The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [ 1 ] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle ) can be completely autonomous.
ophthalmic artery, lateral muscular branch trochlear nerve [CNIV] abducts, intorts, and depress eye: right medial, superior, and inferior recti (superior and inferior oblique muscles are the synergists) 2 1 oblique, inferior: head, extraocular (left/right) orbital surface of maxilla, lateral to lacrimal groove
Muscle is a soft tissue, one of the four basic types of animal tissue.There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle.
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [ 3 ] [ 4 ] [ 5 ] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [ 6 ]
Versus the general population, persons manifesting muscle dysmorphia are more likely to have experienced or observed traumatic events like sexual assault or domestic violence, [7] [15] or to have sustained adolescent bullying and ridicule for actual or perceived deficiencies such as smallness, weakness, poor athleticism, or intellectual inferiority.
Muscular hypertrophy can be increased through strength training and other short-duration, high-intensity anaerobic exercises. Lower-intensity, longer-duration aerobic exercise generally does not result in very effective tissue hypertrophy; instead, endurance athletes enhance storage of fats and carbohydrates within the muscles, [ 5 ] as well as ...
