A concentric contraction causes muscles to shorten, thereby generating force. Eccentric contractions cause muscles to elongate in response to a greater opposing force. Isometric contractions generate force without changing the length of the muscle.
What is the medical term that means pertaining to muscle?
[mus ́ku-lar] 1. pertaining to a muscle.
Which medical term best describes shortening or tightening of a muscle?
A muscle contracture involves the shortening and tightening of the muscles.
What is it called when a muscle in your body gets shorter and thicker?
(excitability) muscles receive and respond to stimulation. Contractability . allows muscles to change shape to become shorter and thicker. Extendibility.
What term best describes the ability of muscle to shorten forcibly when adequately stimulated?
Contractility is the ability to shorten forcibly when ade- quately stimulated. This ability sets muscle apart from all other tissue types. Extensibility is the ability to extend or stretch. Muscle cells shorten when contracting, but they can stretch, even beyond their resting length, when relaxed.
What is shortening of a muscle?
What it means is that one or several joints are limited in their mobility, or that a muscle is unable to perform to its full physical capacity . ... This is caused by a limitation of the natural range of motion (ROM). The structure of a muscle. However, a real shortage does actually occur.
Which muscle cells have the greatest ability to regenerate?
Smooth cells have the greatest capacity to regenerate of all the muscle cell types. The smooth muscle cells themselves retain the ability to divide, and can increase in number this way.
What does Fasciodesis mean?
(făsh′′ē-ŏd′ĕ-sĭs) [′′ + Gr. desis, binding] Surgical attachment of a fascia to a tendon or another fascia .
Which suffix means pain or suffering?
-algia means pain and suffering.
What is the medical term for inflammation of many nerves?
External Websites. Neuritis , inflammation of one or more nerves. Neuritis can be caused by injury, infection, or autoimmune disease.
What is the ability of the muscle to be stretched without tearing?
Extensibility – ability of a muscle to be stretched without tearing; Elasticity – ability to return to its normal shape.
What are the 4 types of muscles?
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...
- Cardiac muscle – the muscle specific to the heart.
What is the strongest muscle in the human body?
The strongest muscle based on its weight is the masseter . With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What are the two most important pathways by which ATP is generated in muscle cells?
Glycolysis converts glucose to pyruvate, water and NADH, producing two molecules of ATP. Excess pyruvate is converted to lactic acid which causes muscle fatigue. Cellular respiration produces further molecules of ATP from pyruvate in the mitochondria.
What is the ability of the muscle to respond to stimuli?
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended.
Which ion is important for muscle contraction?
Thus, Calcium plays an important role in muscle contraction. The role of magnesium is to form a MgATP complex to bind to a myosin active site, thus promoting actomyosin dissociation. Both calcium and magnesium are required during chemical events and muscle contraction.
