The neck is a common area in which to develop pain from desk work. Looking at a computer monitor, we often jut our neck forward rather than tucking in our chin, as we should.
To prevent or correct RSP, individuals should maintain good posture when performing daily tasks, and take frequent breaks when necessary. Regular exercise is also useful in strengthening the upper back and neck muscles. Postural alignment, pain and discomfort will be reduced to improve our overall health and wellbeing.
Turtles, such as Trachemys scripta elegans, have complementary muscles within the neck that show a potential inverse trend of fiber type percentages (one muscle has high percentage of fast twitch, while the complementary muscle will have a higher percentage of slow twitch fibers). The complementary muscles of turtles had similar percentages of ...
Super Slow is Hutchins' trademarked name for the High intensity training approach advocated by Arthur Jones. It is based on ideas from the 1940s and 1960s called 10/10 "muscle contraction with measured movement" and implemented using fixed weight Nautilus machines. In more recent times, such "Time Under Load" ideas have seen a renaissance with ...
The muscle fibers belonging to one motor unit can be spread throughout part, or most of the entire muscle, depending on the number of fibers and size of the muscle. [ 2 ] [ 3 ] When a motor neuron is activated, all of the muscle fibers innervated by the motor neuron are stimulated and contract.
Malnutrition first causes fat loss but may progress to muscle atrophy in prolonged starvation and can be reversed with nutritional therapy. In contrast, cachexia is a wasting syndrome caused by an underlying disease such as cancer that causes dramatic muscle atrophy and cannot be completely reversed with nutritional therapy.
The platysma muscle is a broad sheet of muscle arising from the fascia covering the upper parts of the pectoralis major muscle and deltoid muscle. Its fibers cross the clavicle, and proceed obliquely upward and medially along the side of the neck. This leaves the inferior part of the neck in the midline deficient of significant muscle cover.

Athetosis can vary from mild to severe motor dysfunction; it is generally characterized by unbalanced, involuntary movements of muscle and a difficulty maintaining a symmetrical posture. The associated motor dysfunction can be restricted to a part of the body or present throughout the body, depending on the individual and the severity of the ...
