Increasing Muscular Density and Muscle Tone In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive part contraction of the muscles, or the muscle's resistance to passive stretch during resting state.

muscle mus·cle (mŭs′əl) n. 1. A tissue composed of fibers capable of contracting to effect bodily movement. 2. A contractile organ consisting of a special bundle of muscle tissue, which moves a particular bone, part, or substance of the body: the heart muscle; the muscles of the arm. 1  3. Muscular strength: enough muscle to be a high jumper. 4. Informal Power or authority: put some muscle into law enforcement.

- Contractility refers to the capacity of muscle to contract or shorten forcefully. Excitability means that muscle responds to stimulation by nerves and hormones, making it possible for the nervous system and, in some muscle types, the endocrine system, to regulate muscle activity.

Muscle contraction Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position. muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same. In contrast, a muscle contraction is isotonic if muscle length changes but the muscle tension remains the same. Furthermore, if the muscle length shortens, the contraction is concentric.

- Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.uscle contractions can be described based on two variables: length and tension. A muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same. In contrast, a muscle contraction is isotonic if muscle length changes but the muscle tension remains the same.

- (June 2013) In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state.

- By our definition, tone is perceived by an examiner but not directly perceived by the patient. Assessment should include palpation of muscles to estimate the resting (baseline) state of muscle activation. Note, however, that tone is not rated by the presence or absence of muscle contraction at rest.

- Muscle tone is a major factor in how a premature baby’s motor skills develop. A full-term baby usually has normal muscle tone. He’s able to keep himself in a nicely flexed position with arms and legs tucked into the body. A premature baby often has less muscle bulk and is usually “hypotonic”.

- Contraction and relaxation of a skeletal muscle or group of muscles in which the force generated by the muscle is equal to the resistance. There is no change in muscle length, and no movement results. See: illustration Synonym: muscle-setting exercise; static exercise

- Peripheral hypotonia: decreased muscle tone that can occur as a result of nerve damage between the spinal cord and muscle, or due to disruption in the communication between the end of the nerve and the surface of the muscle, or abnormalities in the muscles themselves.

- The muscles of the blood vessels need to be given a constant nervous stimulation to maintain a resting level of contraction. This phenomenon is known as vasomotor tone. It maintains the diameter of the blood vessels, and therefore it plays a vital role in maintaining the blood pressure.

Top 20 Doctor insights on: What Does A Torn Muscle Feel Like Muscle (Definition). It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes.

muscle A body tissue composed of elongated cells (called muscle fibers) that contract to produce movement. In vertebrate animals, voluntary movement is produced by the action of muscles on bone. Movement of the muscles of the heart and other organs is involuntary and controlled by the autonomic nervous system.. A tissue composed of fibers capable of contracting to effect bodily movement. 2. A contractile organ consisting of a special bundle of muscle tissue, which moves a particular bone, part, or substance of the body: the heart muscle; the muscles of the arm.

- Now we have some confusion as many people believe that muscle tone is all about fitness. Muscle tone refers to the amount of tension or resistance to movement in a muscle. Muscle tone is what enables us to keep our bodies in certain position or posture. Changes in muscle tone is what enables us to move.

What is Muscle Tone? Children with high muscle tone may have delayed gross and fine motor skill development, have difficulty “relaxing” his/her muscles, maintain a fisted hand beyond 6 months of age, or may present with very stiff legs that appear to move like scissors when standing or attempting movement.

muscle tone Pathologically, loss of tone (flaccidity) can be caused, e.g. by peripheral nerve damage, and exaggerated tone (spasticity) by overstimulation, e.g. when the activity of the relevant lower motor neurons is released from higher CNS control in spinal injury.

Tonic (physiology) Tonic (physiology) From Wikipedia, the free encyclopedia. Tonic in physiology refers to a physiological response which is slow and may be graded. This term is typically used in opposition to a fast response. For instance, tonic muscles are contrasted by the more typical and much faster twitch muscles, while tonic sensory nerve endings are contrasted to the much faster phasic sensory nerve endings. 1 Tonic muscles.

What Is Muscle Tone? What Is Muscle Tone? What is low muscle tone? was a question often asked by parents when I worked as a pediatric occupational therapist in private practice. They often confused tone with muscle strength. Here is a simplified overview and a brief description of normal, high and low tone and their effect on movement. Stolov, 1966, defined the tone in the muscle as the resistance of the muscle to passive elongation or stretching (1). In other words, it is the state of muscle tension inside a muscle or muscle group when it is at rest.
