Muscular System

Bell's Palsy is one. Dysfunctional cranial nerve causes partial facial paralysis

It is air that does it, as well as the rib muscles themselves. The diaphragm contracts, expanding the internal area of the thoracic (chest) cavity, causing a drop in pressure. Air is then drawn through the nose into the lungs, which expand, causing the ribs to move to accomodate this.

You use approximately 200 muscles to walk.

they both involve mutations in which fat replaces normal tissue

Peroneus (fibularis) longus muscle and Peroneus (fibularis) brevis muscle

Deltoid

The endomysium is the connective tissue that surrounds each muscle fiber (cell). The perimysium encircles a group of muscle fibers, forming a fascicle. The epimysium encircles all the fascicles to form a complete muscle.

This could be caused by a number of reasons, ranging from muscle fatigue and lactic acid build up to low sodium in the area to deep vein thrombosis (DVT) which is a lot more serious. My advice is go and see your doctor if you're not sure.

The responsibility of the muscular system is the movement of the human body. There are at least 700 muscles that make up approximately half of a person's body weight. Each muscle functions in different ways but they all contribute to proper movement.

you can divide your thigh in to 2 parts with front portion being called quadriceps(includes muscles called vastus intermedius,vastus lateralis,vastus medialis,rectus femoris) and back portion called hamstring(includes muscles called semitendinosus,semimembranosus,bicep femoris)

The heart is the most important muscle of the body because it is the organ that pumps the blood throughout the body to carry out oxygen and nutrients, and helps collect and eliminate carbon dioxide and other wastes from the body.

First of all, muscles are not the source of body heat. It is the metabolism that they undergo that produce heat. Each time a muscle move (involuntary, voluntary, or cardiac), a certain amount of calorie is required to be burned to effect a muscle contraction. For carbohydrates and proteins as fuel, we extract 4 calories per gram., For fats, it's about 9 calories per gram, though the body never directly always use the latter because of toxic by-products at the end of the reaction. The successive contraction and relaxation of muscles, as in running or exercising might give an idea to a layman that the muscles are the major source of body heat, but in the medical and scientific discipline, it is not. Teachers, especially Science teachers, must be trained in English as well, to be able to deliver to their pupils the exact skills, knowledge, and training in a systematic way, including asking questions that are not out of order.

can u damage cheek muscles by piercing into it.

Skeletal muscles are attached to bones which make up the skeleton. They are attached to the bones by tendons. The tendons are made out of tissues that run through the muscular tissue and come together at the end forming tendons. The major function of the skeletal muscles is movement. Contraction of the fibres (cells) in the skeletal muscle generates tension which is transmitted through the tendons. Pairs (or more) of muscles generating tension on the tendons will move the bone. Skeletal muscles are also used in the maintenance of posture as the muscles have to contract to keep the body up right. An other function is the by product of movement; heat. The heat produced during the contraction of muscles, is an important homeostatic mechanism as it helps to maintain the body's core temperature.

Hope this helps, have just finished a massive assignment on this subject!

A misunderstanding.

That's not how breathing actually works. Your rib cage is all but immobile.

An action potential send by a motor neuron arriving at the neuromuscular junction. Then this causes the muscle sarcolemma depolarizing and sending more action potentials into sarcomeres that release calcium ions from the sacroplasmic retinaculum. This causes the actin filaments to allow the globular heads of the myosin filaments to bind to them (like walking up a ladder) and shorten the muscle fiber into contraction.

cardiac and smooth muscles are involuntary skeletal muscles are voluntary.

smooths muscles are in you intestine and digestive tract usually cardiac muscles are in your heart skeletal muscles are connected to tendons and ligaments

Smooth muscle tissue isn't divided into specific muscles like skeletal muscle tissue is, but these organs have smooth muscle in them:

Stomach

Small intestine

Large intestine

Iris (of the eye)

Arrector pili (responsible for goosebumps)

Ureters

Bladder

Parts of the esophagus

Blood vessels

Bronchi and bronchioles (the airways in the lungs)

Uterus

Facial muscles are usually employed to display surprise.

The diaphragm is the main muscle of respiration. It is a dome shaped muscle with it's origin at the sternum, xiphoid process, coastal cartilage, 7th to 12th ribs and L2/3. It's insertion is the central tendon.

The long head from infra-glenoid tubercle, the medial convers most of the posterior area of humerus and the lateral from a ridge above the spiral groove. That is for the brachii Or do you mean Surae?

Rectus femoris

Vastus medialis

Vastus intermedialis

Vastus lateralis

Diaphragm seperates the respiratory system and the digestive system.

They contract very quickly
