The six basic movements of skeletal muscle include flexion, extension, abduction, adduction, rotation, and circumduction. Flexion decreases the angle between body parts, while extension increases it. Abduction involves moving a limb away from the midline, and adduction brings it back toward the midline. Rotation refers to turning a body part around its axis, and circumduction is a circular movement that combines flexion, extension, abduction, and adduction.
Different muscles are involved in different movements.

There are actually six types of seizures. 1. Grand Mal - Unconsciousness, convulsions, muscle rigidity 2. Absence - Brief loss of consciousness 3. Myoclonic - Sporadic jerking movements 4. Clonic - Repetitive jerking movements 5. Tonic - Muscle stiffness and rigidity 6. Atonic - Loss of muscle tone
The muscle that attaches to the cartilage of ribs 5, 6, and 7 is the rectus abdominis. This muscle is part of the anterior abdominal wall and plays a key role in flexing the trunk and stabilizing the pelvis. It connects to the costal cartilages of these ribs, contributing to its function in movements like sitting up and bending forward.
Levels of organization of muscle ( in decreasing order)1. Muscle: Group of muscle fascicles, which work together to cause one specific movement.2. Fascicle: Bundle of muscle fibers3. Muscle fiber: Muscle cell: cylindrical cell of skeletal muscle. It has many nuclei, therefore it is called multinucleate.4. Myfibril: Contractile fibers found within a muscle cell. It has 100 - 1000's of muscle cells in each muscle fiber.5. Sarcomere: Structural and Functional unit of the muscle. It is the smallest unit of a muscle that is able to contract.6. Actin and myosin filaments: Filamentous proteins which can interact together to cause contraction.
hold on, let me look for it........... its skeletal muscle because i went onhttp://graphics8.nytimes.com/images/2007/08/01/health/adam/19917.jpg and it shows the smooth muscle, skeletal muscle, and cardiac muscle...and the skeletal mucle is closer to your hand than any other muscles. if u dont believe me go on that website (actually its not a website, its on google images).
Calcium is absolutely necessary for muscle contraction (both skeletal and cardiac) and for bone and teeth formation. 99% of the calcium in your body is stored in your teeth and bones. It is thought that you should drink as much as 6 glasses of milk a day. That much will not cause gall stones as once was thought.
6 steps in a muscle contraction
There are more than four major functions of the human bodies muscles. You may be able to group them together based on what specifically is being asked of you. Major Muscle Functions: 1.) Producing Movement 2.) Maintain Body Posture and Body Position 3.) Stabilize Joints 4.) Generate Heat 5.) Make up a layer of organs and blood vessels to dilate and constrict 6.) Contract the heart and cause blood to be pumped throughout the body.
You are now 19 weeks pregnant -- almost halfway there! Nineteen weeks into your pregnancy, your baby is about 5.2 to 6 inches long and weighs about 7 ounces (about the weight of an average orange). Your baby is now able to make conscious muscle movements, such as sucking his or her thumb, in addition to involuntary muscle movements. This week, you may feel these movements, which are known as quickening. This may feel as if you have butterflies or a growling stomach; a lot of first-time mothers may not feel the classic kicking until they are 26 weeks pregnant.

Muscle cells lack the enzyme glucose-6-phosphatase, which is required to pass glucose into the blood, so the glycogen they store is destined for internal use and is not shared with other cells. (This is in contrast to liver cells, which, on demand, readily do break down their stored glycogen into glucose and send it through the blood stream as fuel for the brain or muscles).
