Muscular System
The muscular system allows humans to move. Muscles also provide strength, balance and heat.

Longitudinally and circularly arranged layers in muscle?
Smooth muscle tissue has longitudinally and circularly arranged layers.
What muscle works in a pair with the biceps brachii?
A muscle fiber gets a signal to move from a nerve and then it moves!
What smaller hip muscle is commonly used as an injection site?
my anatomy and physiology teacher has told my class multiple times that the smaller hip muscle that is a common sight for injection is the gluteus medius.
gluteus medius
the skeletal system give blood from the heart to the circulatory system to keep homeostasis
Why does the belly of a muscle bulge when contracted?
Because the volume of the muscle has to stay pretty much the same. It can be either long and slender or short and stubby. It's like having two bricks - you can either stack them on top of each other or lay them out in a row. The volume stays the same anyhow.
What muscle action is not under your control?
The muscles that you control to do activities are your voluntary muscles. They allowed you to type this question, to read the web page, and do all sorts of other things.
What helps heal a ruptured quadriceps tendon?
what you should do is heat it ice it and stretch a lot don't take any inflamitory pills or anything like that because just stick to the old way as I have said heat it ice it and put some icy hot on it .
What is the dome-shaped muscle that aids in breathing?
The muscle you are referring to is the diaphragm. It also separates the thoracic cavity from the abdominopelvic cavity.
Striations of skeletal muscle are produced by?
Skeletal Muscle (as well as Cardiac Muscle) have striations do to their sarcomere's anatomy. The sarcomere is the functional unit of the muscle and appears striated because the different thick and thin filaments present.
The classification of muscles are based on five factors and they are location, neural control, anatomy, output, and typical activity. Examples of muscles include skeletal muscles, involuntary muscles, and normally relaxed muscles.
How many muscles are in the fingers of one human hand?
approimately there are
34 muscles in the fingers and thumbs
17 in the palm of the hand
18 in the forearm.
I'm not sure if these numbers are totally accurate but they are close.
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.
no
not
cardiac muscle
Does creatine make you gain non-muscle weight?
The main function of creatine is to act as a buffer for ATP. ATP is the main form of energy consumed by your muscles, where the food you eat such (e.g. glucose) is broken down and used in a series of metabolic reactions to produce ATP. ATP is used in the cross-bridge actinmyosin cycle in muscle cells, and is consumed with each muscle contraction. However, ATP pools in the body are relatively small and are therefore consumed in a short period of time (a matter of seconds) during intense, anaerobic and alactic exercise. Creatine comes into play here where CrP (creatine Phosphate) re-establishes ATP as it is consumed by muscle as it supplies it with additional high energy phosphates.
In short, creatine acts as a buffer to reduce the rate of ATP depletion during anaerobic and alactic erercise. Creatine occurs naturally in the body in relatively small amounts and the 'body building' supplements just provide an additional supply of creatine, this enables you to work harder at the gym. It does not directly contribute to muscle weight gain, however enables you to work your muscles harder.
Is raising your arm a voluntary or involuntary action?
voluntary, a typical person can move it at will.
The delicate connective tissue that surrounds the skeletal muscle fibers and ties adjacent muscle fibers together is the endomysium.
What causes movement at the knee joint?
In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.

Our bodies have different types of tissues that are used to connect all of our different parts. Bones are connected to other bones by special tissues called "ligaments." But when bones are connected to muscles, the special tissues are called "tendons."
Tendons are very strong. They are built from long strands of protein and they are not very stretchy. When a muscle pulls, they pull too and they can move our bones.
We have tendons in many parts of our bodies: wrists, elbows, thumbs, shoulders, knees, head, legs, and heels. Tendons almost always connect bone to muscle, but sometimes they connect muscle to other things, like an eyeball!
Achilles Heel
You can find at least one tendon in your body pretty easily. It's called the Achilles tendon and it connects your calf muscles (the back of your lower leg) to your heel.
While sitting, lightly pinch the back of your leg, right above your heel. (If you were standing, you might tip over!) Wave your foot, like it was your hand. You'll feel something moving in the back of your leg. You might have thought this was a bone, but it's actually a tendon!
The Achilles tendon is the strongest tendon in our bodies. Why do you think it needs to be so strong?

Where is smooth muscle located?
It is not found in human bodies and is only found in monkeys in the dense forest in Pakistan and only 3 of these monkeys are left and were found in Osama Bin Ladens Cave
What is the large muscle that brings air into the lungs?
Diaphragm, the spelling of that was kind of a guess, but you get what I mean. :)
Is the thigh muscle voluntary or in voluntary?
The thigh muscle is voluntary because you can move it up and down, and side to side.
