The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso.
Spastic diplegia is a form of cerebral palsy (CP) that is a chronic neuromuscular condition of hypertonia and spasticity in the muscles of the lower extremities of the human body, manifested as an especially high and constant "tightness" or "stiffness", [1] [2] usually in the legs, hips and pelvis. [3]
Muscles affected in this way have many other potential features of altered performance in addition to spasticity, including muscle weakness; decreased movement control; clonus (a series of involuntary rapid muscle contractions often symptomatic of muscle over-exertion and/or muscle fatigue); exaggerated deep tendon reflexes; and decreased ...
In many people with SPS, muscle rigidity eventually progresses from the trunk to the limbs — first affecting muscles closest to the trunk, then further. [6] Stiffened limbs can affect a person's balance and gait, causing awkward 'statue-like' falls, where the affected person cannot put out their arms to soften the impact. [6]
The regions of the back of the arms, from superior to inferior, include the cervical region encompassing the neck, the acromial region encompassing the shoulder, the brachial region encompassing the upper arm, the olecranal region encompassing the back of the elbow, the antebrachial region encompasses the forearm, front and back
Upper-Body Stretches: Neck, Shoulders, Upper Back, Pecs, Arms, Chest. The upper body is where many people store tension and stress. “Our world and most of the activities we are participating in ...
The skeletal muscles of the body typically come in seven different general shapes. This figure shows the human body with the major muscle groups labeled. The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most ...
In regards to muscle, these include (but not limited to): Ischemia (restriction of blood flow) leading to the death of muscle tissue, as in Volkmann's contracture. Muscle injury leading to adhesions and fibrosis (internal scarring). Fibrosis occurs within a muscle or organ, whereas adhesions bind two separate tissues or organs together ...
