Decrease in the size of cells, tissues, or organs. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise, or disease intrinsic to the tissue it self. Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic.
These 10 animal facts will amaze you The thenar region of the palm refers to the group of muscles in the thick pad just underneath the thumb. Thenar atrophy is an eroding of muscle tissue, which can impair control over the thumb and leave the hand disfigured. The problem can be a complication of several different conditions and disorders, including carpal tunnel syndrome, acromegaly, or direct trauma to the wrist or thumb.
In addition, atrophy can occur if the wrist and hand are immobilized in a cast for several weeks or months. Treatment measures are usually focused on curing or managing the underlying cause and gradually rebuilding strength through guided physical therapy.
Three muscles, several tendonsand a small area of protective cartilage tissue are found in the thenar region. The muscle group that controls the movement of the thumb is stimulated by a long, vital structure called the median nerve.
Most cases of atrophy have to do with problems related to the median nerve. When it is compressed or severed, the resulting lapse of electrical activity in the hand means that the muscles are never exercised; unstimulated muscle tissue wastes away over time. Ad Advanced carpal tunnel syndrome is the most common cause of thenar atrophy.
Inflammation of the wrist joint caused by frequent overuse narrows the passageway of the median nerve, resulting in numbness, weaknessand chronic pain.
Atrophy can occur in the late stages of carpal tunnel, which may cause partial or total paralysis of the region.
Acromegaly is a hormonal disorder that affects the way body tissues grow, including those in the wrist and thenar region. Overgrowth of bone tissue may put pressure on the median nerve and other nerve branches elsewhere in the body.
Atrophy of the thenar region is a common complication of median nerve compression. Prolonged immobilization is another potential cause of atrophy in patients who break their thumbs or wrists.
The hard casts use to keep bones from moving can also impede muscle movement; as bones heal, unused muscles waste away.
Thenar atrophy due to any cause is usually very noticeable. There might be an obvious dent in the palm or along the outer edge of the base of the thumb. At rest, the thumb may be fixed in a rigid position across the front of the palm.
In cases of severe atrophy, it is impossible to bend or move the thumb at all. A medical professional can usually identify the cause of atrophy by asking about a patient's medical history and taking diagnostic imaging scans of the hand.
Depending on the underlying condition, a patient may need to take specialized medications or undergo surgery to decompress the median nerve. Physical therapy is important in the recovery stages to safely and effectively rebuild muscle mass in the thenar region.
A healthcare professional may also decide to schedule a clinical electro-stimulation procedure to massage and work the muscles. With treatment, most cases can be reversed.Osteoarthritis, also known as "wear and tear" arthritis, occurs when the cartilage that cushions and protects the ends of your bones gradually wears away.
This leads to pain and stiffness that worsens over time, making it difficult to do daily activities. that indicate bone-on-bone friction. muscle loss (atrophy), and signs that other. Synapsis of Osteoarthritis, Muscle Atrophy and Osteoporosis Essay In this paper I will be discussing Osteoporosis, Osteoarthritis, Muscle Atrophy and the effects they would have on an eighty year old woman.
The women’s physical condition is thin, small boned, and is Caucasian. Osteoarthritis (OA) also known as degenerative arthritis or degenerative joint disease or osteoarthrosis, is a group of mechanical abnormalities involving degradation of joints. Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide.
In animal models of the disease, as well as in ALS patients, it has been shown that the neurodegeneration starts at the axonal synapse, and skeletal muscle denervation is observed before motor neuron loss in the spinal cord (1,43).
Muscle growth that occurs after birth occurs by enlargement of existing muscle fibres. Due to increased production of myofibrils, mitochondria, sarcoplasmic reticulum, and other organelles. Results from forceful, repetitive, muscular activity - promoted by growth hormones (kids) and testosterone (adults).
Physical activity and Mediterranean diet based on olive tree phenolic compounds from two different geographical areas have protective effects on early osteoarthritis, muscle atrophy .
