and glycogen depletion has been implicated in muscle fatigue. It is also

apparent that glycogen availability can exert important effects on a range of metabolic and

cellular processes. These processes include carbohydrate, fat and protein metabolism during

exercise, post-exercise glycogen resynthesis, excitation--contraction coupling, insulin action

and gene transcription. For example, low muscle glycogen is associated with reduced muscle

glycogenolysis, increased glucose and NEFA uptake and protein degradation, accelerated

glycogen resynthesis, impaired excitation--contraction coupling, enhanced insulin action and

potentiation of the exercise-induced increases in transcription of metabolic genes. Future

studies should identify the mechanisms underlying, and the functional importance of, the

association between glycogen availability and these processes.

I am not sure myself (the only reason I'm writing this), but I -do- recall seeing a video about healthy eating and exercising in seventh grade that explained how it worked, and I think it mentioned that the "bulge" is a dedicated fat pocket for the muscle to use in case it's needed.

Any dietists or physicians that know the real answer is free to correct me

A muscle is a tissue that is composed of cells with the ability to contract and relax. Because of those two specialized actions, the body is able to move. The muscles in the human body are specialized into three different functions:

Skeletal muscle is striated (striped in appearance) and allows the skeleton to move voluntarily. (walking, waving, typing this answer)

Smooth muscle is responsible for involuntary movement of the organs. (the muscles that tell you it's time to go to the bathroom)

Cardiac muscle is just that. Cardiac means heart. It is the muscle that pumps blood around your body.

WHEW! I passed medical terminology this quarter with flying colors but that was a lot of typing. I only got a c- in typing. :)

True

One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.

The skeletal muscle is a type of the visceral muscle.

The rectum is a portion of the end of the colon just before the anus and is controlled by involuntary muscles (smooth muscle). I believe the anal spincter or rear end opening has 2 types of muscles. The internal anal sphincter is involuntary fortunately and keeps us from social embarrassment. The external anal sphincter is voluntary and allows us to properly time the release of gas at the right moment in a conversation.

Eversion/valgus

The deltoid ligament is medial thus it will resist forces that press the foot laterally (prevent eversion).

Tendons join muscle to bone, and muscles sometimes attach to each other. They are called functional muscle groups, or synergists.

pivot point or fulcrum are the joints in the muscle.

quite a hard one to be honest. try full range endurance exercises when you do 15-25 repetitions of them but on a light weight. u will tone the muscle. but takes time. triceps are a hard muscle to train and there are 3 heads of a tricep muscle. try isometric exercise. i.e holding wall pressup. as if u are pushing the wall., that should strengthen them too but implement isotonic exercises wich are exercise where you are chaning the mucle at an angle. i.e dips, extensions

Yes, smooth muscle is involuntary muscle, meaning it will cause actions that you don't have to think about. For example, your vasculature is surrounded by smooth muscle to allow dilation or constriction of blood vessels to help control blood pressure and shunt blood away from or to certain regions of the body.

The deltoid is an example of skeletal muscle.

Some examples of smooth muscle is the muscle lining the GI tract, blood vessels, and the muscles in your eyes that dilate or constrict your pupil.

Cardiac muscle is only found in the heart.
